editor’s note

It’s not just an efficiency thing anymore

T

he market for energy management systems is probably a pretty good one to be in right now. Sales of software alone are set to grow exponentially over the next 10 years in response to energy prices and the need for building owners to have greater real-time control over their energy usage. This will be driven largely by the market for retrofits, of which the Asia-Pacific represents the second largest market in the world, one that is estimated to jump from 32% of the global market ($26 billion) in 2011 to 36% (nearly $55 billion) by 2020. But the world’s biggest companies are going a step further by developing concrete strategies for generating their own power. In fact, 70% of the world’s billion-dollar businesses are planning to put more time and money into generating their own power, growing their renewables portfolios and ramping up energy efficiency efforts, according to report from Ernst & Young. In this issue, we look at the progress being made in demand management and several methods gaining in popularity – thermal storage and cogeneration/trigeneration – as well as looking at the needs of a growing audience for building performance data. Specifically, how companies can turn the data from energy management systems into information or create context and visualisation that is meaningful to different groups. WME also looks at what claims to be the next wave in green buildings – the positive energy building – with Australia unveiling its first operating example this month. Maybe we’ll also start to move into bio-architecture, with buildings adopting measures such as the one currently being constructed in Germany with a live micro-algae façade for natural lighting and shading control. Perhaps not, given the success of the green roof movement here to date, although this could be about to change with metrics being developed to determine their energy saving potential. More on that in the next issue.

news : economic growth

Time to embrace the end of economic growth: panel A panel discussion was recently held by sustainability specialist firm Net Balance to discuss whether society has reached a “new normal”, with no real prospect of perpetual economic growth as we adjust to the burden of burgeoning debt and our natural limits. The discussion heard from Richard Heinberg, an internationally recognised expert on peak oil and author of the book The End of Growth, in which he explores the global financial crisis and how future growth is likely to be constrained by dwindling resources, increasing environmental degradation and growing debt. An eternal realist, Heinberg was clear that despite what politicians, media and economists might tell us about economic recovery, economic growth is over. According to him, “the sooner we recognise this reality the better it will be for the planet and for the economy”. Heinberg said the winding down of economic growth, which began in the 1970s, was assumed by economists to go on indefinitely, clearly an “absurd notion”. “A continual rise in GDP growth, population growth and consumption backed by government and central bank financing created a bubble that kept growing while at the same time resources kept shrinking,” he added. History is on our side: Gilding Attendees then heard an optimistic viewpoint from Paul Gilding, former CEO of Greenpeace International and these days a writer, advisor and advocate for action on climate change. His book The Great Disruption explores the idea that we need to lead, inspire and motivate action globally on the transition of society and the economy to sustainability. Gilding noted: “It is easy to get overwhelmed by the complexity of the challenge ahead of us, it seems quite impossible to imagine ... because we are talking about eliminating the coal, oil and gas industries from the economy within 20 years and reducing levels of climate change to a reasonable level.” The reason Gilding believes the world can get itself out of this hole

Gilding: an optimistic viewpoint.

is because we have been there and done that, namely during World War II. “If you were living in that time you couldn’t possibly imagine the scale of economic transformation that occurred. The US went from 1.9% of GDP to 37% GDP in military spending while the country grew throughout five years,” said Gilding. “The advantage we have this time around is that there is nothing we need to do that we don’t know how to do, this does not require any breakthrough thinking”.

: carbon markets

Australia-California alliance on regional and global carbon markets Australia and California have agreed to work together towards the development of regional and global carbon markets. They will also exchange comparative experiences on climate policy and explore options for linking carbon markets over the longer term. Visiting the US for clean energy and climate talks, Parliamentary Secretary for Climate Change and Energy Efficiency Mark Dreyfus announced the formation of an ongoing working relationship after meeting with members of the Californian Office of Governor Edmund Brown Junior. He also met officials from the California Environmental Protection Agency and the Californian Air Resources Board. The arrangement will provide a forum for sharing experience on climate policy, including comparative experiences in emissions trading in Australia and California. “California has long been at the forefront of US efforts to reduce carbon pollution. “What happens here is watched closely by others states and nations,” said Dreyfus, who is representing Australia at the Major Economies Forum on Climate and Energy in New York.

“California’s cap and trade program starts on January 1, 2013, and the first auction of carbon allowances occurs in November,” said Dreyfus “By 2015 the program will be the world’s third largest emissions trading market, after the EU and Korean ETS, covering 85% of California’s emissions.” California’s cap and trade program has some similar design features to Australia’s, covering around 350 businesses. Other areas of mutual interest include methods of analysis, measurement and inventory, approaches to mandatory reporting and verification, and methods of market monitoring. While in California, Dreyfus also met industry representatives from Chevron, Rio Tinto, Pacific Gas & Electric Company and the Agriculture Council of California, as well as the American Carbon Registry. “Californian industry is getting ready for the cap and trade program. They are putting in place forward-looking business strategies that will reduce carbon emissions and give them a competitive edge in the market,” said Dreyfus. BEN-global.com: California

Investa launches continuous environmental reporting online In a first for the Australian property industry, Investa Property Group has introduced continuous reporting on the environmental performance of all buildings in its office portfolio in the form of online building scorecards. Investa’s move means tenants and investors can review the performance of the portfolio and individual buildings nine months earlier than normal. Sustainability reports are typically published only once a year. Quarterly environmental performance data is now being made available on the Investa website, showing the most recent results as well as the predicted annual portfolio result. This gives investors, tenants and building occupiers current and timely information about how resources

and costs are being managed across Investa’s portfolio. Commenting on the initiative, general manager sustainability, safety and environment at Investa Craig Roussac said: “Open and timely reporting encourages scrutiny and engagement from tenants and occupiers, especially where buildings are not performing to their optimal potential.” The reports provide: • quarterly figures of the electricity, gas and water use per square metre of the portfolio, nine months earlier than normal; • quarterly scorecards for buildings within Investa’s office portfolio; and • a window into the day-to-day tuning of buildings for research purposes and sector improvement. Maintaining building scorecards is a significant step forward in active building ownership and

Tenants, who typically control more than half of a building’s energy consumption, can also use this information in collaboration with owners to save costs and create more comfortable, productive work spaces for employees.

Victorian EPA goes back to the future on air-quality control EPA Victoria has partnered with CSIRO to take a scientific snapshot of the air we’ll be breathing in the future. The EPA has just released its interim report Future Air Quality in Victoria – a study undertaken with the peak science research body to identify trends in Melbourne and Geelong in decades to come. EPA CEO John Merritt said modelling of future air quality impacts used a combination of emission, weather and population data from a variety of sources. “EPA’s role is to monitor air quality, which can be impacted by industrial activity, transport and domestic activities,” said Merritt, who added that the study was a “futuristic snapshot” of air quality for Victoria’s two

During this time we have seen a vast improvement to air quality. With the use of EPA’s new air quality model, we will be able to predict pollution sources which will have the greatest effect on future air quality.” The information gathered in the study will be used to help government develop policies for

Australia has come out ahead in its recovery and recycling rate for newsprint for 2012, keeping with a steadily high trend set in recent years. According to a report from the Publishers’ National Environment Bureau, 77.7% of all Australian newsprint was recovered compared to a 70% recycling rate in Europe. Both Tasmania and South Australia retained their lead compared with other states. Despite newsprint consumption falling by almost 10% in 2011, recovery rates remain high.

The study’s findings highlight that emissions from large industrial sources, including sulphur dioxide, will continue to be well-managed through environmental legislation into the future. Using climate modelling provided by CSIRO, the study also considers climate-related impacts. On the basis of this modelling, it is predicted that summer ozone pollution - a gas that can be harmful to the lungs, particularly in the elderly and

As part of the ACT government’s plan, which aims to reduce carbon emissions by 40% from 1990 levels by 2020, solar photovoltaics have emerged as one of the key pillars of energy supply in the territory. In announcing the plan for an energy transformation, Minister for the Environment and Sustainable Development Simon Corbell was clear the switch to renewables was an environmental

and economic prerogative. “Strong action on climate change is affordable,” said Corbell. “And the value of energy and fuel savings can greatly, if not entirely, offset required investment costs.” One of the methods to achieving the goals, set out in the ACT plan, is to encourage rooftop photovoltaics. The government has also

committed to funding a three-year demonstration project in storage, focusing on hydrogen fuel cells and also batteries in electric vehicles, and how it can work with distributed small-scale photovoltaic installations. The ACT is the location of a 20MW photovoltaic power plant currently in development. The contract for power plant was awarded to Spanish firm FRV earlier this year.

The actions outlined by the order will help spur investment in US industrial energy efficiency, which will reduce greenhouse emissions, create jobs and strengthen manufacturing competitiveness by decreasing energy bills. The order reinforces domestic energy market and regulatory developments that are converging to make conditions for CHP investments more favourable than they have been for decades. Key contributing factors include federal environmental regulations and rapidly changing energy economics, particularly regarding US shale gas development.

Europe accounted for two thirds of the worldwide newly installed photovoltaic capacity in 2011, with 18.5 gigawatts. Its overall PV capacity totalled 52GW, said a study published by the European Commission’s Joint Research Centre. About half of corporate executives polled – 46% – said they used sustainability valuation methods to compare and prioritise their sustainability initiatives, according to a PricewaterhouseCoopers survey. Hotel operator Hilton has received a Green Power Leadership award from the United States EPA in recognition of its impact on green power by purchasing 315kWh annually. Lufthansa will team up with Australian bio-fuels company Algae.Tec to build a largescale plant producing aviation fuel from algae at a facility in Europe. The Union of Concerned Scientists in the US claimed 93% of Fox News and 80% of the Wall Street Journal opinion pages on climate change was inaccurate or misleading in relation to its importance and relevance. In 2011, the Fujitsu Group’s global carbon dioxide emissions totalled about 1.098 million tonnes, representing a reduction of 7.3%, or about 87,000 tonnes, and an 18.2% reduction on levels from the company’s 1990 baseline year. AkzoNobel has been ranked first in the chemicals “super sector” as part of the Dow Jones Sustainability World Indexes, achieving a total score of 93, moving up from second place. Ceres has released an online tool to help companies assess supply chain sustainability. Originally designed for the industrial goods sector, the tool can be useful for all companies seeking to strengthen supply chain engagement. It appears technically feasible for Long Island, New York, to have a 100% renewable, zerocarbon electricity supply by 2030, according to a report by Synapse Energy Economics Inc. The US government is significantly underestimating the costs of carbon pollution because it is using a faulty analytical model, according to a study published in the Journal of Environmental Studies and Sciences.

CFOs on sustainability

Airbus unveils latest vision

Nearly one half of chief finanial officers see sustainability as a key driver of financial performance and two-thirds are involved in driving strategies in their organisations, according to a global Deloitte survey of 250 CFOs, representing companies with more than $1 billion in annual revenue. The survey was conducted by Verdantix on behalf of Deloitte and included CFOs from 14 countries. It found the percentage of CFOs and chief operations officers accountable to their company’s board for sustainability issues nearly doubled in the past year from 20% to 36%. However, over the same period, the accountability for sustainability issues decreased for chief executive officers. As a result, CFOs have become increasingly focused on a number of sustainable operating practices, including tax and financial reporting and investments in technology that will further reduce the footprint of company travel, energy use and a range of other indicators.

Aircraft manufacturer Airbus recently released its latest instalment of the “Future by Airbus” report, its vision for a sustainable aviation industry in 2050 and beyond. For the first time, the report looked at how the aircraft was operated, both on the ground and in the air. Airbus noted there were already steps that could be taken today to enhance the sustainability of flight times. It found that if the Air Traffic Management (ATM) system and technology on board Airbus aircraft was optimised flights in Europe and the US could on average be about 13 minutes shorter, and the same could be said for flights elsewhere. And with continued improvements to aircraft design, alternative energy sources, and new ways of flying, these improvements can only increase over the following decades.

IKEA converts to LED Retailer chain IKEA announced it plans to convert its full lighting range to light emitting diode (LED) technology by 2016 - meaning IKEA will be selling only LED-based light sources as opposed to traditional sources. It will also change more than one million light sources inside its own stores to LED and other more “energy-efficient lighting”. “LED is a light revolution. With household electricity bills continuing to rise rapidly and global energy consumption increasing, a small LED bulb can have a very big impact,” said Steve Howard, chief sustainability officer for the IKEA Group. He also said that IKEA will be offering its LED product range at the lowest prices on the market. “This is building on our belief that everyone should be able to afford to live more sustainably at home”. © Aspermont Limited – courtesy WME

Agreement to reduce tariffs Sustainable Business Australia (SBA) has welcomed the decision made by economic leaders at the recent APEC meeting held in Vladivostok to reduce tariffs on environmental goods. “Many Australian businesses working in the ‘green’ space will benefit considerably from the decision taken at APEC on the weekend,” said Andrew Petersen, CEO of SBA. “Businesses who are already working towards green growth and trade liberalisation objectives will move forward significantly at lower cost because of this decision by the 21 APEC leaders.” The reduction of tariffs agreed on 54 out of 60 items nominated for a 5% tariff reduction will make products more affordable and create real opportunities for Australian businesses to invest in sustainable industries. “The decision will help stimulate trade in environmental products and thus lead to a society where environmental products are equally, or even more, attractive to use than others,” Petersen said.

THE WORD

Offset, game and match in the US As part of the US Open tennis tournament’s expanding efforts to go “green” this year, travel-related emissions were matched with carbon offsets purchased by a Norwalk Conn energy company. “We estimated and calculated player travel to the Open from all over the world, in the air and also on the ground,” said Lauren Kittelstad, a US Tennis Association senior manager. The push toward carbon-neutrality is one of several new projects under the Open’s fiveyear-old environmental initiative aimed at employees, players and the 700,000 fans flocking to the USTA Billie Jean King Tennis Center in Queens. Even the 26,000 credential-holding lanyards used by employees, media, police, VIP fans and others were made from recycled tennis ball cans from last year’s event.

Tighter control on plastics The Chinese government has been taking actions to rein in the waste plastic imports industry, first by imposing policies to tighten up the control of import and trade of scrap materials, and now by enacting a new regulation that bans improper recycling practices that may pollute the environment. According to a government announcement, the new rules will take effect in October and ban irresponsible handling of scrap materials, including such activities as using recycled plastic to make ultra-thin bags; using recycled plastic to make food-contact bags; and handling of hazardous waste without a special licence. For imported waste, the industry will be ordered to comply with all related policies and prohibited from activities such as importing unwashed, post-consumer scrap; transferring imported waste to a company other than what is licenced, including sending the materials to vendors for washing services.

California’s cap and trade trial California officials have completed a successful trial of its much-anticipated carbon trading scheme which will put a price on emissions from industrial facilities and power plants. The state’s Air Resources Board staged a mock greenhouse gas auction, in which heavy emitting companies pretended to bid for carbon permits in order to test out the system ahead of its official launch. California will roll out the platform on November 14, when more than 400 companies will be able to buy and sell tradeable carbon credits through quarterly auctions. A state-wide cap on carbon emissions will be imposed from 2013, before being gradually lowered year-on-year, providing firms with a financial incentive to curb their greenhouse gas emissions. Under the scheme, which is largely modelled on the EU’s emissions trading

scheme, companies will have to hold carbon allowances to cover their own emissions, forcing them to purchase additional emissions if they exceed their cap.

Global water ‘bankruptcy’ A study of almost 200 major international water-related projects over the past 20 years has identified a suite of existing and emerging challenges and how science can offer remedies. “Insufficient and disjointed management of human demands on water and aquatic systems has led to situations where both social and ecological systems are in jeopardy and have even collapsed,” the report notes. River basins in particular are set to experience growing pressures due to urbanization, rising water scarcity and poor water quality. Investing in science, in order to identify emerging issues and track trends relating to the use of water resources, can help to reduce such risks, according to the study. Links between science and policymaking also need to be strengthened.

Sustainable energy futures Experts in energy and finance met to discuss a sustainable energy future at a Climate Week NYC event, which was concluded with a lecture from renowned economist Jeffrey Sachs, where he called for a break in the status quo in US energy policy. “We’ve just had the worst drought in modern history, that has done great damage to the corn crops, and now food prices are soaring. And how many mentions have there been in the presidential campaign? Maybe one.” Sachs said, blaming politicians’ “willful neglect” on “terror at hands of lobbyists.” “We either need to use energy sources that are not fossil fuels. So that could be renewables such as wind, solar, geothermal, nuclear. Or if we use fossil fuels, we need to clean up after ourselves with CCS,” he said. © Aspermont Limited – courtesy WME

Energy and Carbon Data Management Continued focus on greenhouse gas reporting has seen a proliferation in information systems used for organisational greenhouse gas footprints. Ultimately however, an organisation’s ability to accurately identify and reliably capture the raw data can present a greater challenge than any selection of a reporting tool. At a National level, the Clean Energy Regulator’s National Greenhouse and Energy Reporting (NGER) Scheme supports a carbon pricing mechanism. At an organisational level, carbon data management empowers organisations to assess and improve their cost of operation. Carbon systems, with good data planning (identification and capture) can meaningfully expose the relationships between consumption, cost and carbon. Organisations need to start with the fundamentals. Firstly, source data in an electronic format, and in its raw form. This enables processing of larger volumes of data, more frequently, and more consistently. Secondly, get the data regularly. When looking for trends or exceptions, monthly (or even daily) data is far more valuable than annual data. Thirdly, ensure consumption data is identifiable. With a little planning, consumption (electricity, fuel or otherwise) can be tied to specific assets. Finally, ensure the data capture responsibility is “owned” – people are responsible for your accounts receivable, people should be responsible for your carbon data capture.

Leading world in emissions capture CSIRO research scientist Dr Matthew Hill has won the Australian Museum Eureka Prize for Emerging Leader in Science for his work using metal-organic frameworks to capture emissions at worldrecord levels. Gases bond to the MOF’s internal surfaces and one gram of material can absorb a litre of gas, meaning it has the same surface area as a football field. Once trapped, gas can be easily freed from the MOF using only sunlight and turned into products like carbohydrates for stockfeed. “It can wring itself out like a sponge when exposed to light and release as much as 70 per cent of the gas instantly,” Hill said. He recently won a $6 million grant, which he said he would use to take his research “to the next level”. MORE: http://tinyurl.com/9rtfpee

The ZT’s the limit Researchers have developed a thermoelectric material they claim is the best in the world at converting waste heat into electricity, potentially providing a practical way to capture some of the energy that is currently lost. The material, which is based on the common semiconductor telluride, is environmentally stable and is expected to convert 15-20% of waste heat to electricity. The research team, from Northwestern University and Michigan State University, says the material exhibits a thermoelectric figure of merit (ZT) of 2.2, which they claim is the highest reported to date. The higher a material’s ZT, the more efficient it is at converting heat to electricity. While there’s no theoretical upper limit to ZT, no known materials exhibit a ZT higher than three.

Inorganic performs better Ohio’s Bowling Green State University Assistant Professor Mikhail Zamkov and his team have used synthetic nanocrystals to make solar panels more durable as well as capable of producing hydrogen gas. In a video paper published in the Journal of Visualized Experiments, Zamkov outlines the process that involves replacing the organic molecules with two inorganic nanocrystals made from zinc selenide and cadmium sulfide, with a platinum catalyst added. “The main advantage of this technique is that it allows for direct, all inorganic coupling of the light absorber and the catalyst,” Zamkov said. In other words, these are very durable crystals compared to their organic counterparts. Not only are they less susceptible to heat and UV radiation, they also don’t suffer from degradation problems that plague their organic counterparts. MORE: http://tinyurl.com/btqm4pg

Cryogenic system for carbon A team of physicists from the University of Oregon has calculated that by using cryogenics the emissions from coal-fired power plants will result in a reduction of the levels of chemicals entering the atmosphere, including carbon dioxide, by 90%. The team’s paper said CO2 condensed and captured as a solid would then be warmed and compressed into a gas that could be delivered via pipeline at near ambient temperatures to dedicated storage facilities that could be located hundreds of kilometres away. Additionally, other chemicals including sulphur dioxide, some nitrogen oxides and mercury would also be condensed. The team’s calculations show that a cryogenic system would

Knocking out a few genes Scientists at the Massachusetts Institute of Technology have succeeded in genetically altering ralstonia eutropha soil bacteria and were able to convert carbon into isobutanol, an alcohol that can be blended with or even substituted for gasoline. The technology could help reduce reliance on fossil fuels and lessen the amount of CO2 released into the atmosphere by smoke stacks. By “knocking out a few genes, inserting a gene from another organism and tinkering with the expression of other genes”, the MIT researchers were able to get the bacteria to produce isobutanol. Currently, the genetically modified microbes are getting their carbon from fructose. With further alterations they should be able to draw it from industrial CO2 emissions.

Making the most of indoor environments The University of Sydney will encourage architects and builders to create more energy efficient and environmentally sound buildings in Australia with the unveiling of its indoor environment quality laboratory. The IEQ lab will allow architectural and engineering researchers to control and monitor temperature, humidity, air movement, ventilation rates, air quality, daylight, artificial lighting, sound and acoustics. Heading the university’s IEQ lab is Richard de Dear – a worldrenowned expert in the field of indoor climate and air quality. The key aim of the lab is to help industry determine the most efficient way of constructing buildings, cars, trains, buses or planes that are not only more comfortable but are more energy efficient. The facility will also give governments the technical resources to test energy efficiency and indoor quality measurement systems that are embedded into the National Australian Built Environment Rating System.

in perspective Fresh views and clear voices

Striving for sustainable prosperity By 2030, if we keep going the way we are going, we will need two planets. Unfortunately, an extra planet is not available.

I

Chris Riedy is Associate Professor at the Institute for Sustainable Futures – University of Technology, Sydney.

n 2009, a paper in Nature by Johan Rockström and colleagues identified nine planetary boundaries that “must not be transgressed”. They found we are already overstepping three of these boundaries; we are losing biodiversity at an unprecedented rate, interfering dangerously with Earth’s nutrient cycles and changing the climate. At the heart of these three challenges (and many of the others we face) is one central problem – indefinite growth is not possible on a bounded planet. As Paul Gilding points out in his excellent book, The Great Disruption, “the Earth is full”. Indeed, it is overflowing. Growth in the number of people and our material consumption drives demand for land, food, energy and water and creates a whole raft of sustainability challenges. Yet there is very little serious discussion about curbing growth as a response to these challenges. Instead, we pursue endless political negotiations, like those under the Convention of Biological Diversity and United Nations Framework Convention on Climate Change, that deliver change at a glacial pace. There have been some valiant attempts to open up discussion about the sustainability of a growth-based economy in recent years. Gilding’s book is one. He argues that we are headed towards an inevitable series of economic crises that will lead us to measure growth in a new way, based not on quantity of stuff but quality and happiness of life.

‘‘

Our blind faith in our ability to decouple material consumption and ecological impact from economic growth is misplaced

In a similar vein, Tim Jackson’s book Prosperity Without Growth argues that we need to shift focus from pursuit of material economic growth to pursuit of sustainable prosperity. Jackson argues that our blind faith in our ability to decouple material consumption and ecological impact from economic growth is misplaced. He contends that we need a broader concept of prosperity that is more tailored to real human needs. For Jackson, prosperity is our ability to flourish as human beings within the ecological limits of a finite planet. Having more stuff doesn’t help us to flourish and can even get in the way.

What of the post-growth economy?

In the UK, the New Economics Foundation has been working out ways to make the transition from a civilisation based on material economic growth (measured as GDP) to one based on sustainable prosperity with as little disruption as possible. Its report, The Great Transition, sets out a plan for revaluing policymaking to deliver social and environmental value,

redistributing income and wealth, improving local self-sufficiency, developing new skills and redirecting financial institutions. It paints a vision of a prosperous world that grows value, not material use and impact. While the scale of the challenges and responses may seem monumental, there are many tangible things that business and government leaders can do now to point us in the right direction. First, they can help to get a public debate on a postgrowth economy happening. At present, despite the efforts of Gilding, Jackson and others, the mantra of economic growth and unbridled consumption remains largely unquestioned in politics and the media. More voices questioning this status quo and pointing out the inevitable demise of systems based on unconstrained growth can only help. Second, they can support initiatives to give Australians a stronger voice in important policy decisions. To make progress in tackling the challenge of sustainable development we need to genuinely engage people in discussions and decisions about what it is they value and wish to sustain about society. This requires much more than tokenistic “consultation”. There is a great deal of experience around the world now with designing processes in which ordinary citizens, often selected at random, deliberate on important issues of public policy. Such processes have been used for issues like electoral reform, science and technology policy, immigration and climate change. In these processes, participants have shown themselves able to cut through self-interested arguments to make decisions for the public good. Local governments, in particular, should support such processes and businesses should sponsor them. Third, businesses can show leadership by adopting new business models and practices. The need to deliver growing profits for shareholders is a key structural driver for continued resource depletion. More socially aware entrepreneurs are increasingly turning to not-for-profit business models or for-profit models that prioritise a broader range of values than profit maximisation. Using these models to deliver more sustainable products and services, while a partial solution, builds a foundation for a greener economy. Finally, organisations can support more flexible working arrangements for their employees. Ultimately, a society built around sustainable prosperity will be one in which we consume less and need to work less. Supporting employees who wish to work part-time or work from home starts to build the foundations of a culture that strikes a better balance between work and the rest of our lives.

knowledge bank Insights into regulation and compliance

Link to Europe brings carbon certainty Business now has greater certainty to manage its forward carbon liability and, if the international carbon price remains at current levels, reduce compliance costs.

Brendan Bateman specialises in all aspects of environmental, planning and administrative law at Clayton Utz.

T

he Federal government has moved on its promise to link the Australian Carbon Price Mechanism (CPM) and the European Union’s Emissions Trading Scheme (ETS), and other changes to the CPM it announced in late August, with the introduction into parliament of a new package of clean energy bills.

If a liable entity surrenders international units in amounts that exceeds the general or sublimits, the excess will be applied to liability for the following year following a formula set out in the legislation that is intended to ensure that the lowest cost units are surrendered first.

Linking with the ETS

Removal of floor price, addition of reserve

The ETS covers the European Union plus Norway, Iceland and Liechtenstein. It is the world’s largest emissions trading scheme covering approximately 11,000 facilities and with a value in 2011 of $US176 billion. Emissions in the EU fell to 17.5% below 1990 levels in 2011, although the contribution of the ETS to this reduction is questionable given the impact of the global financial crisis and other energy policies such as renewable energy feed in tariffs in some EU members. Linking with the ETS will mean that to the extent Australian liable entities choose to meet some of their liability under the CPM with international units, or the price of carbon units in Australian follows the European price, Australian liable entities will be affected by decisions made by European regulators. In order to facilitate linking with the largest carbon market in the world, the international unit surcharge originally proposed by Australia will be removed by repealing the Clean Energy (International Unit Surcharge) Act.

‘‘

Australian liable entities will be affected by decisions made by European regulators

Whereas a limit on the use of international units was originally a general limit of 50% for the period from July 1, 2015, more detail has been applied, and a sublimit of 12.5% will be applied to eligible Kyoto units (Emissions Reduction Units and Certified Emissions Reductions), so that a liable entity in Australia may discharge its liability by surrendering up to 50% of international units from 2015, and the balance in Australian units, but of the total units surrendered only 12.5% may be Kyoto units. The sublimit will remain in place until 2020. That is, a liable entity could surrender 12.5% Kyoto international units, 37.5% EU allowances, and 50% Australian carbon units. The government may change these designated limits, but must provide three years’ notice of any such change, except where the change is made to facilitate linking to another emissions trading scheme, in which case one year’s notice must be provided. This limitation on amendment is intended to provide certainty and therefore stability to the market.

The rationale for the removal of the auction floor price is to ensure that the cost of carbon units in the CPM reflects the cost of those in the international market. However, proposed amendments to the Clean Energy Act, amending section 111(5), which currently sets out the auction floor price, and inserting a new subsection 111(6A), provide that the minister may by ministerial determination establish a “reserve charge amount” for a specified auction. Explanatory memoranda released with the Bills suggest that a ministerial determination which specifies how the calculation for the reserve charge amount will be made would provide market participants with certainty regarding the method of determining future auction reserve charges. As to the procedural arrangements for the auction process, the minister may establish all the policies and procedures for the auctioning process through a determination. This means that with respect to the actual auction processes market participants still need to wait and see. The number of carbon units from a particular compliance year (or vintage) that may be auctioned prior to that year has been increased from 15 million to 40 million for 2015-16 carbon units auctioned in 2013-14, and 20 million for all advance auctions where the cap for the year of the vintage has not been set. Further, units may not be auctioned more than three years in advance of their vintage year. Equivalent carbon pricing for liquid and gaseous fuels and synthetic gases In recognition of the fact that the use of eligible international emissions units may bring the cost of compliance under the CPM during the flexible price period from July 1, 2015, to an amount per tonne of emissions that is lower than the price of carbon units sold at auction by the Clean Energy Regulator, the calculation of the “equivalent carbon price” will be amended so that: • the price applied to synthetic greenhouse gases and liquid fuels is now known as the “per tonne carbon price equivalent” and is calculated to take into account international links, by using a weighted average of domestic and international units; and • where the calculated “per tonne carbon price equivalent” is higher than the average carbon unit auction price it will be the same as the average carbon unit auction price.

cover story

Transformation more than just good luck

De Bortoli has shifted its environment focus from the vines to the facilities.

De Bortoli Wines is attacking energy and inefficiency on a broad front and with no shortage of ambition. Richard Collins reports.

W

ant to know what real commitment to future-proofing looks like? Let me take you to western New South Wales, where winemaker De Bortoli says it is reengineering for a low carbon future – and to prove it the 90-year-old family firm is aiming to reduce energy intensity by 23% in just a year and nine months. What’s most impressive is the scale and breadth of focus in an initiative it has dubbed ‘Re-engineering Our Future for a Carbon Economy’. It features 10 projects ranging from efficiency improvements to carbon cuts, improved quality to risk and waste minimisation. In June, De Bortoli won a $4.8 million AusIndustry grant that will support a company investment of $11 million on the integrated project. It’s tempting at this point to pigeonhole this as a tale of a company that got lucky with government funding. But that’s too easy. It is a story of good data, good systems and good management, as much as it is about good luck. De Bortoli operations manager and former Foster’s man Rob Glastonbury puts

18

OCTOBER 2012 : WME magazine

a pragmatic spin on it. “If you sit on your hands and do nothing, all you are going to see is rising costs,” he said. “The state we are in at the moment, with the high Australian dollar and rising internal costs, you are going to price yourself out of the market if you don’t do something. “If you are running a business with a 10% margin, every dollar you save in cost is like trying to sell $10 extra of wine.” Wineries are big energy users, in De Bortoli’s case accounting for about 5-7% of its cost base, so it’s a natural target. The key is not just getting aggressive about cost control but imaginative too. We’ll get to the projects shortly, but let’s first look at the background. “De Bortoli, since computers were invented, has always measured,” said environment, health and safety manager Lindsay Gullifer. “We have information on energy usage, utilities, carbon dioxide, things like that, and we have had it forever.” We all know what is supposed to happen to things that get measured. However, © Aspermont Limited – courtesy WME

there is a difference between managing an aspect within trend parameters and actively addressing it. The catalyst for De Bortoli to step up was a 2004 petition from 400 locals demanding it address what Glastonbury conceded were pretty major odour issues. That set the company on a journey that a year later saw it join the NSW government’s Sustainability Advantage program. “What Sustainability Advantage did was give us the incentive to join all those aspects together and look at it as a whole, then start to pick off the low hanging fruit to improve our process,” Gullifer told WME. Fast-forward eight years and De Bortoli submitted something like 25MB of data for the grant under the Clean Technology Food and Foundries Investment Program, blowing the 3MB ceiling applicants had been set. AusIndustry was so impressed that De Bortoli walked away with the biggest grant. Let’s get into the projects.

The power of data

Power factor correction features as low hanging fruit in every energy efficiency list. The company’s Bilbul site has seven transformers with a collective power factor of 0.88; the two at the Yarra Valley site in Victoria are at 0.82. Installing power


factor correction equipment (capacitors) is expected to lift the power factor to 95%. “All the major electrical suppliers had quoted us power factor correction in the order of $250,000 to $300,000 per transformer,” said Glastonbury. “But because we are collecting energy data every 30 minutes, our engineer assembled one year’s worth of the data across the nine transformers and found it did not make sense. “What they were quoting for was like using a sledgehammer for a pin. He issued for re-quotation and suggested using different switching gear would satisfy our requirements. The quotations have all come back between $100,000-150,000 less per transformer – because we had the data.” Each one is expected to save $183,000 a year and pay back in 1.2 years.

In-house design

Understanding the problems, and hence the solutions, also led to the in-house development of what they’ve called SMART pumps, which are designed to stop if pressure or the flow rate drops. “We’ve taken a standard, off the wall pump and developed the smarts behind it. The idea is a bloke can set one up at 3 o’clock in the afternoon before they finish work, dialling in that they want to pump 160,000-180,000 litres overnight. Then if anything happens it shuts itself down and the valves down,” said Gullifer. “When we look at energy efficiency, it gives us the ability to run a centrifugal pump at its most efficient pumping area, where before they might run it on-off or flat out. This allows us to change the way we operate a little.” It was the cellar manager who brought the concept back from an engineering conference, then tinkered around until he came up with what best suited their needs.

A more consistent flow will not only save energy but also increase the life of the filter pads and, apparently, be gentler on the wine, producing greater clarity in the end product. The investment will cut the energy bill by $4000 a year and pay back in just 11 months.

Streamlining production

There are plenty of other tweaks and technology planned for Bilbul, from smart lighting and compressor controls to optimising refrigeration and an improved single stage water filtration system. But the project most critical to the winemaker’s viability is “One Shot Production”, which aims to reduce the number of process steps between storage and packaging from 10 to seven, and eventually to four.

‘‘

There is a difference between managing an aspect within trend parameters and actively addressing it

De Bortoli has been investigating the requirements for six years. One measure it’s ready to roll out is crossflow filtration, which passes the wine parallel to a membrane rather push it through a traditional filter medium, such as earth filters. A big part of the benefit is the system lends itself to “inline stabilisation”, chilling the wine to –2 Celsius to remove sediment in just 30 minutes rather than the current seven days. Cross-flow filters are expected to save $24,000 a year in energy and $120,000 in “consumables” such as filter aid because they will be self-cleaning. The expected payback is 5.3 years, though the deeper business benefit may be in De Bortoli’s

ability to produce and package wine to order rather than in batches. As part of the package it will streamline the bottling plant, including a new bottle warming facility. While intuitively an energy negative, the facility will avoid relabelling up to 1.7 million bottles a year caused by condensation on the glass. That turns out to be a net energy win, even more so when you factor in $70,000 a year in avoided waste costs. Payback: 6.5 years.

Solar cogeneration

The bottle warmer’s high energy consumption created the opportunity to investigate alternative energy. Solar cells did not clear the payback hurdle, but installing a cogenerating solar system on the roof would offset most of the site’s power and hot water requirements, and meet the financial criteria. However, things have changed a little since then. “We’re not quite sure where it will end. We put in a price for air conditioning but since then have found our air conditioners are run on natural gas,” Gullifer said. “We’ve also found a quad-gen system and there was something on my desk this morning about a high-volume evaporative air conditioning system that can also use heat and provide heat in winter. “The quad-gen system provides air conditioning, electricity, hot water and produces fresh water off the evaporators. It has got a payback, it is way past the amount we put in the capital area, but it will be in there for discussion.” Cutting energy use per tonne of grapes crushed by 23% is no small task, but Gullifer’s team of six has divided up the projects. “It is a significant target, but we believe it is possible. We’re wide open about how we achieve the energy efficiency, but we’re all looking for best available technology to get there – and to get above it.”

Getting smart with the numbers Pete Tickler provides an introduction to energy number crunching for greater efficiency and economic gain.

E

nergy efficiency opportunities within properties can loosely be grouped into one of three categories: operational improvements (tuning the building’s existing systems, such as timers and set points); infrastructure improvements (projects to upgrade or improve the building); and occupant behaviour (focusing on how occupants interact with the building). But which of those areas should be tackled first? Even within each group there will most likely be dozens of potential projects a building owner could implement. Before you can make any decisions, you first need to understand how and why your buildings perform as they do. At the foundation of this understanding is data, but it’s much more than that: data has been swilling around buildings for years now, in many cases filling up databases and spreadsheets with numbers that rarely, if ever, get looked at. This understanding shaped the evolution of Greensense, which I founded in WA with Fabian Le Gay Brereton and Derek Gerrard. We started out with a vision of helping companies engage staff to embrace sustainability, with a particular focus on energy and water management in the built environment. Initially bootstrapped through consulting services, it soon became clear what companies needed was a technology platform not simply to provide access to data but as a means to understand and engage with their buildings. We went on to create such a platform and here are some insights we gained along the way.

The data story

There are a couple of parts to the data story. Firstly, you need to acquire good quality, granular and timely data, and secondly you need to turn that data into information that people can understand and act upon. It’s this second part that so many people struggle with. Understanding when, where and why resources are being

consumed, and having that information presented in a simple, actionable and relevant way is key to affecting change. In recent years the audience for building performance data has increased significantly. Whereas traditionally this was often limited to just the facilities manager, or perhaps an energy or environmental manager, we’re now seeing a much larger group of people showing interest.

‘‘

In recent years the audience for building performance data has increased significantly – Pete Tickler, Greensense

This includes finance teams, marketeers and PR folk (both internal and external), HR (think employee retention) and, of course, the staff or students who use the building every day. It’s important to remember though that these groups will have differing interests and levels of technical knowledge, and this must be taken into account when presenting information.

Convergence of systems

Context is integral to helping us understand the performance of our buildings. While an energy profile curve is a valuable tool for identifying efficiency opportunities, it’s not until you introduce some context to © Aspermont Limited – courtesy WME

this data that it really comes alive. Two of the most valuable concepts we commonly include into the dashboards that we design are local weather and occupancy. Why? Because they both have a huge impact on energy and water use. Traditionally, data related to building performance is held within the building itself, normally within the building or energy management system. The problem with this approach is you’re limited with what you can do with that data. Different buildings within a portfolio will often have different management systems in place, which can lead to a timeconsuming and cumbersome process of data extracts and hours of grunt work in Excel to pull together an organisationwide view of building performance. With the advert of cloud-based computing and hosted software platforms many of these barriers can be removed. It’s now possible to store your building data in a secure, cloud-based platform. If you want to view the performance of a particular building, you simple log in using the web-enabled device of you choice, and hey presto! Better still, you can combine that information with other building data from elsewhere in your portfolio to understand the relative performance of your properties.

The last frontier

the last frontier for resource efficiency. While a building may be designed with a swag of great energy and water saving features, ultimately it’s the people who use the building who will determine whether or not it lives up to expectation. In the same way that an older, low-tech building can perform very well if used sympathetically, so a modern, carefully engineered building can fall well short of its performance targets if the occupants don’t play ball. Building occupants are the big unknown. They represent a significant challenge, and a wonderful opportunity, for those of us looking to deliver smarter, sustainable and

• Regardless of the audience, try to ensure your data is as granular and as close to real-time as possible. For example, a monitoring interval of five minutes will clearly highlight an event such as a hot water system cycling. • Add as much context to your consumption data as you can. We recently worked with a client to include data from stair counting software to help students in a university accommodation building understand how, by taking the stairs instead of the lifts, they could help save energy and burn a few calories of their own. • Don’t forget that often the use of one resource is directly or indirectly related to the use of another – think electric pumps and water use – and so where possible ensure you’re collection and display of data tells the whole story. • Keep your metrics as standard, and as uncomplicated as possible. They should be simple enough for everyone in the organisation to understand, while at the same time allowing meaningful comparison between your buildings.

more amenable buildings. Well-educated and engaged building users can contribute very tangible savings – anywhere between 5-25% based on our own observations and those of a number of field studies - as well as less tangible, but equally important, benefits related to areas such as employee attraction and retention. It’s important to think laterally when engaging building occupants. Making feedback and displays engaging, relevant and highly visible, is a good start. We often employ behavioural “nudges” such as fun –

yes, this stuff can be fun - or competition, to help drive engagement, especially for less technically minded audiences. Increasingly, we’re seeing building dashboards being displayed on digital signs around new buildings, providing continuous feedback on performance. Onsite energy generation such as solar PV and trigeneration has also help drive the adoption of energy visualisation software, as building owners look to showcase and communicate these investments to occupants.

energy management systems

Visualising better

business intelligence The presentation of data in a meaningful way has its own unique challenges, write Neil Salisbury and Brendan Lim.

T

he rapid uptake and use of smart meters, supervisory control and data acquisition systems and building management systems, to name a few, has seen organisations faced with an everincreasing challenge of collating and analysing large volumes of energy data. Choosing the data visualisation tools and techniques that best achieve the required outcome is paramount. A recent McKinsey report indicated that, in general, data visualisation lagged its sister disciplines of data capture, data storage, data analysis and knowledge discovery. There is still a huge gap between our ability to extract answers and to present the information in meaningful ways. This is true for energy data, where in most cases data visualisation tools have not gone beyond standard bar graphs, pie charts and line graphs. While these techniques are commonly accepted, organisations need to ask whether their current practices are the best way to represent each individual data requirement.

large databases can offer rapid insight into trends, relationships and distributions. This is especially true in multivariate datasets where simple yet powerful techniques, such as parallel coordinates, Sankey diagrams and tree maps can produce visual data representations that enhance cognition and engage audiences. These perspectives are complementary to more common trending and geographic information system techniques. Figures 1 and 2 demonstrate how datasets spanning thousands or millions of rows can be reduced to relational visuals that provide new forms of business intelligence. Linking traits of location, cooling and lighting systems, energy consumption and cost can be used to quickly confirm “gut feel” and uncover opportunities or outliers where analytical attention can be directed. A treemap technique (figure 1) can immediately review cost or energy intensity in portfolio spanning geography (large segments) and building type (ie the smaller segments). By combining the representation of segment floorspace using New forms of intelligence rectangle size and using an isomorphic The use of visualisation techniques colour range for intensity (akin to a heat to explore energy data is valuable in map) can very quickly direct the viewer to establishing meaning and for directing the location and/or buildings types that are the attention of analysis. We find that consuming most energy per unit of area. the ability to see information hidden in This can inform decisions on expansion strategies or target areas for energy abatement opportunities. Displaying multivariate data as (grouped) parallel coordinates (figure 2) can help users “see” the weight of relationships between variables. Visualising the spread and cooling and lighting technologies in a portfolio of buildings can emphasise a linkage (eg the thick and Figure 1.

to consumption) while discounting the relation of other variables (eg location and lighting type that have dispersed links). Explanatory visuals leverage the output of modelling techniques to communicate technical datasets and insights to decision makers. Often however, the focus of decision making is conditioned to interpretations of economic value and risk. This favours a “best” estimate approach to model outputs that is usually found in tools such as abatement cost curves. However, although these are useful visual decision making tools, they can mask the depth and impact of uncertainty analysis. Being able to see the shape of distribution for future energy costs and their impact on investment metrics can provide a wealth of strategic insight that can inform critical risk management decisions. The use of interactive visualisations that extend the modelling framework provides an additional and valuable layer of business intelligence. Common tools such as Excel can be used to produce interactive visuals and dashboards for sensitivity and scenario testing but can be limiting where larger datatsets or more sophisticated visuals are required. More sophisticated visual tools are, however, not cost prohibitive. The likes of Tableau Public, R and D3 are freely available, data driven visuals that can be rapidly produced and in most cases, linked to both live data and the web. The advances in cloud technologies can further remove barriers to adopting more advanced data visualisation techniques and tools and provide a more collaborative experience.

Urban Energy has emerged as a leading provider of energy services to industry using the most innovative energy technologies available. The range of services and expertise includes: • Reciprocating engine Cogeneration systems • Turbine Cogeneration systems • Waste heat recovery

Show-casing off its smart energy credentials Energy services company Urban Energy has made a name for itself in recent years with several innovative decentralised power projects, and there’s more to come, writes Paula Wallace. The company charged with supplying the new trigeneration system at Sydney Airport, Urban Energy can’t keep up with the demand. The largest project currently on its books, the airport’s two new energy systems will have a capacity of 9.6MW. Their aim is to reduce overall energy consumption and carbon emissions by re-utilising the waste heat from gas

fired generators to provide power site-wide cooling and heating. It’s a model which Urban Energy has been promoting for some time. When tasked with designing, supplying and installing an efficient alternative energy system at Energy Australia’s Learning Centre, it also chose a trigeneration system. The building also has a ground source heat pump cooling system and a large photovoltaic solar array. “This project acted as a showcase for what trigeneration systems can do,” said Urban Energy’s Simon Bennallack, adding that it has become a research piece for the new trainees at Energy Australia.

• Absorption chillers for air conditioning or process chilling • Full design and engineering service

The system was designed to reduce the running costs of the new Learning Centre and is now generating 70% of the electricity base load of the centre as well as creating “free” heating and cooling through waste heat recovery absorption chilling. It’s designed to operate for 15 hours of the day over the peak and shoulder electricity tariff periods.

• Maintenance agreements • 24/365 site and system monitoring and reporting service • Energy production and efficiency reporting • Electrical and thermal energy supply to end consumers

The cogeneration system is a 120kW cogeneration system with a daily electrical output of 1,800 kWh and a daily thermal output of 2,445 kWh. The chiller system is a 98kW absorption chiller with a daily thermal (cooling) output 1,470 kWh.

has reduced the running costs of the centre and saved significant quantities of CO2.” In fact the CO2 output of the centre has been reduced by an estimated 40% and the running costs have dropped by about 35%. The estimated saving of 527 tonnes CO2 per year compared with a purchasing electricity from the grid and buying gas to generate heat, is equivalent to taking 117 cars off the road per year, says Urban Energy.

Urban Energy’s engineers work with clients, their architects and the installing mechanical and electrical contractors on specifications to ensure that the Cogeneration or Trigeneration system selected is fully integrated with the building’s services and operational systems.

Striving for the BASIX When the University of Melbourne wanted to extend is current medical training to include research areas in brain function, mental health and mental health disorders, it wanted to consider the most efficient building technologies which could also help in reducing running costs.

A senior engineer is appointed to each project, responsible for producing and implementing a detailed information package, typically including:

Urban Energy was able to assist the project with energy and waste heat recovery solutions which also enabled the $161 million Parkville Neuroscience Facility to achieve its desired 5 star BASIX rating. The new facility aims to be one of the most sustainable research institutes in Australia by installing a range of ecologically sensitive equipment. The cogeneration system is operating as one of the many technological energy and water saving features of the new building including an extensive photovoltaic array and efficient HVAC system. The system utilises a sophisticated cogeneration system complete waste heat recovery system to efficiently generate a proportion of the electricity and efficiently generate heating for the new facility. This system is designed to operate for 24 hours of the day in an island connection to operate the mechanical services of the building. It will provide a peak electrical output 120kW, which

DSP to change energy landscape The right environment for demand side participation may be upon us and now comes the challenge of matching the right technologies. By Daniel Brass and Nick Bamford.

T

o date, DSP has had only limited success but on the back of high energy prices there is a new-found desire to make DSP work and the Australian Energy Market Commission’s recent Power of Choice review could provide the basis for substantial reforms. This, combined with developments in building scale energy management technology, is a reason to reevaluate their commercial viability.

Storing it makes sense

Thermal energy storage refers to a number of technologies that store energy in a thermal reservoir for later re-use. They can be employed to balance energy demand between day time and night time, or even different seasons. The thermal reservoir may be for either heating hot water storage or chilled water storage. For the purposes of DSP, low temperature storage via chilled water, ice storage or phase change materials are commonly utilised for their ability to offset electrical demand to operate chilled water plants. Thermal energy storage for low temperature applications, in addition to reducing peak demand, can be used to take advantage of lower night time ambient temperatures which increase chiller operating efficiency and lower night time electrical tariffs. It is important to note that chilled water storage tanks are significantly larger than high temperature thermal stores as the difference in flow and return temperatures is often less than 15C. Ice storage, which uses the latent energy of phase transition, significantly reduces the storage size required for chilled water. However, additional infrastructure and running costs are required to generate water at less than 0C. Brine or glycol loops are required to reticulate water at less than 0C which reduces the operational efficiency of chilled water plant. Phase change materials are sometimes used to reduce the size of chilled or heating hot water storage tanks yet economic

feasibility can often be limited by the cost and lifespan of the material. Currently, there are no specific planning or legislative restrictions in the use of thermal energy storage.

FACT FILE: Advantages of thermal energy storage • Ability to reduce peak electrical demands • Increased running efficiency of the existing plant • Increased utilisation of waste heat or cooling • Reduced operating costs of the existing plant • Redundancy in storage to mitigate plant failure or maintenance

Cogeneration – more than a buzz word

Cogeneration, also known as combined heat and power, is the process of producing electricity by combusting fuel and using the waste thermal energy of the combustion process for heating purposes. Waste thermal energy can also be used to produce chilled water with the addition of an absorption chiller. When power generation is combined with the production of heating hot water and chilled water, the generation scheme is called trigeneration. As well as reducing peak demand by moving electrical energy consumption to gas consumption, cogeneration and trigeneration systems increase the use of energy released through the combustion process, thus improving overall energy efficiency. Although natural gas is most commonly utilised in cogeneration due to its availability and low carbon content, it is also possible to generate electricity via biogas, diesel, biodiesel, oil or syngas (coal gas). As there are multiple products of a cogeneration/trigeneration plant, the plant is generally configured to run under electrical or thermal lead. For instance, in © Aspermont Limited – courtesy WME

Daniel Brass – AECOM.

electrical lead, the generator is set up to modulate electrical output on electrical demand. Heat or thermal energy in this instance becomes the waste product to be used or rejected via cooling towers. Natural gas generators significantly reduce in electrical efficiency at part load. So generators are selected for the electrical and thermal building/precinct demands to ensure part load operation is minimised. Load modelling of the building/precinct is recommended to ensure generator selection is optimised for the electrical and thermal demands of the building or precinct.

Off-the-shelf

New building-scale energy management technologies are clearly capable of shifting at least some of our network and market demand peaks. However, without clear commercial incentives, these technologies are unlikely to feature in many new building designs. Currently there are a range of offthe-shelf or negotiated agreements between customers and electricity distribution companies or customers and energy retailers, for the reduction in peak demand. Common incentives that are currently available include: • Time of use – TOU or peak/off peak WME magazine : OCTOBER 2012

Ability to reduce peak electrical demands Reductions in utility costs Reductions in greenhouse gas emissions Ability to provide backup power via onsite generation

Design factors that can affect feasibility: • A cogeneration plant has a large spatial requirement that can complicate finding a suitable location for plant, specifically in an area already developed • Large upfront infrastructure and running costs often decrease economic feasibility • Large baseload utility demand is often required to optimise plant utilisation Electricity providers are often reluctant to connect a generation plant to their existing electrical infrastructure. In particular, the Melbourne CBD has an antiquated electrical infrastructure that is not designed to deal with the fault currents that can be imposed by onsite electricity generation plants.

tariffs are already fairly common but their use for the network component of residential tariffs is currently restricted; • Critical peak pricing – depending on their location, large customers (companies large enough to negotiate their tariffs) may be able to opt for CPP network tariffs which typically add a very high tariff on designated network peak days in return for a lower everyday A S C and E1 2 T r a d e Ad 6 . p d f Pa tariff;

• Negotiated demand management – customers can also negotiate to provide DSP to their retailer. Anecdotally, this results in a 50:50 split of any profits the retailer can make by curtailing demand. However, it is typically only available to very large customers.

For the benefit of all

electricity users In the wake of a draft report from the energy market rule maker, it’s now likely electricity users will, to some extent, be able to participate in the wholesale market in eastern Australia, writes Ross Fraser.

T

he Australian Electricity Market Commission’s (AEMC) draft Power of Choice Report has the potential to reduce wholesale market price peaks to the benefit of all electricity consumers. Specifically, it recommends large commercial electricity users be paid to reduce their demand in competition with generators during peak periods. Such events only occur for a few hours each year, but without demand response the only way to keep the lights on has been to build expensive generators to cover these short and infrequent events. The AEMC’s recommended change will help overcome an issue that has plagued the National Electricity Market (NEM) for the past 14 years. It will improve value to all electricity users through greater financial efficiency in line with the National Electricity Objective. However, the recommendations proposed for electricity network

regulations are both weak and of little value to electricity users. The major issue in current regulatory processes is that they motivate the augmentation of electricity networks to meet occasional peaks in demand. Instead, regulations should motivate the network businesses to use DR when these occasional peaks occur. A recent report by Carbon Market Economics director Bruce Mountain analysed the past 10 years of NEM electricity cost data. The report found that had the NEM rules enabled the use of demand reduction to manage the highest 100 hours of peaks in demand instead of building network and generation capacity to meet those peaks, $15.8 billion could have been saved. The active participation of electricity users in electricity markets and networks is well proven in the United States, Canada, the UK, parts of Europe, New Zealand and Western Australia.

fact file: Townsville’s pathway towards DM When Ergon Energy arrived in Townsville to begin their Townsville Network Demand Management pilot project, they had three things in mind – cutting costs, cutting energy and cutting peak demand. To achieve all three objectives, Ergon Energy got a group of engineering and energy solutions experts to focus on the issue of how energy conservation and demand management could assist Ergon Energy’s Network business continue to meet customer demand for supply within the constraints of the Australian Energy Regulator (AER) framework and current economic environment. The Townsville pilot project proposed entering into contractual arrangements with a number of commercial, industrial and institutional electricity users in the Townsville region. The idea was to use different Network Demand Management technical solutions and commercial delivery models to prove the viability of various types of arrangements. Ergon Energy’s development manager large customer energy conservation & demand management, Warren Applegate, began working behind the meter with the customer to gain an in-depth understanding of the customer’s energy needs to influence the shape of their energy curve for the benefit of the network, the customer and the environment. “In Townsville, Ergon have commitments from a large range of commercial and industrial customers to reduce demand by 20MVA by 2015, which is expected to save infrastructure investment of around $72 million,” Applegate told WME. “In all the projects done to date we have achieved an average of 30% energy savings for the customer, for an average three year payback on capital they invest,” he said.

It is far more cost-effective to pay participating users to reduce some of their demand (without any harm to their operations) rather than continue to make very inefficient capital investments. Very large electricity users may be able to participate on their own behalf, although most commercial and industrial businesses prefer to contract their demand reduction capacity through a third party called a demand response aggregator. These aggregators have specialised tools and systems to maximise the value and remove any risk to the participating user. Charged with a brief to address increased electricity prices, a Senate select committee with broad terms of reference, has also been established. The most obvious concern for users would be the trend of falling electrical energy consumption from the grid over the past five years and the simultaneous increase in the price of supply, due to the cost of the infrastructure being built. One of the most important outcomes we need from both the Power of Choice Review and the select committee’s work is for policies to address these peaks that will ensure a much more financially efficient market and network supply and hence considerably lower costs for all consumers.

An innovative Australian story At this year’s Green Globe Awards, Local Government Super took out two of the key prizes, confirming its place as a sustainability leader. By Paula Wallace.

T

he Climate Change Leadership and Energy Awards from this year’s Green Globes can be added to New South Walesbased Local Government Super’s swag of acknowledgements over the past year. LGS has demonstrated leadership in sustainability and responsible investment with more than $A3 billion in green investments, by far the largest of any Australian super fund. LGS can claim enviable sustainability performance across its $500 million property portfolio. Last year, it reduced energy consumption by 14.5% and water

consumption by 5.3% across its commercial portfolio. Within its retail portfolio, energy consumption was reduced by 7.7% and water consumption by 8.8%. LGS is also leading the industry in the greening of older office buildings in Australia in a way that has the potential to revolutionise how owners and managers retrofit their buildings. Its flagship commercial property at 76 Berry Street, North Sydney, was recently retrofitted and is now considered to be the lowest emission office building in Australia.

Energy innovation

At the heart of the $6 million upgrade at Berry Street is a state-of-the-art gaspowered trigeneration system that simultaneously generates electricity, heating and cooling using Australian-made Bennett Clayton engine technology. The building comprises two levels of basement parking, lobby and retail areas, including a coffee shop, restaurant and landscaped gardens and 10 levels (11,000sq.m) of office space. The aim of the project was to reduce the heat load through a whole-of-building lighting upgrade, replace the existing heating, ventilation, and air-conditioning system in the plant room with the most efficient system available. It also aimed to improve working conditions and reduce emissions.

For the trigeneration system, the project team sought out the most efficient system with the flexibility for running low and high loads. The chosen system will allow the building to operate without the need to take power from the electricity grid, which will now act as a backup supply for the building. The unique 5x100kW engine system for trigeneration has the ability to deliver small generation systems to commercial buildings where load profiles previously would not support the operation of these types of systems. The engines are multi-fuel capable, so if bio-ethanol or bio-methanol becomes an available fuel source for the building it can convert to these in the future. As a result, the building’s emissions have been reduced by about 85% and it is expected to operate 100% independently of the electricity grid within a year. Additional to the emission benefits, the reduction in pollutants, as noted in independent testing, provides improved air quality which has the potential to offer a range of environmental and associated health and social benefits for

those living and working near the building and the wider community. In 2010, the project was recognised by the federal government’s Green Building Fund as an exemplar project and received a $2.1 million grant towards the refurbishment. Walker EcoStrategies director and project director of 76 Berry Street Roger Walker said the grant allowed LGS to take a more ambitious green position with regards to the technologies used in the refurbishment. “As this was the first time that the lean burn low environment impact Bennett Clayton engines have been used in a trigeneration plant, the funding essentially enabled us to take that risk,” Walker said. With five office building upgrades in NSW already under its belt, LGS has used the experience to adapt tried and tested energy efficient technologies at its North Sydney property. The most energy-efficient building in Sydney – the group’s 120 Sussex Street – led by example. The same E1 Lighting, manufactured in southwest Sydney, and PowerPax chillers, manufactured in Melbourne, have been installed in 76 Berry Street.

While green buildings might be considered a bit sexy, the positive energy building has the definite X-Factor, writes Paula Wallace.

hat better way to embody your “green” values as an organisation and demonstrate what trailblazing environmental services you can offer to industry than by creating your own building revolution. That’s what Dave Collins and the team from Synergetics Environmental Engineering have managed to achieve in Melbourne, with a showcase building due to be unveiled in October. Recently renamed Positive Energy Places, the metamorphosis of the building at 490 Spencer Street (which began life in the late 1980s as a two-level 400sq.m commercial office building) is obvious and the ongoing performance will be plain for all to see. What the Synergetics team started with was a simple concrete tilt slab construction with a steel deck roof, concrete walls and large single pane plate glass windows facing east, west and south. What they have created is a light and inviting office space that is warm in winter and cool in summer, which has achieved beyond carbon neutral energy performance. An analysis of the Positive Energy Places building by students at Monash University’s Faculty of Engineering determined that on average, the commercial office building at 490 Spencer St, Melbourne, generates 121% of its energy requirements. “We decided to apply our deep technical skills to the environmental challenges and show that beyond carbon neutrality could

be achieved easily and without massive financial outlay,” Collins said, issuing the challenge to businesses big and small to join the positive energy movement. Computer modelling enabled Synergetics to target energy saving initiatives and minimise costs. The retrofit was carried out opportunistically and the sustainability requirement drove every decision. Old ceiling tiles were given away for reuse rather than being landfilled, for instance.

Reducing energy consumption is not enough – Dave Collins, Synergetics

“Reducing energy consumption is not enough. An important initiative is to maximise the generation capacity as shown by the 23.6 kilowatt solar panel array covering the entire roof of the building, except for a small wooden decking,” Collins said. Two independent high accuracy energy monitoring systems, each measuring all building circuits, were installed on the power boards to allow continuous verification of the measured data.

fact file: The green ‘link’ The disused laneway adjacent to Positive Energy Places has been transformed by Synergetics staff into a green space with a wide variety of plants using recycled wood as planter boxes providing many benefits. It sequesters carbon and generates oxygen; provides attractive breakout spaces for eating and meetings; is a great place for summer BBQs and networking; provides a green oasis in a sea of concrete slab buildings and traffic; and it looks great. Synergetics is working in partnership with its neighbours and the City of Melbourne to apply artwork to the building façade.

Synergetics is developing accessible software for display of “carbon abatement curves” and is in the process of patenting an energy scavenging system to more effectively utilise outside air and air from other parts of the building. Positive Energy Places has established another Australian first for green office buildings, whereby all energy consumption and generation data is made publicly available in real-time at www. thegreenspaces.com.au, using software developed by Synergetics (to be migrated to a new website – www.positiveenergyplaces. com.au – in October). “Another X-Factor is the participation of tenants to guide the retrofit process. Even while the fit-out was still underway, every desk was occupied,” Collins said. “Tenants were enthused by the idea of participating in the process with much of the work having to be completed only on weekends to satisfy OHS requirements.” No expensive technologies were used. Almost everything done to the building can be purchased through local suppliers or online, further emphasising how easy it is for other businesses to change if they want to make a difference or simply add value to their existing service or product. Exceptional natural light, as well as presence sensors, timed switches and zoned lighting using energy efficient LED and T5 light fittings were installed. Furniture, workstations and carpet, as well as glass and doors where possible, are all second-hand, realising an embodied energy saving. High R-value insulation has been installed in the ceiling and 5 star toilets saving 2.6 litres per flush were incorporated into the fitout.

The added power of integration To be competitive, companies, particularly in process industries, must work as a collaborative team and this means access to the same real time data across plant systems, writes Thoralf Schulz.

P

roviding an integrated framework of systems and applications in which all actionable information is available for use in the system, ABB has just released the upgraded version of its Extended Automation System 800xA. Release 5.1 includes enhancements to help ABB customers improve performance, usability and operator effectiveness with a substantially reduced system footprint. The system extends the reach of traditional automation systems beyond process control with an aim towards achieving the productivity gains being demanded by industry. System 800xA has the capability to integrate automation and information management systems in a single plant. It can also link the systems of plants at different sites, and in different countries, into a single, integrated entity.

Extended automation

First released in 2004, System 800xA was designed from the outset to function as an integration platform with connectivity to enterprise and plant systems, applications and devices where real-time decisionmaking was a reality. It was developed with the aim of promoting collaboration through integrating diverse, usually separate plant systems, applications, information or fieldbus and controller platforms. Not only has System 800xA been widely embraced for new projects, but it is also the evolution path for ABB’s traditional control systems. More than 6000 units have been sold to extend automation functionality in a wide variety of industries, including oil, gas and petrochemical; pulp and paper; biotech/ pharmaceutical; utility; chemical/fine chemical; metals; and mining. System 800xA extends the reach of a traditional distributed control system (DCS) to incorporate process control, production management, safety, discrete logic and sequence control, advanced

control, information management, smart instrumentation, smart drives and motor control centres (MCCs), asset management, and documentation management capabilities into a single virtual database environment. It does this through the use of a unique Microsoft Windows-based operating environment that enables presentation of information, in context, to the right person in the right format from any point within the system.

What’s new in System 800xA

With this latest release the power of integration is strengthened with the aim of delivering improved functionality that promotes collaboration, improves operator effectiveness, generates cost-effective solutions, helps achieve seamless control and provides flexible evolution paths. For example, Version 5.1 is a Microsoft Windows 7-based release resulting in an improved life cycle for ABB customers and for future developments. The latest version is able to accommodate 120,000 objects and supports larger applications, making it easier to integrate multiple systems. Version 5.1 is online upgradeable from the latest version of 5.0; a running system can be upgraded on the fly without interrupting production (for System 800xA 5.0SP2 installations). ABB’s engineers have added to and enhanced System 800xA’s portfolio of communication interfaces to help users further leverage its powerful integration capabilities. These include new communication interfaces for PROFINET, DeviceNet via Ethernet IP, and WirelessHART. System 800xA Release 5.1 improves life cycle management through the use of the latest technology, providing more performance and usability through increased system sizing and a more powerful controller, increased energy savings, reduced maintenance costs © Aspermont Limited – courtesy WME

through footprint reduction, and improved operator effectiveness through integrated information and alarm management.

Local benefits

ABB’s 800xA Extended Automation System has enabled Australian Paper (AP) to expand, modernise and centralise the plant automation system at its Maryvale site in the Latrobe Valley, Victoria, an essential part of the pulp mill upgrade and bleach plant project. The 800xA system has provided seamless integration of the different control systems previously implemented on the site. It connected variable speed drives, motor control units, turbine governors and instruments. This allowed real-time integrated data to be made available for process and maintenance optimisation. The first major shutdown for the pulp mill upgrade was completed on time and carried out without any unscheduled delays. According to AP executive general manager Jim Henneberry: “For Maryvale and AP the DCS work was the highlight of the June shutdown.” To deliver this complex project for AP, ABB worked with its local service team in the Latrobe Valley and was backed up by specialised industry resources in Melbourne and at the ABB Pulp and Paper Centre of Excellence in Singapore.

See your footprint

from all angles Using a new web-based tool developed by iota, Australian companies are able to measure, store, retrieve and analyse data on a wide range of key inputs and outputs. By Paula Wallace.

F

ootprint, developed by iota, an arm of Melbourne water retailer South East Water, is able to track information related to energy and water consumption, stormwater, trade waste discharge and waste to landfill. It has helped a number of organisations across Australia gain insight into sustainability data and how it can assist in achieving business goals and improving efficiencies. For instance, the City of Greater Dandenong installed consumption metering on 18 meters which has enabled it to reduce electricity consumption costs at various sites by determining which sites have not been turning off lights at the appropriate times and by identifying sites and functions, such as heating and cooling, that were not operating correctly. The tool has also enabled the council to properly monitor IT server upgrades to determine power usage saved and to confirm via the monitoring system that installation of Flurosave units to an office site was saving 175,000 kilowatt hours per annum.

Making dramatic savings

PPG Australia detected water wastage, reduced its water consumption through the use of Footprint and saved more than $35,000. The large paint and coatings company used the tool to generate reports on the history of water use at its site. It produced a water balance enabling the

company to identify the unaccounted base flow and other production spikes. Through Footprint, PPG quickly discovered some urgent operational issues onsite, namely tanks were overfilling and jacking pumps were turning on when not required. By pinpointing the issues quickly, the company rapidly rectified the problem and achieved an immediate reduction in daily water consumption from 133.8 kilolitres to 75.4kL, saving thousands of dollars on its water bills over the next financial year.

“Footprint helped PPG obtain a comprehensive picture of performance in real-time across the organisation,” iota services manager Jean-Paul Lambe said. “Having access to quality data didn’t just help PPG monitor and report on its environmental performance, it gave the company an opportunity to actually repair the problem and reduce its water consumption.”

PPG was able to see improvements within a month. It now uses Footprint to continuously monitor its results. It has set alarms to notify the PPG team of any further ongoing issues and any possible savings it could make in water and trade waste costs.

Uncovering major water leaks

Unidrive, an Australian manufacturer of driveshafts for the automotive industry, used Footprint to identify wastage, implement corrective action plans and reduce costs. Unidrive uncovered some surprises with Footprint and found its detailed report format to be beneficial. It initially discovered 45kL of water was lost due to a hose in a die wash bay falling and knocking its valve into the “on” position. The company then detected further losses due to a toilet cistern leak and hand basin taps left running, as well as an incident where water was syphoned from a cooling tower when it was shut down. By closely monitoring its water use, Unidrive discovered water consumption rates of between 360-470 litres on Sundays – shut-down days – providing clear evidence of a leak. By using real-time monitoring, Unidrive was able to detect the water leaks, fix faulty equipment immediately and change its practices. “It’s like having another set of eyes on operations. It’s real-time information at the user’s fingertips and it’s very easy to use,” Footprint product manager Greg Boxshall said. For more information, visit iota.net.au

spills + safety equipment

Bringing soil pollution into focus OTEK is the first Australian company to successfully combine two contaminated land assessment technologies to produce groundbreaking results for the environmental sector.

T

he combination of direct sensing tools and an En Core sampler have significantly increased the reliability of analytical results and enabled contamination data to be processed in real time, making the process considerably faster than previous approaches. The major benefit for organisations which own, or are looking to purchase, potentially contaminated land is the ability to reliably gauge the return on investment for a project; these tools provide a greater level of certainty about the clean-up activity that will be required. These new tools provide companies with extremely reliable information that enables them to have a more holistic view when making financial projections for land purchase, land sale, litigation or remediation activities. This is particularly important when developing industrial or contaminated land, especially for residential developments and resource sector projects. The costs of using these new technologies is lower than traditional methods and provides greater long-term benefits by avoiding surprises and unplanned work. OTEK chief technical officer Glenn Thiele said: “Being the first company in Australia to offer the full range of tools and rapid interpretations, OTEK is already providing clients with greatly improved decision-making capabilities. “The difference between this advanced technology and traditional approaches is like looking at an extremely highresolution photo and a low-resolution pixelated image. The comparison is like night and day.”

Details on leaks

The direct sensing tools used by OTEK include a soil conductivity/membrane interface probe, a ultraviolet optical screening tool and a hydraulic profiling tool. With the help of the professional

team at South Western Drilling, the tools are pushed into the ground where they collect detailed information on chemicals that have leaked into the land. The data collected is then analysed by a sophisticated computer and interpreted by OTEK consultants to deliver a rapid and accurate picture of contamination. The typical techniques currently used in Australia provide only 25–100 data points to analyse per day, whereas this new technology results in 9000–18,000 data points, greatly increasing the reliability of results. The first use of this technology in Australia was for an OTEK client who was planning to redevelop a 6 hectare property from industrial use to residential land use. A large-scale and expensive contamination clean-up project on an adjoining property caused the client concern about the amount of money they might need to spend in resolving contamination issues as part of their property redevelopment project. With this in mind, the client posed two questions to the environmental and engineering services firm: 1) Has contamination from the adjacent property spread onto our property? 2) Does the property we plan to redevelop have contamination problems © Aspermont Limited – courtesy WME

severe enough to significantly reduce the return on our investment? In this case, the contamination of concern was industrial solvents which were commonly used in Melbourne after World War II and could be expensive to clean-up. To answer the client’s questions, OTEK chose to use a direct sensing tool called the soil conductivity/membrane interface probe which is the state-of-the-art equipment for defining solvent, methane, and petrol contamination in the subsurface. Using these new tools is only part of the story. The set up and analysis is extremely important to ensure the most accurate and reliable results. OTEK consultant Roger Lamb is one of the world’s foremost experts, having spent 18 years using similar direct sensing tools, and is a pioneer in using the data to calculate remediation costs. After collecting 12,700 pieces of data with the direct sensing tool in just one-anda-half days, OTEK was able to confidently answer the client’s questions. This enabled them to move forward with far greater certainty on the extent of contamination and how much it would cost to clean up. For more information, contact OTEK on (03) 9095 1900.

spills & safety equipment

Protecting

waterways from spills Incredibly simple in design and function, Pollu-Plugs are an effective way to prevent accident contamination caused by spills into water and sewerage lines.

T

he range of Pollu-Plugs made by global elastomer specialist Pronal are permanently and unobtrusively fitted in water and sewerage lines ready for instantaneous inflation by remote triggering as soon as an emergency arises in industrial, civil and municipal applications. Available from Air Springs Supply in Australia, Pollu-Plugs can be triggered by an urgent need to contain a toxic fluid spill or to prevent the spreading of firefighting or contaminated process water into a pipeline and into the environment downstream. When pipelines are not subject to an emergency, the uninflated stopper allows normal non-polluted content to pass beneath the elastomer-coated Pollu-Plug, which is located flat inside the top of a pipeline. It is connected by an air supply line to an all-weather control panel and nitrogen inflation cylinder supplied by the customer and located outside the pipe. Pollu-Plugs are available in diameters of 100-1000mm and lengths of 450-2050mm (both measurements when empty), and can be custom-made on request. “The beauty of this product is its absolute simplicity, efficiency and near total lack of maintenance,” said Air Springs Supply national sales and marketing manager James Maslin. Inflated at pressures of between 40120kPa, depending on pipeline diameter, they complement Pronal’s extensive range of OFR anti-pollution stoppers designed for maximum sealing diameters of 7702115mm.

A fraction of the cost

Visy Beverage at Smithfield, Sydney, has installed a Pronal anti-pollution stopper as a precaution against industrial waste seeping into a stormwater drain passing through its production site. The rugged 1170mm diameter plug,

which is integral to Visy’s broader environmental policy, was custom-made by Pronal. “What appealed to us was their simplicity. They are easy to install and the deflated stopper is designed to allow normal non-polluted effluents or water to pass through the pipe when the stopper is uninflated. It helped too that they were a fraction of the price of the gate valve that we were looking at as an alternative,” said Visy project engineer Craig Tomison.

‘‘

Pollu-Plugs can be triggered by an urgent need to contain a toxic fluid spill or to prevent the spreading of firefighting or contaminated process water

The custom-made plug, which can be inflated in minutes, is used by Visy to prevent accidental spills from trucks or holding tanks that could ultimately pass from the drain into nearby creeks leading to wetlands in parks and heritage areas. The plug has been tested to be effective against water-borne spills of common industrial and packaging substances such as solvents, inks, acids and other aggressive materials. With an overall length of 1.64m and an effective sealing length of 1300mm, the plug is positioned within the pipe on a central steel axis located by a permanent frame. “We have the inflation feed to the © Aspermont Limited – courtesy WME

plug permanently linked into our factory pneumatic system via a low-pressure regulator. This arrangement, housed within the production site, is very simple to actuate for scheduled testing and for actual emergency conditions,” said Tomison. In addition to the actuation method chosen by Visy, the stoppers can be connected by a gas supply line to an allweather control panel located nearby, above ground. When an emergency arises, the OFR stoppers are triggered either by a manual striker or an optional electrovalvepiloted control unit. Air Springs Supply general manager Simon Agar said: “Inflation can be provided in minutes by the gas cylinder method (typically using nitrogen) or alternatively by connection to pneumatic systems adapted to provide the low maximum inflation pressures in the pipe, which range from 0.20.5 bar, depending on the pipe diameter”. Protected by a polyethylene cover to counteract effluent aggression, the extensive range of OFR stoppers are designed primarily for use with retaining pits, but have also been successfully employed to protect natural waterways from industrial spills. “As part of their risk management strategies, major industrial plants have employed them in pipelines leading to creeks and ponds that could be devastated by spills of chemicals and waste,” said Agar.

Container policy

debate rolls on At the meeting of Australia’s environment ministers in August, the decision was made to undertake more detailed analysis of options for dealing with packaging waste, writes Paula Wallace.

Drink containers account for 12 billion of the containers disposed of each year.

W

hile Australia’s environment ministers have agreed to broaden the scope of the decision regulatory impact statement to include options put forward by container deposit scheme (CDS) advocates and industry, the Greens have failed in a bid to introduce a national scheme. Greens senator Larissa Waters said a national scheme was needed to address the litter from 12 billion drink containers that Australians used every year. “It seeks to practically address that only about half of them are recycled, where most of the remainder end up as litter or in landfill,” she told Parliament. South Australia has had a scheme since 1977 in which people get a cash refund for returning used plastic bottles and cans and the Northern Territory introduced a similar scheme in January. But Labor and coalition senators joined forces to strike down the Environment Protection (Beverage Container Deposit and Recovery Scheme) Bill 2010. Labor Senator Anne Urquhart earlier said the plan did not respect the cooperative work done by governments and industry to reduce packaging waste and litter. “It is a heavy-handed national approach that seeks to undo the good work done at the [Council of Australian Governments] table,” she said.

Environment ministers from federal, state and territory governments met on August 24 at COAG, where they agreed to undertake a more detailed analysis including regional and distributional impacts. However, Queensland has decided not to participate in any further CDS negotiations, rather opting to roll out a bin network across the state. The additions to the decision RIS will include: • an industry co-regulatory stewardship scheme focusing on beverage containers only; • an approach similar to the Australian Packaging Covenant, with a substantial increase in industry funding for initiatives; and • a container deposit model based on the SA system. Another option that had been considered in the lead up to the COAG meeting, where industry would pay for all of the costs of beverage container recycling (option 2d – extended beverage container stewardship), has now been removed. Boomerang Alliance national convenor Jeff Angel welcomed the news. “Now we are moving to the last stage of the decision making process, the full benefits of a CDS will become apparent,” Angel said. © Aspermont Limited – courtesy WME

“The decision RIS can now focus on the real world financial benefits.” MS2 consultant Russ Martin said: “The fact that Queensland has already split off means that if one other state decides that CDS isn’t a good idea it could be blocked. “We have not necessarily moved any closer to a national CDS, what we are seeing is the next step of a more deliberative process that fleshes the options from the consultation RIS out in more detail,” he said, adding that a decision RIS provided another year to consider the options. Both the Australian Food & Grocery Council and the Australian Beverages Council expressed their disappointment, referring to CDS as a tax on families and said such a move could lead to job losses and reduction in consumer choice. “The industry is already in a state of contraction and any further stress on manufacturers, including small and medium companies, through a drink container tax will cost jobs,” Australian Beverages Council chief executive officer Geoff Parker said. “Secondly, it is estimated the drink container tax will add an additional $300 to the annual shop for households at a time when they’re doing it tough. “Finally, the impact on the industry of a drink container tax will force many small and medium-sized companies, particularly those in regional towns, to scale down or worse still, close. Consumer choice will be greatly diminished.” Martin said: “As we move down a decision RIS process I would like to see industry lay out more viable alternatives and provide more details. If they don’t, they will definitely get stuck with CDS. “If they have a better alternative they need to effectively convey that and build support, with public discussion. I think industry has not been proactive enough in making the case that there are alternatives available that could be better.” The plan currently being put forward by industry, the National Bin Network, includes installation of more than 30,000 bins over five years, collecting around 50,000 tonnes of packaging recyclables each year. It would also “coordinate the systematic placement of recycling infrastructure in regional and metropolitan locations”. WME magazine : OCTOBER 2012

waste + resources Understanding the composition of waste streams can lead to lower carbon liabilities.

How well do you know your waste? As landfillers and big waste generators come to grips with the Carbon Pricing Mechanism they are finding new opportunities for cost savings, writes Oliver Bradshaw.

T

he introduction of the Carbon Pricing Mechanism (CPM) has provided added incentive for landfillers and big waste generators to move on from using default National Greenhouse and Energy Reporting System (NGERS) values in determining their carbon liabilities. As such, these groups are now also starting to see the benefits. In a new wave of carbon understanding since the implementation of the CPM, many landfillers and waste generators are beginning to understand that low organic wastes mean lower carbon liabilities, regardless of the waste stream they fit into. The use of default Waste Emissions Factors (WEFs) - 1.19 for Municipal Solid Waste (MSW), 1.08 for Commercial and Industrial (C&I) and 0.17 for Construction and Demolition (C&D) wastes - were a great way to initially assess liabilities and determine the carbon costs of landfilling waste. However, the industry is now moving beyond the basics and looking to implement new and refined ways of assessing their liabilities and working out what this means for their costs. One such approach at looking for

38

OCTOBER 2012 : WME magazine

emissions reductions has come through the refinement of WEFs. The WEFs tell us what the entire embodied carbon emissions are for a particular waste under NGERS. The WEF for any given waste stream is entirely driven by the composition of the waste in question. So if you change or have a waste composition which is different to the NGERS defaults, then you’re WEF and your carbon liability is also different to the NGERS defaults.

‘‘

Many landfillers and waste generators are coming to understand that low organic wastes mean lower carbon liabilities, regardless of the waste stream they fit into

In practice, we have seen a C&I waste stream with a WEF of 0.13 instead of the NGERS default 1.08 and an MSW stream with a WEF of 0.90 instead of the default 1.19. Each of these changes were shown by a waste generator looking at an individual © Aspermont Limited – courtesy WME

waste stream and a landfill looking at their entire MSW waste profile respectively. In real terms, these changes in WEF provided an 88% and 25% reduction in direct carbon costs for these parties, respectively.

Working together

Major waste generators and landfill companies are now working together to turn this new understanding of WEF refinements into reality. Luke Parker from Sell & Parker Metal Recycling Services in Sydney’s west is currently looking at how the WEF of his flock waste can reduce the overall carbon costs for both him and the landfill which receives his flock waste. “As flock waste is very low in organics content, we felt that something needed to be done to better reflect this in the costs and emissions liabilities our waste incurs,” he said. The flock waste from Sell & Parker’s facility has a WEF of 0.13, lower than the NGERS default emissions factor of C&D waste, the lowest default WEF currently available. This reduction in carbon liability is solely driven by the very low organics content in the waste stream, in fact, less than 6% of the entire waste stream is organic. While this new approach to determining emissions liability has caused a number of headaches for the landfill sector, the sector is also very positive about this


fact file: Business recycling the right way Businesses concerned about doing the right thing, both legally and environmentally, with their waste have been thrown a lifeline by Planet Ark, which has developed a checklist for choosing the right recycler to help ensure their business waste is recycled correctly. Under environmental legislation, a business that generates waste may have a legal obligation to ensure the transporter and the facility receiving its waste has legal authority to undertake the relevant activity and may be held responsible if they do the wrong thing. The checklist provides a set of questions to ask a potential recycling service and is available at BusinessRecycling.com.au. According to a 2010 NSW government report, metal recycling generates the greatest environmental benefits. By recycling one tonne of metal, the greenhouse gases saved is the equivalent to taking 2.2 cars of the road permanently, saving 1.8 backyard pools of water and powering 4.6 households per year. As part of National Recycling Week (November 12-18) Planet Ark is promoting the Friday Fling – an opportunity to give your unwanted files the flick. Individuals are encouraged to set aside time on Friday November 16 to de-clutter their filing cabinets, give used paper another life and raise office paper recycling rates. A guide to getting involved is available at RecyclingWeek.PlanetArk.org

new approach. The benefits of which will reduce the overall direct carbon liability a landfill will face. The Waster Management Association of Australia’s national landfill division is currently working with landfill companies and the Clean Energy Regulator to put the finishing touches on the administrative and compliance requirements needed to incorporate customer waste-specific WEFs into a landfill sites emissions reporting system. Of course, with every new approach there are also drawbacks. The added cost of determining and incorporating refined WEFs into a landfills emissions reporting system is not cheap. As such, this new process is likely to only be suitable for the bigger waste generators, who produce relatively stable waste streams and who will benefit financially from determining their waste stream’s specific WEF. In practice, the burden of proving the composition and therefore WEF of a waste stream is on the waste generator and the undertaking of an NGERS-compliant waste audit to determine composition can get reasonably costly. Similarly the added costs of incorporating a specific customer’s waste composition

business + strategy

Specifically, how do I

measure results? In this second instalment in a series of articles about evaluating behaviour shift, Grahame Collier looks at how to effectively and sensibly measure results.

W

hen you’re trying to evaluate a program it is important that you are able to collect evidence against the stated outcomes of the program. If you have precise outcomes, then you are halfway to getting useful information about how the program is going and whether it is driving any change in behaviour. Collecting the evidence is the next important step. Often program planners get

confused about how to collect the evidence. This article helps to lift the veil of confusion and to provide some simple advice about what data collection mechanism works best under what circumstances.

Asking for it

There is, of course, an easy answer to the question: “How do I collect the evidence?” You ask people to give it to you.

The more complex question though is: “How do I ask them objectively, so that I get real evidence about the outcomes I want to measure?” The answer to this question means you have to consider three factors: what questions do you want answered; who has that information; and what mechanism is best for getting it. You have to decide on the answers to the first two questions: this article provides some help with the third question. There are a number of answers to this question and each is outlined below. Advice is also provided about when each mechanism might be most useful.

Hints for the use of various data collection mechanisms and when they work best Mechanism

Best used

Don’t use

Written survey

Written surveys are effective data collection methods when people have time to complete them. For example, after workshops but not in shopping centres.

Unless translated versions of the survey can be provided, these don’t work well with culturally and linguistically diverse communities.

Online/electronic surveys are particularly useful for collecting quantitative data because data can be quantified and calculations done, graphs easily produced etc.

Also, reading age is often a problem with written surveys. Careful testing in the design phase is important.

Telephone survey

Telephone surveys are useful when randomised samples are required or data has to be drawn from a specific population profile.

These do not give the opportunity for the respondent to give an in-depth response. Best suited to quantitative data collection, partly because it is difficult to pre-code qualitative data that might be obtained.

Interviews using a discussion guide

These methods are best used when in-depth information is required. Usually, qualitative questions are used in the discussion guide.

Not useful if quantitative data is required.

Electronic recording is useful but it quite likely has an impact on people’s willingness to share. Documenting group processes

An excellent method when the outcome to be measured relates to the quality of a partnership or the nature of the interactions in a group.

Limited utility for measuring most outcomes.

Project records

Very useful for backing up the responses received from other means.

Limited if the quality of record keeping is poor.

This requires a skilled evaluator and is best used by someone with expertise and experience. Most project managers will avoid this method.

Note: Qualitative data collects and measures information that is opinion/perception based rather than numerically structured. Data tends to be gained by the open-ended questions and be more in-depth; questions of “how”, “what”, “why” tend to be asked. Quantitative data is numerically based. This method tends to ask questions about “how many”, “how often”, “how much”. The answers to these questions can be reported numerically and simply.

Surveys – these are probably the most often used data collection methods, but there are many different forms of survey. Written response surveys: These can be delivered in hard copy or electronically, for example, by Survey Monkey or equivalent, or through an Excel or Word document, delivered on-line. In all cases though, the questions asked must relate to the key evaluation questions for the project. A combination of qualitative and quantitative questions can be asked. Interview type surveys: Telephone surveys are the most-used example of this type of survey, although interview surveys can also be undertaken face-to-face. Surveys, however they are delivered, require a specific and purpose-build questionnaire to be administered. It is poor practice if the interviewer wanders from the survey format. Non-survey-driven interviews – these use a purpose-built discussion guide to collect data from respondents and they are more free-flowing than a survey. Delivery also takes a number of forms, they might be used in on-on-one interviews with key informants or they might be the subject of a focus group discussion. Data obtained is

mostly qualitative and electronic recording is sometimes useful. Documenting of group process, individual perceptions and/or project records – documenting can occur through a variety of means.

‘‘

Observation can take place anywhere at any time and is particularly useful for collecting data about behaviour

Case studies: This method involves the written documentation of ways in which particular individuals or organisations responded to a program. Case studies are both evaluative and demonstrative in nature. Qualitative information can be obtained assisting the evaluation of the program; or the case study can be used as an example of positive practice and learning that occurs. Ethnographic studies: Studies of a group – this provides a written description of the rules, norms and traditions of a particular ethnographic group. It provides real life evidence of activity and the integration of theory and practice within a group.

Observation: Observation can take place anywhere at any time and is particularly useful for collecting data about behaviour. Specific records of observations need to be kept; these include written notes, photographs, video records, audit results etc. Observation as an evaluation method particularly suits programs where behavioural outcomes can be seen (for example, reduction of littering programs). Diaries or journals: The keeping of a diary or a project journal about learning as a result of a program. These are useful for long face-to-face training and/or community development projects and can be used when there is a need to explore attitudes, determinants, processes and/or experiences. They can be totally unstructured, or focus on specific issues or processes. Project records: These also form a part of a high quality evaluation process. Records that might be analysed include minutes of meetings, reports of actions and monitoring information. This is the second in an occasional series of articles about evaluating behaviour shift – how to do it effectively and sensibly. Grahame Collier is principal of T Issues Consultancy (www.tissues.com.au)

Upcoming Feature in December: LTO – Mine Site Management and Remediation The impacts and contribution of the mining sector have been brought to national attention with the Federal government’s mining tax agenda, adding to the growing focus over the last decade on the need for resource companies to secure a social ‘license to operate’. While this starts with scoping and consultation in the development stages, the operational aspects of mine site management and closure are critical. To discuss these latter issues, WME will in December produce a special ‘Licence to Operate’ report focusing on best practice environmental management in mine operations and remediation. • Regulatory requirements • Leading case studies • The latest technologies

water + wastewater

Weather patterns key to water quality Recent research will allow for better management of water resources through understanding our changing climate, writes Richard Collins.

T

he increased frequency of extreme weather events will have a bigger impact on drinking water quality than their intensity, reveals a review by the University of New South Wales. Environmental engineers examined 10 such events from the past 14 years to assess their impact on raw and treated water and on various supply infrastructures. It is critical research intended to help water suppliers make informed planning decisions to cope with climate change. In some of the cases the researchers observed “rapid and unprecedented changes to raw water quality”, along with major obstacles to ongoing provision of clean drinking water due to infrastructure damage and loss of electricity supply to treatment facilities. Interestingly, the most severe impacts on water quality didn’t occur from the most “extreme” events on their own, but from multiple “significant” events occurring in relatively quick succession. “Throughout the case studies we noticed a very stark trend, which was that most of the significant water quality impacts came from a series of sequential events rather than from a single event,” said Dr Stuart Khan, a water quality expert from the School of Civil and Environmental Engineering. He said the finding went against their initial assumption “that increased frequency of extreme weather events would simply lead to increased frequency of the water quality impacts”. Shona Fitzgerald, a research assistant at the university’s water research centre and lead author of the study, put it in perspective: “A one-in-100 year flood seems more significant than a one-in-10 year flood because of the extent of the impact on the catchment and the general population. But, in fact, we found that the water quality impact of a one-in-10 year flood, in combination with other factors,

could be worse than an event considered more extreme, or rare,” she said. The results suggest, for instance, that a bushfire or drought followed by a heavy rainfall event would lead to far worse water quality impacts than either of those events would normally cause alone – even if they were considered very extreme. After a bushfire there is lots of ash on the ground, which contains high loads of phosphorous. In time, this will be stabilised in soil and assist new plant growth, but if a heavy rainfall event comes along before that stabilisation can occur the ash will wash into waterways, leading to detrimental impacts on water quality. A subsequent hot weather event can lead to an algal bloom in water supply reservoirs, further impacting on water quality. “This finding highlights the need to consider combinations of weather events, and their cumulative effects, in planning and preparing for the resulting impacts on drinking water supply,” said Fitzgerald.

Future water availability

The South Eastern Australian Climate Initiative (SEACI) recently released its Phase 2 Synthesis Report, which addressed key science questions behind the causes of climate variability and change and their impact on water availability across the Murray–Darling Basin, Victoria and southern South Australia. It showed there were long-term © Aspermont Limited – courtesy WME

reductions occurring in cool season rainfall across southeastern Australia and that these changes were at least partly attributed to climate change. “The cool season is the traditional ‘filling season’ for water supply systems across most of southeastern Australia, and SEACI research reveals this important cool season rainfall may be less reliable into the future,” SEACI program director David Post said. SEACI research showed the reduction in cool season rainfall was caused by an expansion of tropical influences, driven by the Hadley Circulation expanding at a rate of 0.5 degrees of latitude (about 50km) per decade, pushing mid-latitude storm tracks further south. “Our modelling shows this observed expansion of the Hadley Circulation can only be reproduced if human influences (such as greenhouse gases, aerosols and stratospheric ozone) are included in the models,” said Post. “I think primarily that this change, this decrease in cool season rainfall across southeastern Australia and, of course, southwestern Western Australia is not going to go away. Basically, we’re stuck with it,” said Post. He said the implication of this trend was that water managers must be adaptive in the way in which they planned water use, because they could not rely on that refilling of dams to occur every winter, like it had traditionally.


WateReuse award winners announced Several innovative projects have been singled out this year at the WateReuse Awards, including Victoria’s Gippsland Water Factory.

T

he awards program presented by the WateReuse Association recognised 10 organisations and individuals, from water utilities to technology developers. The award for the WateReuse Project of the Year (Large) went to the Eastern Municipal Water District, California, which has about 25% of its water supply portfolio made up of recycled water. The Gippsland Water Factory was acknowledged with the International Award and the Empire Generating Power Plant with the Industrial Project of the Year Award. Global consulting firm CH2M HILL helped to design and construct both of these facilities.

Gippsland Water Factory

The Gippsland Water Factory is a water purification and recycling system in the Gippsland region of Victoria. CH2M HILL was a member of the alliance, along with Gippsland Water, Transfield Services and Parsons Brinkerhoff, that provided project management, design, construction and operations services of the Gippsland Water Factory. The factory uses technology, including biological treatment, membrane filtration and reverse osmosis to treat nearly 35 million litres per day of domestic and industrial wastewater. It provides purified water to Australian Paper’s mill.

The Empire Generating Power Plant

The facility produces 8-12Ml/d of highquality recycled water for use by local industry. Green engineering principles and design were incorporated throughout the project, including cogeneration of energy from the biogas generated by anaerobic treatment (330 kilowatts) and also a MicroHydro station (340kW) that captures energy from a large clean water stream. The Empire Generating Power Plant uses reclaimed water for cooling/process and natural gas to fire the combined-cycle turbines to 535 megawatts base load or 635MW at peak power, representing the largest beneficial use of treatment plant effluent in New York state. As a result, the facility reduces its need for fresh water by up to 18,169 litres per minute (summer peak rate).

A cleaner way of analysing water

Product: Sigrist AquaScat online turbidity analyser From: BR Controls Phone: (02) 9476 2133 Web: www.brcontrols.com.au

The Swiss-made Sigrist AquaScat turbidity analyser uses a free-falling sample design in which the water sample is never in contact with the cell. The cell measures turbidity through the entire sample by the 90-degree scattered light principle. This contactless design eliminates fouling and the necessity for regular cleaning. Dependability of readings is enhanced by stable Zerodur optics calibration, which is initiated automatically by the AquaScat WTMA or manually by the AquaScat WTM. Both units have a fine resolution of 0.001 NTU for low-turbidity monitoring. For high-turbidity applications, the AquaScat HT will offer the same non-contact reliability in difficult applications. The AquaScat P is for applications under pressure and all models have a range of 0-4000 NTU. The operator interface is a touch screen colour graphic display. The product features a choice of digital outputs and a data logger, which stores data on to an internal microSD card.

With data plans starting from as little as $8 per month (based on an hourly reading of one input transmitted once per day), remote data via satellite now costs about as much as that offered by mobile phone networks. MicroSpider satelliteâ&#x20AC;&#x2122;s combined with Modbus and SDI-12 compatibility provide great flexibility for use with a broad range of instruments. All products include an on-board webserver that allows the user to view and configure all parameters without special software or licences.

Easily investigate the quality of natural gas Michell Instruments has developed a transportable version of its hydrocarbon dew-point analyser. The key function of this version enables engineers to provide a fast response for investigations into the quality of natural gas. The Condumax II measures hydrocarbon and water dew-point (key indicators of the quality of natural gas) in the same way and to the same accuracy as the on-line version. The analyser is fitted into a transport case with a rudimentary sampling system suitable for performing supervised measurement sequences. The system can be loaded into and out of a pick-up truck by two engineers, who will be able to operate and analyse the results on site. This ease of use reduces the reaction time of test measurements as well as the cost. A typical application for the Condumax II would be investigations into the performance of hydrocarbon reduction processing by natural gas producers. The analyser can be brought into operation quickly at any point in the process to help resolve issues.

Title: Corporation 2020: Transforming Economist Pavan Sukhdev, an expert on Business for Tomorrow’s World greening economics and business, returns to Publisher: Island Press (US) Australia in December to share his vision of a Purchase: http://tinyurl.com/8lbdl8j global green economy, explored in his latest Price: $18.95 (hardcover) book Corporation 2020: Transforming Business for Tomorrow’s World. Global in scale and multilateral in approach, the book re-imagines the corporation as an agent for positive change in the economy, society and the natural environment. Sukhdev outlines a path for corporations to transform from cost externalisers to value optimisers and suggests the milestones needed to achieve that change. He describes the problems inherent in today’s market-centric economic model which creates environmental risks, is recession-prone and widens the gap between rich and poor. Sukhdev shows how ‘Corporation 2020’ can rise in the next decade in the effort to avert catastrophic social imbalance and ecological harm.

Accessible guide to becoming a Brand Hero Prompted by their involvement in the Rio+20 Title: The Hero’s Handbook Earth Summit in June, the team from Republic Publisher: Republic of Everyone Purchase: www.onethingivelearned.com.au of Everyone has devised a readable online Price: FREE (.pdf download) publication to champion the efforts of global brand heroes and share some of their secrets to success. The Hero’s Handbook says of the conference “as always, there was good within the ordinary”. The participation of some companies proved there is a significant shift in how companies are approaching sustainability. The handbook is about those kinds of companies; the Microsofts, Unilevers and Pumas. It looks at the rise of Brand Hero and hopes to inspire new companies to also become leaders, “because the world needs more heroes”. Drawing on the experience of the Republic’s work with business, governments and non-government organisations over the past five years, the guide has an emphasis on strategy, creativity and communications.

A conservative philosophy on climate change Title: Green Philosophy: How to Think It’s often difficult for those on the political right Seriously about the Planet to respond to the challenge of climate change. Publisher: Atlantic Books When favouring market solutions which are Purchase: http://tinyurl.com/9o8c295 failing to capture the true cost of business it’s Price: $24.00 (hardcover) hard to see how greater political intervention will not be needed to produce any lasting shifts. While some in the conservative camp tend to deny the science of climate change and its link to human activity, writer and philosopher Roger Scruton does not go down this path. He is critical of agribusinesses, supermarkets and airlines alike for their part in environmental damage. Scruton’s solution is to introduce a flat-rate carbon tax, operating on the “emitter pays” principle, to be applied to products calculated on the amount of carbon released in their production. Interestingly, Scruton favours a technological fix to climate change, either through the development of an alternative source of energy that doesn’t emit greenhouse gases or geo-engineering. © Aspermont Limited – courtesy WME

NOVEMBER 2012 Special Report 2012 Industrial Water Report The commercial and industrial sectors account for about 20% of Australian water use and contribute much of the chemical and other trade waste to sewage. As regulations tighten and efficiency plans become mandatory for big users, the sourcing, conservation, treatment and reuse of water is similarly bubbling up through the ranks of business priorities. In November, WME will publish a major supplement on the latest in industrial water, including business responses, regulatory regimes, innovative case studies, the latest products and technologies and more. The 2012 Industrial Water Report will be essential reading for anyone with responsibility for securing and improving their company’s water management.

: Modern dilemma

Eco-friendly, but is it cool? When Modern Dilemma received an email recently promoting some uber chic accessories with a conscience it conjured up a memory of that idiosyncratic British comedy of the 1990s Absolutely Fabulous. The email was telling me about a brand of sunglasses, made from 100% sustainable wood, claiming to be the first of their kind in Australia. Oh, how times have changed. When AbFab’s Eddie scored the contract for PopSpecs, a piece of hyped up plastic eyewear with tacky interchangeable lenses, her daughter Saffron was probably right to question the logic of calling them “kind to trees” and their right to carry a sticker of a green tree. But as Eddie pointed out in reply, “They’re ain’t made of wood ... how kind do you want them to be?” Now, three brothers with a “soft spot for the planet” have come up with what they describe as “face furniture” like no other. They offer sunglasses and eyewear that are customisable from different wood types and lens options. They donate a percentage of

sales to giving sight-saving surgery to people in India, replant trees in Haiti and even recycle sunglasses. Then there’s WEWOOD out of Italy, marketing its “avant-garde approach to sophisticated sustainability”, the wooden watch. But it gets better. Apparently, the timepiece is as natural as your wrist. “It respects your skin as you respect nature by choosing it.” For each watch sold they also plant one tree. Carrying the message of “look good, do good”, this kind of approach walks a very fine line between super silly and cool. But even if the marketing message for the new face and wrist furniture is a bit lacking in substance, it is worth remembering that sustainability can sometimes spur cool. Think of the Toyota Prius. It did get the ball rolling in the automotive world and now both Lotus and Porsche are on the hybrid bandwagon ... sorry, high-performance road furniture.

OCTOBER 2012 : WME magazine

A giant green cube made from recycled crates and 25,000 edible plants grown by Sydney residents and businesses emerged in Green Square in September as part of the city’s annual public art festival, Art & About Sydney. The Great Crate, a fully recyclable installation 10m high and 10m wide, towered above the entrance to Green Square train station at the busy intersection. Scientists blame higher levels of carbon dioxide in Pacific Ocean waters caused by global warming for the failure of oyster seeds to thrive in hatcheries, which caused a 60% drop in production in 2008 and an 80% drop in 2009 for some US producers, and may in the future affect the taste of the product. Labour councillors in the Netherlands want to impose fines on erroneous weather forecasters, pointing to claims that incorrect reports of rain and thunderstorms are hurting the tourism industry, following similar threats from Belgian hotel and restaurant owners saying they would sue their weather bureau. A giant goddess sculpted from rock, earth and waste reclining in the remains of a coal mine in northern England was unveiled by Princess Anne recently. She declared the 400m long naked female form open to visitors who wished to take the 20-minute walk around the quirky attraction. © Aspermont Limited – courtesy WME
