Contractor spend on SMEs revealed Lucy Mair

The Cabinet Office has revealed what some of the government’s main contractors spend with SME subcontractors on central government projects, with Interserve topping the list by awarding the highest proportion of work to SMEs. Details of how much subcontract money goes to SMEs was published as the government revealed overall direct SME spend increased to £4.5bn last year, up from £3bn in 2009/10. Interserve headed the roster of main contractors cited in the Cabinet Office’s Making government business more accessible to SMEs: Two years on report, with almost 70 per cent of its supply chain spending going to SMEs when delivering work for central government clients. It was closely followed by Laing O’Rourke, which awards over 63 per cent of its supply chain spend to SMEs on government projects. Bam Nuttall and Lend Lease each give more than 55 per cent of their work to smaller subcontractors, while Galliford Try awards just over 45 per cent of its spend.

The information was supplied by main contractors for the report, which also claimed that the government has now delivered £2bn-worth of work through project bank accounts. Despite SMEs accounting for just over 10 per cent of spend at present, the Cabinet Office said the government is ‘on target’ to ensure 25 per cent of its procurement spend goes to SMEs – firms with fewer than 250 employees and a turnover of less than £43m – directly and through the supply chain by 2015. Overall spending with SMEs in 2012/13 was down in percentage terms at the Department for Culture, Media & Sport, Department for Work and Pensions, the Home Office and Ministry of Justice compared with 2011/12.

It remained level at the Treasury but rose in all other departments, most notably at the Department of Health (indicative percentage increase of 4.8 per cent based on indirect spend for the period October 2012 to March 2013) and HM Revenue and Customs (6.1 per cent). Other companies cited in the report included Emcor, which spent 52.8 per cent of its supply chain spend with SMEs; Wates, on 50.6 per cent; Jackson Civil Engineering, with 50.4 per cent; and Appleyards Professional Services, on 57.8 per cent. Interserve executive director Bruce Melizan said: “Where possible, Interserve has modified its procurement systems to allow the future identification and tracking of activity with SMEs.” Mr Melizan added that Interserve’s standard tendering process asks subcontractors to provide examples of using SMEs in their own supply chains, which has enabled the contractor to increase its spend with SMEs.

BETTER TIMES MAY JUST BE EMERGING Following a raft of announcements proclaiming growth in both the economy and our industry over the past few weeks, several of them covered by H&V News in this issue and the previous one, it seems that we can look forward to increased levels of business in the future. While this will inevitably mean playing the waiting game for some, especially where commercial projects are concerned, the fact that most of the recent studies cover this year’s second quarter means that some sectors have enjoyed improving conditions for several months. We are obviously a long way off the trading conditions we saw before the crash in 2008, but there is now considerably more reason for an optimistic outlook than in the previous five years.

The mood of contractors and installers is cautious optimism rather than all-out celebration, but this is the most sensible approach”

Renewables march

The 2014 H&V News Awards will see the event celebrate its 20th anniversary with another ‘must attend’ night of celebration at London’s Grosvenor House Hotel, where competition will be fierce to take home the building services industry’s most highly prized trophies.

The number of hybrid systems installed in the UK is forecast to continue to increase as installers and contractors get better at combining different technologies in one system and endusers realise the benefits of their successful implementation.

With more clarity recently published on both the domestic version of the Renewable Heat Incentive and the government’s Energy Bill, supported by recent statistics showing the increased use of renewables in UK energy generation, continuing growth is expected for renewable energy technology.

The mood among many contractors and installers around the UK is better described as cautious optimism rather than allout celebration, but this is by far the most sensible approach. A glance at this week’s Opportunities section (see page 12), shows that although Glenigan’s forecast for the offices sector is positive, activity continues to vary quite dramatically from region to region. As I’m always critical of the national media and various doom mongers that I believe make difficult economic conditions even worse, I feel duty bound to counter this by hailing the recent signs of improvement. A full recovery might not yet be a reality, but we are at least moving in the right direction.

Commercial property hits highest levels since 2007 Mark Smulian

Commercial property sector activity is at its highest level since May 2007, property firm Savills has reported. The balance between respondents reporting more or less activity stood at +20.1 in July, up from +18.9 in June. Both private and public newbuild activity in the sector rose in July, with respective net balances of +25.9 and +1.4. Growth in private new-build work was the strongest recorded since May 2007. Commercial developers told Savills they were optimistic about the prospects for the sector over the coming quarter, with a balance of +25.1 viewing the outlook positively, up from +14 in June.

The sharp rise in confidence bodes well for development activity in the second half of the year” Positive sentiment was linked to improving client confidence, better weather conditions, higher enquiry numbers and increased availability of bank financing. Savills director of building consultancy Michael Pillow said: “The sharp rise in confidence bodes well for development activity in the second half of the year. “Developers will continue to

Police warn of Mafia involvement in renewables The Mafia is increasingly investing in renewable energy schemes, according to Europol. These initiatives are proving increasingly attractive to Italian organised crime groups, says Europol in its Threat Assessment: Italian Organised Crime report, because they offer generous grants and tax subsidies, combined with the opportunity to launder money from criminal activities. This is part of the Mafia’s ongoing efforts to infiltrate the legal economy, the report explains. It uses wind farms, which attract well-publicised and generous grants, as an example. The Mafia has been linked to wind energy projects in the US and Europe, including Spain.

be restrained by a lack of debt but this should help ensure a sustainable recovery.” The sharp rise in industrial and warehouse activity in July breached a record for the survey, increasing from +26.3 to +32.6. The net balance for private office activity (see page 12) was +30.8 in July – the strongest increase in more than nine years. The net balance for private retail and leisure work fell slightly from +14.3 in June to +12.2 in July, but was “consistent with a solid expansion nevertheless”, Savills said. Both office fit-outs and refurbishment work also rose strongly. For the 11th month running, commercial activity rose across all three categories, most rapidly in London at +31.6.

Construction industry survey reports improved fortunes Dina Patel

The latest Construction Trade Survey shows conditions in Q2 improved across all construction sectors and throughout the supply chain. Small and medium-sized businesses, hardest hit by the downturn, reported their first rise in activity since 2007. Private housing was one of the key contributors to the improving workloads, together with a ‘catchup’ across many sectors following a poor first three months of 2013, when adverse weather significantly affected output. Prospects also showed signs of improvement, with manufacturers, specialists, civil engineers, and SME contractors all reporting



Percentage of contractors citing a rise in building work year on year more orders for future work. The survey found that 72 per cent of building contractors reported a rise in building work on an annual basis, on balance, compared to flat output in Q1. Building activity increased across all sectors, with improved conditions most frequently reported in housing; a net balance of 42 per cent of contractors working in private housing and

40 per cent of those working in public housing reported rises in output year on year. Civil engineering workloads were broadly unchanged for the third consecutive quarter, although 5 per cent experienced increased orders. SMEs saw the first rise in annual output since 2007 Q4 and a net balance of 5 per cent of firms reported a rise in enquiries. Managing director of Skanska’s mechanical and electrical business Martin Neeson said his company had won commercial office and prime residential contracts in the London area this year. “Private overseas investment is the main source of the upturn, with public investment continuing at the low levels experienced in recent years,” he said.

News round-up Safety, biomass, business, energy, gas leak ESC responds to LRS

The Electrical Safety Council has welcomed the introduction of the London Rental Standard (LRS) as a positive development but is concerned it does not go far enough in improving electrical safety. The LRS – one of Boris Johnson’s campaign commitments during the last Mayor of London elections – aims to raise standards in the city’s booming private rented sector. The voluntary accreditation scheme contains a series of minimal standards around 12 core commitments, ranging from fees and deposits, to landlord and letting agent training. However, references to safety standards simply state that landlords must comply with current legal requirements, including having no category 1 or significant or multiple category 2 hazards.

JTL has launched a website to provide instant access to good, reliable information on electrical, plumbing and heating training. The company is a training provider in the electrical sector and claims a track record of apprentice achievement. The website is multi-purpose and visitors will be able to get the latest information on apprenticeship opportunities from the perspective of employers, potential new apprentice recruits and also the parents of young people considering entry into the trades. The online resource brings together relevant case studies that illustrate what can be achieved by employers taking a positive attitude to training opportunities.

Tilbury B Power Station has marked its final day of electricity generation after 46 years of operation and a combined total of 57 years of service. The station has played a role in the UK’s power generation mix since it began operation in 1967 as a 1,467 MW coal-fired plant. During its lifetime it generated 168.8 TWh – enough to keep three billion light bulbs burning for more than a year. The station was scheduled to close under the EU’s Large Combustion Plant Directive (LCPD), which gave it 20,000 hours of operation from 1 January 2008. Gas leak evacuation

Letters Chimney products must have CE marks and be tested Dear Sir, I would like to bring to your attention a change in regulation. As of 1 July 2013 all chimney products used in construction work or refurbishment must be CE-marked where a harmonised EN Standard or a European Technical Assessment exists. This is required by the Construction Products Regulation 305/2011 and applies to all construction products. Although companies can claim CE approval, unless the relevant independent tests have been carried out this may not be acceptable and the installer or the specifier concerned could be held responsible. Our company was recently asked to install a gas appliance in a chimney with a T200 specification lining, which was not suitable for the appliance – the data plate stated Class 2 appliances only. A visual inspection from the

base of the chimney also revealed that the lining had been badly installed and the flue was severely restricted – by about 50 per cent. When we raised this with the contractor on site he said he could get the data plate changed and if we would not install the appliance, he would find someone who would. This statement caused us considerable concern, as this could be a threat to property and even life. The CE mark is a ‘passport’ allowing a product to be sold throughout the EU, but it does not mean that the product is fit for purpose. For that, it must still be tested and certificated to the relevant standard for the chimney or flue product and subject to manufacturing quality audit in order to ensure constancy of performance. Signing off on a chimney or flue installation without proof of performance carries an unacceptable risk of prosecution

If a product is not CE marked, or it is but fails to meet the required standard, the seller or supplier can face jail”

if the product cannot meet the requirements of the Building Regulations. If a product is not CE-marked, or if it is but fails to be of the required standard, the seller or supplier can face imprisonment or a large fine. David Fleming, technical sales director, Chimney Care

Your view on best advice on the use of refrigerant

H&V News’ LinkedIn group responds to the question: R22 to R410a – is it still ‘best advice’? to join the group and offer your opinions, visit:

This debate will run and run. The R22 that was discontinued in 2010 had a lower global warming potential – an ozone depletion of 0.05. The decision to push the R410a, I would suggest, was again probably a political rather than a environmental decision. Having only just got the RHI through, the world’s first long-term financial support programme, we are held purely by the powers that be...”

I think you are quite right about sticking to R410a within the air conditioning sector but I feel that is because there are no real alternatives. The majority of clients will want the most cost-effective solution in the ongoing tough financial climate and although the odd piece of kit is being released soon, there are no full or competitive ranges”

Until the industry and more importantly end clients make the choice, it is best to stick to R410a. The next choice depends on the different markets, namely refrigeration or air conditioning. I have never been a great believer in retrofitting R22 systems with new refrigerants. This is asking a client and a contractor to accept another company’s installation work”

I think we should let systems alone for a few years. All of the refrigerant issues came about as a result of leakage into the atmosphere (global warming). I also don’t have a problem with so-called natural refrigerants, but we don’t have the skills base to deal with LPG and ammonia. It’s about jobs for the EU proletariat, not understanding the financial implications to commerce and industry” 21 august 2013 11

However, intelligence provider Glenigan expects this period of slowdown to make way for renewed growth in the sector towards the end of this year and throughout 2014. The regional breakdown during the second quarter reveals a clutch of strong performances balanced out by some notably weak areas. As usual London led the pack for offices activity, its starts for Q2 representing around 43 per cent of the UK total. However, the capital’s total was marginally down on 12 months earlier. The figures from the traditionally strong regions of the North-west and South-east were even more worrying, while many of the typically weaker areas of the country were true to form with single-figure values of starts over the three months. However, Scotland, the West Midlands and Yorkshire & the Humber all recorded both strong absolute totals and impressive year-on-year gains, led by activity in Glasgow, Birmingham, Leeds and Sheffield. Among the major projects that started on site in Q2 were a £60m 10-storey office block and commercial development in Glasgow for client Duddingston House Properties, which has appointed Sir Robert McAlpine; a £20m office fit-out project in Birmingham for Wragge & Company, undertaken by Wates Construction; and a £15m four-storey office development in Leeds for Muse Developments, being built by Morgan Sindall.

official data suggests that the economy is tentatively recovering and sector surveys reveal greater optimism as a result. Consequently, the pipeline for the offices sector has picked up in this year to date, having weakened during the second half of 2012. Glenigan figures show that the value of planning approvals in the sector in the first five months of 2013 returned to the healthy levels recorded in the same period of last year. This should ensure that the momentum building towards the end of this year carries over into the next; accordingly, Glenigan expects a 25 per cent rise in the value of starts for 2014, provided of course the wider economy continues to heal.

NSCC SPECIALISTS MARGINS The latest National Specialist Contractors’ Council’s State of Trade Survey shows a strong turnaround in the margins being made by specialist contractors during the second quarter of 2013. The figures show the net balance of those specialists reporting a rise in margins during the first three months of 2013 minus those experiencing a decline. Within the net balance, 38 per cent of those companies surveyed reported falling margins, far fewer than the 61 per cent seen in Q1; 7 per cent said that margins had increased, while the remaining 55 per cent reported no change. While poor margins are still clearly an issue, these numbers suggest the situation improved markedly in Q2.

The balance between those experiencing rising tender prices and those seeing falls stabilised somewhat in Q2 2013 after successive quarters of wild fluctuation. Nevertheless, the majority of specialists continue to report declining prices, with the net balance standing at -26 – up three points from -29 in Q1. Within Q2’s balance, 13 per cent of specialists surveyed said tender prices had risen over the quarter, while 39 per cent reported contractions; 48 per cent reported no change. This is at least far more positive than the -45 posted in Q4 2012 – the weakest level recorded since Q3 2010 – and is also 13 points higher than the corresponding period of 2012.

NSCC EMPLOYMENT EXPECTATIONS The NSCC’s net balance of employment expectations among specialists has soared since bottoming out in Q3 2012, hitting +23 in the second quarter of 2013. This figure marks a six-year high for the data and represents an increase of 28 points over three quarters; it is also higher than the same point in 2012. The figures show the net balance of those specialists anticipating a rise in employment levels over the coming quarter minus those predicting a decline. Breaking Q2’s net balance down, 31 per cent of respondents expected a rise in their staffing levels, compared with 20 per cent in Q1; just 8 per cent predicted a decline, down from 15 per cent previously.

Special report Awards

anniversary awards set to be bigger than ever The H&V News Awards celebrates its 20th year in 2014 and will once again offer an evening of networking and celebration The industry’s favourite event will be celebrating its 20th anniversary next year when the H&V News Awards, long established as ‘the industry’s Oscars’, comes back to London’s Grosvenor House. The awards are the highlight of the building services calendar – recognising and celebrating innovation and excellence in the industry. Headline sponsor Pipe Center sales and marketing director Scott Craig says: “This year’s awards were a stunning success. “As headline sponsor, we were delighted with the level of support we received from the industry, and the sheer professionalism and quality of the event itself.” The comedians and presenters H&V News Awards attracts are some of the best in their industry and have included Jo Brand, Jonathan Ross, Lee Hurst, Jimmy Carr, Patrick Kielty, Rob Brydon and Jon Culshaw. For 11 years the awards were held at Park Lane Hilton before moving in 2006 to the Grosvenor House Hotel. Speaking about what it means to win an award, GSH Group regional operations director Steve Wallis says: “It’s hard to believe that a decade has passed since I was named Apprentice of the Year from H&V News. “This award raised my visibility throughout my company, GSH Group, which permitted me the opportunity to explore GSH’s other operating regions.

“Today, working outside of New York City, I am on the US management board of GSH Group with responsibility for managing key client accounts across the country. “H&V News played a key part in the success of my career and I advocate that all aspiring apprentice engineers dedicate themselves to this truly amazing industry.” Change with the times

Some of the categories have remained the same but many have changed over the years and others have been updated to reflect the industry. The Rural Heating Installer Award was introduced in 2010. Sponsor Calor says: “Calor is delighted to be once again sponsoring the Rural Heating Installer Award at the H&V News Awards. “The event is a great opportunity to network with our key installer market and celebrate the hard work the installers carry out in the rural heating market. “In particular in the 20th anniversary year of the awards, it’s an even better opportunity to get together as an industry to commemorate what we’ve achieved but also look forward to the next 20 years.” In 2013, the event attracted more than 1,000 people, providing yet more proof that the industry’s Oscars are recording growth in all areas. This year saw a momentous

shift for the awards, following a significant updating of the adjudication system, another increase in entries for the third consecutive year and an inaugural pre-awards reception evening. The number of judges was increased to more than 50 for the 2013 Awards, following an industry-wide recruitment campaign last year. This has allowed dedicated groups to judge a single award, further raising the integrity of the event. Judges from leading companies such as NG Bailey, Norland Managed Services, Skanska and GSH attended judging days last March, joined by representatives from leading industry organisations including B&ES, HHIC and FETA.

Special report Awards (continued) once again exceeded expectation in quality and quantity – highlighting those who are pushing the boundaries of innovation and excellence in the building services industry. With more than 50 esteemed industry experts and face-to-face interviews this year, the awards boasted even more integrity and credibility, ensuring beyond any doubt that the best candidate won on the night. Sponsor Plumb Center says: “It’s the industry’s equivalent of the Oscars and Plumb Center is delighted to back the 2014 H&V News Awards, as they celebrate their 20th anniversary. “This year we are again sponsoring the Energy Efficient Installer of the Year award because

we passionately believe that engineers can help transform the way we all heat our homes.” Plumb Center says renewable technologies such as biomass, solar thermal and heat pumps are just a few of the energy-saving solutions on offer, and have the added bonus that they can be integrated into conventional systems. But at a more basic level, big improvements can be made with heating controls, insulation and double-glazing. The company also says they want to hear from installers who, through their hard work and determination, are making a difference to the energyefficiency of people’s homes in their communities. An appeal for judges for next

Special report Hybrid systems

Combine technologies for best end results The benefits of using different technologies in a single system to meet owners’ and users’ demands is becoming more widely understood The trend for hybrid HVAC solutions, incorporating a number of technologies in a single system, has steadily increasing as building service engineers become more comfortable with how these can work effectively in tandem. The trick, of course, is to identify the best options to deliver the desired end result while meeting budgetary and legislative requirements. Installers and contractors continuing to specify the same solutions based purely on habit may find themselves losing out to competitors that bring more diversity to the table. An important point to understand is that renewable technologies can combine with traditional systems to deliver significant benefits in almost any building, says Vaillant commercial director Mark Derbyshire. “Hybrid solutions offer the best of both worlds, complementing each other’s strengths and weaknesses to provide environmental, fiscal and installation advantages,” he says. “The benefits for those in off-gas properties are even more profound. “The reassurance of a gas boiler combined with the prospect of lower energy bills and the satisfaction of doing your bit to reduce carbon emissions opens up the prospect of renewables to a far wider audience.” Intelligent weather compensation controls allow switching to the most efficient heat source

automatically, he adds. Furthermore, hybrid systems will qualify for payments under the domestic Renewable Heat Incentive scheme next year, providing the renewable heat is metered. “For many UK homes, hybrid solutions are the ideal compromise between practicality and sustainability. With the added incentive of cashback, we can expect to see their popularity ascend,” Mr Derbyshire says. Ample support

A hybrid system allows renewable energy options to be supported at times of reduced performance, explains Hamworthy Heating business development manager Kevin Potter, who offers the example of solar thermal combining with high-efficiency gas combustion technology in a single, self-contained heating and storage vessel. “This solution takes up less space, as it does not require an auxiliary heat source and can be installed close to the point of use, minimising distribution heat losses,” he says. A hybrid solar water heater features twin-coil construction where one coil can be supplied with hot gases from a fully modulating down-firing gas burner designed for optimum efficiency; the other coil, rising from the bottom of the unit, can be supplied with solar heated water, when connected into a solar circuit.

We must be adaptable to ensure we take advantage of the products we have at our disposal” Lee Baxter, Myriad Solar

The heating circuits act in tandem, with the solar circuit providing heat whenever collector temperature is just a few degrees above that of the stored water at the bottom of the tank. “When stored water temperature falls below the combustion thermostat setting for gas burner operation, the controller makes an assessment of available solar energy,” Mr Potter continues. “If sufficient solar energy is available, the burner operation will be held off. However, if the store temperature continues to fall, the gas burner will be brought into operation to heat the water.” Hybrid systems provide 21 august 2013 21

Special report Hybrid systems (continued) crucial steps toward a greener fuel source and a step away from complete reliance on fossil fuels, says Worcester, Bosch Group director of marketing and technical support Martyn Bridges, who also cites the combination of boilers and solar thermal. “Even on cloudy days during the winter months, a wellsized solar system of two panels can provide up to 60 per cent of a home’s annual hot water requirements, enabling a reduced dependence on the boiler, as well as lower energy bills,” he says. “A twin coil cylinder is typically installed when the solar panels are being positioned on the roof; unsurprisingly, the replacement of older hot water cylinders affords greater efficiencies.” Heat pumps are another viable option and ideal for autumn and spring when heating is required at reduced levels compared with mid-winter. Although these currently make up 1 per cent of the overall heating market, awareness of the technology’s benefits is increasing, he continues. Initiatives such as the HHIC’s Hole in the Roof are helping communicate the benefits of a change in approach and the Green Deal and the RHI could help kick start a wider interest in these technologies, but there needs to be a real push from merchants and installers alike in promoting hybrid systems in a clear and straightforward way, Mr Bridges says. The increase in hybrid systems also offers new business and servicing opportunities, he adds. “With the market changing, it’s worth investing in the latest training and being able to offer customers the latest technology and the installation capability. “In the future, I’d like to see manufacturers, installers and policy-makers working together to promote the benefits of heat pumps and solar thermal, in combination with gas or oil-fired boilers as a hybrid system. We need to encourage more customers to 22 21 august 2013

regard it as a step towards bridging the gap between renewable and traditional heating products.” Twin advantages

The benefits of integrated systems are both financial and environmental, Kingspan Environmental specification design manager Stephen Kelly points out. Retrofitting microgeneration technology allows the original boiler to provide back-up, while cutting bills and emissions, he says. “In winter, for example, a solar thermal system can pre-heat the water in the hot water cylinder, reducing demand on the boiler,” Mr Kelly adds. “In summer, the system can replace the boiler completely for hot water generation.” Particular attention should be given to ensure solar thermal systems provide the highest contribution to domestic hot water across the year: sizing the solar system and storage capacity accurately will provide optimum savings and reduced payback. Controlled properly, microgeneration systems provide the base load energy requirement while using traditional heat sources to provide the remainder of the energy during peak demand. “Using both traditional and microgeneration technologies offers property owners more choices and reduces dependence on fossil fuels,” Mr Kelly says.

This solution takes up less space, as it does not require an auxiliary heat source and can be close to the point of use” Kevin Potter, Hamworthy Heating

Challenging conditions

The use of hybrid systems will be further increased if installers learn

Lower bills and reducing emissions opens up renewables to a far wider audience” Mark Derbyshire, Vaillant

to work within environments which are more challenging, says Myriad Solar PV general manager Lee Baxter. “I’m talking about installing new technology into old buildings – where issues such as planning regulations, strong designs and the aesthetics come massively into play,” he says. Emphasising the need for industry innovators to adapt to challenging environments, he highlights the challenges of a recent project integrating a solar energy system into the renovation of a Grade II-listed property near London’s Oxford Circus. “Immediately, you are faced with numerous design and planning considerations and complications,” Mr Baxter says. “You are talking about designing a PV system to sit over plant and structures, such as air-handling units, pipework and walkways, with challenging specifications.” Co-ordination between the architect, main contractor, consultants and building information modelling specialists covers aspects such as designing the system steelwork correctly. “We must also work to not just meet but exceed the client’s renewable energy targets as well as provide client training for the system,” he adds. “It is all about energy at the end of the day but PV is extremely complementary to a lot of other renewable technologies. “We must also be adaptable in order to ensure we take full advantage of the products we have at our disposal.”

Special report Renewable energy

Sustainable expansion ahead on all fronts? Demand for renewable energy installations is set to grow in the coming years and industry professionals are well placed to benefit Renewable energy installations will continue to be a growing market for domestic and industrial customers in the coming years. Building services contractors operating in the industrial sector are also likely to see demand for more renewable energy installations, following recent government figures showing that these are accounting for a larger share of UK energy production. The recent Energy Bill aims to encourage more investment in this area. Biomass and anaerobic digestion have attracted more attention this year, along with large-scale solar projects, and H&V News has also heard predictions from a number of sources of a rise in community energygeneration projects in 2014. One of the more recent largescale solar projects to receive planning permission is a 20 MW installation at Old Romney, Kent. Similar to other examples emerging in the UK, this will be installed on farmland and will see 82,000 solar panels fitted, each with a capacity of 45 W. The project, overwhelmingly backed by Shepway District Council, is the result of a joint venture between Dublin-based BNRG and London’s Lightsource Renewable Energy. For the microgeneration sector, confirmation of tariffs for the domestic Renewable Heat Incentive, due for launch next April, was positive news, as was the updated 24 21 AUGUST 2013

study on heat pump performance by the Energy Saving Trust (H&V News, 14 Aug). The latter shows that householders can save about £1,350 a year with air-source heat pumps, with ground-source heat pumps providing about £3,000, based on current RHI tariffs. Improved performance

The heat is on: heat pump field trials phase 2 was published earlier this month. Since the first study was unveiled in 2010, a number of recommended interventions have been taken, most of which have improved performance. This is further reflected in the EST’s survey of heat pump owners, with 80 per cent of respondents stating they were satisfied with performance. Interventions included the installation of replacement units in some cases, while others were less dramatic. Most of the heat pumps studied were installed in 2008, and the EST pointed out that units installed today were likely to be more effective thanks to advances in technology, installation recommendations and best practice guidelines in the Microgeneration Certification Scheme. The combination of the EST report, Renewable Heat Premium Payments and the commercial Renewable Heat Incentive, as well as an enthusiastic reception for news on next year’s domestic RHI, could drive an increase in MCS registrations as the industry

gears up to tap into the government funding available. Flogas marketing manager Chris Aston highlights further potential developments. Consumers interested in alternative technologies and fuels are turning to heating engineers to recommend the best solutions, he says. “For installers wishing to compete in the modern market, now is the ideal time to get on board this growing industry and be able to advise their customers through the decision process and fuel options available on the most energy-efficient solution,” Mr Aston continues. “To take advantage, installers

need to recognise their role as an adviser. Knowledgeable installers are more likely to be able to recognise where homeowners could make long-term savings on their energy bills by switching to LPG, particularly in the case of an oil user. An installer who possesses an in-depth knowledge of LPG is more likely to recommend or discuss the fuel’s benefits with a homeowner. “The future is looking bright for the market as eco-conscious consumers seek new technologies. The role of the installer is crucial in this process and knowledge is essential to take full advantage.” The government has previously come in for considerable criticism over its handling of schemes such as the Feed-in Tariff

and the delays and lack of clarity surrounding the RHI, but there has been a more positive response to recent announcements, according to 4Eco director Jodi Huggett. “We were delighted to hear the long-awaited news of a domestic heating incentive planned for introduction in the UK,” she says. Fuel poverty

Ms Huggett points out that in a time of fuel poverty, where utility prices are rising and natural resources are under pressure, consumers are struggling to pay for their energy consumption. “This means that embracing alternative techniques to reduce costs and conserve natural supplies is essential,” she says. “Although the DECC has been

running a commercial incentive since November 2011, homeowners desperately needed a support programme to encourage greater uptake of renewable technologies.” Without financial backing to encourage the switch to green power generation, many homeowners were struggling to pay their bills, which could be easily solved by investing in sustainable solutions, Ms Huggett says. “The RHI is an excellent progression in the renewables sector and will make a real difference to the future of green power generation in the UK,” she adds. “The scheme will help homeowners to embrace eco-solutions and reduce utility bills, minimise mains supply reliance and protect the environment.”

Better business Air conditioning legislation, humidification effects air conditioning

New rules could trouble facilities managers A combination of different factors regarding air conditioning and duct maintenance have changed how facilities managers should approach those systems. Awareness of new legislation and issues are necessary to steer clear of a summer of workplace disruption. Building owners, services companies, maintenance companies, end-users and consultancy and control companies are all affected by the recent British Standards EN 15780 legislation. This deals with cleanliness of ductwork used for ventilation in commercial buildings, focusing on providing proper assessment criteria for cleanliness and cleaning procedures. The legislation applies to new and old systems, implemented in part to deal with ventilation ductwork being left in unclean condition immediately after installation. As well as the BS EN 15780, new legislation is coming in 2015 that bans R22 refrigerant from being used as the primary coolant in air conditioning systems. Although R22 has long been an industry standard for air conditioning, it is now being phased out due to environmental concerns. New substances such as R410-A will be used instead, requiring specialist, qualified installation engineers to manage the changeover. This is not only costly but can be time-consuming, depending on the size of the system. This may then leave facilities without air conditioning for a significant length of time. Updates loom

With both R22 and BS 15780 legislation pending, many facilities’ systems will need to be updated or replaced in the coming months. 26 21 august 2013

In addition, many systems may not be properly maintained due to managers underestimating their value. The danger of systems no longer being fit for purpose suggests the importance of regular maintenance for both air conditioning and duct cleanliness. When it comes to ducts, ensuring compliant levels of cleanliness are maintained is imperative, especially following installation, modification or refurbishment. When temperatures force air conditioning units to work to capacity, having a system that is ill-equipped to cope can at best create unpleasant and unproductive working conditions, and at worst seriously disrupt businesscritical processes. Productivity cost

Without an alternative plan in place, productivity levels of employees could be seriously reduced if the air conditioning suddenly stops working. Employers have a duty of care to their workers to make sure the work environment is comfortable. Keeping the temperature in the office within the ‘Goldilocks zone’ – not too hot, not too cold – keeps morale and productivity high and also cuts error rates and reduces employer liability risks. Employers and facilities managers should consider the benefits of hiring portable air conditioning units as part of a contingency plan in case of an emergency. This will allow those responsible for the HVAC of a commercial premises to cope with any unforeseen breakdowns or other maintenance issues, with minimal disruption to work environments.

These issues do not just affect commercial properties; they also impact hotels, restaurants, schools, hospitals and laboratories. It is crucial for anyone involved in maintaining and regulating air conditioning to take notice of legislation and maintenance guidelines. Regular maintenance is preferable to emergency procedures, and can prevent expensive remedial work including potential legal action down the road. stewart Owen is sales director at andrews sykes


Humidity crucial to cutting impact of airborne flu A recent study carried out by the US National Institute for Occupational Safety & Health (NIOSH) has shown that the airborne transmission of the influenza virus is significantly reduced by maintaining an atmosphere of 40 per cent relative humidity (RH) and above. In order to test the effects of humidity on airborne influenza, aerosols of flu virus were ‘coughed’ into a room’s atmosphere by a mechanical manikin at humidity ranging from 7 to 73 per cent RH, while the air intake

This study shows how important it is to maintain an optimum humidity to reduce absenteeism”

from a breathing manikin in the room was monitored. The air inhaled by the breathing manikin showed that at ≤23 per cent RH the airborne flu virus retained 71 to 77 per cent infectivity, while at ≥43 per cent RH infectivity dropped to just 15 to 22 per cent. The study showed that inactivation of the virus at the higher humidity occurred rapidly after coughing, with most of the decline occurring in the first 15 minutes. The study concluded that maintaining relative indoor humidity at 40 per cent RH and above will significantly reduce the infectivity of an aerosolized influenza virus. Economic impact

It is estimated that more than 7.6m working days are lost in the UK each year as a result of flurelated sickness, costing the UK economy more than £1.35bn every year. Most experts believe flu is spread by tiny droplets created when people with flu cough or sneeze, which can remain in the air for hours. This study shows how important it is to maintain an optimum humidity in the workplace to reduce absenteeism and especially in areas of high risk to airborne viruses, such as hospitals. Although many professional bodies, including the BSRIA, CIBSE and HSE, all recommend maintaining indoor humidity at above 40 per cent RH, it is not uncommon to see humidification systems being turned off to reduce operating costs. Low humidity is not as noticeable by employees as a low temperature, so it can go unnoticed. However, the cost of not maintaining indoor humidity can be poor staff health and an increase in absenteeism, which can far outweigh the cost of operating the building’s humidification system. tim scott is sales & marketing director at Js Humidifiers

Better business: technical Reverse osmosis, industrial cooling steam plant


steam operators can save with reverse osmosis

solutions abound for eco-friendly industrial cooling

A combination of recent technical innovations and increasing pressure to save energy means that today’s reverse osmosis (RO) systems could help many steam plant users who may never have considered RO before. RO is a robust, chemical-free technology that uses semipermeable membranes to deliver purified water to boilers and clean steam generators. It is a wellproven technology, but now growing numbers of steam system operators are finally wising up to the potential benefits. RO can deliver a range of advantages, but the biggest driver for most steam users to invest in RO until now has been the need to save energy and reduce costs. That need is intensifying as climate change measures evolve and grow teeth at the same time that energy prices continue to rise. Of course, no single technology can entirely mitigate these, but RO can make a major contribution by cutting fuel bills by as much as 3 per cent for typical steam users. RO is commonly used in conjunction with water softening, chemical dosing or filtration to deliver purified water to boilers and clean steam generators. By stripping out almost 99 per cent of the dissolved solids, RO can reduce boiler blowdown by an order of magnitude, resulting in significant savings in energy, water and treatment chemicals.

Can you cool your factory or warehouse and protect the environment? This is a problem that has vexed business owners as they try to balance their costs against the need to work responsibly. Anybody who works in the factory or warehousing industry knows climate control is crucial. However, it can also be expensive and polluting, and this pollution can hit the company in its balance sheet and lose potential custom. Industry has in the past had the unfortunate reputation of being one of the world’s great polluters. However, this image is now changing through responsible companies who know that clean air means a clean reputation. With a greater awareness for green matters coupled with the obvious business need to improve efficiency, companies are increasingly looking at ways to keep costs down and to reduce their emissions. A company with a negligible CO2 footprint can boast a major PR victory. As green technology advances at a growing pace, business owners can take advantage of several technologies to cool their premises without costing the Earth.

Tackling new rules

Tighter controls on the level of lead permitted in drinking water will come in at the end of 2013. One of the ways water companies are responding is to add phosphate to water supplies as a corrosion inhibitor that prevents the

lead in old pipes from dissolving. Left untreated, phosphate can precipitate and cause scale when it reacts with calcium or magnesium in the boiler water. Typically this happens when the boiler water becomes too hard. Avoiding this involves constant management of the alkalinity of the water in the boiler, adding chemical dispersants and ensuring the level of dissolved solids is kept in check through regular boiler blowdown, all of which could be time consuming and costly. RO can virtually eliminate the phosphate before it reaches the boiler. It uses a pump to force a stream of water through a semipermeable membrane, separating it into two streams. One is the reject stream or concentrate stream and the other is the purified water or permeate stream. The permeate typically flows to a holding tank or hot well before being sent to the boiler or clean steam generator. RO membranes do not need to be regenerated using the acid or the caustic chemicals used in conventional dealkalization or demineralisation plants. This makes RO generally safer and easier to manage. Virtually all steam users stand to benefit from RO, whether they are tackling hard water in hospitals or fighting contamination in food factories. Used in combination with the right treatments, RO helps cut down on plant outages caused by scale and reduces corrosion in the condensate circuit. Mike griffin is steam system conditioning manager at spirax sarco

Emerging methods

One of these methods is the use of ‘green cooling’ towers that take advantage of evaporative cooling. As water evaporates, it removes excess heat from the area and cools any circulating fluids to safe temperatures. Green cooling towers go a step further by using a design that allows the towers to work without electric motors, with the obvious reduction in energy bills. Evaporative cooling towers can range in size from small rooftop units to

Not only does solar air cooling not need electricity to cool the factory, solar energy can also be used for heating” large, free-standing structures. Solar air cooling uses solar panels to collect energy and then use that energy to power fans. This method is especially green because it is self-sufficient. Not only do factories using solar air cooling not need electricity to cool the factory, solar energy can also be used for factory heating. Technology in solar panels has advanced greatly, with unit prices plummeting as their efficiency improves. Even where sunshine is not always guaranteed, their use makes increasing sense. A third method is through the technology of heat exchange. Heat exchangers make particular sense for both factory heating and cooling. Hot air is run through ducting past ducts of cooler air, resulting in highly efficient temperature reduction. The technology also is impressively efficient for cooling hot liquids. Renowned for their efficiency and simplicity, heat exchangers are used in everything from small appliances to large spaces such as factories and warehouses. As technology advances, it’s increasingly clear that industrial cooling can be eco-friendly. New developments mean processes that were previously highly polluting are now more efficient, cleaner and cheaper than before. Jonny Craft is a freelance writer for COsaF

A team of cyclists from Mitsubishi Electric has conquered the annual London-to-Brighton cycle ride and beat its fundraising target for the British Heart Foundation. Twelve members of staff from the firm’s Hatfield and Milton Keynes sites participated in the event and raised more than £2,600. In all, 28,500 cyclists joined in the ride, which started at 6.30am at Clapham Common. The 55-mile route winds its way through south London, Surrey and Sussex.

River quest Fifteen rowers from Interserve tested their endurance for the second year running as they took part in the gruelling 444-mile Yukon River Quest in Canada in a bid to raise £100,000 for Help for Heroes. Competing against 66 other crews from across the world, the team began the race on 26 June in Whitehorse, Yukon Territory, Canada and raced day and night to reach Dawson City before midnight on the 29 June – resting for only 10 hours during the race.

Two-thirds of small business bosses were only “reasonably familiar” with their legal obligations.
