And when the dust settles...

I

have said this ad nauseam, but when the property market was racing at Shinkansen speed and when district cooling occupied lavish mind space, from Dubai to Doha and from Manama to Cairo, the odd lament about the need for best practices was lost in the noise, though in all fairness, it must be added that the International District Energy Association (IDEA) did release a Best Practice Guide for the industry at its Third International District Cooling Conference and Trade Show, in 2008 in Dubai. What was also lost in the melee was a call for better treatment of the end-user, who after all, plays such a critical role in building a positive perception towards district cooling.

The common excuse was, “Yes the end-user is important, but one needs to prioritise, considering there are a gadzillion opportunities to erect district cooling plants and to lower more and more pipes into trenches.” The excuse had the tacit approval of many that were ever so eager to capitalise on the momentum.

Today, the mood could not be more different. Starting from end-2008, when Lehman became a menacing symbol of the meltdown, to now, when there is considerable uncertainty engendered by floundering Greece and a handful of Euro-zone nations, district cooling has taken a pounding, the intensity of which has arguably intensified by the day. The viability of district cooling as a financial model itself has come for the severest test. While the challenge needs to be addressed, we ought not to lose sight of the original but unaddressed challenge – of satisfying the end-user, whose number, in recent times, has been dwindling. After all, a happy and convinced end-user is akin to an insurance, once the economy recovers in the region, and district cooling is once again in favour.

There could be no better time than now to appease the end-user, through a sensible and sustainable metering and billing regimen. There is an urgent need to increase the scope for the customer to save on his district cooling cost, through better allocation. In other words, there is a need for obligations to allocate the cost on consumption basis, fully backed by rules and regulations laid down by the Government.

It is imperative to define cooling charges, the way they ought to be defined. That way, there is an incentive for the end-user to save and, thereby, realise the oft-touted potential of district cooling. Then, once the dust settles, district cooling will have one less front to confront with as it begins the slow and onerous task of regaining lost ground.

Tabreed reports healthy account books despite hiccups Company rides on chilled water wave to register profit

A

ccording to the recently released first quarter 2010 consolidated financial results, Tabreed has registered a healthy profit.

For the three months ending March 31, 2010, Tabreed’s total revenue was reportedly Dh184.6 million – broadly similar to the corresponding period in 2009. However, the company reports that the net profits more than doubled over the same period in 2009 – from Dh21.7 million last year to Dh43.8 million in 2010.

Excluding minority interests, Tabreed’s share of profits, it explains, was Dh40.4 million compared to Dh10.8 million in the previous year.

During the first quarter of 2010, Tabreed added four new plants to its portfolio, enhancing 27,000 TR of capacity and bringing Tabreed’s total installed cooling capacity to 422,100 TR across 40 plants.

According to Tabreed, the

surge in profit was thanks to its core business of chilled water. As a result of three new plants coming online in 2009 and four new plants coming online in the first quarter of 2010, it recorded sales of Dh117.1 million – an increase of 91% over the same period last year.

In effect, profits more than doubled – up by 109% – to Dh22.8 million. Margins for the chilled water business reportedly improved from 18% to 20%.

Tabreed’s wholly owned subsidiary, Gulf Energy Systems (GES), was the biggest contributor to the strong results, particularly reflecting GES commissioning the chilled water network on Al Reem Island and signing Dh60 million of new orders for the Sowwah Island network project.

Tabreed also added that the company’s contracting segment recorded sales of Dh 36.1 million – an increase of 37% over the same period last

year. Profits for the segment were Dh15.6 million.

However, Tabreed’s manufacturing segment reported sales of Dh15.6 million – a significant decline from Dh81.4 million for the first quarter 2009 – due to a significantly reduced order book. Profits for the manufacturing segment were Dh0.7 million.

During the quarter, Emirates Pre-insulated Piping Industries was awarded three new projects, valued at approximately Dh25 million, which are expected to be completed by the second quarter of 2010.

Again, Tabreed’s services segment, which is involved in the design and supervision of building electrical and mechanical works, reported sales of Dh15.9 million – down by 23% over the same period in 2009 – reflecting reduced order books from the slowdown in the economy.

Profits for the segment were Dh5.5 million – unchanged

over the same quarter in 2009.

According to Tabreed, as of March 31, its total installed cooling capacity is 422,100 TR across 40 district cooling plants. The Company expects nine more plants to come on stream in the remainder of the year.

Commenting on the overall positive picture, Sujit S Parhar, CEO of Tabreed, said: “The first quarter 2010 results demonstrate the significant progress we have achieved to date in reengineering the business and implementing corporate governance and process controls. We have a strong core business of chilled water and a steady pipeline of new plants coming on stream.

We will continue to focus on improving operations and actively managing facilities. We acknowledge the challenges facing the business in the year ahead, and those associated with our recapitalisation process, but we are confident in the long-term prospects for the Company.”

Acquisition of DSQ fuels horizontal expan Reflects confidence in the Qatar economy, company says

D

rake & Scull International PJSC has announced the completion of the acquisition of Drake & Scull International Qatar, LLC (DSQ), a Mechanical, Electrical and Plumbing (MEP) contracting company in Qatar.

According to DSI, the decision to acquire DSQ came following a series of stringent financial and legal due diligence and feasibility studies carried out by SHUAA Capital, PricewaterhouseCoopers and Al Tamimi & Company.

“With this move, we have made significant progress in meeting our strategic objective to increase DSI presence in the region, thus enhancing our access to a broader range of construction opportunities,” said Khaldoun Tabari, CEO, DSI PJSC. Calling the acquisition a reflection of the company’s confidence in the Qatar economy, with its tremendous longterm growth potential, Tabari added: “DSQ is a prominent player in the

market with strong management that brings us complementary capabilities and greater geographical diversification.

Reaffirming our ongoing commitment on profitability, the acquisition will also have an immediate positive impact on both our backlog and bottom-line performance, with strong potential for continued growth going forward.”

According to IMF forecasts, Qatar’s real GDP growth is projected to rise by seven per cent in this year alone,

Steve Ridlington, CFO, Tabreed, added: “In addition to operational improvements, we have also taken steps to implement a more rigorous financial discipline and focus on efficiency for our business, both of which are evident in the results announced today. Our efforts have translated into the best first quarter results in the company’s history.”

Reiterating Parhar’s comments, Khaled Al Qubaisi, Managing Director, Tabreed, said: “While we are very pleased with the first quarter results, which reflect the hard work of the management team under the direction and supervision of the Board, we recognise that there are challenges that face the business in the year ahead.

We are confident, however, that the improvements in the company, and the way its business activities are conducted provide a strong platform to achieve the company’s objectives of improving performance, increasing profitability and maximising returns.”

Talking of the sensitive issue of recapitalisation, he said, “The initial discussions we have had with key stakeholders in respect of the recapitalisation of the company is positive and encouraging. The support from major 2008 Sukuk holders for the company’s decision to defer the May 19 payment is a strong endorsement of the steps being taken to complete the recapitalisation process.”

“An exclusive session with Don” garners positive feedback Industry expert stresses use of TSE and seawater during DC Summit

D

on Eppelheimer, Global Chiller Systems Manager, Trane, attended the Second Annual District Cooling Summit held in Jeddah, Kingdom of Saudi Arabia, on April 19 and 20, and shared his expertise with participants.

Speaking during the preview of the event about multiple heat rejections systems, Eppelheimer compared and contrasted the characteristics of large aircooled, water-cooled and dry cooler radiator systems that are commonly used today.

Observing that water and power supplies are short everywhere, and Saudi Arabia is no exception, he said: “Today, there are solutions to makeup water loss, using reverse osmosis plants, condensate collection, eliminate evaporation or even better use of Treated Sewage Effluents. Chilled water systems can also be made to operate using seawater, when the installation is in proximity to the sea, as is the case in the

eastern and western provinces of Saudi Arabia.”

During his visit to the region, Eppelheimer toured Egypt, Lebanon, Kuwait and Dubai, where Trane customers could benefit from an interactive session held exclusively for them, between April 15 and 22.

In a seminar titled, Chiller Plant Design – An Exclusive Session With Don, he addressed gatherings of consultants, designers, specifiers and district coolinh service providers in these countries. The topics under discussion were: ‘Variable Primary Systems (a detailed coverage)’; ‘Earthwise Design (an overview)’ and ‘Refrigerant Update’.

Eppelheimer, who has been involved in the development and support of HVAC systems for Trane since 1972, and a recognised expert within the industry, reportedly garnered positive response for his presentation. According to the customer feedback received, the presentation

pirated products. It is bad for Danfoss’ reputation and endangers our sales,” said Li Zhu, Global Anti-counterfeiting Coordinator, Danfoss, China.

All the seized products are now stored in a government warehouse in Dubai, and will be destroyed.

The products include 7,800 filter driers, 1,565 expansion valves, 1,575 orifices, 212 compressors, and 1,625 product labels.

Danfoss Property investigates and files lawsuits against businesses that sell fake Danfoss products. The department expects to file lawsuits against the companies in Dubai and conduct major anti-counterfeiting investigations and raids in other countries soon.

DSI stretches its reach to Oman

company says Move fulfils strategic objective to increase presence in the region

D

rake & Scull International PJSC (DSI) has recently announced the establishment of its newest subsidiary, Drake & Scull International Oman (DSO), specialising in Mechanical, Electrical and Plumbing (MEP) contracting. The move, DSI claims, will not only allow the company to further strengthen its presence across the Middle East and North Africa but will also result in a greater flexibility to diversify its operations and backlog.

“Our focus over the last year has been to expand our business geographically and vertically, and the decision to diversify into Oman follows this very philosophy,” said Khaldoun Tabari, CEO of DSI. “In today’s challenging global economic environment, a well-planned expansion strategy can help us reduce costs, gain access to new markets and talent pools, and most importantly, can provide a healthy pipeline to fuel our company’s growth and shareholders’ return,” Tabari elaborated.

“The value of projects in Oman that are set to go ahead in 2010 – at the prequalification, bid or engineering, procurement and construction stage – are estimated at $22 billion, highlighting the wealth of potential that the country has to offer,” concluded Tabari.

According to DSI, since the formation of DSO, the company has already been awarded its first contracts for two government projects, worth a combined value of Dh44.2 million (OMR 4.6 million). DSO will undertake the complete MEP works for the Sohar Court Complex (SCC) located in Sohar and the Oman National Museum (ONM), located at the footsteps of the Hajar Mountains in Muscat.

DSO will begin work immediately on SCC, which will include six court halls, staff and judges’ offices, a cafeteria, guard house and an external plant room, and is estimated to be completed within 13 months. DSI reports that

the company will simultaneously commence with the ONM project, which upon completion, will display over 6,000 years of the country’s history and culture, and will feature 10 galleries, classrooms and studios and an indoor café. The ONM project

completion handover date is slated to be September 27, 2011 and the museum is scheduled to open to the public on November 11, 2011.

DSI has earlier worked with the Oman government on the development of the Sultan Qaboos Grand Mosque.

Tour & Andersson organises seminar on variable flow techniques Concludes that simple methods can provide long-term energy saving and reduce installation costs

T

he recently held seminar organised by Tour & Andersson in Abu Dhabi, titled, ‘Investment and Energy Saving Opportunities in Variable Flow Systems’, addressed the key issues surrounding variable flow and looked various ways in which temperature fluctuations and inadequately sized variable speed pumps (VSPs) can create a negative effect on the efficiency of the entire system.

Considering the need to reduce energy use, the seminar discussed how the correct placement and sizing of a variable speed pump can help minimise the energy used in the system, whilst still operating to the same high level.

The seminar, attended by 134 delegates, was well received.

Sabah N Mohammed, MEP Manager from Al Bayaty Architects, said, “The seminar was informative and increased

Qatar Sustainability Conference brings key stakeholders together QSC 2010 helps place Qatar favourably on the international sustainability map

L

aunched under the theme of ‘Energy and Water Efficiency’, the Qatar Sustainability Conference 2010 was held from April 13 to 15, with the avowed objective of fostering sustainable policies, products and services and best green practices in building and technologies.

Held at the Doha Exhibitions Center, the conference was inaugurated on April 12, in the presence of sustainability experts, speakers and key stakeholders in the construction industry, such as architects, civil engineers, landscapers, mechanical engineers, agents, manufacturers and suppliers.

Organised by IFP-Qatar, the conference was concurrently held with Project Qatar 2010 – the 7th International Trade Exhibition for Construction Technology and Building Materials.

The second edition of the three-day event aimed at closely examining options for alternative energy sources, particularly water and solar power. It also acted as a platform for experts from the construction industry to address green-sensitive issues through learning, engaging, exchanging and partnering to find solutions for the sustainability of the planet.

One of the major aims of the conference was to encourage fruitful collaboration between the government, NGOs and private entities to prioritise on the use of sustainable building technologies that are designed to minimise environmental damage, despite the high cost and long return on investment of sustainable solutions.

As a part of the exercise to demonstrate the efficiency of solar and water energies via already implemented projects in Doha and worldwide, local, regional and international case studies of scale were closely examined.

The first session of the conference welcomed Mohamed Jaber, Chair of the Education Committee in the Qatar Green

Building Council (QGBC), whose mission is to increase awareness among people by developing a set of environmental and green building best practice guidelines through research and development. Jaber shared with

the attendees his views on ‘Holistic Approach to Green Building Design’.

The conclusion of day one also saw distribution of trophies to the speakers

by IFP-Qatar, in recognition of their efforts and inputs.

Manlift Power supplies 27MW temporary power to Qatar’s Gulf Cement Company Logistical operation included transporting specialised equipment from Dubai to Doha.

T

he UAE-based Manlift Power, dealing in temporary power projects, has announced its largest power supply so far – the delivery of 27MW (Prime) of temporary power – to the Gulf Cement Company (GCC), Qatar, within 10 days.

Manlift installed 27 Cummins 1250kVA Powerbox units, synchronised into a central power package, producing 27MW of power, running at 6.6kV. The award of this contract is an extension of the 17MW temporary power project that Manlift Power had been operating since May 30, 2009, for the GCC in Qatar.

According to Manlift, the first tranche of power was fully operational on April 2. The logistical operation included transporting specialised equipment from Manlift’s head office in Dubai, to Doha, while ensuring that the tight timeframes and specific production requirements requested by

the client were met.

Manlift reported that it is the sole power supplier to the GCC plant, which reportedly has a capacity of producing in excess of 6000 tonnes of cement every day.

David King, General Manager, Manlift Power, Qatar, said: “This project is a true example of the high levels of professionalism and knowledge that we offer our clients. The GCC project highlights our tremendous capabilities for delivering multi-megawatt international power projects, under tight time and logistic constraints.

I’m very proud of the Manlift Power team, both here in Qatar, and in Dubai, and we look forward to a fantastic extended relationship with the GCC.” Adam Ashcroft, Regional Director, Manlift Power, added: “Building upon our previous successful performance in Qatar for GCC, we are delighted to have successfully undertaken this

extended contract. Manlift has an impressive proven track record of supplying turnkey temporary power solutions, and is fast becoming the chosen supplier in the region for both single unit and multi-megawatt rental projects.”

Manlift Power, Manlift Group, supplier of access platforms and power generators for sales and rentals, is a joint venture between local shareholders and a European rentals company. It operates alongside Manlift Middle East.

Energy efficiency award is music to Warsaw Chopin Airport

Trane, a business of Ingersoll Rand, honours airport for sustainable practices.

I

n recognition of its commitment to energy efficiency and environmental stewardship, the Warsaw Chopin Airport was recently honoured with the Trane Energy Efficiency Leader Award.

The airport, which serves Poland’s air travel with regular air traffic, charters and cargo, reportedly accommodated 8.3 million passengers in 2009 – approximately 45% of the entire passenger air traffic of the country. The airport’s new terminal features energy efficient infrastructure systems that are also regarded as environmentally responsible. It is estimated that during the first 10 years of operation, these systems will save an amount of

energy equivalent to that needed to supply a city of 11,000 inhabitants for a year. The terminal’s expansion is scheduled to be completed in March 2011.

According to Ingersoll Rand, its Center for Energy Efficiency and Sustainability, which selected the airport for the award, comprises international experts, who integrate the best practices for the long-term use of energy and other resources. They also develop solutions which advocate green policies, standards and education in the communities in which Ingersoll Rand operates and serves.

The consortium was avowedly created by the company as part of its commitment to responsibility towards the environment.

Phaesun will present latest off-grid solutions

Solar-powered refrigeration container to be unveiled at Intersolar Europe trade fair

P

haesun will reportedly display their latest solutions for the off-grid operation of refrigeration containers at their booth at the Intersolar Europe, a trade fair for solar technology, being held in Munich from June 9 to 11.

To be used in hospitals, medical supply depots and food storage centres in regions with insecure or unavailable energy supply, the new solar refrigeration container is claimed to have a storage capacity for a reserve of three consecutive days without noteworthy solar irradiation.

Designed by ILK Dresden, for whom Phaesun distributes the container solutions, the system has a modular structure, including integrated solar modules with a capacity of 1.7 or 3.6 kilowatts, depending on the respective design. The larger system consists of a single cooling chamber for the storage of up to 400 kilogrammes of meat or vegetables at a temperature of 0ºC to 10ºC. The smaller container includes three separate chambers for the storage of drugs at temperatures from 0ºC to 8ºC, 10ºC to 15ºC and 22ºC to 25ºC. The maximum ambient temperature amounts to 52ºC. The containers being flexible, they can be adjusted to customer requirements.

According to Phaesun, the standard container can be easily transported by truck, train, or helicopter and is, therefore, suitable both for stationary applications and for use in different locations.

The company issues a 10-year guarantee on the main components.

In addition to the refrigeration container, Phaesun will display a solar module with integrated lithium-iron battery, produced by the Chinese manufacturer, Build Your Dreams (BYD), for the supply of a streetlamp.

Lithium-iron batteries are believed to be many times lighter than gel batteries, while providing the same capacity. “Moreover, their energy density is by far higher,” said Tobias Zwirner, Managing Director, Phaesun GmbH, explaining the advantages of the battery technology. By comparison, a gel battery with a capacity of 150 ampere hours weighs approximately 50 kilogrammes, depending on the manufacturer, while a lithium-iron battery weighs only 28 kilogrammes. Moreover, the number of cycles of a lithium-iron battery is up to four times higher than the number of cycles of a lithium-iron battery, and up to six times higher than those of a gel battery.

Solar water pump and cleansing systems, as well as a hybrid system and a wind power station are also among the other offgrid solutions to be presented at the Phaesun GmbH fair booth.

Since being founded in 2001, Phaesun GmbH, headquartered in Memmingen, Germany, specialises in the sales, service and installation of off-grid photovoltaics and wind energy systems. It also offers solutions for energy supply and telecommunication.

EZ Trap

S

aying that condensate traps are recommended by the International Mechanical Code to eliminate conditioned air from inefficiently escaping through condensate drain lines in both residential and commercial HVAC units, Airtec has introduced EZ Trap as an addition to its series.

Airtec, manufacturers of air diffusion, condensate management and lineset ducting products, claim that the new product is the HVAC industry’s only cleanable solution that prevents microbial-laced ambient air infiltration entering into commercial, residential and mini-split air conditioning airstreams through the drain line and air handler. They add that the product also reduces air conditioning efficiency in negative pressure systems and also prevents energy loss due to conditioned air being expelled through the drain line on positive pressure systems. Thus, it addresses both health and green concerns.

Salient features of EZ Trap are: • It comes with a line of condensate traps, condensate overflow cutoff switches and other accessories.

• Transparent condensate traps that help “see the problem”.

• Easily cleanable PVC trap in both standard “P” trap configuration and configurations for all air conditioning systems brands and models.

• “Waterless” configurations that provide the benefits of a trap without the presence of standing water that can be used for conventional split systems, commercial rooftop units and minisplit units that feature a mechanical trapping method.

• The traps automatically drain bacteria-generating standing water and eliminate the danger of clogs, dry trap or freeze damage, while providing all of the benefits of a standard trap.

• Comply with the International Mechanical Code that mandates a condensate drain line trap.

Other features in the line are: • The EZ Trap 100 and 200 Series feature adaptable Schedule 40 1-inch and 3/4-inch-diameter crosses, tees and other fittings to accommodate field installation challenges.

• The 200 Series of SmartTrap kits come with integral float switch overflow protection mounted in the trap, which can be field-installed to activate a visual or audible warning alarm.

• The 220 Series has microswitch overflow cut-off switches.

• The 300 Series

UltraSwitch is a selfevacuating electronic overflow switch with an integral mini pump that evacuates the drain pan, cutting power to the unit and continuously pumps the melting evaporator coil ice from the condensate pan and requires activating a manual reset to restart the unit after troubleshooting.

• The 600 Series of kits provide a trap for the primary drain pan outlet to prevent infiltration of unconditioned air and a cut-off switch for the secondary drain pan outlet to provide overflow protection.

Weathermaker – pioneers in pre-fabricated ducts In 1992, Weathermaker Ltd became the first commercial automated ductmanufacturing plant in the region. Mashkoor Hasan speaks of the role played by the plant in the UAE.

U

ntil the early 1990s, in the UAE, HVAC air ducts were being fabricated manually by HVAC contractors, either in their workshops or at project sites, using conventional machines and tools. While, the system was suitable for small projects, it could not meet the requirement of larger projects in terms of demand and quality.

In order to meet the demand for major projects, ducts were being imported in a semi-assembled condition from Saudi Arabia, which was the only country with a commercial duct

manufacturing factory in the Middle East. The knockdown ducts were being sorted out and assembled at site. The process, over the years, experienced various drawbacks and difficulties like, segregation time, missing parts and assembly coordination, resulting in accumulation of wastage of parts and re-fabrication at site.

In 1992, Voltas Ltd, an electromechanical and air conditioning service provider from India, with a major presence in the UAE and the Middle East, took the initiative in this regard, and set up its first commercial, automated, state-of-theart, duct-manufacturing

plant in the Jebel Ali Free Zone, Dubai. It was named Weathermaker Limited. This was a step towards changing the environment of the HVAC duct system sector.

Thus, Weathermaker Ltd started its journey with debut projects like the Shaikh Khalifa Medical Centre, Al Ain Airport, Madinah Zayed Central, the Gold Market and the Taweelah Power Plant. With professional staff, backed by technical and managing competency of Voltas Ltd’s international wing, soon, the concept of pre-fabricated ducts gained momentum and was widely appreciated and accepted by all major MEP and HVAC contractors and consultants in the country.

It was not long before the concept gained popularity, to the extent that a few MEP contractors opted to set up their own in-house facilities.

Since its entry into the market, with its strategic location in Jebel Ali, Weathermaker Ltd has served

its customers across the UAE. In the year 2000, Weathermaker Ltd launched its own brand of duct transverse connectors – slideon flanges. It was tested and certified by BSRIA, in accordance with DW/TM1 standards. The Flanges are the first in the Middle East to be manufactured on a fully automated CNC-controlled machine, with a capacity of 20 metres per minute.

Over the period of 17 years since its inception, Weathermaker, with its customer-friendly approach, technical back-up and close coordination with the site management team and onsite solutions that it provides to clients, has become the ducts and accessories manufacturer and supplier of choice in the UAE. It boasts of prestigious association with iconic projects in the country, like the Emirates Palace Hotel, the Intercon Hotel, the ADNOC Headquarters, NBAD Headquarters, Yas Marina

Circuit, Al Wahda Mall, Burj Khalifa, Emirates Towers, Mall of the Emirates, Palm Atlantis, Jumeirah Beach Residences, Discovery Gardens, Dubai, Etisalat Buildings in Abu Dhabi, Dubai, Sharjah and Ajman, Abu Dhabi Mall & Trade Centre and Marina Mall, Abu Dhabi. It has also been associated with global projects, like Queen Mary II, the Male International Airport, Maldives, Apollo Hospital, Mauritius, Balcona Resort, Mauritius and the Bahrain City Centre.

The Weathermaker team was instrumental in the execution of over 2000 metric tonnes of ductwork, with dedicated manufacturing facilities at site for Hong Kong’s International Airport at Chek Lap Kok, under patronage of Voltas and AEH JV. In view of the growing market and increasing demand for diversified products in the sector, in 2008, Universal Weathermaker Factory LLC

was established under the umbrella of the Universal Group of Companies, owned

by Shabeeb Al Dhaheri, a wellknown personality in Abu Dhabi.

The new facility, spread over a 60,000-square-foot plot in Abu Dhabi’s most modern industrial city, ICAD-I, is equipped with a state-ofthe-art plant capable of producing 600 metric tonnes of ducts per month. The factory has been operational since January 2009.

At Weathermaker Ltd, apart from specialised ducts – stainless steel, black carbon steel, aluminium and fire-rated duct, we also manufacture high quality associated duct accessories such as, slide-on flange systems, plenums, access doors, volume-control dampers, motorised dampers, sand-trap louvres and silencers. In addition, the facility has the expertise to cater to customer-specific requirements on accessories.

The custom-built control system for motorised dampers for one of the projects, manufactured by Weathermaker Ltd, is illustrated here.

Being aware of the importance of well-designed and fabricated friction-free air distribution system, at Weathermaker Ltd, we ensure that quality of the ducts and accessories we supply meets international standards and recommendations set by HVCA DW144, SMACNA, ASHRAE and Eurovent.

Weathermaker is also an International Associate member of SMACNA, which helps the company keep itself updated with the latest developments in the industry.

Blow hot, blow cold Munawar Shariff elaborates on the current market situation for compressors in the Middle East.

O

ne would think that, with summer here, the compressor market would be booming, but given the lingering downturn, the market, as per many industry insiders, is not as good as in 2008 but is steadily becoming positive. “The situation is different for each market, says Uday Mahadeokar, Marketing Manager, Emerson Climate Technologies. “The UAE is recovering slowly, what with the slowdown in new constructions. Abu Dhabi is still strong. Dubai is making a very slow recovery. Other parts of the Middle East are still strong and haven’t slowed down as much as the UAE. Kuwait, Jordan, Bahrain are all recovering slowly. Of course, volumes of trade will never reach 2008 levels when every economy and market was growing, but it’s positive as compared to a few months ago.”

It’s not surprising, then, that the mass reduction in spending has led to a completely different set of needs. In district cooling, for example, the two drivers are new constructions 22

CLIMATE CONTROL MIDDLE EAST

May 2010

and existing machines.

Since there is a major drop in new constructions, businesses are concentrating on maintenance of existing machines. District cooling exclusively used centrifugal compressors, for their ability to provide operational economy and reliability, especially for large building complexes. Now the emphasis is on small-sized compressors, with a big focus on efficiency on the kilowatt per tonne, as centrifugal compressors are known to be very efficient.

Screw compressors, which are widely used in Europe and Japan, are called Variable Flow Refrigerant (VFR) systems. These are attractive currently, as they are the latest products, technology-wise, and are environmentally friendly. The refrigerant, R410A reportedly has high efficiency at partload operations. For most of

its life, it runs at 40 to 80% capacity and, then, switches from full capacity to partial load. Modulating from using the most electricity at highest loads to pumping less and using less electricity when the need for cooling reduces, this enables the refrigerant to have a lower carbon footprint and not use full power continuously.

However these refrigerants are currently not being used in the Middle East. The most common refrigerant in the region is the R22 refrigerant, which is known to be ozone depleting, whereas the R410A does not deplete the ozone layer. Awareness of the qualities of the R22 refrigerant is widespread, but that hasn’t stopped companies from using them.

“This is because the region comes under the category of developing countries, and the use of this refrigerant

SASO announced a standard, last month.

ESMA has announced a plan to have standards in place by the end of the year, with implementation by mid 2011.

is allowed in developing countries till 2030,” Mahadeokar says. “Developed countries cannot use this refrigerant, and so they are using the R410A.” R22 refrigerants are hydrochlorofluorocarbons (HCFCs), and R410A refrigerants are hydrofluorocarbons (HFCs).

The latter are crucial in the non-damaging elimination of use of the former refrigerants.

HFCs aid in conserving more energy and provide quicker cooling. Having said that, an R410A machine requires stricter installation procedures by certified technicians, a small detail which can be overlooked.

To get value for money from existing investments, developers are placing huge emphasis on energy efficiency and on reducing the carbon footprint. Says Liju Thomas, General Manager of Al Arif:

At Trane, When it comes to energy And the environment, We never FolloW. We LeeD.

with the highest percentage of leed accredited green building professionals in the industry, it’s no wonder trane has received recognition for its energy and environmental stewardship in virtually every category. as a charter member of the clinton climate initiative and platinum sponsor of greenbuild and the leed for schools initiative, trane has the direction, strategies and global coverage to make a powerful contribution in the fight against global warming and climate change.

product focus “More efficient use of energy is the way forward.

There is an increasing demand for water-cooled chillers now because of their energy efficiency, and people are very meticulous about getting value for money.”

Says Mahadeokar: “Our main focus these days lies in two areas, one is energy conservation. And the other is trying to engage different bodies in trying to promote environmentally friendly refrigerants.”

Energy conservation is an important factor which needs to be established with regulatory authorities like the Emirates Authority for Standardisation and Metrology (ESMA) and Saudi Arabian Standards Organisation (SASO). These are the main regulatory bodies that ensure efficiency in air conditioning standards are put in place in the region. Emerson also works with the international regulatory body, the Air Conditioning Heating and Refrigeration Institute (AHRI), as a neutral player.

They are taking the initiative to bring the original equipment manufacturers (OEMs) and regulatory bodies together by preparing presentations with these bodies and presenting them to Dubai Municipality in order to establish energyefficiency standards. Says Mahadeokar: “We have seen success. SASO announced a standard, last month. ESMA has announced a plan to have standards in place by the end of the year, with implementation by mid 2011.

Other Middle Eastern countries are also quick to be on par. Kuwait has upgraded from January of this year and is focusing on energy saving and technology production. Every country is actively starting to adhere to standards and upgrading them every two to three years; reflecting this trend are the OEMs. They have new 24

product ranges with ecofriendly refrigerants, and it can easily be predicted that in the next three to five years, there is going to be a 50 to 60% rise in the use of these energy-efficient and ecofriendly refrigerants in the region.

A most important trend today is the VRF modulated technology. Says Mahadeokar: “Modulated technology depends on how long the air conditioning is running.

Normally, we don’t want the unit to run continuously, hence the modulated compressor, depending on the load. This technology is getting very popular today.

The percentage share of VRF will definitely increase in the near future.”

The VRF Modular compressor trend goes hand in hand with Dubai Municipality’s green initiative, which is calling for individual metering. In such a regimen, consumers are able to track their individual meters and have a direct impact on their consumption levels and the bills they pay each month so they can get the benefits of using less. The current system has less incentives for reducing bills as, usually, a building complex has three big chillers, and every house or office does not have the ability to track their usage.

What about the business end of things? Issues being faced by larger compressor companies and smaller companies in the market differ in a big way. Eapen says: “For our company, Al Arif, business has not decreased; in fact, it has increased. But the biggest problem in the market right now is receiving payments.

So although there are plenty of jobs out there, we’re not committing ourselves, unless payments have been secured.”

Eapen says he follows his gut when it comes to finalising contracts with clients. “We have experience

This is a small market place, and word gets around if a certain company is defaulting on payments.

All then stay clear of the company. If we don’t get a 50% advance payment, we don’t go ahead with the contract, because the initial 50% covers our material cost.

in the market,” he says.

“It’s not difficult to gather intelligence. This is a small market place, and word gets around if a certain company is defaulting on payments.

All then stay clear of the company. If we don’t get a 50% advance payment, we don’t go ahead with the contract, because the initial 50% covers our material cost. A loss in labour cost can be absorbed, but a loss in material cost cannot be absorbed. But there have even been occasions where we have received the LPO and no payments have materialised.”

Not only is receiving payments a big issue currently but also the availability of only a few contracts and a lot of companies quoting for them. Says Eapen: “We’ve been in the business for six years. There have always been plenty of companies and jobs, with the possibility of acquiring projects much higher before the recession.

Now there are few jobs and a large number of companies, including direct suppliers, vying for projects. Recently, there was a project for Dubai College where they had a need for chiller and package units. Fifteen companies quoted for them, including direct suppliers.”

But Eapen is leaving no stone unturned to retain his share of the market. “Now we have to knock on more doors than we did in the past. We are establishing our client base on credibility, keeping a balance of sales and expenses.

It’s not the right time to think about doubling the size of the company. It’s enough that we’re running on profits and not losses. We’ve always been in the maintenance market. Today, our work is 50% new installations and 50% maintenance of existing units.

Exploring new markets is not on our agenda, as we are a very small company of only 25 employees. So we are focusing on the local market.”

The contractors and subcontractors on the job were trained in sustainability practices that they can use with other LEED jobs. We’re creating the green collar workforce of tomorrow. p6

Engineering conservation In an interview with Climate Control Middle East, Phil Barnett, Property Manager at Grand Hyatt Dubai, gives an insight into the various initiatives the hotel has taken to make it environmentally sustainable. The article also brings to light the fact that engineers are often the unsung heroes in the battle of conservation.

A

hotel is a microcosm. Running it is akin to running a small community of diverse people with varying needs and demands. And to run it efficiently and economically is a challenge.

Add the dimension of making it an environmentally sustainable undertaking, and it becomes a balancing act. Phil Barnett should know. He, as the Property Manager of Grand Hyatt Dubai, is familiar with its inner workings. He knows that behind all the glitz and glamour, a luxury hotel needs to have a welloiled and complex machinery that keeps the establishment running.

As a longtime resident of Dubai, with his relevant and rich experience at Hyatt Regency Deira, he has brought to the table innovative measures that are helping make Grand Hyatt Dubai environmentally sustainable.

THE POWER OF AN IDEA During his time at Hyatt Regency, Barnett was instrumental in installing a condensate reclamation system in the hotel. Thanks to the system, Barnett and his team were able to capture cold water runoff from chilled water coils, which they collected and piped to cooling towers as make-up water for the cooling towers. “The best part of the unique measure was that the condensate water was very cold,” Barnett says. “That, in itself, was a

step forward in terms of savings, as it cut down on refrigeration plant power consumption. So, on partially humid days, we got 25 gallons a day of the water. Since cold water is being sent into a system that is already producing cold water, the reclamation system not only saves water, but also, the power is absolutely free, except for the power consumption, in the form of pump costs. Apart from that, there are no running costs.”

THE BACKROOM BOYS Engineers are often the unsung heroes in the cause of energy saving.

Barnett echoes this sentiment when he says: “As engineers, we continually look at new ways of power conservation.” A cost-cutting initiative Barnett introduced in the hotel exemplifies this: changing the electricity steam boilers into gas-fired boilers. “I thus reduced electricity consumption and cost,” says Barnett. “In those days, we did not have the concept of Green Buildings. Such buildings did not exist. But that’s what these initiatives amounted to – water and power savings. We were looking at energy conservation.”

Barnett also introduced the regimen of a yearly thermograph survey, which helped in identifying air leaks. “Through the initiative, we stopped air conditioned air from escaping from the building,”

“In those days, we did not have the concept of Green Buildings.

Such buildings did not exist.

But that’s what these initiatives amounted to – water and power savings. We were looking at energy conservation.”

says Barnett. “It identified installation failures and air conditioning losses.” As a remedy, Barnett and his men installed air curtains and brought costs down.

EVERY ‘PHIL’ COUNTS There was a time in Dubai, when people and businesses used power indiscriminately.

There seemed to be a perennial supply of it, and not many were interested in counting the costs – both economic and environmental.

But everyone was made to sit up and pause for thought when costs began to pinch.

“Early in the 1990s – in 1992, in fact – the price of city’s power increased from 7.50 fils/KW to 15 fils/KW,” recalls Barnett. “It was a 100% increase! It caused people to press the panic buttons, and everybody got onto the energy-conservation bandwagon. Today, it is 33 fils!”

SCREAMING IT FROM ROOFTOPS In 2003, Grand Hyatt opened, and Barnett executed a couple of innovative concepts there.

One of them was a solar hot water project. Barnett elaborates: “It was an idea I had to use the cinema (Grand Cineplex) roof space, which was wide open, and which gets sunlight all day long. And it is adjacent to the hotel’s dieselfired hot water plant. So, by installing solar panels, I was able to produce hot water that was heated by solar energy.”

This is how the system worked, and still does: In conjunction with storage facility, the water was heated during the day and well into the evening, at which point, the diesel-fired boiler took over. “I’m achieving a high temperature, and I need 70ºC to satisfy the internal requirements of the building,” Barnett says. “I have been saving diesel fuel consumption by 33% every year. That’s a heck of a lot of carbon – a gallon of diesel equals 2.7 kilogrammes of carbon dioxide. So, it’s savings in hundreds of thousands of gallons. It is not only a saving on diesel costs, but also a reduction in carbon emissions.”

SPRINGING A SURPRISE Apart from introducing innovative ideas, troubleshooting is another of Barnett’s specialities. The trouble, in this case, sprung in the form of mildew and fungus in the residential building of the Grand Hyatt. “In summer, we received hot and humid air, and we were not able to cool it enough to get the moisture out,” recounts Barnett. “The dehumidification system would have cost us 175KW/ hour in electrical reheating, to dehumidify the necessary fresh air. I overcame this by installing two coils in each

fresh air unit.”

The problem, Barnett figured out, was humidity entering the apartment – an inability to cool the outside air below its dew point. Thus, humidity was being carried indoors, as a result of which, mildew and fungus sprouted.

Design consultants offered conventional dehumidification solutions, including duct re-heating and/or desiccant wheels.

Both solutions would have meant consumption of very large amounts of electricity.

Calculations showed the estimates at 175KW/hour.

Barnett hit upon a simple plan: “My solution was a thin coil placed on the fresh air stream before the chilled water coil, and connecting it to a similar coil after the chilled water coil. A closed loop circulated with a fractional horsepower pump through each coil. This carried outside air temperature – which can reach 45ºC – to the inner coil, when the air passing through it is reheated from 12ºC to 17ºC. This allowed us to cool the incoming air below its dew point, thus expelling all humidity, and then reheating this air using a heat transfer.

This achieved a temperature of 5ºC and solved the problem, with no electrical consumption. I did this four years ago, and have not had a problem since then.”

GOING DOWN THE DRAIN Barnett’s next project at the Grand Hyatt was to install an effluent treatment plant.

“Firstly, I got the city of Dubai to give me a second effluent connection,” Barnett explains. “The Director of Drainage agreed to help supply the effluent to cooling tower make-up water. The effluent has lot of suspended solids and has minerals in it. I installed a treatment

The Hyatt initiative The Hyatt head office has set up a special division for conservation, with its own Vice President, to administer global Hyatt environmental initiatives. Under this, each hotel is monitored and compared electronically. Global reports are issued to gauge their performance, based on overall targets. “We are introducing compulsory energy audits,” says Phil Barnett. “We are given targets, benchmarks, lists of conservation techniques, operational procedures, down to devices, such as timers and motion detectors. All these technologies can save electricity and water.”

Barnett informs that in addition, every Hyatt hotel has formed a green team consisting of representatives from all levels and departments in the building. “We sit together on a monthly basis and talk about our observations and ideas, and where they see savings potential,” he elaborates.

The ideas that emerge from the meetings are highlighted in the minutes and action plans are issued. In addition, the green team’s initiatives are shared by all Hyatt hotels.

Barnett adds: “If someone in some other Hyatt hotel – say, in California – has a good idea, we pick it up in Dubai. Many of the good ideas do not come only from the top management but also from the guy at the operational level.”

plant to filter the particulates suspended in the water.

Secondly, I installed an RO section to remove some of the dissolved minerals by mixing these two waters together. I produced make-up water that was similar in consistency to Dubai mains water.”

The entire exercise had interesting and far-reaching implications. It translated into environmental and economic sustainability.

For one, the city supplies effluent water at a fraction of the cost of mains water.

This means that in summer, the hotel is able to save 100,000 gallons of drinking water a day.

Installing automatic taps and flow restrictors in guest rooms was yet another measure the hotel adopted. Albeit a minor, low-cost initiative, it is still a laudable one.

INNOVATION IS THE KEY Barnett, in keeping with hotel’s policy, is always on the lookout for new ways to cut costs and energy consumption.

So, when he was recently introduced to a hybrid transformer made in South Korea, he put it to good use.

“The South Korean company said that it would save 8-10% of power consumption,” Barnett says. “They offered to install it on a trial basis, at no cost to me. Today, I am happy to say, I have had it running since mid-November 2009, and I get 13-14% average savings in my power consumption every month. I’m happy with the machine. It will pay for itself in one and a half years.

After that, it is a case of clear profits.”

The device, Barnett explains, has no moving parts, and is, therefore, maintenance-

free: “The way it works is that it sits next to the DEWA transformer and balances your power and removes all harmonics. In big buildings with VFDs, harmonics is a big problem in increasing your power consumption. In power, you have a nice, smooth wave.

When you are supplying a non-linear load, another wave comes backwards and causes interference. And to overcome the back wave, you consume more power. This device cleans up the back wave.”

Barnett has taken this innovative experiment a step further: “I showed this device to the DEWA people and told them, ‘This is the future’. It is expensive, but the net result is that you use less power.”

Grand Hyatt Dubai currently has 28 transformers, each 1,500 kVA, but only one of the transformers has been fitted with the device. Barnett is studying the loads of the other transformers so that he can take a call on expanding the use of the device in future installations. “I want to save money and power,” says Barnett.

LIGHT MINUS HEAT To replace the MR16 halogen spotlights in the hotel is another initiative that Barnett

wants to undertake. “They look nice, but cost money,” he says. “They use 50W of electricity. Over 90% of the electricity is dissipated as heat. LED has replaced the MR16. It is similar in colour and intensity, but uses only 7W of electricity, and burns absolutely cool. So no heat is generated.”

This implies that there is less heat load on the building, which in turn, means the air conditioning does not need to be notched up higher to cool the interiors. In the final analysis, not only is there savings in terms of bringing down the energy use from 50W to 7W but there is also a reduction in the heat load.

Barnett is, therefore, understandably in a hurry to get rid of the halogen lamps in the hotel. He says with palpable enthusiasm: “I have 2,500 halogen lamps to be replaced with LED. 50W down to 7W, and no heat!

So electricity load and air conditioning load will come down. Also, the bulbs will have 25,000 hours as opposed to 3,000 hours’ lifetime.

They are expensive, but the payback is six months.

Definitely, LED is the way to go. We are looking at installing them this year.”

WATER – GREY AREAS Another initiative Grand Hyatt Dubai is considering is to install a system to conserve rinse water generated by the laundry system. The rinse water has relatively less soap and no dirt. The good news is, it can be captured and processed through a filtration system and into a tank.

“After that, it is a matter of delivering the water to the machines as wash water – reusing the water many, many times,” explains Barnett. “The rinse water comes back to the machine as wash water.

There is currently fresh water coming in. So that would be 50% savings on consumption of fresh water.”

The hotel also has its sights set on using the building’s grey water – capturing it and passing it through a small treatment plant for coloration purposes and cleaning it. It can be subsequently used to flush toilets. Currently, fresh water is being used for this purpose. Barnett, with one eye on water conservation and another on cost cutting, exclaims, “What a waste of this fresh water! Grey water will save us money and 30,000 gallons a day!”

Barnett believes that the project can easily be implemented, as the hotel building already has a twopipe system in place.

CORPORATE COMMITMENT TOWARDS CONSERVATION Barnet’s personal commitment to safeguard the environment and to cut costs is aligned to that of Hyatt Hotels, which wants to be recognised for its CSR policy, vis-à-vis the environment. The powers that be would like every Hyatt hotel the world over to reduce water and electricity usage by 15% by 2015. “To achieve this, you have to do the kind of things I am doing,” Barnett says. “These initiatives cost money.”

The Wasl Corp, which owns the hotel is aware of

the virtues of retrofitting and embracing new ideas to make the establishment more comfortable, efficient and environmentally friendly.

Barnett endorses this: “I made a presentation to the owning company. They listened to me and accepted the savings potential. They also appreciated the environmental impact reductions. They were pleased that we were leaning in this direction.”

The corporate support has nudged Barnett to push his agenda forward: “Initially, it is a challenge to persuade the owners of any facility, but it depends on how the plan and the vision are presented. It has to be presented properly, and not just the commercial perspective, because in some cases, the ROI period could be long. But the impact on environment is equally important. We are looking at solar lighting technologies.”

But Barnett adds with cautious enthusiasm: “We are investigating; I don’t want to rush. I believe in stringent tests of the technologies, and if satisfied, will go in that direction. If they give lights for only four hours, that is not good enough for me.”

GRAND PLANS With all the groundwork that Grand Hyatt has done under the guidance of Barnett, LEED certification would, perhaps, be the logical step forward. Barnett concedes this and adds: “Hyatt is one of the founding members of the Emirates Green Building Council (EGBC). I am still in contact with Dr Sadek Owainati (EGBC co-founder) – he was the lead consultant for this building, and so he has a soft spot. He is in dialogue with me to turn this into a certified green building. We have to look what it is going to cost us. It is a goal. Certain things we are stuck with, considering it is an already constructed building.”

Case-in point Highlighting regional and global retrofit initiatives

A study in green The newly expanded Johnson Controls global headquarters at Glendale, Wisconsin, demonstrates the benefits of a three-pronged approach to sustainability.

A

growing number of companies increasingly measure their performance using the triple bottom line indicators of economic, social and environmental impact.

Johnson Controls Inc, set out to incorporate these values in the construction and expansion of its headquarters campus in Glendale, Wisconsin.

The company began demolition of parts of the old structure in Fall 2007, and had a grand opening of its new facility in Fall 2009. It will submit an application to the US Green Building Council to receive Leadership in Energy and Environmental Design (LEED) Platinum certification for its new campus, which includes four buildings and the surrounding grounds. The company hopes to receive this recognition.

The 33-acre complex includes 306,359 square feet of new and completely renovated office space. Two existing buildings with a combined 160,000 square feet area were renovated for the corporate headquarters, and three new buildings were constructed – a 114,599-squarefoot headquarters for its Power Solutions business; a 31,700-square-foot building that includes a cafeteria, meeting rooms and fitness centre and a new four-level parking structure for more than 400 vehicles, including space for plug-in hybrids.

BACKED BY EXPERIENCE No newcomer to the green concept, Johnson Controls was aided in its expansion project

by over a century of experience in making buildings energy efficient. A decade ago, its Brengel Technology Center was one of the first LEEDcertified buildings in the world. It also was the very first building in the world to be re-certified LEED GoldExisting Buildings.

This translated into the new corporate campus incorporating geothermal heat pumps, photovoltaic energy, underfloor heating and cooling, skylights and bigger windows to increase the use of natural light to reduce dependence on artificial illumination.

to provide exact design and construction measurements that are shared by all project members. Using BIM made it a more cost-effective project, because it helped avoid costly mistakes that can happen in conventional construction.

TECHNICAL INNOVATION Debbie Vander Heiden, the Johnson Controls on-site project manager, says that other planning technologies were crucial to one particular innovative environmental element of the project – geothermal heat pumps.

The geothermal system relies on the constant temperature of the Earth to help heat or cool the buildings.

Some 272 wells were drilled Commitment to to accommodate a closed-loop supplier diversity system that supplies the heat pumps in the building.

The project includes contracts with Commitment to reduce 35 diverse businesses in an effort to “The heat pumps help the suppliers create green jobs, supplier diversity winter heating costs by build expertise in sustainability, about 29%, versus current and develop the capacity to handle The project includes contracts with other major green contracts.

BUILDING AUTOMATION In a move to integrate the campus under a single system, everything is tied together, using the Johnson Controls Metasys building management system to coordinate all activities across the facilities and provide a single point of access to performance indicators – the information required for optimising building efficiency, comfort and safety.

“The integration of the building systems and the information technology infrastructure into one intelligent network is an important part of our strategy for sustainability,” notes Komorowski, who leads the facilities management team.

“Our Metasys Sustainability Manager provides a dashboard that delivers information, including greenhouse gas emissions estimations, to our management team, who can make informed decisions that save energy and money and help the environment.”

A SUSTAINABLE STATEMENT Johnson Controls is preparing for thousands of people to visit this site in the coming years, to see how innovation and sustainable technology can be combined to yield positive results.

Calling it a showplace displaying a congenial work environment, energy efficiency and facility management initiatives, Komorowski says, “It will be easier for our own customers to see value in this approach, when we can show how well we’re putting it into effect here at home – and how we’re doing it cost effectively.”

According to Johnson Controls, the campus reflects its three global businesses – automotive experience, building efficiency and power solutions – in its drive towards creating a more comfortable, safe and sustainable world.

Retrofit champion Every month, we profile a key personality that is driving retrofitting initiatives in the region

‘Let’s cut the excess flab’

Why should our buildings be so obese? asks Sarfraz Dairkee, adding that it is important to address issues that give rise to retrofit opportunities.

T

o drive home his point about the retrofit market in the UAE, Sarfraz H Dairkee, General Manager – Corporate Development and Engineering, MAHY Khoory, likes to quote Dr-Ing M Norbert Fisch, Institute of Energy Design, Building and Solar Technology (IGS), Technical University Braunschweig, who observed that proper retrofitting of buildings in the UAE can achieve the benefits equivalent of a nuclear power plant, at a fraction of the costs. Dr Fisch made this observation at a conference organised by AHK (The German Emirati Joint Council for Industry & Commerce) in Abu Dhabi, last month.

Likening the extremely high energy footprint of existing buildings to obesity, Dairkee says that retrofitting them would be akin to putting them through dieting and exercise to cut the “excess flab”.

Dairkee blames the “excess flab” in buildings on the market’s penchant for selling products instead of solutions.

The product-centric selling approach that rules the market today is akin to “the fast food culture”, which is marked by instant gratification and an easy-way-out mentality, resulting in people becoming obese and unhealthy; in the same way, we have “obese” structures. The need of the hour, in the case of building design, is a solutions-based

approach, where a pump supplier, instead of blindly selling the pump, will question if a pump is needed in the first place. “Such a change will happen only if the market is willing,” Dairkee says.

Solution development is increasingly an interdisciplinary affair; hence, all the engineering disciplines involved need to interact more closely with one another, which brings us to the concept of building commissioning.

Dairkee points out that commissioning starts by asking the right questions.

“A design charrette can be organised to bring together all the stakeholders for exchange of views,” he says. “When all the stakeholders

Feature

are involved, there is ownership of ideas. As a result, the building project becomes something more than mere drawings and papers.”

In fact, one of the biggest factors behind the overdesigning of buildings is poor communication and interaction between the stakeholders and the specialist disciplines involved, right from concept to occupancy. It is the physical attribute rather than the subtle quality that gets all the attention. Often, the means for measuring and verifying quality and performance are not available, so the same gets attributed to certain brands or points of origin. “In the end, you limit yourself to the small picture,” Dairkee says.

Also, asking questions can help owners define their project requirements, understand quality better and ensure smooth communication with other stakeholders. The objective is to move beyond the gross in order to get to the subtle. “Defining your requirements in terms of ‘a beautiful glass building’ or ‘so many square feet area’ are examples of the gross or the superficial. Instead, you must probe deeper and find out why you need so much square feet or why you need glass?” said Dairkee.

contains detailed information about the building’s energy consumption. Moreover, in many EU member countries, an energy passport is required before any new project can get a building permit.

Dairkee says: “What you get is a measurable and verifiable document, which can be used for benchmarking. We can have something similar in this region, too. The data

It is the physical attribute rather than the subtle quality that gets all the attention. Often, the means for measuring and verifying quality and performance are not available, so the same gets attributed to certain brands or points of origin.

A clear method of benchmarking, too, needs to be adopted; the classic example of a benchmarking tool is the ‘Building Energy Passport’, used widely throughout Europe. Under an EC Directive, all buildings being constructed, rented or sold must have a valid energy performance certificate, known as an ‘energy passport’, which

it provides can serve as a navigation tool by telling us where we stand today, so that we can decide where we want to go. My past stint in the Merchant Navy taught me that if we didn’t have such markers, we are not going to reach our destination, no matter how hard we pushed the engine.”

Can local standards be a panacea where the

challenge of over-design is concerned? To the extent, they truly incorporate local environmental conditions, local standards can be beneficial. “Unfortunately, the prevalent idea is to control the environment, instead of working with it,” Dairkee rues. He likens the difference between the two to hitting the bull’s eye using a machine gun versus using a rifle armed with a single bullet. The ‘machine gun’ approach results in everybody designing and piling on safety factors, which ultimately culminates in an ‘obese’ design. “Design factor is ignorance factor,” Dairkee says. “Larger the design factor, higher the ignorance.”

The way out of this ignorance, he continues, is “learning to unlearn” and “getting out of conditioned thinking, which computers are more adept at”. He suggests Zen and the Art of Motorcycle Maintenance by Robert Pirsig and Small is Beautiful by E F Schumacher as must-read books for today’s engineers, who more often than not, have to work at the interfaces of different disciplines. “What these books teach you is get out of the arrogance of knowing,” Dairkee says. “There is always something new to learn; there is always a better way of doing things, even if they were done well the first time around.

The answers don’t reveal themselves easily, but if you are determined, they can be found.”

Walking the talk Among Dairkee’s memorable projects was the development of a refrigerator running on bio-gas in the 1980s when working for the Indian HVACR engineering solutions provider, Voltas. The asking price for technology transfer from Europe was too high; equally high was the scepticism about developing such a technology in-house in India. Armed with technical literature “gathering dust” from the corporate library and a vapour absorption refrigerator from the local junkyard, Dairkee set out to prove the sceptics wrong. His persistence won supporters from an unexpected quarter – the company’s highly unionised workforce, a few of whom would join Dairkee after factory hours to work on the project without monetary compensation, something dismissed as impossible in those pre-liberalisation days. “When the refrigerator finally produced ice at the end of one very long day, each one of us was literally in tears, as all the hard work and effort had paid off,” Dairkee says. As head of testing in Voltas, Dairkee undertook the difficult task of teaching himself FORTRAN programming language, so as to develop a simulation programme for testing the air conditioners manufactured by the company.

S

cientists are, by nature, questioners and doubters. So, when you see most scientists agreeing on something, it is time to take note. With this as the warning bell, and Albert Einstein’s dictum that “We can’t solve problems by using the same kind of thinking we used when we created them”, the resource person, Sougata Nandi, Director of Sustainability at TECOM and ENPARK, conducted a two-day workshop, titled, ‘Profitability through Sustainability’. It was held on May 5 and 6 at Knowledge Village, Dubai. The participants included employees of Dubai Municipality, DEWA, Dubai Chamber of Commerce, RTA, KHDA, the Royal Estate of the Sultanate of Oman, Trane, Siemens, EMAL and Dubai Police.

The avowed objectives of the workshop were to enable trainees to: • Understand the key components of a sound approach to sustainable development • Define sustainability in the context of their own organisation • Define their organisation’s short, medium and long-term goals • Come up with an implementation plan

The workshop was divided into four modules: Module 1 Introduction • Objectives of the programme • Global trends in sustainability • Local trends in sustainability • Review of delegates’ concepts, experiences and exposure to sustainability Module 2 Components of sustainability • Define sustainability • Sustainability elements as tools for enhancing profitability • Why corporate houses should embrace sustainability • How sustainability blocks recession and fights economic downturn • Implementing sustainable development effectively within an organisation • Case study Module 3 Energy and water conservation • Implementing effective energy and water conservation programmes • Organisational maturity matrix • Rate your organisation • Energy auditing methodology

Module 4 Building green • Why build green?

• How to build green and green building criteria • Site sustainability • Water conservation • Energy efficiency • Energy auditing methodology • Role of energy manager • Implementation strategies • Components of energy and water conservation • Tools required • Measurement and verification protocols • Ascertaining energy bills – normalisation • Energy efficiency • Materials and resources • Indoor environmental quality • Lighting • Light pollution • Lighting power densities • Energy modelling • HVAC load calculation • Ventilation standards • Regional material quantities • Performance contracting • Exercise – define your relevant green criteria set • Stakeholder engagement • Case studies

Nandi employed a combination of case studies and demonstration of frameworks to drive home the issues.

MODULE 1 – INTRODUCTION

Starting with what appeared to be simple, even simplistic definitions, Nandi took the delegates through the paces to the more complex and axiomatic issues of global warming and climate change.

He cited statistical data to support his point regarding urgent need for action: The Earth is warmer now than in the past 1,000 years. The average surface temperature has risen from 0.6°C in the past century to 0.75°C, since pre-industrial times, thanks to greenhouse gases and pollutants like carbon dioxide. We are releasing more and more CO2 over time – 1,000 years of CO2 and global temperature change has increased the level in the atmosphere by more than 35%, since the Industrial Revolution.

(National Oceanic and Atmospheric Administration 2006). The 1990s were the

warmest decades since 1861, when thermometer records began. The year, 2006 was the warmest year on record. The temperature increase in the 20th century was the largest of any century in the last 1,000 years. The 10 hottest years since the beginning of the last millennium have all occurred since 1983.

A few of the many signs of climate change Nandi listed were: • Melting Polar ice • Melting glaciers • Increased hurricane activity – in 2005, most Category Five hurricanes occurred in the Atlantic Ocean • Heat Waves – the 2003 heatwave killed at least 35,000 people in Europe • Rise in sea level – 100 million people live within 100 centimetres above the sea level

cover story rise of sea levels was anticipated by 2100, Nandi made a case for global responsibility, corporate action and sustainable development policies in the region.

Following were a few of the examples cited of sustainable policies in the region, backed by corporate will: • Dow Chemical reduced energy per unit of production by 21% since 1994, saving $3 billion.

• 3M reduced emissions by about 37% between 1990 and 2004, by reducing energy consumption by 4% per year.

• BP reduced emissions by 14% between 1998 and 2004, gaining $650 million.

• TECOM Investments reduced electricity and water cost by US$7 million in 33 months and CO2 emissions by 38,000 tonnes.

WHY BUILDINGS?

The spotlight on buildings as environmental culprits yielded the following facts: If we take the United States, as an example, buildings are responsible for: • 12% water use • 30% greenhouse gas emissions • 65% waste output • 70% electricity consumption (Source: USGBC)

It was noted that in Dubai, commercial and residential buildings currently consume 85.5% of the Emirate’s water and 73.8% of its electricity.

(Source: DEWA) Buildings, therefore, have a huge impact on the environment.

SUMMING UP – MODULE 1

The session concluded on a sombre note: It is evident that climate change is a reality, though the extent of its impact may be subject to debate. Immediate action, therefore, needs to be taken to mitigate its impact. Since buildings are one of the major contributors to climate change, effective action needs to be taken in this sector.

MODULE 2 – COMPONENTS OF SUSTAINABILITY

Under the rubrics of components of sustainable development, Nandi said that sustainable development can add commercial value to a building, but in order to implement it effectively, consistently and sustainably, one needs to have a clear understanding of two diverse paradigms: projects hierarchy and the traditional design and construction process.

A sustainable collaboration work model was presented with a view to minimise environmental impact caused by development, while sustaining lifestyles within the carrying capacity of the planet. They included: education and training; advice and consultancy; finance partnerships; business building and research and policy.

Taking stock of the current situation, Nandi analysed the key areas for consideration and their implications as: 1. Explosive economic growth: Implication – strain on energy infrastructure

and financial burden 2. Burden on energy resources to multiply in the years to come, in some cases by three times: Implication – bigger resource-saving opportunity 3. Many cities/countries in the region lack representation at national and international level on sustainability-related areas: Implication – lack of profile 4. Several regional visions address sustainability: Implication – need professional implementation 5. Random initiatives on SD by

multiple parties: Implication – lack of cohesion Conclusion: Streamlined thrust on sustainable development required at all levels. A two-pronged strategy was recommended at both the high level and the macro level: • Support sustainable community and building development • Support with LEED certification for construction of new community developments

5) Supporting with policy development and recommendation of policy initiatives 6) Hosting business forums on select renewable energy/ sustainable commercial development topics

Majid Khalfan Khalfan, KHDA

Nandi concluded that a holistic understanding was the key to individual stakeholders contributing effectively to the cause.

POLICY COMPONENTS

While a sustainable development policy is a must, in all probability it will vary from organisation to organisation. Factors that are likely to dictate the key elements of a sustainable development policy are: • Nature of the business • Areas of focus CSR component • Level of top management commitment

POSSIBLE KEY INITIATIVES:

1) Increasing public awareness 2) Supporting government initiatives 3) Facilitating business building and networking 4) Developing green awareness through education curriculum for schools

SUMMING UP – MODULE 2

Nandi summed up the module by concluding that sustainable development means different things to different people. It is, therefore, necessary to identify what is important for people and their organisations, and pursue their goals systematically and sustainably.

He also listed the perceived business benefits of building green: 1) A 7.5% increase in the building value 2) A 6.5% improvement in investment returns 3) A 3.5% increase in occupancy ratio 4) A three per cent rent ratio increase 5) A 8-9% decrease in operating costs

MODULE 3 – ENERGY AND WATER CONSERVATION

With the dictum, “Begin with the end in mind”, Nandi discussed the following issues in this module: • Identification of energy saving measures • Performance contracting • Measurement and verification • Benchmarking energy consumptions • Sources of inefficiency/ wastage • Inefficiency/wastage is one of: – over-designing – lack of controls – inappropriate use (what should be used where) – old technology – human error and insensitivity Nandi was concluded that all these factors can be identified and redeemed.

SUMMING UP – MODULE 3

Nandi summed up the module with the following observations: • Water-conservation techniques are the most easy to implement • Payback periods are faster than electrical measures • The best way to save water is by appealing to commonsense and raising awareness • Reducing potable water consumption and recycling waste water The goals, Nandi said, could be achieved through a clear 30

objective, the right approach, a thorough understanding of the system, and by involving all the parties concerned.

MODULE 4 – BUILDING GREEN

Under this header, Nandi listed a few pre-conceived notions about green buildings and helped dispel them: 1) Building green costs extra money 2) LEED is only for the United States 3) Project timelines too tight 4) We have other priorities Nandi posed the question: Why build green? He, then, enumerated with supporting authentication, what a green building can help reduce: 1) Energy use by 24%-50% 2) Water use by 40% 3) CO2 emissions by 33%-40% 4) Solid waste by 70%

While a sustainable development policy is a must, in all probability, it will vary from organisation to organisation.

In this context, a look at a Dubai factsheet revealed that buildings in Dubai consume 72% of electrical energy and 83% of water generated, which in itself is a cause for concern.

In the following sessions, aided by case studies from LEED projects in Dubai, Nandi informed participants about green features, how to certify green buildings on the basis of mandatory prerequisites and credits and about how LEED works.

Nandi emphasised that the key factor for any successful LEED project was instilling an integrated project team, right from the conceptual stage of the project. He familiarised the participants with the key ingredients: • Integrated project team • Early involvement in contract negotiations • PMP approach • Fit-out guidelines • Senior management support • Personal commitment The session also looked at an oft-neglected green feature

– light pollution reduction.

The avowed intention, said Nandi, was to minimise light trespass from the building and site, and reduce sky glow to increase night sky access.

Moving on to the issue of achieving water efficiency, the participants took a look at ways to minimise water demand.

• Ultra-low flow fixtures • Ultra-efficient flush tanks • Sensor controls • Utilising free water • AC condensate It was concluded that the goal should be to maximise water efficiency within tenant spaces, and to reduce the burden on municipal water supply and wastewater systems. Nandi noted that as part of TECOM’s ongoing energy- and waterconservation programmes, since April 2007, cost-effective conservation measures have been implemented. Even before the LEED certification

process had started, Nandi said, all buildings were fitted out with water restrictors, which helped reduce TECOM’s overall water consumption by 26,232 million gallons, between January and December 2008.

In the session, Energy and Atmosphere, Nandi asked the trainees to take a closer look at prerequisites and credits: Prereq 1: Fundamental commissioning of the building energy systems Prereq 2: Minimum energy performance Prereq 3: Fundamental refrigerant management Credit 1: Optimise energy performance Credit 2: On-site renewable energy Credit 3: Enhanced commissioning Credit 4: Enhanced refrigerant management Credit 5.1: Measurement and verification – base building Credit 5.2: Measurement and

SUMMING UP – MODULE 4

Nandi summed up the session with the following observations: • LEED is just one of the many frameworks to be utilised as a tool to make your building green • LEED works very well in the GCC – there are many examples of successful LEED projects • There are many different ways to make a building green – prioritise and see what is important • Do not set LEED Platinum as a target – it is neither necessary nor relevant • Building green helps all stakeholders, including infrastructure service providers After going through the rigours of training, the workshop was perceived to be useful by all the delegates, as they got an opportunity to arm themselves with tools to implement sustainability programmes in their own departments/agencies.

On a slightly tangential, but relevant note, the Dubai Chamber of Commerce and Industry achieved LEED certification for its building in Deira. The real benefit of this, is, of course, power and 32

water saving. TECOM through its water- and energyconservation drives has been able to achieve $7 million in savings in 33 months. This is an audited figure, and is a positive sign of the shape of things to come in the country

and the region. It will not, perhaps, be too unwise to hope that nudged by both responsibility towards the environment and financial benefits, the construction sector will channelise green into the mainstream.

perspective

Cool solutions to towering problems Aslan Al-Barazi takes a close look at different types of cooling tower separators and filtration equipment to demonstrate how to maximise the efficacy and efficiency of cooling systems.

INTRODUCTION: TOWERS AS AIR WASHERS “Air wash” technology in humidity control systems is little more than a modified cooling tower. As such, cooling towers clean all the dirt in the air going through the system, leaving the discharge air upwards from the tower pure and clean. Therefore, in addition to providing efficient heat removal through evaporation, a cooling tower doubles, often unintentionally, as an effective air washer.

Airborne particles such as pollen, mould spores, sediments, sand and dust are absorbed or trapped by the water droplets falling through the cooling tower.

The particle-laden droplets merge with the bulk water supply and are carried into the piping and through the chiller condenser heat exchanger before circulating repeatedly as part of the bulk water flow. The heaviest particles – those with a specific gravity greater than that of water – tend to settle in low-flow areas of the 34

system, such as in the cooling tower basin. Other particles are trapped on the tower fill, and still others are bound to heat transfer surfaces through the formation of scale and “biofilim”, when water is not adequately treated.

HAZARDS OF DIRTY WATER Particles that are lighter than water, such as pollen, add to the biological loading of a cooling system. Organic matter becomes food for colonies of bacteria, leading to a degradation of water quality. If left in the water system, such organic matter contributes to masses of bacteria, in what is termed “biofilm” – a slimy layer of bacteria colonies excreting enzymes that feel “slick” to the touch. A layer of biofilm as thick as a human hair can reduce system heat transfer efficiency by upwards of 20%.

To make matters worse, heavier sediments that settle in cooling tower basins are also prime breeding ground for bacteria and underdeposit corrosion, which can shorten the lifespan of

capital equipment. Biofilm on both heat transfer surfaces and beneath tower deposits tend to resist corrosive biocide chemical shocks, as only the surface colonies are killed before the rest of the colony regenerates. In fact, many waterborne bacteria populations double every 20 minutes in prime, warm water conditions found in cooling towers. Thus, organic loading severely degrades water quality and system performance.

The location of a cooling towers and the prevailing season are, of course, two significant factors in total particulate loading of a system. Pollen-producing trees and shrubs, sandstorms, and even nearby local construction with concrete cutting, can all pose major challenges for cooling towers, which will ultimately scrub the nearby air.

The origin of particles found in some towers has been traced to locations more than five miles from the site of the tower, as prevailing air currents carry airborne matter. If not properly treated, over time, the cooling tower’s

sensitive areas such as the cooling tower PVC fill, internal water piping distribution system, chiller condenser heat exchanger, and especially pump seals, experience abnormal wear and tear. Small, dense particles, such as sand, can act like abrasive sandpaper on system components.

Larger particles, such as leaves and scale chips, can clog intake screens, obstruct water paths, and begin to reduce heat transfer efficiency and capital equipment lifespan, leading to increase-related maintenance costs, operational costs, downtime maintenance cost, and ultimately the Life Cycle Costing (LCC) analysis.

Indeed, even concentrated minerals in makeup water, such as calcium carbonate and silica will naturally conglomerate and settle down over time, based on spikes to total water conductivity, water PH, alkalinity, and changes to other significant water quality parameters.

Particulate matter in system water becomes a bigger issue than a chemical service provider is often able to tackle. So, what is an owner/ operator to do?

While chemical treatment is helpful in controlling the increased concentration of dissolved solids in the water, and can be an effective deterrent for biological growth, such treatment does nothing to handle the undissolved solids running through the system. For the above-mentioned reasons, it is especially important to remove from the bulk water supply particles visible to the naked eye – about 40 microns in size and larger.

More expensive micro filtration used to remove particles below five microns, while advantageous to overall system cleanliness, is often cost-prohibitive. As such, inexpensive water filtration, in the form of sand filters or centrifugal separator systems are designed with larger particles in mind, and are particularly helpful in controlling total particulate loading on a tower, without excessive additional energy cost.

Ironically, while most customers ensure they filter the air flowing through their air handling systems, many of them neglect to filter the water through their more capitalintensive cooling systems.

More to the point, the subject under discussion here is the different approach or design a client may opt for when considering the use of

either a cooling tower separator or sand filter system. Full stream separators, side stream separators, basin sweeper system and sand filters are the primary options.

What customers need to consider are cost-effective solutions to enhance heat transfer efficiency and reduce liability to waterborne diseases such as Legionella.

There are, of course, advantages and disadvantages that come with each option.

These options are explained:

CETRIFUGAL SEPARATORS AND SEPARATOR SYSTEMS Full stream separators rely on a separator located after the condenser pump which

filters 100% of the water flow and separates up to 97% of particles sized 40 microns and higher in a single pass. Separators succeed through their use of centrifugal velocity, baffles, and solids capture systems in a selfcontained and fairly simple design. Utilising an automated blow down through timed purge valve, takes the guesswork out of purge frequency.

The downside of this design is the extra head loss (between 5 to 9 psi), which needs to be accounted for on the frontend in engineering design calculations. The tradeoff for the use of slightly more pump is a significantly cleaner and safer system, and a preservation of capital

perspective equipment. Customer payback on filtration systems is typically less than 24 months, when all factors, including maintenance, energy savings, and water savings of the overall tower and cooling system are considered.

Side stream separators are the most popular filtration systems in the industry. Normally, designers incorporate eight to 25% side stream of the total cooling tower flow rate. For example, a design flow rate of 2000gpm through a common header would enable the customer to downsize the total filtration skid package to, say, a 400gpm unit, with its own pump and automated solids purge system.

An effective side stream filtration system includes a well-designed basin sweeper system to properly agitate settled solids in low-flow areas of the system, such as the cooling tower basin. From a

cost comparison standpoint, it is interesting to note that full stream filtration can be significantly more expensive than side stream filtration systems, when comparing direct capital cost. But when added energy input for side stream pump operation is factored into the equation, the energy input required to run the small side stream pump makes the side stream slightly more expensive than it might first appear.

Another factor to consider when deciding between full flow separators and side stream separators is the role of blow down. Options exist for zero bleed where continuous purge through a bag filter returns the clean, filtered water to the tower. A recovery tank necessitates manual cleaning of the bag filter but ultimately saves water. This type of solid capture system can be particularly effective with closed-loop, nonevaporative systems.

It should be noted that whether a customer uses full stream or side stream separators, the bulk water supply will effectively be treated, leading to a reduction in overall system fouling. However, many heavy particles will settle quickly in low-flow areas of the system, such as in the cooling tower basin. Unless those particles are carried to the suction header, they will build up over time, increase biofouling and the likelihood of underdeposit corrosion, and potentially set like concrete, if the natural minerals which settle out from the water are left to adhere.

A pragmatic approach to cleaning tower sumps, therefore, is to use a specialised cooling tower aquatic vacuum cleaner, which is an inexpensive device. Regular manual cleaning, however, can significantly add to the overall operational cost of a system, when tower basins are particularly large.

THE PROS AND CONS OF BASIN SWEEPER SYSTEMS A more effective alternative to aquatic vacuum is a welldesigned basin sweeper system.

In the same way as ozone systems were enthusiastically implemented on cooling towers in the 1990s, and then, subsequently, created significant corrosive tower breaches and failures, basin sweeper systems have also been viewed by many in the industry through a “love it” or “hate it” lens. The reason for the wide sway in opinion comes down to application: in the same way that ozone systems work well if the design is accurately balanced, so too, do well-designed sweeper systems – they effectively remove tower sediment. When correctly applied, they lend themselves to a tremendous simplification in operation.

Geographical considerations, total exposure to fouling, and prevailing weather conditions give credence to the notion that design of an effective basin sweeper system becomes even more important. This is especially true for towers located in the UAE. Consider the following: A) Given the aggressive sand, dust and haze conditions in the UAE, 10% side stream (for the sweeper system), as most designers incorporate for their local systems, is generally insufficient for effective sediment removal.

Griswold & IMEC have confirmed that a higher treatment ratio – often beyond 20% side stream – leads to successful filtration.

B) In a competitive market requiring cooling towers to be “low in height” (low profile), to reduce visual disturbance for people living in the vicinity, this would also mean that the tower basin heights would normally be correspondingly shallow. Likewise, basin water level is also often low.

Thus, there is a need to take special care when considering the issues confronting the

Cool solutions to towering problems

condenser pump operating at minimum static height levels such as NPSH of the pump, vortexing, and any extra air going through the pump, where cavitations is a risk. A properly designed sweeper system will churn the water slightly, to literally “sweep� the particles towards the tower suction header/s for separator removal. Thus, appropriate caution and necessary design parameters must be used in selecting effective head pressure and system layout.

C) Hydraulic design responsibility of basin: concrete cooling tower basin common in district cooling plants are not normally in the scope of the cooling tower manufacturer, because they are normally built by the civil contractor.

Design responsibility needs to be decided in advance during the design stage.

The question is, will the consultant, civil contractor, MEP contractor or cooling tower manufacturer handle the design scope responsibility? The design scope needs to be accounted for and addressed during the design stage of the project, so that no confusion arises later on about who is doing what is in terms of related scope.

Basin sweeper systems may make this design responsibility burdensome for those who might prefer a simpler and a more pragmatic approach (like a side stream separator with aquatic vacuum cleaners, for example), while others would prefer a more sophisticated maintenance-free approach, like a sweeper system.

D) Basins range in shape and design between crossflow to counter-flow towers, for example to concrete basins in industrial applications (with different shapes and designs, as well). It is, therefore, highly recommended that the design be based on a specific cooling tower basin

In cases of result in significant water extremely large basins, loss during automated purge switching valves can be used cycles, whereas, an automated to modulate flow from one separator purge system that set of sweeper nozzles to the drains to sewer will blow down next, effectively creating a up to 95% less water.

system is a relatively small price to pay for extending the life of capital equipment, reducing system fouling, and maintaining heat transfer efficiency. For a pragmatic and simple approach in optimising water system effectiveness, and for one that contributes to maximising effective, costefficient water and energy use, side stream or full stream separators, combined with a properly designed basin sweeper system or manual aquatic vacuum cleaners can create a reasonably short return-on-investment and reduce the headaches of systems operators everywhere.

SAND FILTERS Sand filters are another option for effective removal of solids. The challenge with sand filters, however, is that in our aggressive environment, with significant particulate loading, sand filters need to be constantly maintained to ensure the media bed is properly fluidised. Undersized systems can foul quickly, and leave little tolerance for heavy sand storms. Without proper maintenance, sand filter beds can become impacted, resulting in the loss of media and significant downtime.

While sand filters can be more effective in removing smaller particles (down to 5 microns, for example) their larger size can make placement cumbersome.

Some sand filter manufactures use fibreglass or composite materials to provide a less expensive product to customers. But some of these materials are not UV-resistant. More to the

tenders & projects Period 10/06/2013 Remarks This project calls for the supply and installation of gas

injection compressors, treatment units, separators, four 20-kilometre pipelines and related facilities at the onshore Arzanah site. The scheme will involve re-injection of 10 million-cubic-feet-a-day of associated gas to maintain reservoir pressure at the offshore field.

Client will tender three main construction contracts on this scheme. A tender for the main construction contract to build offshore facilities, and upgrade existing facilities and pipelines will be issued soon. The water facilities will separate crude oil from water produced by reservoir before transporting both to processing facilities at Zirku Island using an existing 58-kilometre main oil pipeline.

The main EPC deal comprises both offshore and onshore engineering, as well as construction work, and is worth some $250 million-$300 million. The winning bidder will have to build a series of underwater pipelines and upgrade existing offshore platforms at the field.

Five engineering firms have submitted technical bids for the project management consultancy (PMC) contract to oversee the EPC contractors. Bidding firms include UK’s Mott MacDonald, AMEC; US/Canada-based Veco; Canada’s SNC Lavalin; and Norway’s Aker Solutions.

17,000,000,000 This project is in Saudi Arabia and will be one of the largest industrial projects ever undertaken. The development will be known as Ras Tanura Integrated Project. Downstream process units will include 400,000 t/y of propylene capacity, an aromatics complex to produce 400,000 t/y of benzene and 460,000 t/y of paraxylene and a speciality mix of purified terephthalic acid (PTA), polyethylene teraphthalate (PET) resins, toluene di-isocyanate (TDI) or methyl diphenyl-diisocyanate (MDI), SBR or ABS resins, and acrylonitrile (ACN). This complex will also have a business park to promote the local plastics conversion industry. Client has decided to relocate this project to Jubail Industrial City on the Gulf coast. As a result of this move, the joint venture partners are planning a huge change to the scope of this petrochemicals complex. It will now be fed entirely by ethane and propane gas rather than a mix of gas and the petroleum product naphtha as was originally planned. The ethane and propane will be provided

by Saudi Aramco Total Refining & Petrochemicals Company (Satorp). Front-end engineering and design (FEED) studies for the reworked petrochemicals complex are due for completion by the end of 2010. EPC contracts could be tendered in 2011.
