Greening the Gulf

Ellen Lammers | August 04, 2009

In Dubai the scale of building construction is staggering. But progress should not be at the expense of sustainability. Thom Bohlen of the Middle East Centre for Sustainable Development talks about how research can help promote green development practices.

The Gulf States are notorious for luxurious lifestyles and generous use of cheap petrol, and hardly seem likely proponents of 'sustainability'. Is this a fair view?

The per-capita ecological footprint of the United Arab Emirates (UAE) is 9.5 hectares, nearly four times the global average. With its growing demand for water, fossil fuels and building materials, Dubai is indeed one of the world’s major consumers of resources. But you will be pleasantly surprised about the number of green buildings that are under construction here. In fact, in October 2007, Sheikh Mohammed bin Rashid Al Maktoum, Prime Minister of the UAE and Ruler of Dubai, issued a resolution stating that all owners of residential and commercial buildings and properties in the emirate of Dubai must comply with the internationally recognized environmentally friendly building standards.

This ‘green decree’, which took effect in January 2008, has enormous implications when you think of the amount of high-rise construction going on here. About 15% of the world’s cranes are located in Dubai, although the current economic recession has put most iconic projects and about a quarter of all other ongoing development projects on hold. Not all contractors and developers enthusiastically embraced the decree. Some buildings had already been fully designed, and the plans had to be revised in order to comply with the new green building rating system (based on LEED) established by Dubai World, one of the Dubai government’s investment arms, as well as to adhere with the decree. When things happen here, they happen fast.

What triggered this ‘green decree’?

We like to think that the decree was somewhat influenced by the development of the headquarters for Pacific Control Systems, a global leader in automation solutions. This office building, which opened in the fall of 2007, was the first green building to receive a platinum rating in the UAE, and at the time was one of only 16 buildings in the world to earn this top rating. It drew the attention of the Sheikh and members of his government, some of whom attended the grand opening ceremony.Sheikh Mohammed has a keen interest in dealing with the climate change crisis, and his resolution is in keeping with the Dubai Strategic Plan of 2015, which he initiated to maintain economic growth and make Dubai an iconic city, and a major tourist destination. But also, I think that the Sheikh has seen the writing on the proverbial wall. At some point in the not-too-distant future, Dubai’s oil reserves will be depleted, and the city will need new economic engines. Sustainability is also seen as another way to make Dubai a unique and modern city, one that is in tune with the times.

Both the Middle East Centre for Sustainable Development (MECSD) and Pacific Controls are currently headquartered in this unique crescent-shaped building. It consumes 35% less energy and 40% less water than the average non-green building. For air conditioning, we have installed onsite a solar thermal cooling system that utilizes a large ground-mounted array of solar thermal panels and an absorption chiller. Solar photovoltaic (PV) panels on the roof generate 50 kW of power for all of the office lighting. We also have an onsite sewage treatment plant, and the ‘grey’ water it produces is used for landscape irrigation and for washing vehicles. The platinum ranking is also based on the use of regionally sourced building materials, and materials with a high percentage of recycled content. Plus we have ‘green label’ carpets and ‘green seal’ paints, and we even use eco-friendly cleaning products. Our building systems are measured, verified and monitored in real time by the Global Command Center on the third floor, through an integrated and interoperable IP backbone. But the best thing about this building, in my opinion, is the use of natural daylight, which gives this office a uniquely high level of comfort for those of us who work there.

What is the scope of the work of MECSD?

Thanks to the ‘green decree’ the centre has grown into one of the largest independent sustainable consultancies in the world. We have expanded our services to include sustainability and carbon management for corporations and other agencies. Our 26 accredited professionals for the LEED certification programme guide our clients through the full process of sustainable building and certification. These clients include multinationals, commercial developers, national and local governments and utility firms. Although many of our staff are architects and engineers, we don’t actually design buildings. Instead, we advise on how to incorporate all the sustainable features into the building process.

We are currently involved with 180 new building projects here in Dubai, which cover an area of 30 million square feet or about 667 soccer fields. But we also go into existing buildings and implement energy conservation measures, which can be as simple as adjusting air conditioner settings in common areas or exchanging incandescent light bulbs with more energy-efficient ones. Or they can be more involved, such as making the heating, ventilation and air conditioning (HVAC) equipment more efficient through energy audits and implementing various energy saving measures. In this respect we’re really facility efficiency experts.

One massive leap forward in creating a sustainable style of living has been the automated systems that Pacific Controls design and install in homes and commercial buildings. These systems measure, monitor and manage energy consumption in real time. Such a system at home can connect all your appliances and building systems and allow interoperability. For instance, you can turn on your air conditioning before you leave work so that you don’t need to keep it running all day, but can still enjoy a cool house when you get home – not an indulgent luxury when outside temperatures are up to 44 degrees centigrade.

What challenges do you encounter in your work and how could research help address them?

There is one way research could help that is actually very practical. For the green development occurring here in the emirate of Dubai, we need economic research into how to improve the market situation regarding the availability of green building equipment and products. This market is not yet competitive, and we are encountering problems with obtaining green products that are much more readily available in the US and Europe, such as energy-efficient heating, ventilation and air conditioning equipment. We educate local suppliers, and even distribute lists of green materials suppliers to our clients. But more insight is needed into what economic barriers need to be overcome in order to create and develop a proper and prosperous green market.

What else is high on your list of priorities?

Sustainability is, for lack of a better word, a new paradigm. It’s becoming a necessary way of life on the planet. But to my knowledge very few studies are being conducted into what the social repercussions are and how living sustainably will affect people’s lives. One approach would be to study how people use and interact with sustainable buildings. Human behaviour is unpredictable, and as an architect I’m often surprised by how people actually use the facilities I design. Knowledge gained in a study like that would help provide valuable information to help project teams to design even better sustainable buildings in the future.

But there’s more to it. Looking at the pace of sustainable development here in Dubai – illustrated also by Masdar, the zero-carbon footprint city that is currently being built from scratch just outside Abu Dhabi – you realize that there will be many transitions for our society in the coming years. This so far has been a phenomenal experience for me, and I feel privileged to be part of this grand transition. But these sustainable community projects provide exciting opportunities not only for technical experiments, but also for sociological research. How will people experience living in a utopian green city, how will it affect their quality of life, their relationships, and the next generation that grows up there? I don’t see much written on this subject, but with the cloud of climate change hanging over us, our children and grandchildren, I think these are very important and interesting social questions that need to be tackled.
