The notions of sustainable design and energy efficiency first entered global consciousness following the energy shortages of the 1970s and 1980s. Influenced by ideas of energy independence, many designers in Europe and North America sought ideas and strategies that could help create energy-efficient buildings and cities. As they searched for design solutions, some researched the environmentally responsive elements of traditional architecture, while others developed new solutions that employ modern technologies and high performance materials.
As the energy crisis subsided, the building industry in North America returned to business as usual, allowing its European counterpart – which emphasized technological solutions – to take a lead. But with the revival of global interest in sustainability – this time driven by both environmental and energy concerns – the dormant dialogue between the two approaches to sustainable design returned to play a role in shaping the global sustainability agenda. Oscillating between advocates of passive design and proponents of technological solutions, this dialogue continues to enrich the discourse on the future of sustainable design and development
National Commercial Bank in Jeddah (left). consists of a triangular 27-storey office tower juxtaposed with a six-storey, 400-car circular garage. The verticality of the bank tower is interrupted by three triangular courtyards ‘chiseled’ into the building's facade. The office windows are oriented towards these courtyards with an inward orientation typical of Islamic traditional design. This provides the interiors with daylight but prevents them from overheating. Copyrights: Wolgfang Hoyt/Esto.

During the 1990s and the early 2000s, the UAE, and the city of Dubai in particular, witnessed a rapid rate of growth in its built environment driven by a real estate bubble. In the span of a few years the city’s unprecedented rate of growth, which was driven by both demand and speculation, completely transformed the city. But such growth came at a price. Driven by their need for quick returns, developers cared little beyond delivering a building on time and on schedule. Speed of construction often came at the expense of quality, and issues of performance and energy use played almost no role in the design and construction processes. Common disregard of performance was also fueled by the fact that most buildings were commissioned for developers – rather than owner/occupier clients – since their focus lied solely on reducing initial capital expenditures without considering operating costs that are typically borne by tenants.

These commercial forces, coupled with relatively cheap electricity across the UAE, and a lack of demanding building regulations have paved the way to the development of unsustainable design practices over the last decade. A typical office building in the UAE today is a predominantly glazed high rise tower. Basic design decisions such as orientation, massing, and envelope design are usually made without much regard to their impacts on the buildings’ energy performance, and passive cooling strategies are rarely considered.
