Abstract
On-going development in many parts of the United Arab Emirates has
consequences on the urban environment. The use of glazed facades in modern
buildings has come with an increased operational cost due to the higher solar
gain. However, such strategies have increased in popularity mainly in the local
building industry. Thus, improving the ecological performance of buildings and
minimizing the impact of urban development on the natural environment are the
main concerns for developers and stakeholders in the country at present. These
goals have been acknowledged by national and international architectural firms
and building developers such as Foster & Partners, Creative Kingdom and
Mirage Mille; which have been incorporating ecological and sustainable
approaches in significant projects such as Masdar City in Abu Dhabi, and
Madinat Jumeirah in Dubai, where various concepts and techniques have been
used to promote energy-efficiency in the buildings and avoid increased cooling
loads. The use of passive cooling techniques including natural ventilation,
thermal mass, shading devices, and responsive landscaping have been adopted in
significant projects to maintain the new vision of the country towards building
sustainability. Other cooling techniques such as green roofs and green façades
have also been practised recently in a number of projects across the country.
This paper investigates alternative passive strategies for reducing energy
consumption in contemporary building design and construction in the UAE. Four
techniques are examined in the study: natural ventilation, thermal mass, shading
strategy and green walls, and are illustrated in three case studies: Masdar City,
Madinat Jumeirah, and Liwa International School in the cities of Abu Dhabi,
Dubai and Al Ain respectively. The design and performance of these projects are
analyzed and evaluated, with emphasis on passive and sustainable strategies.
