Using heat pipes as heat transfer elements, and porous ceramic tubes as water saturated media material integrated into regenerative indirect evaporative cooler (R-IEC) can sufficiently decrease air temperature with considerable minimum water consumption rates for evaporative cooling applications in buildings. As the performance of evaporative coole...
Article
Full-text available
The recent construction boom has led to new urban development dynamics in Gulf cities driven by real-estate speculations and large infrastructure investments. While in the past affordable housing for medium income migrants and their families was integrated within the fringes of old downtown areas and compound developments in the suburbs, recent inv...
Article
Full-text available
Abu Dhabi and Doha have evolved rapidly in the twentieth century due to the investment of oil and gas revenues. The fast economic growth resulted in an extensive period of urbanization. The various urban dynamics had a great impact with regards to new housing typologies during the last few decades. Doha's housing market is studied in comparison wit...

This paper traces the evolution of housing typologies in four major cities in the Gulf region, namely Doha, Dubai, Abu Dhabi and Manama. The study reviews the formation and historical events in the region, which had a significant impact on new social as well as economic realities and consequently evolving housing types during the last two centuries...
Article
Full-text available
Since the end of the 1990s, large-scale mega projects have been initiated in Gulf cities to enable an unprecedented urban growth and the expansion of new economic sectors. In this respect, mega projects have played a key role in redefining housing developments in Gulf cities. This paper explores the newly emerging housing typologies and their disti...

Air-conditioning plays an essential role in ensuring occupants thermal comfort. However, building’s electricity bills have become unaffordable. Yet the commercially dominant cooling systems are intensively power-consuming ones, i.e. vapor compression systems. This paper aims to review the recent developments concerning evaporative cooling technolog...

(LEED) as a reference, to measure the green performance of Qatari buildings including the variables: sustainable site, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, and innovation and design. These variables were analysed in accordance to the current needs of Qatar and its future plan. Using the LEED variables comparatively, this project suggests adaptations to the weight assigned to these variables in the LEED scheme, to meet specific Qatari conditions for tall buildings in Qatar.
