“…It was shown that the vaulted roof has greater thermal stability and potentially favorable daytime temperature. Hadavand and Yaghoubi [13] had reported that the convection coefficient over vaulted roof is significantly higher on the forward side and decreases after separation on the leeward side, but its variation for flat roof is not considerable. The temperature varies along the vaulted roof during the day as a result of the auto shading of roof but for flat roof temperature distribution along the roof is nearly uniform as reported by Hadavand and Yaghoubi [13].…”

“…In the Muslim World the structural abilities of vaults and domes to host large areas for social gathering beneath them have become part of the iconic traits of Islamic architecture. In hot arid regions, the bazaars of Isfahan and Istanbul with their various vaulted structures and domed structures have shown that buildings with curved roofs maintained lower temperatures during the hot summer months and reflect more radiation than flat roofs [3]. Many architects attempted to revive curved roof architecture employing domes, vaults and arcades one of the most famous is Hasan Fathy who believed that the intensity of solar radiation is spread over a larger area and heat transmission to the interior is reduced in curved roofs.…”

In the UAE modern architecture is now considered part of early attempt of sustainable design and heritage of the living city that reflects good design practices, especially after the establishment of the Urban Planning Council and Estidama Guidelines. Madinat Zayed Gold Souk/bazaar still attracts many visitors because it represents a space of specialization, tt is also a representative of ‘modernism’ of 1970s Parallel examples such as the Central Market/Gold bazaar in Sharjah also manifest architectural attempts to create architecture within cultural and environmental contexts. Traditional wind towers known as Barjeel, vaults, domes and arcades borrowed from the broader spectrum of Islamic arts, recreated in concrete act as architectural containers of heritage and spaces of socio-cultural interaction accessible to all social groups. The aim of this research is to examine modern Arab ornament and its application on buildings in the downtowns of Abu Dhabi and Sharjah. This research examines the environmental properties of the gold bazaars in Abu Dhabi and Sharjah using Formit architectural modelling software. This study outlines the importance of forms of representation of form and identity in rapidly developing Arab cities and proposes a number of solutions/designs to improve the facades, and to enhance the comfort in the building then offers scenarios to make these buildings more sustainable.

“…Therefore, the heat resulting from the radiation was relatively higher than the radiation at lower levels. The building orientation is crucial for reducing the incident solar radiation on the building envelope surfaces [59][60][61][62]. It has been found that the solar radiation could increase by 7.7% when the broader side of the building faced east.…”

Abstract:Energy performance of buildings has attracted much attention among building physicists and engineers worldwide. The effects of building heating; ventilation; and air conditioning (HVAC) systems' design upgrade on the building energy performance are the focus of the current study. The adopted HVAC system consisted of chilled ceiling and chilled beam systems served by a centrifugal water chiller. An energy simulation study was undertaken in accordance with the national Australian built environment rating system-rules for collecting and using data. A three-dimensional simulation study was carried out utilizing the virtual environment-integrated environmental solutions software. Results from the current study have shown the importance of utilizing energy-efficient HVAC systems and HVAC strategies for achieving a high building energy star rating. Recommended strategies in order to achieve the nominated star rating; as predicted by the simulation analysis; were presented. Moreover; the effects of solar radiation inside the building atrium were significant; which cannot be overcome by simply installing a low shading coefficient glazing type at the atrium skylight. In addition to providing chilled ceiling technology; a high efficiency chiller and low energy lighting; it is recommended that the building be well tuned during the commissioning period. The current approach could be extended to accommodate higher energy ratings of commercial buildings at different locations worldwide.
