| dc.description.abstract | Passive design on building envelope is one of the most effective methods of minimising the impact of harsh outdoor condition, reducing the heat gain as well as to improving the indoor thermal condition in hot and dry climate in Yemen. Local architects of today give less attention to building envelope design to reduce indoor air temperature. This research discusses the results of the experimental and simulation studies with the purpose to reduce the indoor air temperature by applying modifications on the building envelope design. It aims to reduce the indoor air temperature of residential houses built from mud bricks in hot and dry climate of Wadi Hadhramout, Yemen, and finds recommendations for efficient method in building envelope design. The investigation was performed in two phases: first phase is indoor and outdoor fieldwork measurements in four case studies in old and new urban area at Tarim city, Yemen. Several modifications on building envelope such as fix shading projection and painting roof whitewash colour were performed. Second phase is: computer simulation using IES (VE) software was carried out to investigate the effects of other different envelope modifications. The modifications were carried out on the roof, wall, orientation, window to wall ratio and external shading devices. The investigation was carried out on each parameter and then in the last stage the combination of all ideal modifications was made. The results showed that by applying a combination of all ideal modifications, the indoor air temperature was able to be reduce compared to the fieldwork measurements. Design No.4 (D4) is the xxxii best building envelope design which recorded the highest average difference (0.76ÂșC) of indoor air temperature. In terms of the number of annual thermal comfort hours, design No.3 and 6 (D3 and D6) are the best envelope designs in which they improved the annual number of thermal comfort hours to 7.87%. | en_US |
