Thermal performance evaluation of a cool roof model in hot – dry climate

Roof is an essential component of the building envelope which exposed direct solar radiation and contributes to maximum load total cooling building; interface between indoor outdoor environments be strong enough withstand all weather conditions; it covered nearly 20–25% overall urban surface areas. In hot summer seasons, components must designed minimize discomfort. Recently, many studies were revealed showed that there can different solutions excessive heat problem through roof. But in Sudan, no significant research was conducted for cool roofs scenario, so more comprehensive experimental simulation analyses need performed climatic zones establish roof standards specific Sudan context future. The requirement thermal comfort a primary residential buildings located on hot-dry climates. performance model will analysed terms temperature compared Flat configuration Reinforced Concrete (R.C), plaster, paint –dry climate, Indore, Khartoum state, Sudan. study aims assess impact buildings, other hand indicates better profile maintains buildings. Thermal modelling undertaken term technology useful easy implement both old or under construction reduce temperature.
