This paper investigates the potential of energy conservation in residential buildings in the city of Muscat by providing guidelines to reduce solar gain in overheated season. It aims to identify the problem of high energy consumption in modem houses and study the relationship between energy consumption and thermal performance of the building. Based on the authors＇ analysis of Oman＇s solar data, recommendations for shading devices were developed and evaluated using e-QUEST. An energy reduction of around 10% was achieved without drastically increasing the cost of construction while also taking into consideration of society＇s requirement for privacy and its concern to visually maintain cultural identity.展开更多
