建筑物的热性能主要取决于其热物理特性和操作特性以及当时的气候条件。清真寺在建造和操作方面是一种独特的建筑类型，如果设计和操作不当，可能成为冷却能源的主要消费者，特别是在炎热气候下。在本研究中，利用能源建模和模拟来确定由于围护结构改造措施和空调（A/C）操作策略而产生的潜在节能，同时保持可接受的热条件。结果表明，当采用适当的热改造和操作策略时，具有良好的节能潜力。当采用屋顶和墙壁保温并将空气渗透量降低到0.5 ACH时，每年可减少26%的冷却能量。通过实施适当的空调操作策略和提高系统效率，所需的冷却能源可减少约36%。由于结合了空调系统和围护结构改造措施，冷却能耗的总减少可高达48%。提出了一些关于清真寺设计、改造和空调业务战略的建议。这些预计将对世界各地的清真寺设计师和运营商有很大的用处，尤其是在炎热的气候下。
Thermal performance of buildings is mainly determined by their thermo-physical and operational characteristics as well as the prevailing climatic conditions. Mosques which represent a unique type of building in terms of construction and operation can be major consumers of cooling energy, particularly in hot climates, if not properly designed and operated. In this study, energy modeling and simulation is utilized to identify potential energy savings due to envelope retrofitting measures and air-conditioning (A/C) operational strategies while maintaining acceptable thermal conditions. Results revealed a good potential for energy reductions when proper thermal retrofitting and operational strategies are employed. As much as 26% reduction in annual cooling energy is obtained when applying roof and wall insulation and reducing air infiltration to 0.5 ACH. By implementing a proper A/C operational strategy and employing system efficiency improvements, the required cooling energy can be reduced by around 36%. The total reduction in cooling energy consumption due to combined A/C system and envelope retrofit measures can be as much as 48%. A number of recommendations pertaining to mosque design, retrofitting and A/C operational strategies are derived. These are expected to be of great use to mosque designers and operators worldwide, but particularly in hot climates.
