为探究百叶外遮阳控制策略对室内光环境、热环境及综合能耗3个方面的综合影响,采用熵权法建立光热耦合综合能耗的评价模型,利用EnergyPlus软件模拟青岛某办公建筑夏季不同百叶外遮阳角度下的光热环境及能耗,利用评价模型对光环境、热环境及综合能耗进行综合评分,最终确定最合适的百叶外遮阳角度。研究结果表明,该百叶外遮阳控制策略不仅可改善室内人员的光、热舒适状况,还能节约室内综合能耗,可为百叶外遮阳控制策略的研究提供参考。
Abstract
In order to explore the effect of outer louver shading control strategy on indoor light environment, thermal environment and building energy consumption, a light-thermal coupling comprehensive energy consumption evaluation model is established by using entropy weight method. EnergyPlus software is used to simulate the light and heat environment and energy consumption of an office building in Qingdao under different outer louver shading angles in summer,then use the evaluation model to get a score of light environment, thermal environment and energy consumption to evaluation the optimal louver angle control strategy. In this paper, the control strategy of outer louver shading can not only improve the light and thermal comfort of indoor occupants but also save the comprehensive energy consumption, which can also provide a reference for the study of the control strategy of outer louver shading.
