住宅室内热环境与光环境互动关系的探讨

Human's Psychological Response Under Heat Environment and Light Environment

通常 ,电光源在室内照明时会产生热量 ,并对人体的热舒适产生一定的影响 ;同时 ,室内光源色温的变化会引起人们在心理上对热环境感受的差异。有些住宅由于灯光组合设计单一 ,住户在夏季最炎热时 ,往往减少室内照明电光源的开启数量达到舒适要求 ,从而降低了室内的照度 ,影响了光环境的质量 ;由于灯光设计缺乏足够的应变功能 ,到了家庭团聚、会客或冬季较冷的时候又会感到灯光有些昏暗。因而 ,建立和谐的光和热建筑物理环境 ,不仅应达到生理上的舒适 。
