体育馆是一类较为特殊的建筑,对其内部的光环境质量有着非常严格的技术标准以资遵循。在目前大多数已建成的体育馆建筑中,建筑师大都舍弃了光效好、无污染的天然光,而选用了耗能巨大的人工光源。这是由于天然光本身的不稳定性、不均匀性、直射光过于强烈易造成眩光等特性;同时,这些也成为要求苛刻的体育馆建筑中采用天然采光难以逾越的障碍。 Gymnasium is a relatively special type of building, which has very strict technical standards for the internal light environment quality. Most of the currently completed stadium buildings, the architects mostly give up the good light, pollution-free natural light, and the selection of a huge energy-consuming artificial light. This is due to the instability and inhomogeneity of the natural light itself, the glare caused by the strong direct light, and the like, which at the same time has become an insurmountable obstacle to the use of natural daylighting in demanding gymnasium buildings.
