摘　　要：合理利用天然光,不仅可以改善室内的光环境,同时也有利于照明节能。为了实现良好的光环境,设计师需要在设计阶段准确把握光环境的效果、照明系统的性能和运行情况,从而进行合理的设计。随着计算机技术的发展,光环境模拟软件因其成本低、周期短和准确性高日益受到人们的重视,并在包括设计、建造、维护和管理等各阶段的建筑全寿命周期内得到了广泛应用。本文对目前常用的天然光光环境模拟软件进行了分类和简要介绍,并选择WINDOW、Sunshine、Radiance、Ecotect、Daysim等软件进行了比较分析,以便于使用者针对不同的应用进行选择和应用。With the reasonable use of nature light,not only the indoor light environment can be improved,but also the energy-saving for lighting system can be realized.In order to obtain the comfortable light environment,the light environment effect and the performance and operation conditions of lighting system should be exactly grasped by the designers during the design period,therefore,the rational design could be finished.With the development of computer technology,the simulation softwares for light environment have become popular due to the low cost,short calculation period and high precision.They were widely used in building whole life cycle,including the periods of design,construction,maintenance and management,etc.In this paper,the common simulation softwares for natural light environment were classified and introduced,also the softwares of WINDOW,Sunshine,Radiance,Ecotect and Daysim were compared,which was helpful for users＇ selection and application.
