摘要
基于计算机模拟技术,提出一套适用于办公建筑光环境及能耗评价的方法:首先采用光环境测评软件Daysim,从全年动态的角度对典型办公建筑的天然光光环境进行计算分析,依据办公建筑照明设计标准中对光环境指标的要求,考察不同外窗系统下天然光的利用率;并在此基础上,得到室内人工照明的需求度,选用动态环境能耗模拟软件TRNSYS,进一步得到建筑逐时的人工照明及采暖空调能耗;通过综合权衡光环境及能耗方面的性能,评选最优化方案,有效地指导建筑室内照明设计。
Based on computer simulation technology, this paper advocates an evaluation method on luminous environment and energy consumption for office building. Firstly, using the DAYSIM program to calculate and analyze dynamic natural light environment of typical office building in whole year; investigating the utilization ratio of natural light with different windows to ascertain the need of indoor artificial light by lighting design standard. Secondly, using TRNSYS program and integrated evaluation on luminous environment and energy consumption to obtain hourly energy consumption of building for artificial lighting heating and air conditioning. Finally, by comprehensive weigh of the identities of luminous environment and energy consumption to evaluate and select optimal proposal. This method will be expected to be guidelines for indoor lighting design.
