高校食堂建筑光环境节能优化设计研究

Research on Luminous Environment Optimization in University Canteen Buildings in Cold Regions of China

由于我国高校食堂建筑进深较大,存在明显采光不足且均匀度较差等问题。而随着食堂在学生日常学习生活中扮演着越来越重要的角色,其功能已由单一的就餐转变为集聚会、娱乐、自习等多功能于一体。多功能复合的转变导致建筑使用模式也相应发生变化,使用时间延长使得建筑照明能耗和空调系统能耗明显增加。本文即针对高校食堂建筑采光及能耗增加的问题,基于标准模型以及标准模拟方法,分别对建筑立面窗墙面积比、天窗面积以及照明系统进行优化设计,并得到各优化设计相应的量化节能率以指导高校食堂建筑光环境节能优化设计,为学生的学习生活提供健康舒适的环境。

Because of the high depth of university canteen buildings in China,there are some obvious problems such as inadequate lighting and poor uniformity. As university canteen buildings are playing a more and more important role in students＇ daily life,its function has changed from the mere use of dining to a comprehensive system of parties,entertainment,self-study,etc. The function change has led to the variation of the using mode and the prolonged using time has caused an obvious increase of the lighting and HVAC system energy consumption.This paper focuses on the lighting and energy problem,making lighting optimization design for window-wall ratio,skylight and illumination system based on a standard model and a standard simulation method,thus finally obtaining an energy-saving rate with the method to guide the optimization of the luminous environment,which will also contribute to a more healthy and comfortable environment for students＇ study and life.
