寒区体育馆建筑节能系统协同优化

Collaborative optimization of building energy conservation system of gymnasiums in cold region

天然采光和自然通风对建筑能耗都有着复杂的影响,对两个系统进行协同优化有助于提高建筑的节能水平。采用环境有限元数值模拟软件,建立寒区体育馆模型,对天然采光和自然通风系统进行协同优化节能研究。研究结果表明优化后采用外扩式的天窗均匀分散在室内进行采光,开启天窗1/2作为排风口使用,能够节省能耗20%以上。

Natural lighting and natural ventilation have a complex impact on the building energy consumption. The collaborative optimization of the two systems will help to improve energy saving level of the buildings. Using environmental finite element numerical simulation software, model of the gymnasium in cold region is established, and natural ventilation system to optimize energy conservation research. The results show that the use of external expansion of the skylight evenly dispersed in indoor lighting and open the sum＇oof halt＇ of use as a vent, which can save energy consumption greater than 20%.
