某商业建筑中庭被动式节能优化设计

Optimal Design for Passive Energy-saving Strategies of Atrium in Commercial Buildings

本文综合利用多种模拟软件,分析了4个不同气候分区的商业建筑中庭分别在有无内遮阳、不同热工性能外围护结构和不同通风方案下的室内热舒适度、能耗和室内采光效果的差异,提出了一些改善室内光、热环境和节能的措施。结果表明,通过一些节能措施可以改善建筑商业中庭的光、热环境,降低能耗。但不同气候条件下相同节能措施的节能效果有较大差异,建议建筑设计师应科学地、系统地分析问题,充分利用自然条件和绿色技术创造良好的室内环境并降低能耗。

In this paper,using the multiple simulation softwares,the indoor thermal and light environments and building energy consumptions of the atriums in commercial buildings in different climatic zones were analyzed under different shade,building envelope thermal performance and ventilation conditions. Furthermore, some measures to improve the indoor thermal and light environment and energy conservation were proposed. The results indicated that the acceptable indoor thermal and light environment could be achieved and the energy consumption could be lowered simultaneously with the optimal design strategies. Besides, for different climatic zones with same energy-saving strategies, there existed difference for energy conservation effects. It was suggested that architects need to systematically and scientifically analyze the design schemes and make full use of the optimal design strategies to realize suitable indoor environment with energy efficiency in atrium.
