未来乡居建筑的热工性能模拟研究

Thermal Performance Simulation of Rural Residential Buildings in the Future

针对乡村建筑室内环境热舒适性差、能耗高的问题,通过改善围护结构的材质及构造,来提高室内热舒适性,降低建筑能耗。采用ECOTECT能耗模拟软件,运用对比分析法,对未来乡居绿色设计十项全能大赛竞赛作品的室内热环境进行模拟,计算室内逐时温度、能耗、逐时得热、被动组分得热等指标,并对结果进行分析对比,以热舒适为前提、节能为目的选择适宜的乡村装配式结构体系,并为后期实际建成后的现场测试提供对比数据,为推动装配式建筑在乡村的应用提供理论依据和数据参考。

To solving the poor thermal comfort and high energy consumption in the indoor environment of rural buildings,materials and structures of surrounding structures are improved for better indoor thermal comfort and lower energy consumption. The ECOTECT energy consumption simulation software is applied, combining with comparative analysis,to simulate the indoor thermal environment and indoor hourly temperature calculation,energy consumption,including heat gain,passive group share heat gain,for the works of Future Green Country Home Design Contest of Decathlon Competition. The results are analyzed on the premise of thermal comfort and energy saving purpose,choosing the suitable rural fabricated structure system. The comparative data are supplied for the actual field testing of the finished project, providing theoretical basis and reference data to promote the application of prefabricated construction in rural area.
