寒冷地区农村建筑围护结构热工性能优化及经济性研究

Optimizing Thermal Performance and Economical Efficiency of Building Envelopes in Cold Area

农村建筑热工性能较差,采暖季能耗居高不下。本文通过Dest软件建立模型,对寒冷地区农村建筑不同围护结构下能耗情况进行模拟,并建立P1-P2经济分析模型,以全生命周期费用最小或者净现值最大确定合理的外墙保温层厚度及窗户类型。

Rural buildings have poor thermal performance and high energy consumption in heating season.This paper simu⁃lates the energy consumption of rural buildings under different enveloped structures in cold areas through Dest software.At the same time,p1-p2 economic analysis model is established and reasonable exterior wall insulation thickness and window type is determined with minimum life cycle cost or maximum net present value.
