基于DeST的甘肃省既有教学楼节能保温改造模拟分析

以EPS、XPS、岩棉板3组保温系统为试验材料,利用能耗模拟软件DeST对采用基层+40mm岩棉板、基层+40mmXPS、基层+40mmEPS 3组不同外墙保温层的教学楼建筑采暖能耗进行模拟分析和优化,确定最佳外墙保温层类型为基层+40mmEPS,对于节能要求较高的建筑可以考虑基层+40mmXPS。本文为甘肃省中小学既有教学楼节能改造提供了理论参考和技术支持。

Simulation analysis of energy saving and thermal insulation transformation of existing teaching buildings in Gansu based on DeST

In this paper,the thermal insulation systems of EPS,XPS,rock wool board are taken as test materials.The heating energy consumption of different exterior wall insulation layers of teaching buildings,base course+40 mm rock wool board,base course+40 mm XPS and base course+40 mm EPS,is simulated and optimized by energy consumption simulation software DeST.The best type of external wall insulation layer is base course+40 mm EPS,and base+40 mm XPS can be considered for buildings with higher energy saving requirements.This paper provides theoretical reference and technical support for energy saving transformation of existing teaching buildings in primary and secondary schools in Gansu.
