1、摘要气候变化与能源安全已经成为人类面临的最严峻的挑战。本文实地检测寒冷地区外墙的热工性能，使用热箱法分别对CL建筑体系外墙，粉煤灰外墙和普通混凝土外墙进行检测，利用Origin软件对测的结果进行了分析。试验证明在寒冷地区CL建筑体系比其他两种外墙有更好的节能效果。同时用Ansys12.0软件对三种外墙热传导进行了数值模拟，并与实测值进行了对比分析。按照《民用建筑节能设计标准》和《民用建筑热工设计规范》计算出某住宅楼的建筑耗能。使用EQUEST建筑耗能软件研究CL建筑体系的节能预测，分析研究CL建筑体系的屋顶传

2、热系数，玻璃类型，窗墙面积比等几个因素对全年耗电量的影响，建立了这几个主要因素对全年电量的回归方程。并且分析研究CL建筑体系的玻璃类型，窗墙面积比与采暖季耗能的关系。使用回归正交实验设计选取玻璃传热系数，窗墙面积比，屋面传热系数，内墙传热系数几个因素对CL建筑体系的建筑能耗进行预测，得出多元线性回归方程，并对回归方程进行验证，为建筑节能设计提供依据。关键词：建筑节能；CL建筑体系；EQUEST；热传导；数值模拟；回归正交实验设计；能耗预测；Studyonthethermalperformancetestand
