寒冷地区乡村住宅外围护结构能耗计算及节能设计

Energy Consumption Calculation and Energy-saving Design of Village House Enclosure Structure in Cold Area

建筑围护结构节能是建筑节能的重要组成部分。我国寒冷地区既有乡村住宅多属砖混结构,围护结构过于单薄、保温水平低,建筑运行陷入了高消耗、高排放、低舒适的恶性循环。文章通过对乡村住宅的典型户型外围护结构能耗指标的理论计算,提出适宜该地区乡村住宅节能30%和50%的外围护结构节能设计方案。

The energy-saving of building enclosure structure is an important part of building energy-saving. In the cold area of China, the village houses are most of concrete and brick structures. The enclosure structure is too thin and weak and the level of heat insulation is low. The building operation traps into a vicious cycle of high energy consumption, high emission and low comfort. The article, through theoretical calculation on energy consumption indexes of the enclosure structure of typical village house, puts forwards the enclosure structure energy-saving design scheme which saves energy by 30% and 50%.
