北京农村地区居住建筑的适用节能措施分析

北京农村居住建筑大都没有采取保温措施，建筑能耗大，室内热舒适性差，有很大的节能潜力。结合北京农村建筑现状和能源使用情况，提出几种方案，采用DeST软件进行模拟分析，并结合现场测试，分析了方案的技术和经济可行性：采取岩棉、胶粉聚苯颗粒、聚苯板、袋装聚苯颗粒等措施，室内平均温度提高7—9．5℃；加装保温窗帘可以减少54％～60％的冷风渗透热负荷；每年可节约52％～61％的呆暖耗煤量，初始投入仅增加94～129元／m^2，有较强的推广价值。

Analyses of Suitable Energy-Saving Schemes for Residential Constructions in Beijing Rural Area

Most residential constructions in Beijing rural area have no effective thermal insulation, and having high energy consumption, poor indoor thermal comfort and thus great space in energy-saving transformation. To solve this problem, the systematic research on the rural residential buildings and the energy use state in Beijing rural area was conducted, and some energy-saving transformation schemes were proposed. The technical and economic feasibility of the schemes was analyzed by simulation using DeST and by on-site measurement. The results show that schemes of mineral wool, expanded polystyrene granule, polystyrene, and sacked polystyrene granule can greatly improve the thermal comfort of buildings with a rise in average indoor temperature of 7-9.5℃. The addition of thermal insulation curtain can decrease the heat load due to infiltration by 54%-60%. The coal consumption for heating will drop by about 52%-61% , and the investment will only increase by about 94-129 yuan per square meter. So the schemes are worth popularizing.
