北京老城房屋围护结构性能测试与节能改造措施
Performance Testing and Energy-saving Renovation Measures of Building Enclosure Structure in Beijing Old City
摘要
Abstract
The thermal insulation performance of the ex-terior wall and the room airtightness of buildings in the old city of Beijing were tested,and the energy con-sumption model of buildings in the old city was estab-lished.Starting from improving the thermal insulation performance of the exterior wall and the airtightness of the room,and comprehensively considering the economy and energy saving,the best comprehensive renovation scheme for buildings in the old city of Bei-jing was selected.The thermal insulation performance of the exterior wall and the room airtightness of build-ings in the old city of Beijing are poor.The energy-saving effect of external wall internal insulation is better than that of external wall external insulation,so external wall internal insulation is cho-sen for comprehensive renovation.Compared with the simple renovation of thermal insulation performance and airtightness,the energy-saving effect of the com-prehensive renovation of thermal insulation perfor-mance and airtightness is more significant.Taking into account both economy and energy efficiency,the best comprehensive renovation scheme for buildings in the old city of Beijing is the external wall internal insula-tion(40 mm thick EPS board)+broken bridge alumi-num doors and windows,with a static investment pay-back period of 5.2 years.关键词
