近年来,北京市对建筑节能工作采取了多项措施。例如,颁布了民用建筑节能设计标准及实施细则,建成了几个节能示范小区,各种保温节能材料的科研、生产有了较大的发展,也制定了一些工艺标准。但从实施情况看,有些建筑材料及工艺做法不过关,尤其是外墙内保温做法,材料、施工方法很多,问题也不少。突出表现在裂缝问题上。因而1992年北京市建委在对墙体保温材料进行评估的基础上,委托北京市住宅总公司组织实施节能示范工程。我公司承担了SC—90充气石膏保温板的课题,并在北
In recent years, Beijing has taken a number of measures for building energy conservation. For example, the energy-saving design standards and implementing regulations for civil buildings were promulgated, and several energy-saving demonstration communities were built. The research and production of various heat-insulating and energy-saving materials have made great progress, and some technological standards have also been formulated. However, from the implementation point of view, some building materials and process methods are not passable, especially in the practice of external wall insulation. There are many materials and construction methods and there are many problems. Outstanding performance in the crack problem. Therefore, in 1992, the Beijing Municipal Construction Commission, on the basis of evaluating the wall thermal insulation materials, entrusted the Beijing Municipal Housing Corporation with the implementation of energy-saving demonstration projects. Our company has undertaken the topic of SC-90 inflatable gypsum insulation board and is in the north
