建筑地面保温与节能

采暖建筑地面的保温性能及节能水平，体现了建筑地面设计的经济性和科学性，也影响着居民的健康与舒适。我国建筑热工设计规范将地面按着反映其热工性能的吸热指数B分为三类，不同的建筑应根据其功能要求选择不同的地面。结合建筑热工设计规范的要求给出地面吸热指数量的计算方法及地面的保温措施，经实际计算可知采取保温措施的建筑地面其节能效益Q十分显著，热舒适度也相应提高。

Energy saving on ground floor of building

For a heated architecture, thermal performance and energy saving condition of its floor represent its scientific and economic benefits of its floor design. And they influence people's health and comfort as well. Heat absorption index that reflects its thermal performance is divided into 3 classes in our thermal design code for civil building. The code also requires that various buildings should adopt different types of floors as necessary. A calculating method has been developed for the heat absorption index of floor and its insulatation measure to clarify if the floor class would satisfy code requirement. It is shown with a calculating example that the floor's heat comfort and energy saving condition would be improved after adopting insulatation measure.
