Abstract：
In the northern cold regions, most of the existing buildings were constructed in an earlier time, the building heating technology is relatively backward, existing some problems such as poor thermal comfort of buildings, high building energy consumption and so on. The envelope renovation technology is an effective method to improve the insulation performance and energy-saving performance of the extent buildings. In this paper, the envelope renovation of extant building in Tianjin is taken as an example to introduce the envelope renovation technology of walls, roof, doors and windows, which is of great significance to improve the thermal comfort and reduce energy consumption of buildings.
