Technology Research on Energy-Saving Transform of Exterior Wall of Existing Emporium Building in Handan

In order to research energy-saving transform of public building, six the large and medium-scale emporiums in Handan were selected as object. On the basis of investigation into typical department emporium, set an elementary model of emporium building, made out the four different transform program to improve heat preservation of exterior wall, such as used double-layer window and added heat insulation layer and air-interstratified to exterior wall etc., and separately used the energy consumption of exterior walls and economic indicators for comparative study. According to the local climate characteristics, proposed an effective energy-saving measures for the exterior walls of emporium building in Handan, provided the basis and reference on the energy-saving policy of existing the large and medium-scale public building.
