The application of building energy-saving measures in city construction — Take Shijiazhuang as an example

Building energy-saving has become a significant strategic action for sustainable development. Through the"Shijiazhuang forward in every three years",this article states energy saving measures from exterior walls, roofs, doors and windows in retaining structure of the old building and the new building, and exploitation and utilization of renewable energy ,such as the solar energy and the shallow ground can .The results of the study show that the thermal insulation performance of the building envelope was improved after the reconstruction,and the corresponding measures for the energy saving effectively reduce the new building energy consumption and save the energy.
