Abstract

In order to quantify energy saving effect of existing building envelope reconstruction, the paper makes the envelope reconstruction project of Jinan Lixia Office Building as a case, uses energy consumption simulation software DeST-C to make dynamic simulation analysis on several aspects such as natural room temperature, cold and hot load before and after reconstruction of experimental building in cold area. After reconstruction, accumulative hot load of building obtained by calculation decreases 33%, accumulative cold load decreases 15.67%, total load decreases 21.04% in the whole year, and the results show energy saving reconstruction effect of existing building envelope is remarkable.
