Zhangjiakou a Residential Building Envelope Structure Optimization Design

Abstract:

The energy consumption of a residential building Zhangjiakou area in different envelope was numerically simulated by using DeST software, and the influence factors on building energy consumption was analyzed, which provides a certain reference for optimization design of building structure Zhangjiakou region.
