Study of Exterior Window’s Energy-Saving Design for the Residential Buildings in Severe Cold Region

Abstract

Measure the temperature of exterior window and surrounding walls’ inner surface, and measure interior air temperature to analyze the effect, which was brought to building energy consumption and interior thermal conditions by the exterior window of the building; studied several details of exterior window design, and proposes a method, which is separately controlling the heat-transfer coefficient according to different orientation, room’s positions and room’s functions while designing the exterior windows, in order to improve the interior thermal conditions and reduce energy consumption of the residential buildings.
