Abstract

Doors and windows are the key components that affect the energy-saving effect of nearly zero-energy buildings (nZEBs). Airtightness energy use in buildings accounts for around 50% of the building energy consumption. Therefore, the energy efficiency performance of doors and windows is the key to achieving energy-saving indexes for nZEBs. In this paper, the airtightness of the external window of the nearly zero-energy demonstration building of Shenyang Jianzhu University is carried out. Through the testing and analysis, the air permeability performance of the external window of the demonstration building reaches 8 levels. Simultaneous testing combined with infrared thermal imaging method, qualitative analysis of the weak part of the external window airtightness is the gap between the window frame and the wall. The test results of this study can provide data support for the study of the airtightness of the external windows of nZEB in severe cold area.
