Abstract

This study collected samples from 93 residential buildings in Shanghai. Based on the change of CO2 concentrations measured in these samples, we have analysed the relationship between bedroom air infiltration ratio and the residential characteristics during night, when doors and windows were closed, from 00:00 a.m. to 6:00 a.m.. The result shows that the average CO2 concentration in the bedrooms was 1448 ppm at night. CO2 concentrations from 89.2% of the tested bedrooms were higher than the upper CO2 level required by GB/T18883-2002 (over 1000 ppm). Analysis of variance shows significant factors affecting the bedroom air infiltration ratio at night including the type of window, season, gap-length of doors and windows, and type of residence. These four factors rank according to Spearman correlation analysis as follows: window type, detection season, door and window gap length, residential type. This paper is significant for its guidance on keeping the balance between building energy consumption and indoor air quality.
