Abstract:

The influence of common and Low-E double glazing glass fenestrations on indoor thermal and daylight environments was investigated in two test rooms in the summer in Hangzhou, China. The indoor air temperature, PMV-PPD, and illumination of the test rooms were measured. The results show that the percentage of total time for PMV values within -0.7～0.7 in the test rooms with common and Low-E double glazing glass were about 50% and 72%, and the latter was much better than the former. The illumination was also beyond 110 lx on a work plane surface, which satisfied the minimum requirement of daylight for office buildings in China.

Key words: fenestration; indoor thermal environment; indoor daylighting environment; predicted mean vote
