Abstract

Taking the existing office building in Xi'an as the research object, the effect of thermal mass and night ventilation on the thermal performance of the office building was investigated. The experimental work was conducted during the peak summer months of July and August. The average indoor temperature difference between with and without night ventilation was about 1 ℃. The indoor temperature difference exceeded 2 ℃ only occasionally. Thermal mass could help lowering the indoor temperature further, by as much as 3 ℃. Examining the occurrence frequency of the indoor temperature revealed that the indoor temperature was 28 ℃ or higher in most time. With thermal mass, the indoor temperature was above 28 ℃ in 21% of the time. With both thermal mass and night ventilation, only 4% of the time did the indoor temperature exceed 28 ℃. If 28 ℃ is assumed to be the upper limit for thermal comfort in an office environment, then it is possible to achieve thermal comfort for 96% of the time without the need for mechanical cooling.
