Literature review and energy consumption analysis of winter air infiltration in large space buildings

 Air infiltration is a significant factor affecting the heating energy consumption of buildings in winter; however, the actual situation and mechanism of air infiltration in large space buildings have not been demonstrated in detail yet. Reviews the researches on winter air infiltration in large space buildings and summarizes its influences on heating load and indoor environment. Furthermore, theoretically analyses the heating load caused by air infiltration, and the result indicates that the heating load caused by air infiltration in large space buildings accounts for 66% to 85%, which is obviously higher than that in other normal buildings such as office building and residences. Besides, summarizes the key influence factors of air infiltration and puts forward the possible solutions, which can provide guidelines in both design and operation processes of large space buildings to decrease the influence of winter air infiltration.
