Abstract:Standards ASHRAE and EN1525 1 recommend that thermal adaptive model can be taken as the basis for evaluating and designing the thermal environment of buildings with natural ventilation, but they do not consider the possible differences caused by the dropping physiological function of the elderly people.Comparative research on naturally ventilated house thermal adaptive model for 1 1 9 elderly people and 106 non-elderly people in Dalian (a cold area)is carried out and the results show that in natural ventilation the elderly people like the colder thermal environment than the non-elderly people for the thermal neutral temperature of the elderly people is 21.33 ℃ and the thermal neutral temperature of the non-elderly people is 22.99 ℃;the acceptable operative temperature of 80% of the elderly people ranges from 1 6.07 ℃ to 22.78 ℃,and that of 80% of the non-elderly people ranges from 18.91 ℃ to 24.59 ℃.This result could be related to the higher clothing insulation of elderly people.The preferred thermal adaptive measure of the elderly and the non-elderly people in springs and falls is to increase or decrease the clothes,and the thermal adaptive measure in summer is to ventilate the room. However,the elderly people prefer not to use air conditioners and heating equipment,and have lower satisfaction of indoor thermal environment and natural ventilation.As the disadvantaged group which needs special care, the thermal environmental design of the elderly people's residences using thermal adaptive model should take their physiological characteristics into full consideration,and increasing the adjustability of the thermal environment and strengthening the natural ventilation may greatly improve the satisfaction of thermal environment.
