This paper attempts to answer the question whether there is any difference in indoor environmental perceptions between people with and without respiratory allergy. First, an online survey was conducted in China inquiring respondents’ sensitivity to changes in environmental factors including indoor air temperature, indoor relative humidity, indoor air freshness, and outdoor air pollution. Totally, 1293 persons from 30 provinces of China participated in the survey, including 478 allergics and 815 non-allergics. From this investigation over 70% of allergics reported themselves to be more sensitive to four respective environmental factors than others, which was statistically higher than the ratio of non-allergics. Secondly, published studies on environmental perceptions of allergics were reviewed. Ten studies were identified and their findings suggest that perception difference of thermal environment between allergics and non-allergics may occur when subjects are not thermally neutral while perception difference of air quality remains unclear. Therefore further research on this question is needed.
