According to the indoor physical environment of public green buildings, compares and analyses the performance improvement of indoor acoustic environment, light environment and thermal environment in different type buildings. Through the comparison of different green building standard systems, analyses the differences of indoor physical environment requirements among the green office building, campus building, store building, hospital building, hotel building and museum and exhibition building. According to the different requirements of the standards, analyses the technical implementation methods. For the indoor acoustic environment, analyses and calculates how to improve the performance of air-borne sound insulation of the building envelope, and obtains the influence of wall surface density on air-borne sound insulation. For the indoor light environment, studies the relationship between lighting factor and window-wall ratio by test and simulation analysis, and summarizes the steps and methods of daylighting analysis. For the indoor thermal environment, from the point of thermal comfort level, discusses the influence of the operating temperature on the thermal environment, and based on the mean radiant temperature and thermal performance of building envelope, puts forward a strategy affecting thermal comfort.
