摘要：In January 2017,the Assessment Standard for Healthy Building(T/ASC 02-2016)was published.The issue and application of this standard indicates that healthy buildings have developed from labs to field in China.Based on it,the concept of healthy buildings has been gradually implemented in the construction industry and has achieved preliminary results.This paper conducted statistical analysis on the healthy indexes level from 48 certificated projects and quantitatively demonstrated the practical effect of health building projects in China.At the same time,through the analysis of the healthy measures for different types of projects,this study also made a statistical analysis for the operational difficulty of the provisions of the standard in practice,providing practical reference for the continuous updating and improvement of the health building standard and providing reference for the project construction and the manager’s strategy formulation.Specific conclusions are as follows:(1)The health effects of the health building projects are reflected in several aspects:The average annual concentrations of indoor PM2.5 and PM10 are 14.8 and 23.9μg/m^3,respectively;the indoor average annual concentrations of formaldehyde and TVOC are 0.043 and 0.228 mg/m^3,respectively;68.8%of the total hardness of drinking water in the project is less than 150 mg/L(calculated by CaCO3);85.4%of the main functional rooms reached the thermal comfort level of ClassⅠ;the free fitness area takes 1.9%of the total area.(2)The higher the quality of the project is,the better the balance among the healthy elements is.In general,the score of items related to water takes 59%and 55%for comfort,which are significantly lower than that of air(82%),fitness(84%)and humanity(73%).However,the degree of practice completion is relatively low.It is suggested that the standard compilers should refer to the difficulty feedback of project practice in the process of standard revision.(3)According to the difficulty index value from low to high,the provisions are
