Study on healthy building risk assessment index system
The research on the risk assessment index system of healthy building is of great significance to the improvement of building environment and the protection of people's health,and can play a role in scientific as-sessment and risk management.A healthy building risk assessment index system is constructed,which covers three stages of design,construction and operation and maintenance.Through AHP method and entropy weight method,the first-level index weights of the three stages are calculated to be 0.594 4,0.195 3 and 0.210 3 re-spectively.The uncertainty and ambiguity in the evaluation process are dealt with by the cloud model.On this basis,the risk of M Healthy Building Project was quantitatively assessed,and the risk in the design stage was at"medium risk",while the risk in the construction and operation and maintenance stages was at"low risk".Da-ta analysis shows that risk factors such as air quality(combined weight 0.141 8),noise pollution(combined weight 0.062 4),and natural lighting(combined weight 0.213 1)in the design stage contribute more to the comprehensive evaluation,while the risks in the construction stage are mainly concentrated in construction quality management(combined weight 0.096 6)and equipment operation risk in the operation stage(com-bined weight 0.057 2)and maintenance stage(combined weight 0.037 5).The research provides a scientific basis for the whole life cycle risk management of healthy buildings,and helps to promote the sustainable devel-opment of healthy buildings and the optimization of living environment.
