A Computing Model for Lifecycle Health Performance Evaluations of Sustainable Healthy Buildings

As hazardous substances generated indoors are becoming a greater social issue, sustainable healthy buildings are being increasingly spotlighted. Sustainable healthy buildings refer to those buildings that maintain a certain level of health performance for their lifecycle. The health performance can be evaluated in terms of time, space and health factors. Previous studies on healthy buildings have mostly focused on pollutant emissions from materials and evaluation indicators, and the studies conducted on performance evaluations have been limited to specific areas such as indoor air quality (IAQ). However, it is necessary to assess the lifecycle health performance of health factors including IAQ, temperature, humidity, noise and lighting. In addition, a computing model is required to easily and promptly calculate the health factors and share health performance evaluation results during the planning, design, construction and operation and maintenance (O & M) phases. The purpose of this study is to propose a computing model for lifecycle health performance evaluation (LHPE model) of sustainable healthy buildings. The LHPE model consists of a lifecycle health performance tree (LHT) model, a process model and an information model. The LHPE model is intended to be used as a tool to draw out the comprehensive health performance of buildings with ease and quickness, when the evaluation indicators of the factors are completed in the near future.
