Abstract

With ecological problems and energy crises intensifying today, greening is essential to sustainable development. Compared with other types of buildings, hospital buildings account for a relatively larger proportion of building energy consumption. In order to realize the rapid cycle optimization of a green hospital project in the design stage and improve the green grade of the building, a pre-evaluation Building Information Model (BIM) of green hospital building performance was established in this study. Firstly, the literature review and expert consultation established the building performance pre-evaluation index system for green hospitals. Then, BIM technology is taken to extract data needed for building a performance pre-evaluation system, and the Cloud Model and the Matter–Element Extension Theory are used to build models. The final green grade calculation is realized in MATLAB. Finally, the Maluan Bay Hospital is taken as an example to test the applicability and effectiveness of the proposed model. The results show that the green hospital building performance pre-evaluation model has advantages of simulation, cyclic optimization and fuzzy quantification, which can effectively guide the design and construction of a green hospital.

Highlights

According to the “people-oriented” concept of “Green Building Evaluation Standard (GB/T 50378-2019)” and from the perspective of patients’ building needs, the green hospital building performance pre-evaluation system is divided into three sectors: indoor comfort, hospital environment and resource utilization
This study introduced an approach integrated Building Information Model (BIM) and BIM-related tools for green hospital building performance pre-evaluation
In order to optimize the performance of green hospital buildings and promote sustainable development, this study constructed a BIM-based performance pre-evaluation system of the green hospital

Summary

Introduction

With the rapid development of the construction industry, ecological problems and energy crisis are becoming increasingly severe. 40% of global energy consumption [1,2] and produce more than 30% of carbon dioxide emissions [2] as well as more than 10 billion tons of construction waste per year [3]. Environmental pollution and energy consumption problems caused by a hospital building should not be underestimated. Consumption Survey (CBECS) shows that healthcares’ total floorspace accounts for 4% of commercial buildings in the United States but consumes nearly 6% of energy sources [4,5,6]. Energy consumption of the unit building area of hospitals can reach up to 2–3 times than that of other public buildings [7]. Examining how to improve hospital buildings to achieve sustainable development is crucial
