Light Environment Design Of Outpatient Building Based On Environment-Energy Efficiency

With the acceleration of urbanization process,the number of hospitals has increased dramatically.As a special kind of public buildings,hospitals require higher indoor environmental comfort,and their corresponding energy consumption is much higher than other types of public buildings.As an important part of the hospital,the light environment design of the outpatient building is very important.At present,there are few studies on the light environment of outpatient buildings in China.Therefore,on the premise of saving energy consumption,it is worth exploring and researching to create a good light environment for hospital outpatient buildings.This paper takes an outpatient building of a hospital in Beijing as a case,investigates and analyses its light environment and lighting energy consumption from the perspective of environmental energy efficiency.Aiming at its problems,this paper puts forward an optimum design scheme from the perspective of architectural design,which makes the renovated outpatient building obtain better light environment effect on the premise of saving energy consumption,and provides a reference for improving the environmental energy efficiency of outpatient building.This paper is divided into three parts.The first part is theoretical research,through which the scientific knowledge of things is formed,which lays the foundation for the follow-up study of the paper.The second part mainly evaluates the light environment and lighting energy consumption of an outpatient building of a hospital in Beijing by means of questionnaire,computer simulation and literature research,and finds out the light environment problems existing in the outpatient building of a hospital in Beijing and their impact.The third part optimizes the light environment of an outpatient building in Beijing,compares the optimized results with the original data,and concludes that the optimization strategy is effective.
