Research On Indoor Environmental Quality Evaluation Model And Management Information System For Large-scale Public Buildings

The indoor environments must safe-guard and enhance occupant’s health,comfortand productivity as people spend around80%of their lives indoors. At present,with theincreasing of large public buildings, constant improvement of people’s requirements onindoor environment, the comfort, health, efficiency of building internal environmenthave been higher requested. But it usually contains a lot of workers and rotators, andhas poor ventilation, which often lead to internal personnel have sick buildingsyndrome (SBS, sick building syndrome) such as headache, chest tightness and dry eye.So how to effectively promote health and efficiency of indoor environment quality inlarge-scale public building has become a new focus of concern, and accurately monitorand scientificly evaluation of indoor environment quality is the primary task ofimproving the quality of the indoor environment of large-scale public building.Aiming at these problems, this paper respectively analyzed the influence factorsof large public building indoor environment quality from the indoor thermal, optical,acoustic environment and indoor air quality four aspects, established a large-scalepublic building indoor environment quality comprehensive evaluation index systemthrough the questionnaire survey and the Principal Component Analysis; Establishedthe wireless collection and transmission network of the large-scale public buildingindoor environment quality evaluation parameters by using ZigBee technology andGPRS wireless communication technology；Established the large public buildingsindoor environment quality evaluation model with the matter-element extensionanalysis method and gray correlation analysis method, and verified the effectivenessand science of the model by example; At the same time,using the SQL Server2005database development tools to set up the large-scale public building indoor environment quality parameter database. And using Java language to develop theindoor environment quality evaluation information management system. Ultimatelyachieve the purpose of scientificly monitor and management the indoor environmentquality, and also provided data security to improve the indoor environment.This research through the exploration affect indoor environment quality of variousfactors, the qualitative and quantitative research methods, combining expect toestablish a unified indoor environment quality evaluation method, so as to create ahealthy, comfortable, efficient work environment, lay the foundation for guiding theactual architectural design and operation and environmental improvement of theeconomic analysis to make contribution.
