Research On Project Performance Monitoring And Effectiveness Evaluation Of Green Building In Hot-summer And Cold-winter Region

In recent years,with the rapid development of urbanization in China,the number of new buildings has increased significantly,and a large number of existing buildings have also faced transformation.The relevant resources and energy consumption has raised rapidly,resulting in increasingly prominent resources and environmental problems.It is imperative to carry out green development in the construction industry.In this paper,the research on the performance monitoring and effectiveness evaluation of the green building operation cycle is carried out.Plenty of projects that obtained green building design label were investigated to analyze the problems in the operational process.And five residential construction projects and five public construction projects were selected to conduct in-depth testing and evaluation.The economic,social and environmental benefits of green building technology were analyzed.The main research contents are as follows:Firstly,the paper adopted the qualitative and quantitative method to establish the comprehensive evaluation system with the evaluation indexes of energy consumption evaluation,water consumption,environmental quality evaluation(physical parameter test and user questionnaire survey were carried out at the same time),building service performance(user questionnaire survey)to reflect the environmental performance level of green building.Secondly,four typical green building projects were selected to carry out the monitoring and trial evaluation work.The tests of typical projects' building envelope energy saving,air-conditioning system energy saving,lighting energy saving,renewable energy use,water saving rate of water saving equipment,use rate of non-traditional water source,indoor environment of heat,wet,light,wind and sound,indoor air quality were conducted to analyze the economic,social and environmental benefits of the relevant green building technology measures.And they were compared with the relevant national energy consumption requirements to point out whether the operation energy was reasonable,which adjusts the weight of the evaluation system,and suggests the feasibility of the key technical measures in the operational process.In addition,it also surveyed the problem that the professional degree of the property management staff is not enough “green” in the operational process of green building.The management staff are not familiar with new technologies and new equipment operation,who can't take a regular statistical analysis to operating data initiatively and lack perfect property operation strategies,directly affecting the operation effect of green building.With the continuous construction and coming into use of green building,the problem of backward technology in property management continues to be serious.The property management is short of the research on management technology and methods that fit green building.On the contrary,it still follows the traditional property management technology,which can't guarantee the smooth operation of green buildings.Finally,the paper summarizes the research data in the operational process of green building,analyzes the existing problems in the green building operation cycle at this stage,and puts forward relevant suggestions.
