Research On Suitable Technology Planning Of Green Campus Based On LCA Evaluation

Human construction activities need to occupy a lot of land,consume a lot of resources and energy,and produce a lot of waste at the same time.As a result,the construction sector has been a major source of energy consumption and greenhouse gas emissions worldwide.There are various types of buildings on campus with different energy consumption characteristics of the national education investment increased year by year,the popularity of the particularity of campus buildings,green buildings as well as national and regional standard vacancy,an urgent need to our green buildings on campus class appropriate technologies for scientific analysis,the summary,form systematic technology application guideline.Based on the above background,in this paper,the green technology of whole life cycle cost of carbon emissions and quantitatively analysis,to obtain a two-star green building design identity certificate of two high school campus in southwest Hubei province as an example,study how green campus in the technical project planning period that accurate quick select suitable for low carbon green energy-saving technology.In this paper:(1)a number of cases of green middle school campuses in hot summer and cold winter areas have been marked by evaluation were collected to obtain common green technologies in hot summer and cold winter areas;(2)green technologies that can be used forquantitative analysis are selected based on relevant national codes and standards such as?Evaluation Standard for Green Campus?(CSUS/GBC04-2013),?Assessment standard for green building?(GB 50378-2014),? Code for design of school ?(GB 50099-2011);(3)Using campus carbon accounting method,carbon emission calculation method and carbon cost accounting method quantitative analysis of green technology;(4)based on the LCA evaluation,the weight of green technologies was calculated by using the analytic hierarchy process,and then the carbon cost weight value of 20 green technologies was calculated.Finally,the ranking of 20 green technologies was obtained.The results show that the weights calculated by AHP method based on LCA evaluation are: planning and sustainable site design is 0.19,energy saving is 0.18,water saving is 0.16,material saving is 0.17,and indoor environment quality is 0.28.Based on the ranking of green technology,designers should first consider using passive technology,then material saving technology,and finally optimize the design through active technology.
