Passive Energy Saving Technology For Primary And Secondary School Building Life Cycle Energy And Carbon Studies

Today,climate change and energy shortages are major challenges,and must be taken to keep global temperature rise below 1.5° C pre-industrial level.Implementation of effective building energy conservation and emission reduction strategy is an effective measure to deal with this challenge,and passive energy conservation technology is one of the important ways to achieve building energy conservation and emission reduction.With the rapid development of primary and secondary school buildings,the building area and energy consumption is increasing.According to the use characteristics of primary and secondary school buildings,it is particularly important to realize the passive energy-saving design of primary and secondary school teaching buildings.Aiming at the inclusion energy and carbon emission increase caused by the cost of passive energy saving technology,this paper uses building life cycle research to determine the energy conservation and emission reduction effect of passive energy saving technology.The main research contents and results are as follows:(1)According the research status of building life cycle,the system boundary of building life cycle is defined and the theoretical calculation model is established.And the life cycle energy consumption and carbon emission impact assessment indexes of passive energy saving technology are put forward to evaluate the use effect of passive energy saving technology.(2)According to the plane characteristics and functional space of primary and secondary school teaching buildings,three basic prototypes of primary and secondary school teaching buildings,namely external gallery,internal gallery and enclosed gallery,are established as the carrier of passive energy-saving technology analysis.Four technologies,namely passive solar heating,building heat storage,heat buffer zone and building shading,were selected to conduct building simulation research in 11 secondary climate zones and solar energy enrichment areas.(3)Through the research on the energy consumption and carbon emission during the life cycle of passive energy saving technology,the results show that the energy consumption and carbon emission of the cost of will have a significant impact on the life-cycle energy saving and emission reduction effect of the technology.Low energy consumption and carbon materials are more conducive to the energy conservation and emission reduction of passive technologies.(4)To quantify the life-cycle energy saving and emission reduction effects of passive energy saving technologies,and establishes a life-cycle energy saving and emission reduction strategy for passive energy saving technology suitable for primary and secondary school teaching buildings with the building life-cycle energy saving and carbon reduction as the index.
