A Study Of Crucial Elements In Energy Saving Based On Weibei Plain Rural Residential Buildings

The rural population is about660million and rural civil construction area is about22.1billion㎡in china, rural residential energy consumption occupies a largeproportion of the whole building energy consumption in our country, rural energyconservation technology application and promotion can affect the development of ourcountry’s economy, environment, energy, etc. Residence is rural residential buildings inpara main types of building housing is counterpoint in rural residential building is themain building type. Through the survey analysis of weibei plain rural rural residentialregions,and the present situation questionnaire survey of local residents and found theweibei plain rural housing construction level is low; Energy-saving technologyapplication rarely; Most of the rural residential envelope not have heat preservationprocessing; the air tightness of the Outside doors and Windows and thermalperformance is poorer; Plus more rural areas mainly is low-rise residential, layerdesign is too high which shape coefficient can’t meet the specification requirements, sothar residential energy consumption increases. To sum up, there are some problems inweibei plain country house, not only result in excessive energy consumption, and livingcomfort is poor. Since China’s reform and opening up, with the rapid growth of ruraleconomy, improving the living comfort has been more and more attention by ruralresidents, but with the energy problem become more prominent. promote energy-savingtechnology In weibei plain rural areas, can build a comfort thermal environment for thelocal residents,what is more slao can reduce energy consumption. The energy-savinglevel of rural residential at present stage is important research content.According to the characteristics of the weibei plain rural residential energy consumption, residential environment and indoor thermal environment testing ofdifferent architectural forms of rural residential found that the weibei plain ruralresidential indoor thermal environment is bad, there is a huge space in energy savingtechnology application. At the same time give attention to that arrives the technicalconditions of the rural areas are relatively backward, poor economic conditions,optional energy-saving materials co., LTD., the promotion of new energy conservationtechnology and materials in the countryside is restricted by various aspects of practicalfactors, therefore, proposed a final feasible energy saving technology solutions whichnot only can meet the requirements of residential energy-saving design, and alsoconsider the local technology, economy and material constraints. Based On thisanalysis of a variety of energy-saving technical measures, put forward to the keytechnology of weibei plain rural residential energy-saving, aim for achieving a betterbalance between energy-saving requirements and current situation, the requirements ofthe both, so as to ensure the maximum benefits of investment of energy savingtechnology. Then study several aspectskey technology on energy-saving walls, doorsand Windows, roof, the shape coefficient, put forward the key technique of energysaving in the application of the local solution. Finally uses the energy consumptionsoftware DeST-h which developed by tsinghua university to simulation the energyconsumption on the key techniques for the application,comparing the energy savingresidential building cooling and heat treatment of annual accumulative total load of themodel before and after the key technology application, get the energy-saving rate ofenergy saving technology, which demonstrates the key energy conservationtechnologies important impact. To hope for it can give a reference on the selection ofenergy saving technology in weibei plain rural housing to, in the area residentialenergy-saving promotion work.
