Suitability Study Of Low-carbon Technologies In Residential Construction In New Rural Areas Of The Centrial Plains

Entering the new century, the deteriorating environment and lack of resources soundedthe alarm for humanity again and again. In2013, Prime Minister, Li Keqiang stressed that"neither beautiful scenery with poverty and backwardness, nor wealthy withenvironmental degradation is desirable" in a press conference of PC and CPPCC meeting,which suggested that we should develop the economy to improve people’s life standardswithout the destruction of our natural environment. According to the latest census, the ruralpopulation still accounted for about half of the total population in China. It is particularlyimportant to increase the income of rural residents and improve the rural residentialenvironment in order to enhance people’s life standards in rural areas.For the purpose of building a moderately prosperous society and solving the "three rural"issues, the development of new rural construction has promoted our country into a rapidconstruction period. As well known that, the construction activities not only dissipate lots ofenergy, but also have negative impact on environment. It is challenging to reduce energyconsumption and environmental pollution in the whole life cycle of building construction.Low-carbon technologies are considered to be effective on these issues, which have beenwidely used in many urban areas. Because of the low economic standard and weak awarenessof low-carbon energy, the application of low-carbon technologies develops slowly in ruralareas and is still at a preliminary stage. However, the socialist new rural construction providesa good opportunity to promote the application of low-carbon technologies in rural areas.In this paper, the Central Plains is selected as the research object, where thenatural and geographical conditions, local economic conditions and living environment areinvestigated. Based on the surveys of current situation in rural areas, the principles whichshould be followed and suitability of various low-carbon technologies in the residentialconstruction in new rural areas are analyzed. This paper focuses on the research of thefollowing four sections:(1)Based on the investigation of the village patterns, rural residential development,functional layout and spatial structure in Central Plains, the development of local residenceand housing demands of rural residents are analyzed. Meanwhile, the main problems to besolved are summarized.(2)In order to provide a reference for new rural residential construction in Central Plains,successful experience in many other areas is summarized. After that, the constructionprinciples of rural residence in the Central Plains are evaluated in terms of site selection, building space, and single building design. The significance of the new rural residentialconstruction is explored.(3)The suitability of various kinds of low-carbon technologies in the new ruralresidential construction is analyzed and discussed in many aspects, such as energy usetechnology, water reuse technology, waste disposal technology and energy-saving technologyof residential building envelope.(4)Based on the suitability study of low-carbon technology in new rural residentialconstruction, the new rural construction project example of Mei Li village is selected foranalysis. The project data which includes project program, project expectations, residentialdesign and application of various low-carbon technologies are collected. On this basis, theprofitability of this low-carbon residence is compared with traditional residence from theperspectives of materials, construction, equipment, the project’s profitability is analyze byevaluating NPV, IRR, P’t, at last, this paper is concluded that the application suitability oflow-carbon technologies that used in the construction of new rural residence in Central Plains.
