Jingfang Third Area In Hangzhou Residential Energy-saving Renovation Project

As China's sustained rapid economic growth, energy supply and demand is also growing, construction of the huge energy-saving projects have been launched across the country. According to China's 20 years of building energy-saving practice, in order to achieve the construction of energy consumption structure, building envelope to reduce heat loss is one of the important professional links.In this paper, Jingfang Third Area in Hangzhou residential energy-saving renovation project for the case in light of available literature on the basis of the preliminary study design in line with the energy-saving requirements and policies under the premise of Jingfang Third Area in residential energy-saving, thermal insulation in external walls, windows heat insulation, roof insulation design, construction, policy, economic and effective application of area to explore.First of all, the exterior wall, introduced technology into ways and means to achieve clear Jingfang Third Area residential projects to adopt energy-saving methods, and this method of construction technology and quality assurance measures.Then, outside the window insulation, introduced technology into ways and means to achieve clear Jingfang Third Area residential projects to adopt energy-saving methods, and this method of construction technology and quality assurance measures. Then, roof insulation, introduced technology into ways and means to achieve clear Jingfang Third Area in residential projects to adopt energy-saving methods, and this method of construction technology and quality assurance measures.Further elaborated on the concept of cost-effectiveness analysis and conditions; cost-effectiveness analysis of the implementation of the steps and calculation formula; Jingfang Third Area districts for residential energy-saving investment applications, to provide the basis of theoretical analysis. Jingfang Third Area of residential energy-saving renovation project examples, the use of "cost-effectiveness" model works in the actual effect of the external walls, windows, roof insulation materials, the use, management, economic analysis model of comprehensive evaluation, from a technical, economic on the demonstration project will not only meet the state's mandatory requirements of building energy saving and cost-effective.Finally, this article has not yet been resolved to make the prospect of some of the problems.
