With the city 's energy-saving policy , energy saving norms enacted by the energy-saving task is imperative . In this paper, both multi-storey residential Shijiazhuang City as the research object , Shijiazhuang City , suitable for residential energy-saving technology research . Paper , based on the energy-saving integration technology as a starting point , start new energy use and building insulation , solar water heating systems and building envelope insulation system to study the status of technology development at home and abroad , such as building integrated solar roof insulation flat to pitched works , wall insulation , windows and doors , insulation, etc. , analyze its affordability , the degree of integration of the integrated energy-saving technology and building structure , technology construction maturity , climate adaptation , energy efficiency , cost recovery period , social feasibility of implementing and so on. By the success stories of both urban multi-storey residential building energy-saving , sum up experience, excellent way to find out the Shijiazhuang City can learn from , and combined with the existing multi-storey residential energy-saving status quo in Shijiazhuang City , list the specific programs and analyze the description of a fundamental solution to the existing situation of Shijiazhuang City, the multi-storey residential building energy saving , to explore a set of Shijiazhuang City residential buildings in the sound development of high-efficiency energy-saving programs . First, given the social basis of Shijiazhuang City, and affordability, solar hot water system as a mature application of new energy technology can be widely spread through the analysis of solar hot water system works and renovation design principles , technical means Shijiazhuang City, the transformation of the existing multi-storey residential comparative analysis of the solar hot water system integration technology were applied to the sloping roof , flat roof and wall . Secondly, Shijiazhuang City, both the envelope insulation transformation of the multi-storey residential , respectively , were analyzed from three aspects of roof insulation technology, external wall insulation , windows and doors insulation technology compared Wai applies to the built environment of Shijiazhuang City retaining structure insulation integration technology. Papers innovation is to investigate the existing multi-storey residential renovation systematic integration technology , practicality, economy, suitable for Shijiazhuang City, the city's promotion of universal , unified at the same time to reach the city 's existing multi-storey residential modification technology , energy efficiency play to the maximum.
