The Renovation Study On Energy-saving Of Existing Commercial Building In Hot Summer And Cold Winter Zone

China’s building energy career started late, compared to other developed countries abroad, building energy undertakings concerned have a big gap. Meanwhile, the existing uneven distribution of energy efficiency in buildings, hot summer and cold winter area of building energy development is relatively slow. Energy saving in public buildings, the state’s first government office buildings for energy-saving, and the development of building energy efficiency in commercial buildings is seriously lagging behind,"Twelve Five Year Plan" put forward to strengthen China only in hot summer and cold winter region residential building energy-saving requirements, energy consumption per unit area is5to15times the residential building commercial building renovation is still stuck in a simple aesthetic level, energy awareness is very weak. Existing commercial buildings for energy saving most only stay in the air conditioning, lighting transformation, the overall energy awareness is poor, and with the energy requirements continue to increase, and only from the perspective of an integrated multi-energy issues in order to better achieve energy requirements, this will start a whole, respectively, from the transformation of design techniques, related technological innovation, management policies and operations management tripartite face both the hot summer and cold winter area commercial buildings for energy saving research. Based on this, the paper consists of the following six sections:Chapter1describes the existing building energy situation at home and abroad of the environment, citing the developed and developing common energy development, re-analysis of the existing domestic public building energy efficiency, and to analyze domestic energy development gap appeared, while describes the research method, purpose, meaning, the framework presented papers.Chapter2analyzes the hot summer and cold winter zone climate characteristics both within the region and its energy consumption characteristics of commercial buildings, commercial buildings of different sizes were classified and define, analyze, hot summer and cold winter area within the commercial building renovation the status quo.Chapter3, from the architectural point of view of assessing reconstruction design commercial buildings can be retrofitted to the approach taken, comparative analysis of different types of commercial buildings can be adapted to the transformation method.Chapter4, both from the technological aspects to analyze the feasibility of commercial building energy-saving methods, respectively, building envelope, air conditioning system, lighting system comparative analysis of these three parts, Good for summer and cold winter climate characterized by commercial building energy-saving techniques.Chapter5from the social consciousness and control policy to promote the development of energy-saving, through social research, comparative analysis of the feasibility of a higher standard of judgment obtained and management mechanisms.Chapter6through the analysis of actual case to demonstrate the transformation strategy, first three Angle carries on the quantitative analysis at the same time relying on the software of calculation, calculation data were analyzed.
