Strategy Of Energy-saving Renovation Of Existing Buildings In Shanghai China

Resource shortages and environmental issues have become the focus of social concern. Building energy consumption has accounted for 30% of energy consumption of the whole society in China. However, at present, the vast majority of China's existing buildings are non-energy efficient buildings. Their comfort can not meet increasing demands in China. Therefore, the energy-saving renovations of existing buildings are imperative.Shanghai has the typical hot summer and cold winter climate, with Developed economies and concentrated population. This paper analyzes the obstacles of energy-saving renovation of existing buildings in Shanghai, and presents some solutions as references for the renovation of existing buildings for Shanghai and the Yangtze River Delta.National and regional energy laws and energy-saving regulations provide energy-saving technical standards and legal basis, but the applications of energy-saving technologies encountered many obstacles in the renovations of existing buildings. The main obstacles are: energy-saving institutions and organizations related to management or the executive branch does not sound coordination difficulties; the lack of independent energy-saving technologies, products and construction experience; no introduction market mechanisms; no attracting the participation of households; the lack of introduction of energy-saving technologies and Inadequate advocacy of Support policy; the lack of a Reasonable supervision System and institutions before and after renovations; over-reliance on state and local financial investors and so on.This paper analyzes the obstacles of energy-saving renovations of existing buildings in Shanghai, based on the energy-saving technology development and management experience at home and abroad. This paper stresses:a operation model of energy-saving renovations of existing building combining policy guidance, market regulation and the organizations to ensure; the introduction of market mechanisms, such as Energy Management Contract and Clean Development Mechanism into energy-saving renovations of existing building under the guidance of the government; a new assessment method combining The building energy efficiency assessment and program economic feasibility analysis; attributing energy-saving renovations of existing building to green consumption, making use of Contingent Valuation Method (CVM) for the implementation of the willingness to pay (WTP) of the households.
