Energy efficiency investigation of 10 large public buildings in Shanghai

Based on the field investigation data, analyses and evaluates the energy consumption per unit floor area, building envelope, air conditioning system and cold and heat sources of these buildings. Through comparing energy consumption among the similar buildings, finds the causes for the difference of the energy consumption and proposes several measures for improving energy efficiency. Compares the energy consumption of the 10 buildings with the data from Shanghai Commercial Building Database and commercial buildings in USA, and presents some effective energy saving measures.
