Optimization and Economic Analysis of Green Public Building Envelope Structure in Chongqing

Public buildings such as colleges and universities in Chengdu can be studied from the aspects of the main factors influencing buildings’ energy consumption. This study analyzed the indoor thermal environment of the buildings and characteristics of their palisade structures, with their thermal performance and energy consumption, as main influencing factors of energy consumption. In the present study, these public buildings have been considered as the research object, their data has been measured through field investigation and theoretical analysis, numerically simulated- based on the actual features- and compared by computer simulation to describe the influence of thermal performance of different envelope structures on energy consumption. Also, the relationship between different thermal performance indexes and energy consumption is established. The advantage of this study is mainly to our green and energy-saving society. “Building a conservation-oriented and environmentally friendly society” is a basic state policy of China. Due to their high energy consumption ratio and greater difficulty in energy conservation, public buildings are the key places in emission reduction. The selection of appropriate green building technology is the key to sustainable development of public buildings.
