Study Of Civil Buildings Energy Demand And Environment Load

In sustainable development field, difficulties in human's development should be discussed and studied from the viewpoint of "Energy-economic-environment" system. Both economic and energy demand have been growing fast for these years in China, and at the same time, living energy consumption and building energy consumption both rise up. Thus energy demand and environment load of civil buildings is relative closely to the sustainable development in China.On the basis of sustainable development theory, public good theory, public economics theory, and object management theory, this paper builds the simulation model on energy demand and environment load of Chinese civil buildings, thoroughly studies the sustainable development mode of building energy saving of China, and establishes an energy saving object management system.This paper firstly proves the applicability of system dynamics of research on civil buildings energy demand and environment load, and then take critical structure analysis of the sub-systems, establishes the prediction simulation model on civil buildings energy demand and environment load and takes the positive analysis finally. Based on the model calibration and calculation, combined with several scenarios analysis, the future building energy consumption and environment load in Shanghai are concluded.Based on the analysis of calculation results, this paper points out the growth trend of energy consumption and rational development of energy saving of Shanghai residential buildings; with the comparative analysis under various scenarios, it draws a conclusion that both punitive and incentive measures should be included in economic policies to stimulate users' initiative. And this paper evaluates the effect of China's energy saving policies in the different stages by the growth rate of civil buildings energy consumption, defines elastic factor of building environment consumption, named as evaluation indicator of civil building sustainable development, to evaluate the sustainable development state of energy saving under the different scenarios, analyzes the ecological development mode of Shanghai civil buildings in the future.This paper summarizes energy saving experiences of the developed countries. points out the existing problems and reasons of China, establishes the energy saving object management system model for China, and proposes many refinement measures of the system, including management tools of administration regulation mechanism, implementation of economic incentive policies for energy saving, obstacles in energy efficiency service system, and necessary energy efficiency technologies and standards.
