Theoretical And Empirical Research On Building Energy Consumption Quota

Vital to survival and development of our society, sustainable energy consumption have close connection with worsening environment and changing climate so issues of energy are focuses in the world. From the whole life circle, building energy consumption would occupy one third of the whole society energy consumption, which makes it a crucial factor affecting China's goal of energy saving and emission reduction. With specifications to define energy efficiency, building energy efficiency management currently put too much attention to design phase so that technology-oriented policy become very popular even that some apparent accomplishment have been achieved. The goal to establish building energy consumption quota system in this dissertation is to assess building energy efficiency according to terminal consumption so that the government could take a more pragmatic approach to building energy consumption. Also, as a reverse encouragement, it would be a nice complement to incentive mechanism for building energy control so a all-around management system could be founded.At first, this dissertation established base principles for building energy consumption quota system, and then set control goal which is ensuring basic building energy need, controlling comfortable one and confining luxurious one. To reach the goal, design for the system should involve markets of energy and energy efficiency product. Necessity for government regulation on building energy supply was discussed also with the solution to the present problems in the regulation. Based on different characters of residential building, government building, public building and commercial building, regulation strategy and policy measures are prepared for each one. To promote the application of building energy products, product certification in addition to economic incentives would be executed. In this whole system, building energy consumption quota would play a significant role.Then, definition, index form, establishing method and contents of building energy consumption quota were clarified. Rationality for the quota was founded from four aspects which were paradigm, form, method and content. Quota system were constituted by statistical quota, technical quota, executive quota and actual quota. Since the former three quotas were only basis and reference for actual quota, actual quota became core in quota system. Statistical quota is simple and approximate because of its analysis on statistical data. Meanwhile, technical quota is complicated and precise due to standard scenes.Also, statistical quota and technical quota were specified from the aspects of operation.As the foundation of statistical quota, quota level table depicts probability distribution of population based on sample buildings, whose quality was determined by randomness of sampling and trueness of energy consumption data. Average of high quota levels defining basic building energy need and that of low quota level defining luxurious one, two of which belong to statistical quota, were presented by the dissertation.When establishing technical quota, buildings were obtained on random at first and then typical building was selected by cluster analysis. Basic or luxurious scene was introduced to transfer typical building into standardized one which was basis for technical quota establishment. To simplify the calculation, energy consumption was classified into divisional and sub-divisional energy consumption and time was divided into standard intervals with only key factors involving.At last, 14 office buildings in Chongqing were used as examples to verify the whole theory. The result shows that quota level form is not only critical to establish statistical quota but also basis for executive and actual quota. Standardizing of typical building is a key to technical quota. For calculation results of the example, quota levels for basic and luxurious building energy need were 0.8 and 0.2 individually from statistical quota and quota levels for those were 0.96 and 0.35 from technical quota. At last, considering that to restrain luxurious building energy need was the chief object since no quota system was executed in Chongqing before, 0.4 was selected as quota level for executive quota which was 76.1 kWh per capita.
