我國建筑低碳化發(fā)展研究
[Abstract]:In the face of climate warming, the international community has taken a series of measures to develop a low-carbon economy. Therefore, our government has also formulated our country's low-carbon economy development plan in time, has carried on the massive exploration around the plan academic circles. However, there are few from the point of view of architecture. In fact, the proportion of building carbon emission to social carbon emission is more than 1/4, which is the second largest carbon source after industry. Among them, building operation is an important part of carbon emission in the whole life cycle of building, which accounts for more than 75% of the total carbon emission and has the characteristics of relatively low cost of emission reduction. Therefore, it is of great practical and theoretical significance to study the low carbonization of buildings, especially the low carbonization of buildings. In this paper, the connotation of low-carbon building is obtained by the method of literature induction, and the current research status of evaluation index, carbon emission, influencing factors and fiscal and tax policy of low-carbon building is summarized. Based on this, we calculate the energy consumption and carbon emission from 1985 to 2009 with the help of macroscopic model method and IPCC carbon emission coefficient method, and study the long-term development trend of building carbon emission by means of econometric model. Then factors affecting carbon emission are studied by factor decomposition method. In this paper, the development path of low carbonization of buildings is analyzed by geometric model method, which provides a theoretical basis for the proposal of relevant policies. The main conclusions are as follows: first, the core of low-carbon building is "one center"-low carbon emissions, "two basic points"-energy structure and energy efficiency and one home-to achieve sustainable development of human society. Moreover, low-carbon building includes two levels: broad sense and narrow sense. Second, from 1985 to 2009, the proportion of heating energy consumption in public buildings and buildings in northern cities and towns increased rapidly, while that in residential buildings decreased; in energy structure, the proportion of coal consumption decreased, and the proportion of electricity and natural gas decreased. LPG and other gas energy consumption increased. Thirdly, the carbon emission of buildings in China increased from 485 million tons in 1985 to 1.595 billion tons in 2009, with an average annual growth rate of 5.22 tons. Moreover, the carbon Kutznitz curve hypothesis does not hold true in the carbon emission of buildings, but is a U-shaped curve. Fourth, to promote the development of building low-carbon is to optimize the building energy structure, reduce the energy intensity and power carbon emission intensity. And whether the development effect is significant or not depends directly on the optimization of energy structure, and whether the inhibition effect brought by the reduction of energy intensity and carbon emission intensity of electric power can significantly offset the driving effect brought by the improvement of economic development level and the expansion of population scale. The innovation of the thesis is mainly reflected in three aspects: first, innovation in the perspective of research. It is pointed out that low-carbon buildings need to be grasped in a broad sense and in a narrow sense from the perspective of the whole life cycle and operation, and the research of the thesis is carried out from the perspective of building operation. Secondly, it points out that low carbon building is not a new thing, and there is a microcosm of traditional low carbon building in agricultural society of our country. Only in the development environment of low carbon economy, the connotation of low carbon building has been reshaped, and the carbon emission should be used to evaluate the construction so as to achieve the goal of reducing carbon in society. Thirdly, it is pointed out that it is necessary to optimize the energy structure and reduce the energy intensity and carbon emission intensity in order to promote the development of low carbonization of buildings in China. Of course, the paper ignored the building carbon sink factors, the comparative study at home and abroad is not enough, at the same time, the theoretical analysis is also slightly inadequate, becoming the main defect of the paper.
