城镇住宅建筑能耗指标分级标准体系的基础研究
[Abstract]:At present, the newly-built residential buildings in our country are designed and constructed according to the national building energy-saving design standard, which conforms to the national building energy-saving standard. However, due to the improvement of the quality of life and the increase of the per capita housing area, the difference between the per capita building energy consumption and the per household building energy consumption is enlarged. Build buildings with low energy consumption. Because of the difference in the quality of residential buildings, there is a huge difference in energy consumption per capita between different quality buildings. 20% of high-income people consume about 40% of energy. Therefore, to control the growth of building energy consumption, different energy-saving standards should be adopted for different quality residential buildings, so as to achieve high energy consumption. Building energy conservation is more responsible.
Citizens in China have equal rights to use energy, and energy consumption of residential buildings is closely related to human activities. Therefore, to study the fairness of building energy consumption, the index of per capita energy consumption can not be ignored. The energy consumption index of residential buildings is classified to achieve equity in energy use.
Taking the existing residential buildings in Xi'an as an example, the author chooses the residential buildings of different ages, areas and structures as samples, arranges and compiles the existing data and drawings, investigates the thermal parameters of residential buildings, household income and the number of household population and so on. Based on the field test, calculation and simulation analysis of performance and energy consumption index, the distribution law of heat consumption index per unit area of residential buildings with different quality grades is established. According to the theory of equity and hierarchy of demand and the method and principle of ladder electricity price, the energy consumption index of urban residential buildings is graded preliminarily.
1. With the improvement of building technology, the index of heat consumption per unit area of buildings decreases. The index of heat consumption per unit area is closely related to the structure of residential buildings and building technology.
2. Taking Xi'an as an example, the energy consumption per capita per unit area is 3 Kw 65507
3. Take Xi'an as an example, 80% of the population is middle, low-income people, 20% of the population is high-income people, according to the calculation and conversion, the per capita heat consumption index per unit area increases with the increase of residential area. The per capita heat consumption per unit area is directly proportional to the household income.
4. According to the research results, according to the per capita heat consumption index per unit area, the heat consumption index of urban residential buildings is classified as follows:
The first level: per capita energy consumption per unit area is greater than 1 Kw H / m~2 per person year less than 3 Kw H / m~2 per person, which is the first level. This is the benchmark building energy consumption index. In this energy consumption index range, no energy consumption use fee is added.
The second level: the per capita energy consumption per unit area is more than 3-3.5Kw.h/m 2.per person per year, and the second level. In this energy consumption index range, 10% of the energy consumption is charged.
The third level: the per capita energy consumption per unit area of 3.5-4 Kw H / m~2 person year or more is the third level. In this energy consumption index range, 10% of the energy consumption is charged.
Subsidy level: If the per capita energy consumption per unit area is less than 1 Kw h m~2 per person year, it is a subsidy level. Under this energy consumption index, not only no energy consumption fee is added, but also energy consumption subsidies should be carried out.
5. Based on the results of grading research, legislative suggestions are put forward to improve the technical standard system and legal system of building energy conservation in China.
Through the grading research on energy consumption index of urban residential buildings, this paper can provide guidance for the formulation of relevant architectural design norms, and put forward higher energy-saving index requirements for large-scale buildings whose per capita heat consumption index exceeds the social average in order to realize the real fairness of energy use. It can effectively reduce the building energy consumption of high-energy-consuming people, control the energy consumption growth of new buildings in the future, and achieve the goal of building energy conservation.
In addition, the research results of this paper can also provide some legislative technical support for the legislature. To promote the legislature to formulate mandatory normative documents is also of great significance to promote the improvement of building energy-saving legal system.
