Basic Research On Standard System Of Residential Building Energy Consumption Index Classification

At present, China’s new residential building have been built in accordance with thenational building standards of energy-saving design.With the improvement of lifequality, the increase of the per capita housing area, which resulted in the expanding ofdifference of the energy consumption per capita and the average energy consumption.To control the growth of building energy consumption, the basic way lies in design andconstruction of low energy buildings. Due to the quality level of residential building isdifferent, resulting in the difference of per capita energy consumption of buildings indifferent quality level buildings. About20%of the high income people consume about40%of the energy. Therefore, controling of the growth of building energy consumption,it should be execute different energy-saving standards in different quality level ofresidential buildings.So that, the high energy buildings have greater responsibility ofsaving building energy.Our citizens have equal rights to use energy, energy consumption of residentialbuilding is closely linked to human activities.Therefore, to study the fairness of buildingenergy consumption, energy consumption per capita of the index can not be ignored.The energy consumption problem in view of different quality level of residentialconstruction, carried out a large number of research. In order to realize the fairness ofenergy consumption,we try to classify with different quality grade residential buildingenergy consumption indicators..In Xi’an City, both residential building as an example, select a different age,different area and different structure of the residential buildings as the sample, collected and compiled the existing data and drawings,investigate and collect the thermalparameters, household income, family population and so on. According to the indicatorstest, calculation and simulation analysis of different quality grades of typical buildingthermal performance and energy consumption, established the distribution of heatconsumption index of different quality grade residential construction unit area. On thisbasis, combined with the distribution characteristic and rule, status quo analysis ofunit area residents living consumption index of residential building as well as per capitahousehold consumption index and using the equity theory, hierarchy of needs theory,method and principle of ladder price reference, made the initial grading for urbanresidential building energy consumption index. The main research results are as follows:1．With the improvement of construction technology, building’s heat consumptionindex per unit are decreased. The heat consumption index and per unit area is close tothe residential building structure, building technology.2．In Xi’an, for example,80%of the population, per capita energy consumption perunit area index is3Kw·h/m~2·man·year, population is15%people, accounts for15%ofthe population, the population proportion index of heat consumption per unit area is3-3.5Kw·h/m~2·man·year, accounts for6%of the population, the population proportionindex of heat consumption per unit area in3.5-4Kw·h/m~2·man·year people.3. In Xi’an, for example, account for80%of the population is the medium andlow-income people,20%of the population is high income people.According to themeasurement and conversion, heat consumption index per unit area is increase with theincrease of the residential area. Our investigation of the residential area, with worth alsoincrease with the increase of the income and the per capita income. Urban residentialbuilding’s index of heat consumption per capita and per unit area have inverseproportion relation between family economic income.4． According to the results, based on the index of heat consumption per unit area,the urban residential building heat consumption index to make the followingclassification:The first stage: per capita energy consumption per unit area in greater than1Kw·h/m~2·man·year, who, in less than3Kw·h/m~2·man·year.This is the index ofbenchmark for building energy consumption, energy consumption index in this interval, no energy consumption fees to be charged.Level second: per capita energy consumption per unit area in3-3.5Kw·h/m~2·man·year, who, for the second level, within the range of the energyconsumption index, additional energy consumption costs10%.Level third: the per capita energy consumption per unit area in3.5-4Kw·h/m~2·man·year, who, for the third level, within the range of the energyconsumption index, further increase energy use fees for10%.Subsidy level: per capita energy consumption per unit area less than1Kw·h/m~2·man·year, who, to subsidies under the energy consumption index, not onlyno energy consumption fees to be charged, instead it should be given energy subsidies.5. According to the classification results, put forward the suggestion on perfectingthe construction onf energy-saving technical standards system and legal system.In this paper, the classification study of urban residential building energyconsumption indicators, can provide guidance for related building design code, theindex of heat consumption per unit area than the social average energy-saving index oflarge family construction put forward higher requirements, in order to realize the fairuse of energy. Through these measures, can effectively reduce the high energyconsumption of building energy consumption crowd, control the future energyconsumption growth in new construction, realize the goal of building energy efficiency.In addition, the results of this research can also provide certain legislation technicalsupport for the legislature. Based on research results to promote the legislature hasnormative documents enforced formulation, also has an important significance toimprove legal system of building energy conservation.
