Preliminary Study On The Model Of Community Energy Planning In Building Of Ecological City

Cities are the most important areas of energy use, urban planning is significant in promoting sustainable development of urban energy, establishing a rational urban energy structure and improving the quality of urban environment. But for the time being, still leading by land-use planning, the existing urban planning system that mainly relate to the energy, such as the electricity, heating and gas systems is proceed with the municipal infrastructure, without taking the initiative to combine rational use of energy and energy-saving with urban planning. In order to integrate energy planning-related into the process of urban planning, make urban planners clearly aware of the planning methods affecting energy, and the energy problem of the various aspects that should be taken into account, we introduce the part of"Community Energy Analysis"that is discussed mainly in this research. During the process of urban planning, communicating with planning departments actively is to achieve optimization of the preliminary urban design plan, and finally give out specific planning index and community energy design guidelines.According to the relationship between ecological city and energy use, the paper primarily establishes energy planning models of eco-city, and takes a specific case named Beijing Changxindian International Eco-city planning project as an example for study on how to conduct energy distribution of eco-city. The main contents are: (1) the initial establishment of community planning model of eco-city; (2) the initial establishment of calculation model of community energy planning in building; (3) proposed index system of eco-city energy planning; (4) a case study on Beijing Changxindian International eco-city planning project, trying to study on 500 hectares of land including residential construction and public buildings for energy planning with the proposed model of community energy planning and calculation, ultimately presented energy planning strategies of the total block and sub-plots.This paper plays a guiding role for the designers who engaged in the area about the model of community energy planning and calculation, the various data calculated out in the text is suitable for other cities in China, which will provide practical reference for community energy design in the future.
