The Study Of "Zero Energy Consumption" Building's Feasibility And Application Prospect In Chongqing Region

Based on the analysis of the natural climate, building energy efficiency, renewable energy resources distribution of Chongqing area, utilize the computer software to stimulate construction energy consumption, To exploring the feasibility of zero energy building consumption in Chongqing, as well as its application prospect. Building energy consumption is refers to the civil construction use process to the energy consumption, mainly includes the total energy which can heating, well ventilated, the air conditioning and the illumination consume, not including production and managerial energy consumption. Zero energy consumption construction is the building itself regarding non-renewable energy source consumption is zero, not the construction does not consume energy, and the most probability application renewable energy source.In this article has referred to the massive domestic and foreign zero energy consumption construction application progress, in UK, the zero energy consumption construction's research become the world leader. To 2016, all housings of Britain will be zero emissions, and the zero energy consumption had already become the limit standard in Britain. Including Germany, Russia, the US and so on, they will have the massive research to zero energy consumption construction, but in home, the research to zero energy consumption construction is just started, Zero energy consumption construction project practicing message is beginning repeatedly published in newspapers. In recent years, numerous "zero energy consumption construction" practices is starting by the single demonstrative project to become the national orienting motion.The annual rainfall of Chongqing is much more, and the annual mean temperature is higher than other areas which is hot or cold, the annual sunshine is less. The renewable energy source resources mainly have the fresh water resource, the geothermal resource, the biomass energy as well as summer's solar energy resources and so on. Because the summer temperature is high, this is get a high requirement to the construction's maintenance structure thermo technical performance, by saves the air conditioning to consume energy, in the article introduced which is suitable for Chongqing area by construction energy conservation technology in detail, including outer wall energy conservation, window energy conservation, roof energy conservation and so on. Then in view of the solar energy, the biomass energy, the geothermal energy and so on renewable resources has made comprehensive elaboration of the newly utilize technology. In order to pursue the best fit application on the renewable energy source in Chongqing area. The last dwelling construction uses optimized the energy conservation measure, using the computer simulation analysis, calculates the annual construction energy consumption, analyzes its fractional energy savings, as well as according to energy consumption choice appropriate renewable energy source substitution resources.From the full test, we can analysis that in Chongqing, zero energy consumption construction is feasible, and its application prospect is widespread. The application prospect is widespread. At present, the non-renewable resources gradually dries up, under the national initiative low-carbon life's situation, studying on the Chongqing zero energy consumption construction will have the positive significance.
