【摘要】：被动式超低能耗住宅因其所独具的超低能耗、高舒适环境、低碳排放的特性,深受国内外一致好评,是未来建筑节能研究领域和建筑市场发展的方向以及必然趋势。我国被动式超低能耗建筑技术尚不成熟,国内现有被动式示范性建筑项目基本照搬欧洲经验与数据,参照德国被动式超低能耗建筑体系指标,直接引用国外相关技术,而目前欧洲被动式超低能耗建筑的技术集成体系还未在我国夏热冬冷地区大规模实践和成熟的解决方案。此外,我国对于被动式超低能耗建筑的判定仅限于单个构件或技术设备的独立能耗为基础,缺少对整个建筑的一次能源消耗量的定义和限值,并且对于增量成本和增量效益目前都只能进行粗略估测,因此无法客观评价被动式建筑节能技术体系的能效水平以及其增量成本和所带来的增量成本经济效益。鉴于夏热冬冷地区气象条件、设计理念等诸多方面较国内其他气候区存在较大差异,充分考虑夏热冬冷气候区住宅建筑保温、隔热和能耗控制的复杂需求,首先综合运用理论探讨、模拟研究等方式,对影响夏热冬冷气候被动式超低能耗住宅建筑能源节约水平的各分项因素进行评价,对适宜性技术策略的优劣进行定量化分析。其次,通过BP神经网络、正交试验方法将各项技术进行组合,分别模拟采用各项技术集成方案后的被动式超低能耗住宅建筑整体节能水平,建立了一套适合夏热冬冷地区被动式超低能耗住宅建筑能耗预测模型,可比较不同被动式超低能耗控制技术集成方案的优劣,指导被动式超低能耗住宅建筑的设计。此外,优选出了该地区最适宜被动式节能技术集成优化方案,该方案可作为我国夏热冬冷地区被动式超低能耗住宅建筑的技术集成体系。最后,对夏热冬冷地区被动式超低能耗住宅建筑进行了增量成本和增量效益分析,结果表明被动式超低能耗住宅建筑在夏热冬冷地区具有良好的经济效益和优越的市场潜力。
[Abstract]:Passive ultra-low energy consumption residence is the development direction and inevitable trend of building energy saving research field and construction market in the future because of its unique characteristics of ultra low energy consumption, high comfortable environment and low carbon emission, which is well received at home and abroad. The passive ultra-low energy consumption building technology in China is not yet mature. The existing passive demonstration construction projects in China basically copy the European experience and data, refer to the German passive ultra-low energy consumption building system index, directly quote the relevant foreign technologies, but at present, the European passive ultra-low energy consumption building technology integration system has not yet been large-scale practice and mature solutions in hot summer and cold winter areas of our country. In addition, the judgment of passive ultra-low energy consumption building in China is limited to the independent energy consumption of a single component or technical equipment, and lacks the definition and limit value of the primary energy consumption of the whole building, and the incremental cost and incremental benefit can only be roughly estimated at present, so it is impossible to objectively evaluate the energy efficiency level of passive building energy saving technology system, its incremental cost and economic benefits. In view of the great differences in meteorological conditions and design concepts between hot summer and cold winter areas and other climatic areas in China, fully considering the complex needs of heat preservation, heat insulation and energy consumption control of residential buildings in hot summer and cold winter climate areas, this paper first evaluates the sub-factors that affect the energy saving level of passive ultra-low energy consumption residential buildings in hot summer and cold winter climate by means of comprehensive theoretical discussion and simulation research. The advantages and disadvantages of suitability technology strategy are analyzed quantitatively. Secondly, through BP neural network and orthogonal test method, each technology is combined to simulate the overall energy saving level of passive ultra-low energy consumption residential building after adopting each technology integration scheme, and a set of energy consumption prediction model suitable for passive ultra-low energy consumption residential building in hot summer and cold winter area is established, and the advantages and disadvantages of different passive ultra-low energy consumption control technology integration schemes can be compared. Guide the design of passive ultra-low energy consumption residential buildings. In addition, the most suitable passive energy saving technology integration optimization scheme in this area is selected, which can be used as the technical integration system of passive ultra-low energy consumption residential buildings in hot summer and cold winter areas of our country. Finally, the incremental cost and incremental benefit analysis of passive ultra-low energy consumption residential buildings in hot summer and cold winter areas are carried out. the results show that passive ultra-low energy consumption residential buildings have good economic benefits and superior market potential in hot summer and cold winter areas.
