夏熱冬冷地區(qū)被動式超低能耗住宅適宜性技術體系評價研究

發(fā)布時間:2019-06-15 06:36
【摘要】:被動式超低能耗住宅因其所獨具的超低能耗、高舒適環(huán)境、低碳排放的特性,深受國內(nèi)外一致好評,是未來建筑節(jié)能研究領域和建筑市場發(fā)展的方向以及必然趨勢。我國被動式超低能耗建筑技術尚不成熟,國內(nèi)現(xiàn)有被動式示范性建筑項目基本照搬歐洲經(jīng)驗與數(shù)據(jù),參照德國被動式超低能耗建筑體系指標,直接引用國外相關技術,而目前歐洲被動式超低能耗建筑的技術集成體系還未在我國夏熱冬冷地區(qū)大規(guī)模實踐和成熟的解決方案。此外,我國對于被動式超低能耗建筑的判定僅限于單個構件或技術設備的獨立能耗為基礎,缺少對整個建筑的一次能源消耗量的定義和限值,并且對于增量成本和增量效益目前都只能進行粗略估測,因此無法客觀評價被動式建筑節(jié)能技術體系的能效水平以及其增量成本和所帶來的增量成本經(jīng)濟效益。鑒于夏熱冬冷地區(qū)氣象條件、設計理念等諸多方面較國內(nèi)其他氣候區(qū)存在較大差異,充分考慮夏熱冬冷氣候區(qū)住宅建筑保溫、隔熱和能耗控制的復雜需求,首先綜合運用理論探討、模擬研究等方式,對影響夏熱冬冷氣候被動式超低能耗住宅建筑能源節(jié)約水平的各分項因素進行評價,對適宜性技術策略的優(yōu)劣進行定量化分析。其次,通過BP神經(jīng)網(wǎng)絡、正交試驗方法將各項技術進行組合,分別模擬采用各項技術集成方案后的被動式超低能耗住宅建筑整體節(jié)能水平,建立了一套適合夏熱冬冷地區(qū)被動式超低能耗住宅建筑能耗預測模型,可比較不同被動式超低能耗控制技術集成方案的優(yōu)劣,指導被動式超低能耗住宅建筑的設計。此外,優(yōu)選出了該地區(qū)最適宜被動式節(jié)能技術集成優(yōu)化方案,該方案可作為我國夏熱冬冷地區(qū)被動式超低能耗住宅建筑的技術集成體系。最后,對夏熱冬冷地區(qū)被動式超低能耗住宅建筑進行了增量成本和增量效益分析,結果表明被動式超低能耗住宅建筑在夏熱冬冷地區(qū)具有良好的經(jīng)濟效益和優(yōu)越的市場潛力。
[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.
