This project belongs to the field of building energy and environmental technology. Relying on the completed National Natural Science Foundation of China project, it applies and transforms research results into many large-scale construction projects, obtaining scientific and technological progress results and economic and social benefits. my country's growing building energy consumption has brought a series of energy and environmental problems, which have become the main contradiction in my country's construction field. At present, there are still many misunderstandings in the design and development of ultra-low energy consumption buildings. On the one hand, there is still a single dependence on high-technology in building environmental performance; on the other hand, there is a lack of systematic, universal and full-life ultra-low energy consumption building design technology application methods. This project proposes systematic design methods and technologies for high-performance and low-energy buildings. Through the comprehensive combination of energy system diagrams, climate parameter evaluation, performance simulation evaluation, energy consumption model analysis, experimental parameter measurement, multi-objective algorithm optimization and post-evaluation feedback, we explore the prototype and application of thermodynamic theory of high-performance and low-energy buildings, and sort out and build important mechanisms that can be applied to high-performance and low-energy building design from cross-disciplinary basic theories; Propose a method for determining and optimizing energy supply and demand strategies based on climate zoning in the early stage of design, and conduct research on paths, strategies and models of building and energy integration based on typical climate zone cases in my country; innovatively establish environmental performance evaluation indicators and feedback mechanisms that are suitable for different stages of the entire life cycle of my country's construction projects, laying the foundation for energy integration starting from the early stage of architectural design and system development based on building environmental performance; Build a material and culture-oriented material thermodynamic performance and ultra-low energy consumption building construction system, explore the impact of climate factors in different regions and internal factors of different functional buildings on the construction technology of all levels of the building; finally, break through theoretical integration, practical implementation, and regional adjustment and other bottlenecks, and pioneer the proposal of thermodynamic design methods and technical systems for high-performance, low-energy buildings. 1. China is the first in introducing thermodynamic theory based on energy system language into technical platforms, proposing data-driven technology-oriented low-energy building energy consumption model construction methods, innovating building performance and energy consumption evaluation standards, and innovatively establishing full life cycle evaluation and feedback mechanism. 2. Propose an energy supply and demand strategy based on climate zoning, combine the project practice in typical climate zones in my country to optimize the path, strategy, and model of building and energy integration, conduct in-depth research on the thermodynamic properties of materials, and establish a low-energy building construction system oriented by material culture. 3. Optimize and improve the data characterization method based on climate parameter analysis, and lead the country in proposing a performance algorithm and post-evaluation feedback mechanism based on multi-objective optimization. An environmental regulation-oriented low-energy building thermodynamic design method and technical application system has been established, realizing the system design. The key technologies of the project have independent intellectual property rights, with a total of 5 patents authorized, 2 computer software copyrights, 5 monographs have been published, and more than 10 SCI/EI papers have been published. Its key technologies are systematically promoted and applied in large and medium-sized projects, and environmental assessment and simulation optimization are carried out throughout the life cycle. It has been used in more than ten large-scale public buildings designed by the applicant, including Hangzhou Civic Center (recognized by 20 well-known industry experts in the post-evaluation), Yellow River Estuary Ecological Tourism Zone Tourist Service Center, Shanghai City Chongming Sports Training Center Buildings 1, 2 and 3, the new building of Henan Province Science and Technology Museum, and the College Student Activity Center of Jiading Campus of Tongji University. After application, the area using HVAC equipment has been reduced by 15-22%, and the percentage of hot comfort hours in the transition season has increased by 22-30%. Annual HVAC equipment operation can save energy consumption by 30%. New direct economic benefits have reached 35 million yuan. And promoted and applied to other projects, with significant economic and social benefits
