This project belongs to an innovative achievement in the discipline of building green energy conservation technology. Aiming at the practical problems brought by the high-density trend generally shown in large cities in China, it adopts green energy conservation technology for super high-rise buildings in high-density urban environments, passive and active control design and technology application of green energy conservation, green energy conservation design and technology application in public spaces in high-density cities, urban renewable energy application, green energy conservation renovation technology for existing buildings in high-density cities, Existing work on the optimization of the outdoor environment of the neighborhood and the ecological restoration technology of the urban environment provides strategies for the application and practice of relevant green energy-saving technologies in urban and architectural design. The high density of cities has become the main trend in the development of large cities in my country. However, the current architectural and urban green energy-saving design and technical analysis are still in directional and guiding exploration, and lack strong technical support and method guidance at the actual technical application level. In view of this, this project relies on the Key Laboratory of Ecology and Energy Conservation of the Ministry of Education for High-density Living Environment and multiple national and provincial and ministerial project funds. It is based on the high-density urban environment and pays attention to high-density performance design of urban green energy-saving buildings on the premise of satisfying comfort. A large number of research and testing experiments and academic papers focus on high-density and building green energy-saving technologies. The important scientific and technological breakthroughs of the project are as follows: 1) Key technologies for building performance optimization in high-density urban environments;2) Key technologies for green energy-saving design in high-density urban outdoor environments;3) Existing building renewal and urban environment transformation in high-density cities Key technologies; the project has been authorized for 1 utility model patent, 2 books have been published, and more than 80 important academic papers at home and abroad. The supporting achievement of this project mdash; mdash;"Research on MCDM and Performance Optimization Evaluation Methods of Environmentally Responsive Green Energy-Saving Technology for Super High-rise Buildings" mdash; is a key project funded by the Joint Research Center for Habitat Environment Ecology and Energy Conservation. The fund project is a key project fully funded by Tongji University Architectural Design and Research Institute (Group) Co., Ltd. The project results have been applied to the engineering projects of Tongji Design Institute, and through these engineering projects, they have been widely used in the practice of green buildings across the country and the world. They have also been widely used in the green building technical achievements of other cities., achieved good results. As it continues to be promoted and applied, greater economic and social benefits will be generated. The project results have promoted the development of architectural urban spatial environment design technology. It also provides scientific and technical support for my country to improve the energy-saving environment of living areas in the future, and has broad application prospects.
