This project is a national authorized invention patent technology, which has won the "Shanghai Science and Technology Progress Award" in 2016 and the "China Construction Society Science and Technology Progress Award" in 2015. It belongs to the achievements of green building energy-saving technology. It focuses on the construction plan of the Ministry Key Laboratory of Ecological and Energy Conservation in High-Density Human Settlements at Tongji University, National Natural Science Foundation, and the National "Twelfth Five-Year" National Science and Technology Support Plan. Through multi-departmental collaboration, it forms a comprehensive demonstration of integrated research and development in production, academia, and research. Innovation Points of the Achievement: The main achievements of the project include invention patents: a laser dynamic analysis method for precise measurement of buildings and urban spaces, "Method for Analyzing and Calculating Building Volume," "A Method for Reducing Regional Building Energy Loss," and "A Particle Image Velocimetry Method for Precise Measurement of Buildings and Urban Spaces." "Ecological power generation system utilizing urban road space" and utility model patent: air flow energy-saving window, etc. This technology uses digital photogrammetry to accurately measure buildings and urban spaces for effective energy-saving analysis of the entire building and urban space. In terms of PDA laser dynamic analysis technology, it is innovatively proposed for the first time to establish a simulated structure of buildings and urban spaces, providing innovative design planning. Advanced indicators: It is innovatively proposed for the first time to use particle image velocimetry technology, which can quickly, reliably, and accurately provide relevant data on the spatial environment of buildings themselves and the interrelationships between buildings within urban spaces. Coupled with the innovative design of air flow energy-saving windows, it can provide corresponding energy-saving solutions for the diverse needs of different users. The window uses a double-layer transparent glass material, with a structure for placing sunshade louvers in between the two layers of glass material. Improved energy-saving performance of building materials. Application scope: The project results have been successfully applied in urban planning and architectural design in cold regions such as China's northernmost areas, where winters are cold and summers are hot. The application range includes various types of projects such as central city commercial districts, natural landscape belts, urban residential areas, new industrial parks, and old city renovation. The project results have shown significant effects in the planning and construction of large-scale high-end residential areas such as Mudanjiang Xinyang Oasis Chuncheng. Expected economic and social benefits: The project, by using this technology, has directly and indirectly reduced a large amount of energy consumption, achieving good social and economic benefits. It provides scientific technical support for improving the energy-saving environmental quality of human habitation and promotes the development of energy-saving technologies in architectural urban space environment design. In addition, this achievement will comprehensively apply big data analysis, Research on the comprehensive utilization of water bodies in sponge cities and their impact on building space environment. Scientifically design the distribution of water bodies and architectural layout, effectively regulate the temperature and humidity of the building environment, slow down the urban heat island effect, and improve the thermal comfort and energy-saving effects of the building space environment. Investment amount, financing plan: The government introduces project matching funds, actively supports project construction, and at the same time, transforms national patents into joint cooperation for development and application to achieve financing. Expected cooperative methods: The basic principle is: The government provides active support, enterprises operate independently, and combine some technical licenses for use to achieve green technology transformation cooperation between both parties.
