This project is the achievement of building energy-saving technology. Currently, my country is entering the era of large-scale construction, and energy conservation has become an inevitable trend in building development in the future. In order to implement the concept of sustainable development and fundamentally alleviate the contradiction between my country's economic development and the supply of energy resources, we must advocate building energy conservation, ensure the rational utilization and conservation of my country's energy resources, and achieve sustainable economic development.
In order to obtain the application of the national invention patent technology, the two key technologies used in this project are the authorized invention patent, a laser dynamic analysis method for accurately measuring buildings and urban spaces, and the utility model patent air flow energy-saving window. Focusing on the high-density living environment ecology and energy conservation, projects such as the Ministry of Education Key Laboratory Construction Plan, the National Natural Fund of Nature, and the National "Twelfth Five-Year Plan" National Science and Technology Support Plan have adopted multi-department, industry, academia, and research collaborative research and all-round integration demonstration, using digital photogrammetry systems to accurately measure buildings and urban spaces to conduct effective energy-saving analysis of the entire building and urban space. Coupled with the innovatively designed air flow energy-saving window, it can provide corresponding energy-saving solutions for different users 'needs. The main innovative achievements of the project are as follows:
(1) The invention patent discloses a laser dynamic analysis method for accurately measuring buildings and urban spaces. In terms of PDA laser dynamic analysis technology, it was innovatively proposed for the first time to establish a simulated structure of buildings and urban spaces, reduce it into a fixed flow field according to scale, and then simulate urban space by blowing simulated natural wind into the flow field. Environmental conditions around space. It has successfully solved the current situation of relying on experience to implement wind environment design in urban building spaces. In terms of particle image velocimetry technology, it is innovatively proposed for the first time that building, urban space and particle image velocimetry tests can quickly, reliably and accurately provide relevant data on the spatial environment of the building itself and the relationship between buildings in urban space. This technology has solved many problems in my country's current urban planning.
(2) The utility model patent discloses an air flow energy-saving window. A double-layer transparent glass material is used, and a structure of sunshade swinging leaves is placed between the double-layer glass material. The principle of stratification is used to flow indoor air upward through the gap between the double-layer transparent first layer of glass material and the second layer of proportional material, resulting in indoor air circulation, and the louver can be adjusted according to conditions such as changes in solar radiation amount and solar radiation angle to adjust the intensity of indoor solar radiation and create a comfortable indoor environment. Improving the thermal insulation performance of doors and windows and reducing energy consumption of doors and windows is an important link in improving the quality of the indoor thermal environment and improving the level of building energy conservation. Doors and windows of residential buildings bear the two contradictory tasks of isolating and communicating the indoor and outdoor environment. They not only require them to have good thermal insulation properties, but also have functional requirements such as ventilation, sunshine, lighting, and sound insulation.
The project has been authorized for 8 invention patents, published 2 monographs, and published more than 40 important academic papers at home and abroad, including 2 SCI searches, 1 SSCI search, and 16 EI searches.
After searching for L14 novelty search by the Science and Technology Novelty Searching Workstation of the Ministry of Education, the novelty search report numbered 201636000L142209 issued on April 24, 2016 concluded that the project's research and development is novel. The comprehensive technology of this project has reached the domestic leading and international advanced level.
The project results have been successfully used in many large-scale high-end residential areas such as Mudanjiang in Heilongjiang Province, Ma 'anshan and Wuhu in Anhui Province. Among them, the direct economic benefits achieved in the Mudanjiang Oasis Spring City project exceeded 100 million yuan, saving 76.4 million yuan. 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.
