This project belongs to the field of civil construction engineering and energy and environment technology. The university park is a large-scale park integrating teaching, scientific research and life. In 2017, the building volume of Shanghai universities was 36.48 million m2, with an average annual growth rate of 4.5%. The number of students in the school was 590,000, showing the variety of energy sources and the mobility of people., and the characteristics of many building function types, there is huge pressure on campus energy conservation management. There are mainly the following common problems: 1) The degree of refinement in energy management in colleges and universities is not enough. The current annual static evaluation indicators cannot achieve dynamic evaluation of prior prediction and in-process judgment of energy use in colleges and universities. It is necessary to establish a multi-dimensional comprehensive evaluation indicator system coupled in time and space. 2) Single energy management method. The existing management method only relies on the measurement systems of four major sub-items, which are too granular to meet the personalized needs of energy-saving and emission reduction management in university parks for sub-items, household and classified measurement, and realize the technical benchmarking of different energy-using spaces and energy-using systems. In order to effectively improve the comprehensive energy efficiency of the campus, the research team has achieved technological breakthroughs in multi-source and heterogeneous data collection after nearly 6 years of technical research and project practice, and established dynamic energy consumption evaluation methods and indicators for the unique energy use characteristics of colleges and universities. It has also carried out key technological research on energy-saving control of air-conditioning networked intelligent centralized control, distributed solar energy and air source heat pump hot water systems, and achieved the following technological innovations: 1. Innovatively realize multi-source and heterogeneous data collection in university parks, breaking through the isolated information collection information islands of heterogeneous data of multiple energy types and multiple building types, and forming a five-in-one energy consumption monitoring system for multiple campuses, multiple departments, and multiple buildings&&. The "Guidelines for the Construction and Management of Campus Energy Conservation Supervision Systems in Shanghai Colleges and Universities" and the "Technical Specifications for the Application of Energy Conservation Supervision Systems in Colleges and Universities" were formed and applied in engineering, with a total area of more than 2.957 million square meters. The research results were adopted by the Municipal Education Commission and used for the construction of campus energy consumption monitoring systems in colleges and universities in the city. 2. Take the lead in establishing a complete set of technologies for energy consumption monitoring, dynamic energy use evaluation and energy-saving diagnosis for refined management of college campuses. Original embedding artificial intelligence algorithms into the energy consumption monitoring system for dynamic prediction and diagnosis beforehand and during the event. The established energy consumption evaluation indicators for colleges and universities can realize the control of energy consumption quotas for different types of colleges and universities, different departments, and different types of buildings. The system is directly applied to 6 campuses and large parks including Shanghai Ocean University. 3. Innovatively propose energy-saving regulation technologies for energy use systems in colleges and universities. The established air-conditioning networked intelligent management platform has realized real-time monitoring and intelligent centralized control of temperature, humidity, and air-conditioning power consumption items of different functional buildings. Based on the dual goals of energy conservation and economic operation, distributed solar collectors and air source heat pumps have been established in student apartments. Intelligent control optimization technology for gas boiler heating water systems has achieved the maximum utilization of solar energy resources. Combined with the development of external window sunshade control technology, wind and light complementary street lights, elevator potential energy recovery, solar photovoltaic roofs and charging stations, a suitable energy-saving technology system for colleges and universities has been formed. Shanghai Ocean University alone has achieved annual energy conservation and consumption reduction. 746 tons of standard coal. The research results have formed 2 industry and local standards, obtained 4 patents (including 3 invention patents), 8 software copyrights, published 15 papers, 8 direct engineering applications, a building area of 3.242 million m2, and direct economic benefits of 529 million yuan. The core demonstration project was jointly awarded as a conservation-saving public institution demonstration unit by the State Administration Bureau of Organs, the National Development and Reform Commission, and the Ministry of Finance in 2015. After technology novelty search and level appraisal, the comprehensive technology development of energy-saving on colleges and universities is novel, and the comprehensive technology development of this project has reached the international advanced level.
