1 Introduction At present, my country is already the second largest energy producer and consumer in the world. Statistics show that my country’s building energy consumption accounts for about 28% of the country’s total energy consumption. Among the 2 billion square meters of buildings newly built in my country each year, 99% It is a high energy consumption building; and only 4% of existing buildings have adopted energy saving measures. Large-scale public buildings not only have high energy consumption density, but also have very serious energy waste. They have huge energy-saving space. The promotion of building energy-saving is imperative. Energy-saving and consumption-reduction are the first priority. Since the "Thirteenth Five-Year Plan", Shandong Province has achieved remarkable results in building energy conservation and green building. It has built 360 million square meters of energy-saving buildings, obtained 6 million square meters of green building label projects, and implemented 78 million square meters of energy-saving renovation of existing buildings. The energy-saving supervision system for office buildings and large public buildings has basically been established. However, it also faces some more prominent problems, mainly: the urban and rural construction mode is relatively extensive, the construction and use of buildings consume high energy resources and the utilization efficiency is low, the supervision mechanism of the whole life cycle of the building is not perfect, and the development level of green buildings needs to be improved. Vigorously carry out green building actions, and guide urban and rural construction with the concept of green, recycling, and low-carbon, which will help improve the efficiency of resource and energy use, alleviate the tension between resource and energy supply and demand; help reduce the total energy consumption of the society, reduce pollutant emissions, and ensure that energy saving Schedule tasks; help promote the optimization and upgrading of the construction industry, cultivate strategic emerging industries such as energy conservation, environmental protection, and new energy; help improve the comfort and health of buildings, and improve the production and living conditions of the people. All levels and departments should take the green building action as an important part of vigorously promoting the construction of ecological civilization, further enhance the sense of responsibility and urgency, make overall plans, pay close attention to implementation, and promote urban and rural construction onto a green, circular, and low-carbon scientific development track To promote comprehensive, coordinated and sustainable economic and social development. 2 Design basis "Shandong Province Construction Energy-saving Technology and Product Application Certification Management Measures" GB-T 15587-2008 "Guidelines for Energy Management of Industrial Enterprises" "Technical Guidelines for Evaluating Enterprise's Rational Use of Electricity GB" "General Rules for the Preparation of Enterprise Energy Saving Planning "Enterprise Energy Audit Technology General Rules-GB" GBT23331-2009 "Energy Management System Requirements" GB-50052-2009 "Code for Design of Power Supply and Distribution System" National and industry standards for energy consumption measurement devices DL/T 645-1997 Multi-function electric energy meter communication protocol DL/T 645-2007 Communication protocol for multifunctional electric energy meter CJ/T 188-2004 Technical conditions for data transmission of household meters GB/T 19582-2008 Industrial automation network specification based on Modbus protocol 3 Project overview The Dongying Plateau Petroleum Equipment Engineering Technology Center project is located in the core area of ​​Dongying New City, south of Fuqian Street and east of Dengzhou Road.
