1.Background
Statistics show that 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 our country each year, 99% are high-energy buildings; and only 4% of the existing buildings use Energy-saving measures, so there is still a huge energy-saving space, the promotion of energy consumption monitoring system is imperative. Energy saving and consumption reduction, measurement first.

2. Project Information
Weifang Fashion Milan is located in Gaomi, Weifang, at the core of the Shandong Peninsula Blue Economic Zone and the Jiaodong Peninsula Industrial Focus Zone and an important node of "QingWei Integration".
The Acrel DTSD1352 electric energy meters in the building distribution box are all connected to the Acrel-5000 energy consumption monitoring system to supervise the electric energy consumption, keep abreast of the energy consumption, and improve the awareness of energy saving.

3. Structure
Acrel-5000 energy consumption analysis and management system takes workstation host machine, communication equipment and measurement and control unit as basic tools, and provides a basic platform for real-time data collection and remote management of large public buildings. It can transmit data with other building automation systems to form a complex monitoring system.
The energy consumption system mainly adopts the layered distributed computer network structure, as follows:

4.Main Function
4.1 Platform Overview
The main interface of the system can reflect the energy consumption of each branch and the comprehensive energy consumption converted into standard coal, and calculate the energy consumption per unit area.

4.2 Itemized electricity consumption data statistics
The system makes hourly, daily, month-by-month and year-by-year statistics of power consumption.The statistical data are presented by pie chart, bar chart, line chart, area chart and other graphics, which can directly reflect the value, trend and distribution of various statistical data.

4.3 Trend analysis of branch circuit
Make statistics on the power consumption of each region and equipment, accurately locate the power consumption circuit, formulate the performance appraisal system of energy conservation, and promote the effective implementation of energy conservation and consumption reduction.
In order to establish operation record files for energy-using equipment, track and record the energy efficiency analysis and evaluation results in the operation process of the equipment for a long time, and provide basis for the operation and maintenance of the equipment in combination with the equipment maintenance record.

4.4 Comparative analysis of energy consumption data
The energy consumption of various types and major energy-consuming equipment was analyzed on a year-on-year basis with the values of the same period last year and the values of the last month, and the energy-saving effect was tested. According to the analysis results, the energy-saving performance assessment was carried out and the energy-saving target was revised.

4.5 Classify the energy type, load type and regional energy consumption according to time, and compare and analyze the energy data on time, day, month, year, working day and non-working day, so as to grasp the specific energy consumption.Peak, level and valley can be set in the time period of daily energy use, and energy consumption of each period can be counted to reduce energy consumption in idle time.

4.6 Real-time monitoring and early warning of electric power data
Automatic real-time and high-density real-time energy-using monitoring can be realized by high-precision intelligent instrument with technical means to reduce the measurement error of energy-using.
Monitor the back data of the field instruments in real time, control and warn the electric energy reasonably, find and correct the abnormal electricity in the operation in time, and deal with it at any time.
The warning value of exceeding the standard of important equipment is set as required. When exceeding the standard, it should be reminded and recorded actively.

5.Project Summary
Building is a major energy saving consumer. Doing a good job in Weifang Fashion Milan’s energy saving work is of great significance to promoting and driving energy saving work and achieving energy saving and emission reduction goals.
