The energy-saving design standard of public buildings in Jiangsu Province is to implement the national laws, regulations and policies on energy conservation and environmental protection, improve the indoor thermal environment of public buildings, improve the energy utilization efficiency of heating, ventilation, air conditioning and lighting systems, and reduce building energy consumption. According to the Standard for Energy-saving Design of Public Buildings (GB 50 189—2005), it is suitable for the energy-saving design of newly built, rebuilt and expanded public buildings in Jiangsu Province. Among them, what is the regulation of electric energy measurement in the energy-saving design standard of public buildings in Jiangsu Province? The following is the introduction of "Regulations on Electric Energy Measurement of Public Buildings in Jiangsu Province" brought by Construction Network for your reference.

Electric energy metering shall meet the following requirements:

1, the electric energy metering system is only used for energy-saving assessment, and has nothing to do with the measurement of the electric power department, and should not be connected in series with the electric power billing watt-hour meter;

2, for large buildings or high energy consumption buildings (installed capacity of 4000kVA and above) should be set up building (group) energy management platform. The platform should meet the data acquisition and transmission requirements of the itemized metering system, and use Chinese operating software.

3. The accuracy grade of the watt-hour meter shall be no less than1.0; The accuracy level of current transformer should be no less than 0.5;

4, watt-hour meter should be digital, and should have the function of data remote transmission. The watt-hour meter has a physical interface that conforms to industry standards, adopts standard open protocols or conforms to DL/T 645 Communication Protocol for Multifunctional Watt-hour Meter.

Substation energy metering design shall meet the following requirements:

1, and the main incoming switch adopts multi-function ammeter. The electric meter shall have the function of monitoring three-phase current, voltage, active power, maximum demand of power factor, total harmonic content and active power measurement;

2. Each low-voltage outlet switch adopts ordinary electric energy meter. The electric meter shall have the functions of monitoring active power or current and measuring active power.

The electric energy metering design of the distribution system shall meet the following requirements:

1. Lighting sockets, electric heating equipment and outdoor landscape lighting of the lighting system of non-rental office buildings shall be measured by floor or area respectively;

2 office buildings, shopping malls and other public buildings with rental units and external rental boxes should be measured according to the evaluation unit; Wards and operating rooms in medical buildings, guest rooms and kitchens in hotel buildings, classrooms in school buildings, etc. It should be measured by floor or functional area. Electrical equipment in theaters, sports buildings, libraries and other public places should be measured according to the trunk system;

3. The measurement of the front-end equipment of the air conditioning system should be able to distinguish the chiller from the auxiliary water pump system. Multi-connected air-conditioning (heat pump) system is adopted, and when the outdoor unit corresponds to the management assessment unit, the multi-connected air-conditioning (heat pump) shall be measured separately;

4. Except for the substation designed by electric energy metering specified in this standard, the air-conditioning terminal and air-conditioning socket shall be metered by floor or partition; When there are rental units in the building and central air conditioning is used, a separate meter should be set at the end of the air conditioning in the area;

5. The electricity fee shall be measured according to the equipment categories with different functions, such as elevators, pumps, fans and outdoor landscape electricity consumption.

6. Electricity consumption in special areas such as information center, laundry room, kitchen and dining room, swimming pool and gym should be measured by region.
