2. Lighting energy saving:

(1) Implement the lighting power density target value standard in the national architectural lighting design standard (GB50034-20 13).

(2) The tricolor T5 straight fluorescent lamp with high luminous efficiency and energy saving is mainly used as the light source in places below 4.5 meters high, with luminous efficiency greater than 90lm/W and color rendering index greater than 90Ra. Metal halide lamps are mainly used as light sources in places with a height of more than 4.5 meters. They are equipped with energy-saving inductive ballasts and built-in capacitance compensation. The power factor should not be less than 0.9, the luminous efficiency should be greater than 70lm/W, and the color rendering index should be greater than 65Ra.

(3) The lamps shall be energy-saving lamps with high efficiency, comfortable light and low maintenance cost. Meet the national requirements for lighting energy saving. Lighting efficiency requirements: open type ≥75%, transparent protective cover ≥70%, frosted protective cover ≥55%, and grille ≥ 65%; Lighting uses light sources with high light efficiency and good color rendering and energy-saving lamps with reasonable light distribution, safety and high efficiency; Ballasts should be energy-saving inductive ballasts or electronic ballasts, and the power factor should be above 0.9, and the lighting power density of each room or place should not exceed the target value.

(4) Select intelligent lighting system to control public lighting. Use the manual rocker switch to control the lighting place, so that it does not exceed two lights and one control, or in a large space, the control area of a single group does not exceed 20 square meters, and the lights at the window are controlled in groups.

3. Electric energy metering management:

The power supply mode is high supply and high meter, and the power supply department is responsible for the measurement of high voltage electricity. Low-voltage metering part: public lighting, elevators, fans, water pumps, air conditioners, etc. It is measured separately.

4. Building energy consumption monitoring system:

(1) The sub-metering method of electric energy shall be implemented according to the Design Standard for Building Energy Efficiency (GB50 189-20 15).

(2) The collection and uploading of electric energy consumption data should be completed automatically.

(3) The energy consumption data collected by the energy consumption monitoring system should be uploaded through standard communication interfaces and protocols.

(4) The classified energy consumption and itemized energy consumption data of the energy consumption monitoring system shall be automatically and regularly transmitted to the superior monitoring platform.

(5) Select digital ammeter with data remote transmission function, and realize remote meter reading function in the property management room through data bus.

(6) The cold and hot air conditioner can be remotely read in the property management room through the data collector, and the professional company will carry out further design.

(7) The remote hot and cold water meter is selected, and the remote meter reading function can be realized in the property management room through the data collector, and the design is deepened by professional companies.

5. Other energy-saving measures

(1) Adopt high-efficiency and energy-saving transformers, and reasonably select the number of transformers. The substation is close to the load center. The power distribution room adopts effective safety protection measures such as vibration and noise reduction and electromagnetic radiation shielding.

(2) The reactive power automatic detection and switching device is adopted to improve the power factor, effectively improve the power transmission performance and reduce the loss.

(3) All elevators in the building use energy-saving elevators and adopt energy-saving control mode.
