Dahua Technology, a world-leading video-centric AIoT solution and service provider, takes energy conservation, consumption reduction and benefit maximization as its core objectives. The company adheres to its sustainable development goals involving low energy consumption, low emissions and recycling, and comprehensively plans and implements long-term strategies for energy conservation and emission reduction.

Power & Environment Supervision System

To constantly improve its energy performance and systematization, Dahua has established an energy management system and formulated the Energy Review Management Procedures. All departments shall compile their Identification Table of Energy Management Factors according to their actual situation, implement an effective system for energy consumption reduction, and regularly invite qualified third parties to identify and check their energy management efficiency.

In addition to the basic functions such as electricity and gas consumption metering, billing, and statement analysis, the system also provides online real-time monitoring of energy consumption, energy consumption diagnosis and analysis, and other related functions. It offers a comprehensive energy consumption management service to managers, improves energy management efficiency, and reduces operation and maintenance costs.

Energy Management & Control

The monitoring and measuring equipment required for energy management are calibrated and maintained in accordance with the Monitoring and Measuring Equipment Control Procedures. Relevant records are saved in order to ensure that the data provided by these equipment for monitoring key features is accurate and reproducible.

Moreover, Dahua has conducted a thorough investigation of the public electrical devices and facilities in its parks, and formulated relevant energy-saving renovation plans that include the following:

· The street lamps in Park 1187 were changed from 48W energy-saving lamps to 26W LED lamps, providing lighting for twelve hours a day and saving 3083.5 kWh (32 lamps) a year. The street lamps in Park 1199 were changed from 55W fluorescent lamps to 26W LED lamps (85 lamps), providing lighting for 12 hours a day and saving 10796.7 kWh each year.

· The lighting was changed from 54W fluorescent lamps to 122 sets of 24W LED lamps that can save approximately 21,374.4 kWh each year (16 hours of daily operation). The fluorescent lamps on two floors were changed to 500 pcs of 18W LED lamps with intelligent sensor control, which can save about 32,850 kWh each year (10 hours of daily operation).

· The park printers enter energy-saving mode if there is no operation for half an hour, taking only 0.9W of power for each printer. A built-in motion sensor detects when someone is nearby and automatically restart the device, reducing the wait time.

· The new headquarters is fully equipped with intelligent lighting, including adjustable lighting fixtures and human body sensors. In public spaces such as elevator lobbies, tea room aisles, and conference rooms, the illumination of the lighting fixtures can be adjusted accordingly: turns on when people come, and turns off when they leave. In the underground garage, when a person or vehicle passes by, the lights within the visible range (30-50 meters) will automatically turn on. It will turn off and go back to sleep mode when the person or vehicle leaves the premises, thus ensuring smart utilization of traffic lighting in the garage.

· Several 140kW photovoltaic panels were installed on the roof of the new headquarters building and integrated into the park's power grid. Using peak-valley electricity difference, transformer capacity, and electricity demand forecast, these equipment enable energy data visualization, flexible energy scheduling, energy cost optimization, and carbon emissions reduction based on the “double carbon” strategy.

· A total of 1,389,800 kWh was saved through smart air-conditioning, lamp replacement, basketball court/football field light source renovation, and underground garage light source adjustment. A total of 6,000 tons of water were also saved thanks to the renovation of the air-conditioning system.

Dahua’s overall energy consumption is continuously and reasonably reduced through management improvement, technological progress and industrial structure adjustment. Moving forward, Dahua will continuously focus on strengthening its energy management capabilities by delving deeply into the company’s potential in saving energy and reducing emissions as well as improving its resource utilization in order to better foster green living.
