State Grid Zhejiang Electric Power promotes energy conservation in public buildings by taking international standards as the starting point

On June 17, IEEE IAS (Institute of Electrical and Electronics Engineers for Industrial and Commercial Applications) officially released the technical standard "Guidelines for Energy-saving and Lightweight Transformation and Operation and Maintenance of Electrical Facilities in Existing Industrial and Commercial Buildings", which was led by State Grid Zhejiang Electric Power. The standard will provide clear technical specifications and implementation paths for lightweight and energy-efficient renovations of industrial and commercial buildings worldwide.

Public buildings are a key area of building energy consumption. According to the 2023 China Building Energy Consumption and Carbon Emissions Research Report, about 15 billion square meters of public buildings in China, accounting for only 21% of all building area, consume 42% of the building's operating energy, reaching 480 million tons of standard coal equivalent. Among them, the energy consumption level of urban commercial buildings is 10 to 15 times that of ordinary residential buildings. Reducing their high energy consumption has become an important part of achieving the "dual carbon" goals.

In response to the "pain points" of traditional renovation plans, such as significant structural damage and high costs, State Grid Zhejiang Electric Power Co., Ltd. has proposed a lightweight green, smart and low-carbon building renovation solution featuring "cloud-network integration, system integration, strategy symbiosis, multi-terminal linkage and holistic perception". This solution does not damage the structural decoration, does not affect normal office work, does not modify the original electrical facilities, the renovation cost is as low as about 15 yuan per square meter, and the renovation period for 20,000 square meters of buildings is within two weeks. The average energy-saving rate of the renovated buildings is over 20%, and the load regulation capacity is over 30%. This "small changes, big results" model quickly gained the attention of building owners, operators and power suppliers around the world, and was also recognized by the IEEE Standards Review Committee.

Under the impetus of State Grid Zhejiang Electric Power Co., LTD., the technical essence and normative requirements distilled from this successful practice have eventually been condensed into international standards. The standard elaborates on how to reduce lighting, implement flexible control of air conditioning temperature, and lower the power consumption of large electrical equipment, etc. It clarifies the overall technical requirements, software technical requirements, energy-saving control requirements, hardware technical requirements, etc., providing practical guidance for global building energy-saving renovations.

Mr. Rui, the executive director of the Standards Review Committee of the Institute of Electrical and Electronics Engineers, highly praised the standard, considering it the world's first standardized guidance document in the field of building electrical energy conservation, which is of great significance for improving global energy efficiency and promoting sustainable development.
