Original comment: Give full play to the leading role of the group standard in energy conservation and carbon reduction of commercial buildings

At present, the energy consumption of Beijing's construction sector accounts for about 50% of the total social energy consumption. Among them, commercial buildings and other public buildings account for only 20% of the total building area, but the proportion of energy consumption is more than 30%. It can be seen that commercial buildings are under great pressure in the dual control of energy consumption and carbon emissions in Beijing.

Commercial buildings have the characteristics of high floors, high floor area ratio, and a large number of elevators, stairs and other equipment, which lead to poor lighting and ventilation conditions, and at the same time, some buildings lack sufficient energy conservation and environmental protection considerations in the early design and construction process, resulting in low energy efficiency and becoming a "black hole" of energy consumption and carbon emissions. These buildings have poor thermal insulation performance and high energy consumption for heating in winter and cooling in summer, making the task of building energy conservation and carbon reduction more and more arduous.

At present, the electricity consumption of commercial buildings only accounts for 45%-75% of its total energy consumption, therefore, to achieve "dual control", it is necessary to promote the building energy consumption management from power consumption management to electricity, gas and heat consumption management as soon as possible. On the other hand, because the energy consumption of commercial buildings is relatively high, the space is larger, which has become the top priority for energy conservation and carbon reduction in the building field.

In order to promote the green and low-carbon transformation of the construction sector, the Office of the Beijing Municipal Leading Group for Carbon Peak and Carbon Neutrality issued the "Work Plan for Energy Conservation and Carbon Reduction of Beijing Civil Buildings and the Green Development Plan for Civil Buildings during the 14th Five-Year Plan Period" (hereinafter referred to as the "Plan"), which put forward the requirements of "carrying out research on the technical path of energy conservation and carbon reduction of civil buildings and achieving carbon neutrality, and organizing special research on carbon neutrality technology". How to implement the requirements of the "Planning", the author believes that the leading role of the group standard in energy conservation and carbon reduction of commercial buildings should be fully utilized.

The group standard cycle is short, and it can meet the needs of enterprises in a timely manner. Enterprises that attract investment or move into commercial buildings often need to meet green and low-carbon requirements when participating in bidding. Whether it meets the requirements of green and low-carbon requires an evaluation standard. It generally takes about two years to compile national standards and industry standards, and it generally only takes about 3 months to compile group standards, which shows that group standards can meet the needs of enterprises in a timely manner, and at the same time, enterprises can make their products and services based on evidence and improve their management level by participating in the formulation of group standards.

The starting point of the group standard is high, which can lead the high-quality development of the enterprise. National standards are required to be done by enterprises, which is a bottom line that must be complied with. The energy conservation and carbon reduction of commercial buildings to achieve carbon neutrality is the embodiment of the improvement of enterprises' awareness of ecological and environmental protection, and it is necessary to formulate group standards that are higher and stricter than national standards and industry standards to promote and lead enterprises to achieve this goal.

The standard of the group standard is high, which can enhance the competitiveness of the enterprise. There is a famous saying in the marketing world: "First-class enterprises do standards, second-rate enterprises do brands, and third-rate enterprises make products." "To be a standard is to raise the standard to a level that you can achieve but that your competitors are difficult to achieve, so as to gain the right to speak. By participating in the formulation of group standards, commercial buildings can use data to speak with data and indicators in energy conservation and carbon reduction to achieve carbon neutrality, and to make the numbers clear and accurate, so that they can stand out and gain competitive advantages in the process of attracting investment.

In the field of commercial buildings and other buildings, it is a new fashion in society to advocate energy conservation and carbon reduction to achieve carbon neutrality, and the characteristics of group standards conform to the requirements of the development of the times. Therefore, we should actively encourage and give full play to the leading role of group standards in promoting the realization of green and sustainable development of the economy and society.
