Existing Public buildings The situation of energy conservation is expected to be improved. The whole society's awareness of energy conservation has raised the pressure on non energy efficient buildings. Thanks to the government's energy conservation and emission reduction work for many years, the whole society has reached a consensus on the macro level concepts of energy conservation, efficiency improvement, environmental protection and nature protection, and more enterprises choose to deeply cultivate green buildings; Investors, construction users, etc. pay more attention to the rating of environment, social responsibility and corporate governance (ESG); Individual employees also pay more attention to low-carbon behaviors. These changes have created a good environment for influencing and promoting more building owners and tenants to take energy-saving actions. In such an atmosphere, if the policy can provide effective energy conservation action guidance, it is expected to receive higher social responsiveness than before.
The intensification of business type adjustment and batch aging of equipment bring an important window period for energy conservation of existing public buildings. The slowdown of China's economic growth and Sino US trade frictions have affected most of the existing economic formats. At the same time, the concept of e-commerce economy and sharing also has a certain impact on the traditional business model that relies on physical public space. These factors have accelerated the adjustment frequency of commercial formats. For example, to transform a poorly managed mall into an office building, functional adjustment needs to be done accordingly. In addition, since the effective service life of HVAC equipment commonly used in commercial buildings, such as refrigerators and water pumps, is generally about 20 years or even shorter, and since 2000, it is the period when a large number of public buildings were constructed and put into use, which means that a large number of existing large-scale public buildings across the country are ushering in an intensive equipment replacement period. The adjustment of business types and the end of the service cycle of equipment provide objective benefits for the transformation of commercial buildings. However, making full use of these important opportunities and doing a good job in policy guidance can achieve twice the result with half the effort.
In order to resolve the dilemma of energy conservation in existing public buildings and help China achieve the goal of carbon emission peak and high-quality development of the construction industry at an early date, the report suggests that the competent department should first change the policy guidance idea, abandon the previous ideas of financial subsidies and economic stimulus, and instead advocate and commend the improvement of the social responsibility awareness of owners and enterprises, So as to encourage them to take more environmental responsibilities. At the same time, since the building overhaul is an opportunity to promote the owners to adopt energy-saving measures, it is suggested that the competent department should conduct troubleshooting, master the overhaul plan of large public buildings, and guide the owners to take the overhaul as an opportunity to improve building energy efficiency. At the technical level, the report proposed the concept of comprehensively promoting the energy efficiency improvement of subsystems, from focusing on the energy efficiency of single equipment such as pumps and refrigerators to focusing on the overall energy efficiency of refrigeration systems and fresh air systems, providing support for the next step to promote the overall energy efficiency improvement of buildings. In addition, in view of the fact that the energy-saving equipment, products, system solutions and service levels of domestic enterprises have gradually caught up with those of well-known international enterprises, the report also suggests that the competent authorities should vigorously support the rapid development and growth of domestic enterprises, thus promoting China's energy-saving technology to enter the international leading ranks.
