Strengthening of Building Energy-saving Policies, Energy-saving Door Closers Become Mandatory Configuration

With the full implementation of the "General Code for Building Energy Conservation and Renewable Energy Utilization", energy-saving door closers have become a mandatory configuration requirement for public buildings, and their role in reducing building energy consumption and optimizing the indoor climate has become increasingly prominent. Data shows that the installation of qualified energy-saving door closers can reduce building door and window energy consumption by 15%-20%, helping buildings achieve green certification goals.
The core advantages of energy-saving door closers are reflected in two aspects: airtightness and energy efficiency design. In terms of airtightness, by optimizing the connection structure between the door closer and the door body, combined with high-efficiency sealing strips, the sealing performance of the door body after closing can be improved by 30%, effectively blocking the air circulation between the inside and outside of the building, and reducing air conditioning energy consumption and heat loss. In winter, it can reduce the indoor temperature loss rate by 25%; in summer, it can reduce cold air leakage and improve the air conditioning operation efficiency by 18%. In terms of energy efficiency design, intelligent energy-saving door closers can automatically adjust the operation mode according to the frequency of use, maintaining a high airtight state when no one is using them, and switching to an efficient traffic mode during peak hours, reducing energy consumption by more than 40% compared with traditional products.
At the policy level, the green building evaluation standard clearly requires that door closers in public areas must meet the energy-saving level of Grade II or above. Some cities have included the configuration of energy-saving door closers into the mandatory indicators for building energy conservation acceptance. In government-invested projects, indemnificatory housing, and green building certification projects, the application rate of energy-saving door closers has reached 100%. To promote the energy-saving transformation of the industry, relevant departments have also introduced policy dividends. Door closer products using low-energy consumption and environmentally friendly materials can enjoy tax incentives and priority in green procurement. Industry enterprises are accelerating technological research and development, and further improving the energy-saving performance of products by using lightweight materials, optimizing hydraulic system design, and integrating energy-saving control modules. It is expected that by 2025, the penetration rate of energy-saving door closers in newly built buildings will reach more than 90%.
