Energy-saving doors and windows for priority use in social housing

The Ministry of Housing and Urban-Rural Development has recently issued a notice to mark the energy-saving performance of the main products of door and window companies above the national scale in about three years. The marked doors and windows are widely used in new buildings and energy-saving renovation of existing buildings.

It is understood that China's annual production and application of doors and windows are large, and the energy consumption of doors and windows accounts for about 50% of the energy consumption of building envelopes and 25% of the total energy consumption of buildings. The door and window marking system can provide a reliable basis for building energy-saving design, engineering quality supervision, and guiding consumption.

The Ministry of Housing and Urban-Rural Development requires that, for office buildings and large-scale public buildings constructed with financial investment, as well as affordable housing projects, priority should be given to doors and windows that have obtained energy-saving labels; Performance index requirements should be based on the information of doors and windows.
