In recent years, ultra-low energy consumption buildings are often mentioned, especially the rapid development of energy-saving buildings. Passive houses originated in Europe have developed rapidly in China. With advanced materials and unique technology, passive house has improved building energy efficiency, living quality and atmospheric environment. It has greatly reduced the energy consumption of buildings and promoted the transformation and upgrading of traditional door and window manufacturing industry.

What is passive room?

The five core technologies of passive room include: energy-saving and thermal insulation system, high-performance door and window system, avoiding cold and hot bridge design, excellent air tightness design, and efficient heat recovery fresh air system. Through its own thermal insulation system and heat recovery system, passive house can not only greatly reduce building energy consumption throughout the year, but also achieve the effect of energy saving and consumption reduction, driving industrial transformation and upgrading and improving the quality of national life.

Because of this, many national policies on building energy conservation and ultra-low energy consumption buildings have been issued, which means that the state will put more energy into the ecological environment protection. When the haze weather or extreme weather occurs, the passive room can still maintain the room temperature in the four seasons at a suitable temperature, keep the indoor air clean and improve the indoor health level of the building.

Among them, in June this year, Handan Municipal Bureau of housing and urban rural development issued the implementation opinions on promoting the development of ultra-low energy consumption buildings (Draft for comments), comprehensively launched the pilot work of ultra-low energy consumption buildings, and promoted the promotion of ultra-low energy consumption buildings in the form of awards and subsidies. The plot ratio of ultra-low energy consumption buildings was awarded 9%, and the maximum subsidy was 12 million yuan.

At the same time, Baoding housing and Urban Rural Development Bureau issued Baoding green building special plan (2020-2025). The special plan introduces the development status of ultra-low energy consumption buildings in the city, and plans the overall goal, target decomposition and technical route of ultra-low energy consumption buildings in five years. It looks forward to vigorously promote the construction of passive ultra-low energy consumption buildings by 2035 8 million square meters of passive ultra-low energy consumption construction projects.

At the beginning of July, a new standard for residential buildings in Beijing was issued, with the residential energy saving rate increased from 75% to more than 80%. The standard will be formally implemented on January 1, 2021. Recently, Hunan Provincial Department of housing and urban rural development issued the "passive ultra-low energy consumption residential building energy saving design standard (Draft)", actively promoting the development of urban green buildings, strengthening the energy-saving demonstration and leading, and promoting the development of green buildings Resource saving and utilization.

In the face of increasingly serious energy crisis and environmental pollution, passive ultra-low energy consumption green building has become an important way to effectively deal with climate change, energy conservation and emission reduction. Its market potential is huge, and it is becoming the development trend of global building energy conservation. Doors, windows and curtain wall enterprises should follow the trend, take the initiative to take social responsibility, be a good protector of ecological environment, and comply with the world's green, green and green buildings Healthy and sustainable development trend, continuous research and development of high-performance door and window system, and actively promote the development of ultra-low energy consumption buildings.
