Against the backdrop of global advocacy of sustainable development, the green transformation of the construction industry has become an inevitable trend. As an important part of the building's exterior envelope, doors and windows have an important impact on the building's energy consumption, indoor environmental quality and ecological protection. With their environmentally friendly material selection, efficient energy-saving technology and recyclable characteristics, environmentally friendly doors and windows have become key green building materials to promote the sustainable development of buildings, creating a healthy, energy-saving and ecological living and working environment for people. ​

Environmentally friendly materials, protecting the ecology from the source​

The environmental characteristics of environmentally friendly doors and windows are first reflected in the selection of materials. In terms of frame materials, aluminum alloy is a common environmentally friendly choice. The aluminum used in aluminum alloy doors and windows can be recycled and reused, and the energy consumption in the recycling process is only 5% - 10% of the energy consumption of original aluminum production, which greatly reduces resource consumption and carbon emissions. During the production process, through surface treatment processes such as anodizing and powder spraying, the volatilization of harmful gases such as formaldehyde and benzene brought by traditional paints is avoided, ensuring indoor air quality. ​

Wood is also a commonly used material for environmentally friendly doors and windows, but more attention is paid to the sustainable source of wood. The wood for wooden doors and windows that meet environmental standards mostly comes from sustainable forests certified by the Forest Stewardship Council (FSC). These forests use scientific logging and cultivation methods to ensure the continuous regeneration of forest resources. At the same time, the wood is treated in an environmentally friendly way, such as using water-based paint to further reduce the release of harmful substances, so that wooden doors and windows retain their natural texture and meet environmental protection requirements. ​

In terms of glass materials, Low-E glass and hollow glass are widely used in environmentally friendly doors and windows. The surface of Low-E glass is coated with a low-radiation film, which can effectively block ultraviolet and infrared rays, reduce indoor heat loss and air conditioning energy consumption; the sealed air layer or inert gas in the middle of the hollow glass has good thermal insulation and sound insulation performance, reducing energy consumption during the operation of the building. These glass materials focus on energy conservation and emission reduction during the production process, and after the end of their service life, the glass can be recycled and processed to reduce the impact of waste on the environment. ​

Energy-saving technology, reducing building energy consumption ​

Energy saving is one of the core advantages of environmentally friendly doors and windows. Through advanced energy-saving technology, environmentally friendly doors and windows can significantly reduce the heating and cooling energy consumption of buildings. In addition to using energy-saving glass such as Low-E glass and hollow glass, environmentally friendly doors and windows are also very sophisticated in structural design. For example, the thermal insulation strips of broken aluminum doors and windows use thermal insulation strips to disconnect the aluminum alloy profiles and block the heat conduction path. Its thermal insulation performance is several times higher than that of ordinary aluminum alloy doors and windows; the design of multiple sealing strips enhances the air tightness of doors and windows, prevents air infiltration, reduces the exchange of hot and cold air indoors and outdoors, and further reduces energy consumption. ​

Some high-end environmentally friendly doors and windows are also equipped with intelligent control systems. Sensors monitor indoor and outdoor environmental temperature, humidity, light and other parameters in real time, and automatically adjust the opening state of doors and windows and the light transmittance of glass. In the hot summer, when the indoor temperature is too high, the doors and windows automatically close and adjust the glass to a low light transmittance state to block direct sunlight; in the cold winter, the doors and windows remain sealed, and the glass switches to a high light transmittance state, introducing sunlight to increase the indoor temperature and realize intelligent energy-saving control. ​

Multiple scene applications, practicing green concepts​

Environmentally friendly doors and windows are suitable for a variety of building scenes. In residential buildings, installing environmentally friendly doors and windows can effectively improve the indoor living environment. Reduce noise interference and create a quiet and comfortable resting space; reduce energy consumption, save household energy expenses, and reduce carbon emissions caused by energy consumption, contributing to environmental protection. For public buildings such as schools and hospitals, environmentally friendly doors and windows help create a healthy indoor environment, protect the health of teachers, students and patients, and reduce building operating costs, achieving a win-win situation of economic and environmental benefits. ​

In the field of commercial buildings, environmentally friendly doors and windows also play an important role. Large commercial buildings such as office buildings and shopping malls use environmentally friendly doors and windows to improve the energy-saving performance of buildings, meet green building certification standards, and enhance the market competitiveness of buildings. At the same time, good thermal insulation and sound insulation performance can also provide consumers and staff with a more comfortable environment, and enhance the quality and attractiveness of commercial places. ​

Purchase and development trends​

When purchasing environmentally friendly doors and windows, consumers should pay attention to the environmental protection certification of the products, such as China Environmental Labeling Product Certification, EU CE Certification, etc., to ensure that the products meet environmental protection standards. Check the energy-saving indicators of doors and windows, such as heat transfer coefficient, shading coefficient, etc., and choose products with excellent energy-saving performance. In addition, it is necessary to understand the material source and production process of doors and windows to ensure that the materials are sustainable and the production process is environmentally friendly.​

With the continuous advancement of science and technology and the enhancement of environmental awareness, environmentally friendly doors and windows will develop in the direction of higher performance, intelligence and integration. In the future, new environmentally friendly materials will continue to emerge, and the energy-saving performance of doors and windows will be further improved; deep integration with technologies such as the Internet of Things and artificial intelligence will realize intelligent control and management of doors and windows; at the same time, doors and windows will be integrated with other systems of the building to form a more efficient green building solution, injecting new vitality into sustainable development. ​

Environmentally friendly doors and windows have become the preferred choice of green building materials with their environmentally friendly materials, efficient energy-saving technologies and a wide range of application scenarios. Choosing environmentally friendly doors and windows is not only a pursuit of high-quality life, but also a responsibility for the earth's ecological environment. Let us work together to promote environmentally friendly doors and windows and jointly build a green, low-carbon and beautiful future home.
