Building energy-saving materials

With the continuous improvement of people's awareness of environmental protection, building energy efficiency has become an issue that cannot be ignored. Building energy-saving materials is an important means to improve the efficiency of building energy use, can effectively reduce the building's energy consumption, reduce the pollution of the environment, but also can provide people with a more comfortable and healthy living environment.

Types of building energy-saving materials

Building energy-saving materials include a variety of aspects such as walls, roofs, doors, windows and floors. Among them, the common building energy-saving materials are:

1. Heat-insulating materials: heat-insulating materials can effectively reduce the heat loss of the building and make the indoor temperature more stable. Common thermal insulation materials are polystyrene board, rock wool board, glass wool and so on.

2. Soundproofing materials: soundproofing materials can reduce noise interference inside and outside the building, improve people's living comfort. Common sound insulation materials are sound-absorbing boards, soundproof felt, etc..

3. Glass: the use of low-e glass can effectively reduce the building's energy consumption, but also reduce ultraviolet radiation, to protect people's health.

4. Cement: the use of high-strength cement can improve the structural strength of the building and reduce the cracks and deformation of the building.

How to choose building energy-saving materials

Selecting building energy-saving materials requires consideration of a variety of factors, including the use of the building, geographic location, climatic conditions and so on. When choosing building energy-saving materials, you need to pay attention to the following points:

1. Functionality: building energy-saving materials need to have a variety of functions such as heat insulation, sound insulation, waterproofing and so on.

2. Durability: building energy-saving materials need to have a long service life, able to withstand a variety of natural environments.

3. Environmental protection: building energy-saving materials need to meet the environmental requirements, will not cause pollution to the environment.

4. Economy: building energy-saving materials need to have a reasonable price to meet the energy-saving requirements of buildings, while not increasing construction costs.

Application cases of building energy-saving materials

Building energy-saving materials have been widely used, the following are a few cases of application of building energy-saving materials:

1. Application of heat-insulating materials: In Germany, there is a building called "Kangaroo House", which uses polystyrene board as the The use of polystyrene boards as insulation material allows the indoor temperature to be maintained at about 20℃, even in the cold winter without turning on the heater.

2. Application of soundproofing materials: In the United States, there is a building called "Music House", using sound-absorbing panels as soundproofing materials, so that the sound of indoor music can get the best propagation effect.

3. Application of glass: In China, there is a building called "Green Office Building", using low-e glass as window material, making the building's energy consumption reduced by more than 30%.
