How passive cooling of buildings reduces the need for air conditioning

  • In a statement, the UK’s Energy and Carbon Senior Research Fellow said that 80% of homes could be affected by overheating by 2022, and that the rest of the homes might be affected by overheating in the future.
  • The researchers explain that the reason for this is that air conditioning systems are not used, and that the temperature in buildings is not controlled.
  • Publications about the USA and Europe point out that the increase in the number of buildings can be due to the fact that the climate is changing.

In the materials it is stated that the greater the effectiveness of building insulation, the less likely it is that overheating will occur, and the more likely it is that the temperature will remain stable. Therefore, it is important to use passive cooling methods to reduce the need for air conditioning.

According to the materials, published by Velikobritaniya, two-thirds of homes could be affected by overheating by 2022. The materials also note that 80% of homes in the UK could be affected by overheating by 2022, and that in the end the temperature could rise by 40°C.

The materials also explain that the reason for this is that the temperature in buildings can rise due to the fact that the air is not cooled. In 2022 to 2023, researchers found that in the UK, the number of days with overheating could increase significantly, which could lead to overheating of buildings. In this regard, it is possible that the use of passive cooling methods could help reduce the risk of overheating.

In a publication, it is stated that “reduce cooling demand first” — a strategy to reduce the need for air conditioning, and then to use more efficient cooling methods. As applied to passive cooling, this means that instead of relying on air conditioning, it is necessary to reduce the amount of heat entering buildings. This can be achieved by using measures such as insulation, shading, and ventilation, as well as by using passive cooling systems.

However, it is important to note that the effectiveness of passive cooling methods depends on factors such as the climate and the type of building. The researchers also say that passive cooling can be achieved through the use of “cool roofs” and other technologies that help reduce heat absorption.

In addition, the researchers note that the study was conducted in Phoenix and that the results show that passive cooling measures can help reduce heat exposure. In particular, the authors say that the use of “cool roofs” can reduce the risk of overheating and improve comfort in homes.
