How do green roofs and walls affect indoor air quality?

Green roofs and walls are becoming increasingly popular in urban environments as they offer a number of benefits, including improved indoor air quality. Green roofs and walls are surfaces covered with plants that help reduce pollutants and increase the oxygen content of the air. In this article, we will show how these green surfaces affect indoor air quality.

Green roofs

Green roofs are plant-covered surfaces placed on the roofs of buildings. These green surfaces have many benefits for indoor air quality. First, green roofs can reduce air pollutants such as carbon dioxide and nitrogen oxides. Plants absorb these pollutants during photosynthesis and produce oxygen instead. In this way, green roofs contribute to the inflow of fresh air and improve indoor air quality.

Secondly, green roofs can reduce the temperature inside the building. Plants provide shade and reduce the amount of heat that enters the building. In this way, green roofs help prevent overheating and the overuse of air conditioning systems, which often pollute the air.

Finally, green roofs can reduce noise levels in the building. Plants and soil layers absorb sound waves and reduce the penetration of outside noise. In this way, green roofs contribute to a calm and quiet indoor environment, which improves air quality.

Green walls

Green walls offer similar benefits for improving indoor air quality. These walls are covered with plants and located in the interior. First, green walls can reduce air pollutants, similar to green roofs. The plants absorb pollutants and produce oxygen, which improves indoor air quality.

Second, green walls can reduce the temperature inside the building. Plants provide shade and cool the air during evaporation. In this way, green walls help prevent overheating and overuse of air conditioning.

Finally, green walls can improve interior acoustics. The layers of plants and soil absorb sound waves and reduce internal noise levels. In this way, green walls contribute to a calm and quiet interior environment, which improves air quality.

Green roofs and walls therefore have a significant impact on indoor air quality. They help to reduce pollutants, improve the oxygen content of the air, and reduce the temperature and noise levels in the building. It is therefore worth considering the installation of these green surfaces in urban environments to improve indoor air quality and the health of occupants.
