Green roofs impact sustainability in several ways:
1. Reducing energy consumption: Green roofs act as insulators, reducing the amount of energy required to cool or heat buildings.
2. Absorbing rainwater: Green roofs absorb rainwater, reducing runoff and helping to prevent flooding.
3. Improving air quality: Plants on green roofs help to filter pollutants from the air, improving air quality.
4. Providing habitat for wildlife: Green roofs can provide habitat for birds, insects and other wildlife, contributing to biodiversity.
5. Reducing the urban heat island effect: Green roofs can mitigate the urban heat island effect, which is caused by the built environment trapping heat and causing temperatures to rise.
6. Increasing the lifespan of roofs: The layer of vegetation on green roofs provides protection against weathering, reducing the need for frequent replacements.
Overall, green roofs contribute to a more sustainable built environment by providing numerous environmental benefits.
