Moderation of Urban Heat Island Effect
- Through
the daily dew and evaporation cycle, plants on vertical and horizontal
surfaces are able to cool cities during hot summer months and reduce the
Urban Heat Island (UHI) effect. The light absorbed by vegetation would
otherwise be converted into heat energy.
- UHI
is also mitigated by the covering some of the hottest surfaces in the
urban environment – black rooftops.
- Green
roofs can also help reduce the distribution of dust and particulate matter
throughout the city, as well as the production of smog. This can play a
role in reducing greenhouse gas emissions and adapting urban areas to a
future climate with warmer summers.
