The so called ‘Heat-Island-Effect’
which heats up the cities
and towns will be greatly reduced. GreenRoofs cool
the surrounding air through vaporization.
GreenRoofs reduce the energy consumption, GreenRoofs work
like an additional thermal insulation. The energy-equivalent of about
5 liters
oil / year / square meter can be saved.
During the summer and high outside temperatures the GreenRoof Layer gives an additional shade to the roof. The temperature
under GreenRoofs is about 5 degree lower.
Furthermore GreenRoofs coll through the vaporization of the water retained inside the soil and
the plants, advanced GreenRoof Systems have an internal air circulation. This means that the air conditioner can be switched down or even switched off.
During the winter and low outside temperatures GreenRoofs keep
the warm air inside the building, because the additional layers contain allot of
air which work like
a thermal insulation.
GreenRoofs retain a high proportion of rainwater and delay the
run-off even when fully saturated with water.
The increasing sealed surfaces caused by additional buildings,
roads and other paved areas leads to floods after heavy downpours.
GreenRoofs retain a high proportion of rainwater and delay the run-off even when fully saturated with water.
This ecological
benefit is also an economical advantage, because all the sewage water system can be reduced in size dramatically.
GreenRoof increase the life expectancy of the
building, the roof
is protected from UV-rays and changing temperatures.
