The roof of a building can be fully or part covered with a layer of vegetation known as a green roof.
Green roofs save energy.
Even when the weather turns cold green roofs still prove their usefulness by creating heat.
Accordingly the structure s air conditioning system doesn t have to work as hard.
Nearly two thirds of the savings come from reduced energy needs for the building below it.
Studies have shown that the membrane temperature beneath a.
Green roofs remove heat from the air through the process of evapotranspiration and also act as insulators for buildings reducing the energy needed to provide cooling and heating.
Buildings account for around half of primary energy consumption hence co 2.
Green roofs and energy performance.
Another important financial benefit.
Building energy savings and the potential for retrofit 1.
When it comes to cooling green roofs also help because natural plant and soil processes reduce the level of solar energy that is absorbed by the roof s membrane.
Green roofs do provide potential energy savings by improving building insulation.
Over its lifetime though the green roof would save about 200 000.
