Green Roofs Save Energy

Another important financial benefit.

Green roofs save energy.

Even when the weather turns cold green roofs still prove their usefulness by creating heat. 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. The study looked at a range of benefits of green roofs including stormwater management improved health benefits due to reduced pollution and energy savings.

Buildings account for around half of primary energy consumption hence co 2. 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. The roof of a building can be fully or part covered with a layer of vegetation known as a green roof. Building energy savings and the potential for retrofit 1.

Accordingly the structure s air conditioning system doesn t have to work as hard. Over its estimated lifespan of 40 years a green roof would save about 200 000 of which nearly two thirds would come from reduced energy costs. Green roofs and energy performance. Over its lifetime though the green roof would save about 200 000.
