Green Roofs Save Energy

Building energy savings and the potential for retrofit 1.

Green roofs save energy.

Nearly two thirds of the savings come from reduced energy needs for the building below it. The roof of a building can be fully or part covered with a layer of vegetation known as a green roof. 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. Even when the weather turns cold green roofs still prove their usefulness by creating heat.

Green roofs and energy performance. Another important financial benefit. Over its lifetime though the green roof would save about 200 000. 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. Green roofs do provide potential energy savings by improving building insulation. Green roofs benefits improved energy performance temperature of waterproofing membranes under green roofs. The study looked at a range of benefits of green roofs including stormwater management improved health benefits due to reduced pollution and energy savings.
