Extensive green roof energy consuption.

Green roofs are energy efficient. Green roofs improve and reduce energy consumption. 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. A green roof also known as a rooftop garden or a living roof is a vegetative layer grown on a rooftop.

Installing green roofs can reduce the negative impact of development while providing numerous environmental economic and social benefits. Green roofs reduce the heat flux through the roof and less energy for cooling or heating can lead to significant cost savings. The popularity of green roofs has increased in the united states due to their many benefits while pretty green roofs serve a much greater purpose than simple beautification. 8 to 20 per square foot.

Green roof temperatures can be 30 40 f lower than those of conventional roofs and can reduce city wide ambient temperatures by up to 5 f. Unlike traditional black tar roofs green roofs reduce energy costs by absorbing heat instead of attracting it and. And a plant covered roof 85 degrees. Energy performance is a key benefit of green roofs.

1 2 in addition green roofs can reduce building energy use by 0 7 compared to conventional roofs reducing peak electricity demand and leading to an annual savings of 0 23 per square foot of the roof s surface. 1 3 these temperature reduction and. They can reduce heating by adding mass and thermal resistance value also can reduce the heat island by increasing evapotranspiration. Shading the outer surface of the building envelope has been shown to be more effective than internal insulation.

Thermal reduction and energy conservation. Whilst green roofs are important for cooling cities as a whole a green roof can roof can also have a positive impact on the energy balance within any given building this is particularly relevant if a building has poor insulation and poor ventilation. There are many modular green roof kits available that might bring the costs down. A 2005 study by brad bass of the university of toronto showed that green roofs can also reduce heat loss and energy consumption in winter conditions.
