Unlike traditional black tar roofs green roofs reduce energy costs by absorbing heat instead of attracting it and.
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 are energy efficient.
The study looked at a range of benefits of green roofs including stormwater management improved health benefits due to reduced pollution and energy savings.
Green roof designed for biodiversity and to generate solar electricity photo.
But in fact both systems can benefit each other too.
Both sod roofs and lwa based lightweight aggregates roofs have been found to have a negative impact on the quality of their resulting runoff.
Green roofs reduce the heat flux through the roof and less energy for cooling or heating can lead to significant cost savings.
This value is equivalent to 6448 g c m 2 which is significantly greater than 378 g c m 2.
The plants create natural insulation which means that there is less need to rely on heating and cooling systems to moderate interior temperatures.
