Some tips and tricks, and some random things we’re into. Two types of green roof exist: intensive and extensive. Green roofs are differentiated into intensive and extensive green roofs. ABSTRACT Green roofs have good heat preservation and insulation performance, which plays an important role in reducing air-conditioning load and reducing carbon dioxide emissions. The roof structure is an important consideration in green-roof design. Semi-intensive roofs, combinations of both extensive and intensive green roofs, are typically adopted to harness both the environmental benefits of a green roof, as well as a diverse garden within a … Domestic & Commercial.

Benefit: Green roofs are energy efficient. Organic materials are usually kept to a maximum of 20%. A green roof also can be installed over an existing roof, provided the underlying roof structure and membranes are in sound condition. Data collected from a study by researchers at the Pennsylvania State University, Center for Green Roof Research show that green roofs captured up to 80% of rainfall during rainstorms, compared to 24% typical for standard roofs. Green roofs can help reduce energy costs for a building by acting as another layer of insulation between the inside and outside of the roof. And the cost? While policies that encourage green roofs exist at the local and regional level, installation costs remain at a premium and deter investment in this technology.
