See the MassDEP Stormwater Handbook, Volume 2 for information. Stormwater Design Quantity Control: MassDEP encourages green roofs by allowing the water quality volume required to be captured for stormwater treatment to be reduced, provided the green roof is sized properly.Costs Associated with Green Roofsīuildings with Green Roofs may be able to obtain LEED Certification in a number of different categories: Green roofs are good public relations for business promotion.īusiness information can be found by reading "The National Decentralized Water Resources Capacity Development Project", a publication produced by US EPA and the Water Environment Research Foundation.May increase retail sales and building occupancy rates, and.May improve employee satisfaction and worker productivity,.Green roofs may be good for business and public relations:

East Office Building at the World Trade Center in Boston, MA.

Reducing the heat island effect in densely developed areas.Įxamples of green roofs created to improve the quality of life:.

Enhancing public health by reducing pollution and by providing additional areas for passive recreation, such as walking or wildlife observation, and.

Reducing noise from machinery traffic and airplanes,.

Green roofs can improve the quality of life: When incorporated into a combined sewer overflow abatement strategy, green roofs can reduce the need for sewer separation or storage projects required to reduce the volume and frequency of combined sewer overflows.The plants and growing medium of a green roof absorb water that would otherwise become runoff, and research indicates that peak flow rates are reduced by 50 percent to 90 percent compared to conventional roofs. Green roofs can improve stormwater management.Green roofs can remove carbon dioxide and produce oxygen. Green roofs can remove particulate matter and gaseous pollutants including nitrogen oxides, sulfur dioxide, carbon monoxide, and ground level ozone from the air. The plants in a green roof can remove certain pollutants from the air.By reducing roof temperatures, green roofs slow the formation of ground-level ozone.By reducing energy demand, green roofs reduce the air pollution and greenhouse gas emissions associated with energy production.Green Roofs reduce air pollution and greenhouse gas emissions while improving stormwater management Solar panels may compete with green roofs for use of the roof space, but have been found to increase the energy efficiency of green roofs.Cool roofs may be combined with green roofs for optimum use. Cool roofs do not provide the stormwater management and quality of life benefits associated with green roofs. Cool roofs provide similar energy savings to green roofs and are cheaper. Cool roofs - light colored roofs that reflect rather than absorb heat - are an alternative to green roofs.
