Introducing rainfall interception layers.

Lengthening seepage pathways to drains.

Introducing low-transmissivity drainage layers.

Stormwater management effectiveness can be improved by introducing measures to enhance evapotranspiration.

For example, some research suggests that green roofs can improve building energy efficiency by lowering the temperature of air at the intakes for climate control systems.

Coordination of green roof design with the design of building heating, ventilation, and air conditioning (HVAC) systems can help to maximize operational cost savings.

Key Design Considerations for Green Roofs

May have limited Stormwater Retrofit feasibility for existing buildings and structures due to structural capacity issues.

More expensive to install than most conventional roofs.May need to be combined with other SMPs to meet the Flood Control requirement.Eligible for inclusion in an Expedited Post‑Construction Stormwater Management Plan (PCSMP) Review project.Assume less risk for projects within the floodplain.Can provide educational benefits, especially when used at public and/or highly visible sites such as schools, recreation centers, libraries, etc.

Can provide a reduction in landscaping requirements for parking areas, as per Philadelphia Code § 14-803(5)(e.2).Can be designed to provide spaces for recreation, supplement bird habitat, develop educational resources, and create new opportunities for urban food production.Extend the service life of the roof by protecting the underlying roof membrane from mechanical damage, shielding it from UV radiation, and buffering temperature extremes.Can improve air quality by filtering particulate matter.Reduce urban heat island effect by providing evaporative cooling.Help regulate building temperature in both the summer and winter, thus reducing cooling and heating costs.Enhance building aesthetics and market value.Promote the retention, slow release, and evapotranspiration of precipitation.Typically require no additional sewer connections besides those already provided for the building.Well-suited for sites at which roofs make up a large fraction of the total impervious area and for sites with ground-level space constraints.Manage stormwater runoff without occupying surface-level space.Learn more about this Credit Key Advantages of Green Roofs Installation of a green roof may also qualify a project for a Business Income and Receipts Tax (BIRT) Credit!
