    The Changing Tide of Green Roofing Systems in the USA

    February 1st, 2017

    According to a recent a recent report, San Francisco may be first US city to require green roofs on new buildings.

    30 percent of all the land area in San Francisco is comprised of rooftops, but most are under-utilised, according to the San Francisco Planning Department. City supervisor Scott Wiener is offering a solution that builds on the measure passed earlier this year to require rooftop solar. If new legislation introduced September 6 is approved, San Francisco would be the first city โ€œto pass requirements for green roofs.โ€

    The San Francisco Planning Commission unanimously approved the legislation Wiener introduced. The existing solar mandate requires 15 percent of rooftops on buildings with 10 stories or less to include solar panels. The new legislation would go a step further: 30 percent of new roofs could be turned into green roofs or a blend of green roof and solar panels. Owners could include two square feet of living roofs or a blend of living roofs and solar as opposed to one square foot of rooftop solar panels. According to Green Roofs for Healthy Cities, their 11th Annual CitiesAlive Conference, hosted in San Francisco in 2013, helped inspire the legislation.
