Green Roof

Earlier this year, Manhattan Borough President Scott M. Stringer published a report entitled “Rooftop Revolution,” which proposes to install solar panels on the rooftops of New York City public school buildings.  The report estimates that installing solar panels on all of NYC’s public school roofs that could support them would increase solar capacity in the five boroughs by over 2,500 percent, eliminate approximately 76,696 tons of carbon from the air each year (the equivalent of planting over 400,000 trees), and could create an estimated 5,423 green collar jobs.

Building rooftops constitute 11.5 percent of the overall surface area in New York City, or approximately 944.3 billion square feet, an entire extra borough.  Consequently, rooftops have an enormous impact on the environment of the city and on the economics of owning and developing real estate.  The following article was published in the New York Law Journal on June 20, 2011, and discusses tax incentives, grant programs, zoning allowances and other laws and initiatives enacted at the federal, state and local levels to encourage the installation of sustainable roofs.  The article also discusses the impacts that a sustainable roof can have on a project seeking certification with the Leadership in Energy and Environmental Design ("LEED") program.

Earning LEED certification requires the accumulation of credits in a variety of categories.  The more credits a development or renovation project achieves, the higher the LEED rating the project will receive.  For some projects that seek LEED certification, the identification of “low-hanging fruits,” those easy to achieve and low-cost credits, can be a starting point in project planning.

One such credit, Sustainable Sites Credit 7.2: Heat Island Effect – Roof, awards points for installation of a roof with a high solar reflectance index (“SRI”), or a vegetated roof.  SRI is the measure of a surface’s ability to reflect solar heat – a standard black surface has an SRI of 0, while a standard white surface has an SRI of 100.
