Philadelphia Phillies / Renovations / Reflective and green roofs


The roofs of most buildings are black and absorb sunlight, warming the building and increasing the need for cooling during the summer. By coating your stadium’s roof with a light reflective surface, your team can reduce its energy use, saving both money and natural resources. Green roofs go a step further by planting vegetation that reduces summer cooling loads, absorb greenhouse gasses, and reduces water runoff.

When considering new construction or a renovation, ask your architects and suppliers and contractors about green and reflective roof options.

Environmental Benefits

Green and reflective roofs reduce energy consumption, mitigate air pollution, and help to lessen urban heat island effects. Less energy consumption means less global warming emissions less pollution, less acid rain, and fewer negative health and ecological effects associated with air pollution. Decreased stormwater runoff helps preserve stream habitats and prevent sewage overflows.
