Higher Education: Messaging with Green Roofs
By Nancy Grundahl
2012 marks the 40th anniversary of the Clean Water Act, the nation’s law for protecting our most irreplaceable resource. Throughout the year, EPA will be highlighting different aspects of the history and successes of the Clean Water Act in reducing pollution in the past 40 years. The month of May will focus on Clean Water, Jobs, and the Economy.
Green roofs have much to offer.
- They hold rainfall that would otherwise run over impervious surfaces carrying pollutants to our streams.
- They act as magnificent insulators, significantly lowering the HVAC needs of a building.
- They provide habitat for birds and insects such as butterflies and bees.
- And, some may provide a park-like escape for people working in the building.
So, it’s no surprise that green roofs are gaining in popularity. And, it figures that someone would start designing green roofs to be like works of art or to convey a company’s message. I don’t mean by using signs or statues, but by using plants and soils with different colors and textures.
It makes sense. There’s an audience out there – or, rather, up there. People in nearby taller buildings, pilots and their passengers. There were 448,129 aircraft takeoffs and landings at Philadelphia International Airport in 2011. Multiply that by the number of people with window seats and you get a tremendous number of potential onlookers.
So, we’re calling on all “higher-ups.” Have you seen green roofs that you’d like to tell us about?
