We recently came across this piece by Brittany Patterson at E&E Publishing on green roofs in the nation’s capital and their enormous (and necessary) benefits, which was originally published behind E&E’s paywall. E&E, which does excellent daily reporting on climate change and energy issues, has kindly allowed us to repost the article in full.
NATION’S CAPITAL BECOMES GREEN ROOF CAPITAL TO FIGHT EXTREME HEAT, HEAVY STORMS
BRITTANY PATTERSON, E&E PUBLISHING, LLC, JUNE 9, 2015
Nestled on Eye Street in downtown Washington, D.C., near the heart of the bustling city lies the headquarters of the American Society of Landscape Architects (ASLA).
From the front, the brick building looks like any other in the neighborhood, but take the elevator and a flight of stairs to the roof and you’ll find yourself surrounded by rows of green Sedum, blooming prickly pear cactus, and patches of lush butterfly milkweed and hare’s-foot clover. It’s almost possible to imagine you are sitting in the tranquil countryside, not just on the roof of a building covered in foliage.
As relaxing as they can be, green roofs are more than just easy on the eyes.
“Green roofs deliver multiple benefits for both combating heat and in the retention of stormwater,” said Kate Johnson, a program analyst with the District Department of the Environment (DDOE). “Both are issues we think are going to continue to be important in light of climate change. It’s projected to get hotter, and it’s projected we’ll have more extreme rain events.”
