Green roofs are more than just a lush tool for stormwater management. Green roofs have other benefits such as the potential to bring forth a bountiful feast to pollinators. Pollinators are critical to our survival making it possible for grow the crops that feed our hungry nation and aiding in the replication of vegetation which purify our air and bodies of water. Pollinators include a variety of areal insects as well as a few birds and bats.
A shining example of this style of green roof we have worked on is the Hamerschlag Hall at Carnegie Mellon. Hamerschlag Hall features extensive and semi-intensive green roof areas with a variety of ground covers and tall grasses. Herbaceous plants and sedums provide food while an array of evergreens creates opportunities for shelter.
On the rooftop of the Resource Conservation Technology Ice House we created a garden specifically for honey bees. Fragrant drought tolerant herbs and bulbs bloom from February to November creating both seasonal interest and a consistent food source.
