OK, the picture you see doesn't have a green roof, but the green roof is there, really! According to "Capital Gains," the Township of Delhi, near Lansing, Michigan put a 7200 square foot green roof on the Sam Corey Senior Center.
The Senior Center, in addition to having a green roof, also has "...a geothermal closed-loop ground source heat pump." Additionally, it is the first LEED-certified building in the Township. The Township decided to use the green roof to mitigate storm water runoff and reduce HVAC costs. The Township estimates the green roof will absorb 9/10 of an inch of rain and save 35-50% in HVAC costs. $20 Off AeroGardens
The green roof was built using elements from LiveRoof. Headquartered in the Netherlands, LiveRoof uses a modular system, making installation and maintenance easy. Similar to flats of annuals, if changes need to be made or changes in the design are desired, it is simple as replacing the flat.
As I mention in the title section of the blog, green roofs provide tremendous cost and environmental benefits without being overly complex or expensive. Were I a taxpayer in Delhi Township or the state of Michigan, I would congratulate the responsible parties for wise use of my tax dollars.
