Green Roof Technology at Catoctin Creek Park

It may have snowed this morning, however I thought it would be nice to showcase another new "Green" technology at Catoctin Creek Park and Nature Center. Catoctin Creek Nature Center will be the first Frederick County building to have a "Green Roof". Many benefits can be achieved with virtually all green roof infrastructure systems. Below are a couple of the economic benefits that the Nature Center may experience with this system.

1. Protection of roof membrane resulting in a longer material lifespan (it is estimated that green roofs will last up to twice as long as conventional roofs), resulting in decreased maintenance and savings in replacement costs.

2. Savings on energy heating and cooling costs, depending on the size of the building, climate and type of green roof. Environment Canada found that a typical one floor building with a grass roof and 10 cm (3.9 inches) of growing medium would result in a 25% reduction in summer cooling needs. Field experiments by Karen Liu in Ottawa Canada, found that a 6 inch extensive green roof reduced heat gains by 95% and heat losses by 26% compared to a reference roof.

The new Nature Center will have access capability for supervised school groups and program participants to visit the roof and learn first hand what Green Roof technology is all about.

  1. This is fantastic, green roofs have so many benefits and hopefully this will inspire other companies and organizations to do the same! Best of luck to you.
