The new Horticulture Center is very exciting for the Morris Arboretum and for the University of Pennsylvania as it is a prime example of the sustainability movement that we are seeing in modern architecture. Numerous systems and details of the building have been thought out, engineered and executed as we hope to achieve Platinum LEED certification. The Horticulture Center is environmentally friendly, aesthetically beautiful and a great place to work.
Over the last couple of days, we have been installing the green roof on the building and we have gotten some good press coverage as the green roof is a very visible green feature. A Green Roof is essentially a “living roof,” that – through plant cover –reduces a building’s absorption of ambient heat, thus keeping the interior cooler and more energy efficient. More information on the green roof can be found on the Horticulture Center webpage.
The roof is first prepared to receive vegetation with several different layers of waterproof, root blocking and drainage membranes. You can see the different layers in the photo below.
The medium is shipped on pallets and then hoisted onto the roof. The medium is the artificial soil in which the rooftop vegetation will grow.
After the medium is installed, the sedum is hoisted onto the roof in rolls like turf.
The jute is rolled back up and the sedum is then installed on top of the medium.
