Learning New Things Related to Sustainable Living
GreenTreks Network has been lucky to have volunteer David Hecht on board since June 2012. Dave is working with GreenTreks Network as part of the GlaxoSmithKline Pulse Volunteer Program. Today, Dave is guest-blogging to share some of his recent experiences being in Philadelphia.
Over the years I have heard about the increase interest in the green infrastructure. We saw stories on television related to the greening of the Seattle and Portland, Oregon, areas. I am fortunate to volunteer through the GlaxoSmithKline Pulse program at GreenTreks Network Inc. They help tell stories that change the world. I have lived in Philadelphia over the last 3 months and have learned that this city is moving towards being a better sustainable city. Some private organizations have also been driven to this environmental goal. Over the last three weeks I have had a great opportunity to see two unique locations in the Philadelphia area. The first is at the Morris Arboretum and the second is the PECO office building in Center City Philadelphia. Both of the organizations have decided to work on having LEED-certified buildings.
The Morris Arboretum [featured in our Porous Pavement video] has a building that is Platinum-rated LEED Certified. Some of their buildings that impressed me were the green roofed storage/garage facilities. The two roofs grow different flora on them. The type flora grown is related to the depth of the soil. One roof is 2500 sq. ft with 4 inches of soil while the other is 3750 sq. ft with 8 inches of soil. Sedum is a typical growth since it is drought and temperature resistant.
A comparator roof is found on the 8th floor of the PECO building. This roof is much larger than the Morris roofs. It is 45,000 sq. ft of surface space with 4 inches thick with soil. It also has sedum and other flora growing on it.
The primary idea with having a roof with natural plant growth is stormwater management. The water that normally gets on roofs goes down the storm drain into our water supplies. Often there is waste or slit going in to the system along with the rain water. We know that we need to decrease the amount of runoff to help the waterways of our country.
With the videos that GreenTreks produces we help show stories like these to give others a positive educational experience.
