In 2009, PECO unveiled two eye-catching upgrades to its iconic Main Office Building in center city Philadelphia. The first was an acre of vegetated roof that now manages 1.5 million gallons of rainwater and hosts an average of 1,000 visitors each year. While stormwater absorption stands as the principal environmental benefit provided by a vegetated roof, numerous other benefits are also accrued, including reduction of summertime ambient air temperatures, air cleansing, protection of the roof membrane so as to prolong its life, better comfort for those in the spaces below the roof, a new habitat for birds, insects and other wildlife, and adds undeniably beauty to the cityscape. To the thousands of city occupants who visit and look down upon the roof, it serves as a reminder that the roofs of our existing buildings can be transformed into amazing natural environments. This project was completed with frequent Re:Vision collaborator, Roofmeadow.
As part of a July 4th celebration, PECO also reintroduced their scrolling ‘Crown Lights’ as energy efficient light emitting diodes (LEDs).
These design changes were inspired by PECO’s larger LEED for Existing Building certification process.
