Restoring a national historic landmark as an example for sustainable design

A practical, visible demonstration of the Friends’ commitment to “treading lightly on the Earth,” this project is a model of energy conservation and sustainable design. Friends Center, in the heart of Philadelphia, has been a locus of Quaker worship and action for 150 years. It spans 1.26 acres and includes the historic Race Street Meetinghouse built in 1856—a National Historic Landmark—as well as a 56,000 sq. ft. office building erected in 1972.

The office building achieved LEED Platinum certification, with highest number of LEED points in Pennsylvania at the time of completion. The historic Meetinghouse was renovated to the same standard. Two goals governed the renovation: eliminate fossil fuels and greenhouse gas emissions, and reduce water usage and storm water runoff. Friends Center now uses a geothermal system for heating and cooling. A photovoltaic array provides supplemental electricity. A vegetated roof and rain water storage/ collection system capture water for plumbing while protecting the watershed from excessive runoff. An aggressive plug load policy reduces energy use.
