American Psychological Association (APA) Headquarters Project of the Week: June 18, 2018

The American Psychological Association (APA) Headquarters is an outstanding example of corporate (in this case non-profit) social responsibility.  Its design choices for two properties in Washington, D.C. reflect fostering environmental sustainability on several fronts, especially with the incorporation of greenroofs during renovation (in addition to a utilities plan that uses 100 percent wind energy).

We are highlighting the American Psychological Association (APA) Headquarters in memory of Gregory Long of Capitol Greenroofs, who passed away in April.  His company installed both APA building greenroofs.  Greg was a fantastic individual and consummate professional whose belief in greenroofs as a means to create a healthier and more sustainable built environment is evident in all of his work.

The photo below during construction of the American Psychological Association (APA) Headquarters shows Greg and his team’s commitment to getting the job done, even during tough and challenging weather.

American Psychological Association (APA) Headquarters

Mini Description & Details

The American Psychological Association (APA) is the largest scientific and professional organization representing psychology in the United States. In an effort to reduce energy consumption, maximize recycling and contribute to a healthier environment, in April 2014 a second greenroof was added to APA properties at their headquarters (see the APA/World Resources Institute HQ from 2008), which qualified for the DDOE grant program.

In 2012, the Environmental Protection Agency rated both buildings in the top 10 percent of buildings in the U.S. with the lowest carbon footprint.

The design at the APA HQ building was focused on how greenroofs benefit people’s mental well being. Rebate funding was provided by the District Department of the Environment through a program administered by the Anacostia Watershed Society.

Many private companies were also involved which made this project successful. Installed by Capitol Greenroofs, the system design called for plenty of seating and relaxation with Bison Innovative Products decking tiles, metal planters, and perennial planting areas.

Composed of a mixture of perennials, woody shrubs and small magnolia trees set within modern style seating areas with bright decorative accents, this greened patio creates usable event space with spectacular views of the Capitol building.

In Memoriam: Gregory Long

June 18, 2018 at 5:45 pm

With a heavy heart, we share the recent passing of our wonderful, kind colleague, Greg Long.

Greg Long

Greg Long had an amazing, joyful spirit and energy and a shared devotion to creating sustainable design.  With a ready smile, he was always generous about sharing information and project experience. Greg touched so many people through the establishment of his design/build/maintain business, Capitol Greenroofs and its Group Site, an excellent discussion group forum.

“On April 28th, 2018 Greg Long passed due to complications of treatment for advanced cancer.  Many in the Washington, DC area knew him as a long term greenroof/greenwall promoter, designer, installer and owner of Capitol Greenroofs.

Greg grew up in Northern PA and went to Penn State University for a BA in Landscape Architecture.  After college he worked in the DC area at several engineering and architectural firms before catching the Greenroof bug and starting to promote these to anyone who would listen.  For 12 years he was a member of Green Roofs for Healthy Cities (GRHC) and was a certified Green Roof Professional (GRP).

Aside from work, he was an avid outdoorsman who liked to fish, camp, hike, snowboard, and float down river in any way possible.  Making friends whether at work or play was very important to him and he will be missed by many.” ~ Bob Long

Here are a couple of photos I took of previous CitiesAlive conferences:

Greg certainly will be missed by many within the Washington Metro Area, throughout North America, and beyond.  His high quality body of greenroof work will stand as a testament to his passion for living architecture.  Just some of his many projects include the American Psychological Association (APA) HeadquartersVirginia Commonwealth University (VCU) Pollak BuildingAmerican Psychological Association (APA)/ World Resources Institute (WRI) HQCity of Charlottesville City Hall/Police StationU.S. Tax Court, and the Herrity Building Parking Garage Demonstration Garden.

In Greg Long’s memory, we are featuring one of his outstanding works from 2014, the American Psychological Association (APA) Headquarters, as our current Project of the Week.

Greg didn’t search out the spotlight, and so I don’t have any more photos at the moment to share.  We would like to invite everyone interested to add your comments and send condolences below to Greg’s father, Robert (Bob) Long of Carolina Stonecrops.  Please  send photos to and I’ll add them to this post.

Greg will be sorely missed by and family and friends, and all of us within the greenroof community send our heartfelt condolences to his dad, Bob Long, and Greg’s loved ones.

Greg, may you rest in peace.
