Project Description

The American Psychological Association (APA) is the largest scientific and professional organization representing psychology in the United States. APA is the world’s largest association of psychologists, with nearly 130,000 researchers, educators, clinicians, consultants and students as its members. Their mission is to advance the creation, communication and application of psychological knowledge to benefit society and improve people’s lives. In April 2014, the APA made an effort to reduce energy consumption, maximize recycling and be more environmentally conscious. As part of this initiative, they added a green roof to their headquarters.

The new rooftop uses Bison Innovative Products ipê decking tiles for a warm natural look, Bison Cube planters complete with perennial plants and plenty of seating for employees to relax. In another area, Bison Cubes were used in a custom installation as planters with built-in ipê benches. This patio creates usable event space with spectacular views of the Capitol building in Washington DC. The wood decking tiles by Bison contrast the stone pavers and a steel trellis provides ample shade for the area. The building has the honor of being one of the top 10% of buildings in the US with the lowest carbon footprint.
