Washington, D.C. LEED-CI (version 2.0) Platinum


Group Goetz Architects (GGA) was awarded LEED Platinum certification by the USGBC for the design of its corporate offices in Washington D.C.'s Georgetown neighborhood. As the first Washington-based design firm to achieve this prestigious designation, GGA continues to serve as a sustainability leader by incorporating sustainable design principles into each of its projects.

To establish its continued commitment to green building, GGA's design complements the evolving culture of the American workplace. The new, 16,000-square-foot office has a completely open floor plan zoned by a "main boulevard" which runs the full length of the office. This spine separates a high-tech conference center, library and employee lounge from the firm's design studio. The studio contains spacious communal workspaces for both executives and staff, which encourages employee communication and peer relationship building.

The firm's employees enjoy the benefit of 100 percent natural light penetration as well as daylight controlled lighting and individual temperature controls. The open layout and glass exterior also lower energy consumption by reducing the need for artificial and engineered lighting. To improve accessibility to alternative transportation, GGA employees enjoy access to metro, car sharing, shuttle service, and bike racks.

"LEED Platinum certification further demonstrates our commitment to sustainable environments for our employees and clients alike," notes Lewis Goetz, FAIA, FIIDA, president and CEO of the firm.

GGA achieved 43 points out of the minimum 42 points required to receive the Platinum rating. A number of green design features contributed to this score, including:


  • Reduced lighting power by more than 35 percent through energy-efficient lighting and lower lighting density
  • State-of-the-art lighting controls that are influenced by sunlight and occupancy reduce energy consumption
  • Enhanced commissioning to ensure building systems are operating at optimal efficiency


  • Recycled more than 75 percent of construction waste
  • More than 20 percent of materials had post- consumer recycled content
  • More than 10 percent of materials were manu- factured regionally within a 500-mile radius
