UPDATE: January 2005 – This project was recently awarded a Silver Rating under the U.S. Green Building Council’s LEED Commercial Interiors Pilot Rating System.
Other awards received since opening in 2002 include:
-- International Interior Design Association (IIDA) Mid-Atlantic Chapter: Best Sustainable Design
-- AIA Washington Chapter: Presidential Citation for Sustainable Design
-- Environmental Design + Construction magazine: First Annual Excellence Award
-- Contract magazine: Interiors Award in Green Design
Environmental Defense is a nationally recognized environmental organization known for its ability to work closely with major corporations in developing environmentally responsible solutions to problems. The client charged Envision Design to create its Washington, DC, office as a model for the organization’s environmental values. The 16,144-square-foot space on the sixth floor in an existing high-rise is filled with natural light, healthy for the staff, built on a reasonable budget – and has minimal impact on the environment.
“This was an aggressively environmental and visually sophisticated interiors project,” says Ken Wilson, AIA, Envision Design’s Principal-in-Charge. “When we started out on a sustainable path three years ago with the design of the Greenpeace USA headquarters (our first project as a firm), we looked at other ‘green’ spaces and were not impressed. They all seemed a little, well, bland. But you don't have to give up having a beautiful space by making it green – and you get so much back.”
From the moment visitors arrive in the elevator lobby, there are views through the space to the outside. Playful elliptical forms on the lower half of glass doors at the entrance and on the conference room doors serve several purposes. “In a space with so much floor to ceiling glass, it was important to mark the glass is some way for safety reasons,” Wilson explains. “We also wanted to cover up the cluttered look of conference chair casters and the like.” The ellipses came out of the idea of creating organic imagery without being literal, like dolphins or butterflies. “The shapes are whatever you want them to be,” says Wilson. “Some people see petals, some see lily pads, and some see cells.” Ellipses made of agriboard are repeated in various shapes and sizes, and attached randomly to the exposed painted ceiling in the reception area.
Private interior offices have floor-to-ceiling glass walls, so every office and workstation has a view to the outside from a seated position. “The positive affect of natural light is well documented. It is very important to the overall well-being of people to sense the changes of the sun over the course of the day and even to be aware of the weather conditions,” Wilson says. “From an interior office, even though you are looking past an open workstation and through a perimeter office beyond, you still get that much needed connection to the outside.”
Among the challenges to the design team were the long, narrow proportions of the space, and extremely low ceiling heights (only 8½ feet slab to slab). In addition, the program required spatial efficiency and flexibility within a compact plan. Workspaces are standardized in three identical types: perimeter offices (120 square feet), open workstations (56 square feet), and interior offices (100 square feet). As various programs grow or contract, offices within the same type are interchangeable. Additionally, 120-square-foot “huddle rooms” are sized to become offices if need be.
The large conference room may be sub-divided into separate rooms with an acoustically rated operable partition. One side of the room has predominately clear glass doors, and the other side has mostly translucent doors for privacy. A series of full height glass panels pivot open to the reception area to allow free flow of people between the two spaces during large gatherings. The custom designed sectional conference table can be arranged in a variety of configurations. The modesty panels are removable and table legs fold flat for easy storage.
Every material incorporated into the project was scrutinized for its environmental qualities, and also had to meet the highest functional and aesthetic standards. The majority of materials are high in recycled content including: gypsum board 100%; rubber flooring 100%; seating fabric 100%; ceiling panels 74%; ceramic tile 55%; and carpet 25%. Zero VOC paints and zero or very low VOC adhesives were used throughout. Open workstations, office desks, and conference tables were custom designed from eco-friendly materials including FSC certified wood, wheatboard, and bio-composite board. Break room tables are made of a wood resin material that can be recycled back into itself. Two-thirds of the office seating was salvaged or reused. All file cabinets were salvaged or purchased used and refurbished. In many areas, including the perimeter offices, ceilings have been left exposed to the existing slab and painted, reducing the need for ceiling materials. Even the method of creating the elliptical forms on the glass doors was considered. As Wilson explains: “We wanted to avoid actually etching the glass because of the permanence and lack of future flexibility. We also wanted to avoid the use of any vinyl products, which most of the films are made of. While doing some online research, I actually discovered the acrylic film (non-vinyl) we ended up using. The film is applied on alternating sides of the glass that creates the ‘overlapped’ look.”
Energy efficient fluorescent lighting used throughout and occupancy sensors in all offices reduce energy consumption. Carbon dioxide sensors monitor air quality and special filters remove off-gassing from copy machines. Recycling stations are placed in multiple locations.
The office is located in the Kalorama area of the District, a high-density urban environment, with hotels, conference centers, restaurants, retail stores, a post office, movie theaters, galleries, nightlife, health club, and housing located within a one-block radius. Multiple bus lines stop in front of the building, and there’s an underground Metro Rail station within one-half mile. The building offers bicycle storage, and a shower facility is provided within tenant space.
The project was completed in
January 2002, and is under consideration to be one of the first pilot projects
for the new LEED Commercial Interiors
