Green interior design is a vast topic; designing healthy workplaces, using green materials, daylighting and good lighting controls, low-toxic finishes, low-emitting carpet, cabinetry and furniture from sustainably harvested wood, lower-water-using fixtures — the list goes on. The LEED for Commercial Interiors (LEED-CI) standard quantifies these measures in a point system. By early 2007, 34 projects had been certified under the LEED-CI version 2.0, including 4 Platinum-rated projects, and 59 under the LEED-CI version 1.0 (pilot) program, including 1 Platinum-rated project. Here we highlight the key elements of three of the Platinum projects and one Gold project.
InterfaceFLOR's showroom in Atlanta has shown its commitment to sustainability with the first Platinum-certified LEED-CI project. Opened in 2004 in an existing building, the project diverted 92% of construction waste from landfills, installed low-flow fixtures in restrooms, installed
energy-efficient lighting and lighting controls, reused 30% of furniture and fixtures, minimized VOCs used during construction and installed low-VOC carpets and furniture.77
In 2006 the architectural firm Cook+Fox relocated its offices in New York City and sought to redefine the firm and convey its vision for the future with a LEED-CI Platinum-rated interior remodel. Located in the i2,ooo-square-foot penthouse of a former department store in downtown Manhattan, the project has extensive daylighting from its 14-foot ceilings. A zoned lighting system uses energy-efficient metal-halide and fluorescent lighting, as well as high-quality ambient light with desktop task lighting. The existing air-handler, relatively new, was upgraded with a variable-frequency drive and additional filtration. A 3,6oo-square-foot green roof uses biophilia design principles to fight the urban heat-island effect and to provide a visual amenity for the office. Water consumption has been lowered by 40% through fixture choices. Green materials were used throughout, and the firm instituted an extensive green cleaning program. The entire staff s home energy usage, as well as the building's, has been offset through the purchase of green power credits.78
The Society for Neuroscience's new headquarters in Washington, DC, received a LEED-CI Gold rating in 2006, covering the improvements on
three floors of an 11-story, 84,ooo-square-foot building. The project reduced water use by 22%, and HVAC systems comply with increased energy-efficiency requirements. Daylight-responsive controls are used at perimeter windows. All electricity used in the space comes from green power sources (wind). Recycled materials make up 22% of the total materials cost, including 39% of the carpet, 40% of the resilient flooring, 50% of upholstered wall panels, 33% of gypsum board, 71% of ceiling tiles and 50% of office furniture. All wood comes from FSC-certified forests. Low-VOC materials were used throughout.79
In February of 2007 the US Green Building Council moved into its new headquarters, a 22,000-square-foot remodeled space that received a LEED-CI Platinum certification. Some of the features include: rapidly renewable bamboo flooring, reused granite countertops and non-toxic paint on the walls. Employees in the open workspace areas enjoy abundant natural daylight and operable windows, and 93% of the interior has a view of the outdoors. Office furniture from the previous space was reused, and the ceiling tiles are recyclable. All lighting products are engineered for high efficiency and lower energy use; individual task lights allow employees to control light within their work area. The new office uses 40% less water via low-flow plumbing fixtures, dual-flush toilets and water-free urinals.
