- As part of a $133 million renovation, the General Services Administration is planning to cultivate “vegetated fins” that will grow more than 200 feet high on the western facade of the main federal building here, a vertical garden that changes with the seasons and nurtures plants that yield energy savings.
- The G.S.A. says the building will use 60 percent to 65 percent less energy than comparable buildings and estimates a savings of $280,000 annually in energy costs. Solar panels could provide up to 15 percent of the building’s power needs. The use of rainwater and low-flow plumbing fixtures will reduce potable water consumption by 68 percent. And energy for lighting will be halved.
