The GSA is renovating the 18 story federal building in Portland,
Oregon. Green features include a vertical green wall and reduced water
usage with low flow fixtures and recycled roof water.
"... part
of a $133 million renovation, the General Services Administration wants
to grow “vegetated fins” on the western facade of the Edith
Green-Wendell Wyatt Federal Building ... save energy year-round using
one of Mother Nature’s own tools."
" ... will use 60 to 65
percent less energy than comparable buildings. That translates to an
energy cost savings of $280,000 per year."
"Solar panels could also provide up to 15 percent of the building’s power needs. Energy use for lighting will be halved."
"...
building in question was already slated for an energy efficiency
upgrade, but funds from last year’s federal stimulus package stressed
projects that were environmentally friendly."
