Constructed from the bones of a 32,000-square-foot structure originally built in 1968, Kansas City’s LEED Gold Barney Building has become a showpiece—and literal home—for Karbank Real Estate, a longtime client of RMTA. The new Class A office space, completed in 2014, features a slew of green features, including composite bamboo benches, rain chains, and a thermally broken curtainwall system, and inside, moveable elements keep spaces flexible and primed for special events.

But the project’s most interesting move—in addition to adding a fourth story and cantilevered deck—is its reliance on two 65-kilowatt Capstone microturbine gas generators, which will allow the office building to be taken off the grid entirely. The carbon emissions avoided are equivalent to planting 96 acres of pine forest, according to RMTA.
