Perkins+Will’s new Atlanta office is the current highest-scoring LEED Platinum project in North America under the 2009 version of LEED -NC. The building, originally constructed in 1985, minimizes energy use by 58% and potable water use by 78%. Exterior renovations included energy efficient exterior glazing, alterations to the front facade, a new 5th floor terrace for meetings and social events, and a garden for employees.
The structure uses an active, dynamic exterior sunshade on the terrace level to control afternoon sunlight and heat gain. For climate control, the building uses raised flooring and a radiant heating and cooling system, microturbines, and an absorption chiller. The project reused, repurposed, recycled or otherwise diverted 80% (630 tons) of material from the building.
