Built for LEED Platinum certification, the Casey uses less than half the energy and has half the greenhouse gas emissions of a similar conventional building — proving that energy efficiency does not mean sacrificing livability. Owners in the high-rise building can open windows for fresh outdoor air; when windows are closed, heat recovery ventilators bring in fresh air, exhaust stale air and recapture waste heat. Air quality has been preserved by minimizing construction dust and pollutants, installing non-toxic finishes like wool carpet and using only safe cleaning products and processes.

Developer Gerding Edlen integrated aesthetics and performance with social and environmental awareness—for example, FSC-certified wood flooring looks handsome and comes from a well-managed forest. Building “commissioning” will verify that all building systems were installed and operate as intended, for an unusual level of quality control.
