Carr Hall Lobby


Carr Hall, originally constructed in the 1960’s, was renovated in summer of 2012 to create space for the growing Environmental Science department at Allegheny College. It was modeled to be 23 percent more energy efficient due to the renovation. Energy savings were achieved through building envelope improvements, heat recovery techniques and energy-efficient lighting.

Carr Hall achieved LEED Gold certification from the U.S. Green Building Council in 2013. The Gold certification recognizes the renovation’s exceptional use of sustainable materials including those with recycled content, rapidly renewable fibers, and a cradle to cradle manufacturing model; healthy indoor air quality; unique indoor landscaping, a living wall, and aquaponics systems; extensive daylighting thanks to solar tubes and skylights; and significant energy savings due to building envelope improvements, heat recovery techniques, energy efficient LED and T5 lighting, and CO2, motion and lumen sensors. Carr Hall is also Allegheny College’s showcase project for the White House’s Better Buildings Challenge.
