59. “We see a retrofitted and expanded Aiken
Center that provides needed space but has a
smaller ecological footprint, uses
natural lighting, and has pure air and
ecological elements, including water and
plants, in its corridors. The Aiken Center
should be the first institutional building at
UVM that beautifully celebrates
life within. We envision a year-round
greenhouse and native landscaping, with state-
of-the-art energy and water conservation and air
circulation. The Aiken Center will be a place
like no other and represent a harbinger
for our future.”
