This LEED Silver main public library includes the preservation of the historic library (27,200 s.f.) and a major new building (76,200 s.f.). The project features the first double-skin curtainwall of its type in the U.S. (180’ long, 35’ high, 3’ deep with adjustable louvers), allowing for complete transparency while protecting from excessive heat gain, heat loss, and glare. The facade saves energy (50 % reduction compared to conventional curtainwall) & maximizes comfort at the reading spaces. The 3’ airspace opens in summer to keep heat from entering the building & closes in the winter to create an insulating “thermal blanket.” The Associate Architect is Ann Beha Architects.
