Project Narrative
The Cambridge Public Library's renovation includes a double-skin curtainwall system, measuring 180 feet long, 35 feet high, and 3 feet deep with adjustable louvers. This system enhances transparency and regulates heat gain, loss, and glare. It achieves approximately 50% energy savings over standard curtainwalls and enhances comfort in reading spaces. The 3-foot airspace is seasonally adjustable, opening in summer to prevent heat entry and closing in winter for insulation.
