A complete façade replacement while the building was 100% occupied the project required removing deteriorating stone cladding and installing a new energy-efficient unitized curtainwall. The renovation was a technical response to the enclosure's failure, an opportunity to improve the performance metrics of the building, and simultaneously upgrade its image. A short timeline for design, construction, and phasing was planned carefully between the contractor and tenant schedules in the occupied building.

​Our goal was to increase daylight and views, improving façade performance by decreasing air and water infiltration, minimizing envelope surface area and joints for initial cost savings, and long-term maintenance.
