The Wang Theatre was originally built in 1926, the plans for updating consisted of three phases. Phase 1 consisted of a chiller replacement, new generator installation and associated roofing work. Phase 2 consisted of chilled water plant upgrades and controls optimization. Phase 3 consisted of life safety work and lighting improvements. All of the work was carefully scheduled and planned according to the theater's ever-changing performance schedule. Two failing 250 ton air cooled chillers were replaced to ensure energy saving costs for the theater. Air side economizer controls were added to the existing 90,000 CFM air handling units, which allows the chiller plant to shut down during the late fall, winter and early spring periods. New emergency egress lighting and aisle way lighting were also added.
