The proposal will emphasize energy efficiency in an effort to reduce heating and cooling costs.
Reconfigure system with main floor and caisson on separate zones allowing heated and cooled independent of each other.
Provide an alternate for the City to consider replacement of existing controls. Proposed controls to be Trane Control System, SCADA driven and accessible online.
