Existing Distribution
Direct Replacement: Motor Loads = 2867.9 ARemoving Chillers: Motor Loads = 1341.9 A
-reduces size of incoming feeder bus
ELECTRICAL DEPTH
LIGHTING: Illuminated spaces to satisfy IESNA standards and ASHRAE power requirements
DAYLIGHTING: Reduced annual energy consumption by over 50% with integrated photosensor system
ACOUSTICS: Validated improvements with alternative flooring; not critical to implement
LED STUDY: Alternative general illumination system for labs insufficient
ELECTRICAL: MCC designed for mechanical penthouse is not practical
