LEED / COMMISSIONING

Current Projects as of December 2020:

USPS Tampa PDC Chiller CX - The 310,250 SF Processing and Distribution Center is a single building which includes approximately 140,000 SF workroom floor, and three levels of administrative office areas.  The building is provided with chilled water by two central chiller plants, designated as the East and West chiller plant.  Each chiller plant consists of two water cooled chillers, two cooling towers, and chilled water pumps which are configured in a primary-secondary arrangement.  The two chiller plants are piped together so that chilled water can flow from one plant to the air handler of the second plant by manually opening or closing the valves located on the second level of the building.  An existing KMC Controls energy management system is utilized to control of all of the above systems.  The systems located in the West Chiller Plant were commissioned as a part of this project, and included two water cooled chillers, two cooling towers, two condenser water pumps, three primary loop chilled water pumps, two secondary loop chilled water pumps, and one exhaust fan.

 

SkyCenter One LEED Enhanced CX - The 288,949 SF Office Building is a 9-story building which includes a mechanical penthouse for the chiller plant.  The building is provided with chilled water by two water cooled screw chillers, and the chilled water system is configured for variable primary flow pumping.  The outside air for the building is provided by two energy recovery units with chilled water cooling coils to pre-condition the air delivered to each air handler serving a floor.  Each floor is conditioned by a single VAV central station air handler.  A Johnson Controls energy management system is utilized for the HVAC controls system.  This project is attempting LEED Certification under the v2009 Core and Shell rating system.  The systems commissioned as a part of this project included two water cooled chillers, two cooling towers, condenser water pumps, variable primary loop chilled water pumps,  exhaust fan, chilled water air handlers, VAV boxes, Energy Recovery Units, ductless air conditioning units, Building Automation System, lighting controls, a review of the Emergency Generator, domestic electric hot water heaters, plumbing hands free fixtures, and domestic water booster pump(s).
