TYLin provided engineering and project management services for the study and redesign of the heating and cooling system for the United States Postal Service (USPS) Process & Distribution Facility in Charleston, South Carolina.
The project for the 203,175-square-foot facility was split into multiple phases and part of a larger Indefinite Delivery Contract with the USPS.
In Phase One, TYLin prepared a study and Energy Efficiency Report for the heating system in the large mail sorting room. The room was originally illuminated by large, overhead high-intensity discharge lighting that provided heat for the space.
The study recommended installing new, more energy-efficient electric resistance heat coils in the workroom’s air handling units, enclosed mail platforms, and ancillary spaces between workroom and platforms.
In Phase Two, TYLin provided construction administration services for the installation of the new electric resistance heat coils and conducted onsite inspections during construction, pre-final inspection, and final inspection.
TYLin investigated the heating, ventilation, and air conditioning (HVAC) controls for the units in Phase Three. The team evaluated the feasibility of repair or upgrade instead of a total replacement.
In Phase Four, TYLin developed plans and specifications for the HVAC controls and systems upgrades.
- HVAC system work included the replacement of three air handles, upgrade of the HVAC controls, and replacement of three chillers or cooling towers with two new chillers or cooling towers.
- The measurement and verification portion of the work included 10- to-12-month utility load calculations, with completed energy form submitted during the 30% design phase.
