US Coast Guard

Project Overview

Pro-Tech Energy Solutions was hired to perform a multi-faceted design-build energy conservation project for the USCG base in Cape May, NJ. The project consisted of the replacement of two existing heat-only rooftop units with two new high efficiency rooftop units equipped with hot water heating, desiccant heat recovery, and DX cooling with remote condensing units. The project also included the removal and replacement of exposed ducting, the installation of sound attenuators, and the integration of the systems into the USCG’s campus-wide building management system.

Project Challenges

The equipment was located on the roof almost 200 feet from the nearest available crane rigging location. This required the use of a 500 ton crane to remove the old equipment and set the new units. The building space remained occupied allowing only minimal down time to transition from the old to the new equipment. In addition, the installation had to be coordinated with a new roof replacement and the installation of a new transformer and electrical service.
