Off-Site Construction, Laboratory Penthouse


Project Overview:

EAS was contracted to design, construct off-site and supervise the installation of this penthouse system for the BMS Laboratory. Nominal 84,000 CFM, 100% outside air system. Overall dimensions of 45’L x 75’ W x 9’ 7” H which shipped in (12) sections. Penthouse system included unique, custom supply and exhaust air control box installation.

Project Highlights:

1. All of the reheat coil piping for the supply VAV boxes is located inside the penthouse. (This eliminates long runs of hot water piping throughout the building. Any potential future leaks are controlled and easily serviced in the penthouse)

2. All supply and exhaust control box service, shut-off, repair, calibration, monitoring and observation are performed in the penthouse, not over classified space, and without access to critical environments

3. Heat recovery coil system in place, pre-piped, with recirculation pumps installed, wired and piped off site at the EAS plant

4. Once the penthouse was installed, architectural siding was added to match that of the building
