Johns Hopkins University | Applied Physics Laboratory Thermoelectric Laboratory

The APL Thermoelectric Laboratory Renovation was a fast-track project involving extensive mechanical and electrical systems modifications. The mechanical portion of this project included plumbing, new HVAC integration, and select plumbing and HVAC demolition—including VAV duct work, flex duct and thermostat removal. The existing condensing unit and abandoned split system was removed and replaced with new VAVDF units, a complete automatic control system, and compressed air system equipment and piping. The Lewis team provided new water service to the existing hoods, installed insulated domestic hot and cold water piping and valves, made modifications to the existing under slab sanitary piping, and added a new pressure independence module and pressure booster pump with the associated accessories. Within the laboratory the team also provided a new emergency shower station and new vacuum system equipment. The electrical work—including select demolition, disconnection and relocation of electrical systems—was also an integral portion of this laboratory renovation. Included in the new electrical services for the laboratory renovation were new receptacles—both drop cord and plug receptacles—new electrical panels and conduit boxes, and new lighting throughout the space. Select circuit breakers were removed and replaced and new equipment connections were provided. Fire suppression services provided by the Lewis team included modifications to the existing fire alarm system, firestopping of all penetrations, and the relocation of smoke detectors and other fire alarm devices.
