Attachment J-1502000-05 HVAC and Refrigeration Systems.xlsx

This is an equipment asset inventory spreadsheet for HVAC and refrigeration systems at the Naval Research Laboratory (NRL) facility in Washington, DC. The document catalogues over 600 individual HVAC components across two building locations (NRL-1 and NRL-2), including air handling units, fan coils, chillers, compressors, pumps, heat exchangers, controls, and distribution systems. Equipment is systematically organized by asset number, location, system classification (using Uniformat divisions D30 for HVAC), capacity specifications, installation dates, and physical location within the facility. Key systems documented include central station air handling units ranging from 1,200 to 15,000 CFM, scroll and screw chillers with capacities from 10 to 150 tons, multiple circulating pumps with varying horsepower ratings, direct expansion condensers, fan coil units in cabinet-mounted and duct-mounted configurations, and building-wide piping and ductwork systems. Installation dates span from 1945 to 2021, with most equipment installed between 1994 and 2013. The spreadsheet serves as a comprehensive baseline asset registry essential for the planned eight-year Facility Support Services contract (N4008027R1001) beginning February 17, 2028, where the contractor will assume responsibility for facility management, maintenance, and integrated systems support at NRL.
