About this file

This is a mechanical schedules and control drawing (Sheet M-601) for a Building 1083 HVAC replacement project at Fort Story, Virginia Beach, conducted by Naval Facilities Engineering Systems Command (NAVFAC). The drawing, dated August 12, 2026, documents the redesign of discontinued equipment and missing information for the male head mechanical systems.

The document contains three primary equipment schedules: an Air Handling Unit (AHU-2) Schedule specifying a 990 CFM horizontal unit with 0.9-inch ESP, 1.5-inch total static, and 21,976 BTU sensible capacity; an Air Cooled Condensing Unit (ACUS-2) Schedule rated at 32.2 tons with R-454B refrigerant and 4-ton compressor capacity; and an Energy Recovery Unit (ERV-1) Schedule featuring a MECL MEZZ unit with 990 CFM airflow, rated for 82.6 BTU/lb sensible heat and 94% winter total efficiency. The document also includes a DDC (Direct Digital Control) input/output point summary table for a BACnet DDC panel, detailing control functions for the Energy Recovery Unit and Air Handling Unit including supply fan status, exhaust fan operation, air temperature sensors, damper positions, reversing valve status, and wall-mounted thermostat inputs. Electrical specifications, dimensions, and performance data are provided for each equipment type, with notes addressing single-point power connections, jacket interface requirements, and duct-mounted temperature sensors.
