MIL-HDBK-1027/4A
3.2.6.3
Zoning, System Selection and Part Load Performance. Occupancy of
classroom areas varies drastically with respect to training schedule.
Consider each classroom/training area as a separate temperature and humidity
control zone. Provide individual temperature controls for each classroom.
Size terminal equipment to accommodate minimum as well as maximum loads.
Multiple air handling units (allowing staged turn-down of system capacity as
sensible load falls) should be considered. Terminal reheat is permitted to
meet part-load humidity performance requirements; in electronic equipment
spaces, the amount of reheat available should be approximately equal to the
sensible electronic load within the space.
3.2.6.4 Controls. DDC is the control system of choice for HVAC systems.
Consider life cycle cost, maintenance requirements, and customer preference.
3.2.7
Plumbing. General guidance for plumbing design is provided in
DM-3.01, Plumbing Systems. Coordinate plumbing with structural design to
avoid conflicts between underground pipes, trenches and footings. Provide
shut-off valves to isolate systems when doing maintenance, so that entire
facility is not affected by an outage. Do not locate roof drains and roof
drainage piping over computer spaces and trainer devices to prevent damage to
equipment in case of leakage or condensation.
3.2.7.1
Mechanical Pump Rooms. Floor drains subject to oil spills must
drain to an oil separator. Provide flexible couplings between pumps and
piping systems for vibration and sound control.
3.2.7.2
Compressed Air. Comply with the requirements of NAVFAC DM-3.5,
Compressed Air and Vacuum Systems.
3.2.7.3
Electric Water Coolers. Splash resistant basins are recommended to
prevent slippage on the floor and shock hazard. Handicapped models should be
recessed as required to minimize obstruction to passage.
3.2.7.4
Waste Systems. Guidance is provided in DM-3.01, Plumbing Systems.
Accommodate oil separators and interceptors as well as special drain
requirements for HVAC, chillers, and trainer equipment.
3.2.7.5
Emergency Eyewash/Shower. Locate for ready access from hazard
areas. Slope floor to drain beneath shower head. Provide curtain and
testing apparatus.
3.2.8
Electrical. Typically, specific electrical requirements for
training facilities and/or training device(s) are contained in a TFR or
Technical Manual. Applicable NAVFAC design manuals and military handbooks
provide general guidance on electrical engineering. Consult them in
conjunction with the current editions of NFPA 70, National Electric Code, and
ANSI C2, National Electric Safety Code.
Provide two-way communications from classrooms to administrative
area or security desk, if required by the user. Provide centralized 400 Hz
solid state invertor and 24 VDC, both with backup for service to appropriate
trainers without integral units.
