MIL-HDBK-1027/4A
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.
4.2.6.4
Controls. DDC is the control system of choice for HVAC systems.
Consider life cycle cost, maintenance, and customer preference.
4.2.7
Plumbing. General guidance for plumbing design is provided in
DM-3.01. 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 trainer devices, to prevent damage to equipment in the event of leakage
or condensation.
4.2.7.1
Compressed Air.
Comply with the requirements of NAVFAC DM-3.5.
Maintenance Repair Shop.
Provide shop air.
4.2.7.2
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.
4.2.7.3
Waste Systems. Guidance is provided in DM-3.01.
Accommodate oil
separators and interceptors.
4.2.7.4
Emergency Eyewash/Shower. Locate for ready access from hazard
areas such as the hypobaric chamber mechanical room. Provide curtain and
testing apparatus.
4.2.8
Electrical. Typically, specific electrical requirements for
training facilities and/or training device(s) are contained in a Technical
Manual. Applicable NAVFAC military handbook 1004 series provides general
guidance on electrical engineering. Consult them in conjunction with the
current editions of NFPA 70 and ANSI C2.
a) Hydraulic Pump Rooms. Provide steel conduit with liquid type
fittings where electrical cables are located in the same trench with
hydraulic piping.
b) Classrooms. Locate 120 volt convenience outlets for use of
portable audiovisual equipment. Provide conduit stub-outs with pull wire in
ceiling space for future ceiling mounted audiovisual aids, such as projection
systems. Locate remote control and microphone outlets off-center on front
wall, convenient to the podium. Provide two-way communications from
classrooms to administrative area or security desk, if required by the user.
c) Corridors. A shock hazard exists from convenience outlets in
areas where floor buffers are used. Provide locking type outlets and metal
device covers mounted high above splash zones.
d) Visitor Control. Consider an intercom which includes capacity
to receive calls from rooms where medical emergencies are likely to occur.
