MIL-HDBK-1027/4A
Provide non-obtrusive observation glass panels where desired by the
user in classrooms, laboratories and other non-private trainee occupied
areas. Glazed openings that are subject to accidental human impact due to
location, such as sidelights that extend to the floor, should comply with 16
CFR Part 1201, Safety Standard for Architectural Glazing Materials, issued by
the U.S. Consumer Product Safety Commission.
3.2.2.8
Doors and Hardware. Exterior wall overhead doors can be a critical
source of extreme heat gain/loss and air and moisture infiltration into lab/
classroom settings where temperature and humidity conditions must be
maintained. Overhead coiling doors to the exterior are not acceptable for
environmentally conditioned spaces. Provide weathersealed insulated vertical
lift or sectional doors or insulated removable panels with lifting eyes.
Insulated panels must be easily removable by facility personnel. Provide
adequately sized interior corridor doors for classrooms with oversized
equipment, where possible, in lieu of exterior openings into each classroom,
to minimize exposure to exterior elements. Size all doors to accommodate the
path of oversized equipment from loading areas to destination and between
rooms. Provide inactive leafs and removable transoms where equipment moves
are infrequent. Allow for maneuverability in tight corridors.
a) Classrooms or other areas where classified information is used
should not have doors with viewing windows.
b) Provide four hinges where required on heavy use doors. Avoid
panic hardware except where specifically required by criteria, since the Navy
does not classify training facilities as schools.
3.2.2.9
Natural Lighting. Natural light is encouraged, as it contributes
significantly to the energy efficiency of the building and communicates a
feeling of well-being and openness. Natural light can be used in conjunction
with high efficiency artificial lighting, featuring photosensitive controls
for maintaining lighting levels automatically. Skylights are not permitted,
due to excessive solar heat gain and leak potential. Classroom wing
corridors and other interior occupied spaces may incorporate monitors with
conventional roofing and vertical windows. High bay spaces may incorporate
clerestory windows in cases where natural lighting is desired without any
distracting or unsightly views.
3.2.2.10 Building Thermal Insulation and Vapor Retarders. Locate vapor
retarders with care in view of the thermal differentials associated with
training buildings. Do not use vinyl wall covering and impervious paint on
the interior surface of exterior walls in humid areas, unless calculations
show that condensation will not occur within the wall.
Special purpose rooms such as laboratories and computer rooms
normally require stringent air conditioning requirements. Provide adequate
insulation and vapor transmission barriers to minimize the loads on the
mechanical system. Ceiling decks of spaces below supercooled computer rooms
and perimeter walls are apt to collect condensate if not properly insulated.
3.2.2.11 Handicapped Design. Provide barrier-free access to civilian work
spaces and other spaces intended for public access. Design facilities to
locate handicapped access spaces on first floor only, unless the size of the
facility's administrative and other accessible areas requires a second floor.
