MIL-HDBK-1003/3
b)
Solar Heat Gain
EQUATION:
Q = A * (SC * SHGF)
where:
SC = shading coefficient, and
SHGF = solar heat gain factor (look up the SHGF in a
handbook (e.g., ASHRAE Handbook, Fundamentals) for each exposure
and type of glass).
5.3.2
Infiltration and Ventilation
a)
Sensible
EQUATION:
Qs = 1.10 * CFM * (To - Ti)
(5)
b)
Latent
EQUATION:
QL = 4840 * CFM * W
(6)
where:
W = change in humidity ratio (lb water/lb air).
c) Ventilation Rates. Refer to ASHRAE Standard 62 or
contact the EFD or EFA for ventilation requirements for spaces
not listed below:
Auditoriums, theaters
15 cfm/person
Barracks (sleeping rooms)
15 cfm/person
Bedroom

Toilet, bath (private)
35 cfm/room
Toilet (public)
50 cfm/water closet or urinal
The total corrected outdoor air requirement for central
systems supplying spaces with different ratios of
outdoor-air-to-supply-air is determined from the following:
EQUATION:
CFMot = Y * CFMst
