(1) Calculations - Use of professionally recognized, nationally used computerized
load calculations is encouraged. See pre -final submittal requirements.
NOTE: Copies of input and output data are required. Computer disks may also
(2) Outside Design Conditions - The following outside design temperatures shall
be utilized in the design of all new and rehabilitation type construction, excep t for critical
areas where specialized technical requirements demand exact humidity or temperature
control. For these areas, use 1% dry bulb temperature and 1% mean coincident wet bulb
temperature for summer and 99% dry bulb for winter as listed in NAVFAC P-89.
