in MIL-HDBK-1190. Otherwise, less complex, constant volume
unitary or air handler systems with zone control should be used.
c) Consider the level and responsiveness of maintenance
available at the customer's activity when selecting the HVAC
system. Success of the HVAC system is dependent upon acceptance
of the system by the local staff responsible for routine
maintenance. The staff should be able to understand the
operating principles and control logic. Maintenance of the
system should not require skills and knowledge beyond their
capability. Ensure adequate space is provided for equipment
maintenance and removal.
d) Consider the types of systems currently installed
at an activity when making system selection for new facilities.
Seek to provide consistency in system types unless a simpler,
less maintenance intensive system can be used in the new
e) Specify training of activity personnel comparable
to the degree of system and controls complexity provided and
considering level of existing knowledge. In addition, provide
customer guidance relative to maintenance personnel (including
level of knowledge) or contract maintenance support required for
the HVAC system.
Referenced Criteria. The principal criteria references
used in this handbook in order of priority are:
b) NAVFAC design manuals and military handbooks.
(Whenever a design manual is revised, the design manual is
converted to a military handbook.)
c) American Society of Heating, Refrigerating and Air-
Conditioning Engineers, Inc. (ASHRAE) handbooks and standards.
If a particular subject is not specifically addressed in this
handbook, ASHRAE criteria apply. For criteria that is not
available in ASHRAE criteria, use the best available information
applicable to the design requirement, including State and local
codes as applicable.
Safety. Design systems to meet requirements of
National Fire Protection Association (NFPA) 90A, Standard for the
Installation of Air Conditioning and Ventilating Systems and NFPA
90B, Standard for the Installation of Warm Air Heating and Air
Conditioning Systems and Department of Labor, 29 CFR Part 1910,
Occupational Safety and Health Standards.
