concepts are well coordinated between the various design disciplines,
in particular, between the mechanical/electrical concepts and the
architectural features of the building.
In order to achieve success in meeting the energy budget, architects,
mechanical engineers and electrical engineers are advised that they
must actively interface and participate in the building design
formulation at the conceptual design stage. It is not intended that
additional energy reduction be the sole responsibility of the
mechanical/electrical design through the use of exotic or
unnecessarily complex systems. Conversely, appropriate architectural
features should not be sacrificed to make up for mediocre
mechanical/electrical design in achieving the energy budget. Success
will require the earliest consideration and cooperation of all design
For projects other than those involving new facilities, the A/E shall
include those features which will reduce energy consumption to the
maximum extent feasible and economically justifiable as required by
the Appendix "A".
Load calculations for HVAC design shall be based upon the weather
data provided in the Appendix "A".
Air Handling Fire Protection Requirements
a) Design Requirements: Air handling, ventilation, and exhaust
systems shall meet the design requirements of the following, except
as modified herein:
NFPA No. 90A, "Air-Conditioning and Ventilating
NFPA No. 90B, "Warm Air Heating and Air-Conditioning
NFPA No. 91, "Blower and Exhaust Systems".
NFPA No. 96, "Commercial Cooking Equipment, Vapor
NFPA No. 101, "Life Safety Code".
b) Corridors: Corridors shall not be used in lieu of ducts for
air handling (either supply or return) in hospitals, dispensaries,
bachelor quarters, temporary lodging facilities, schools, places of
assembly, and in windowless buildings. Use of corridors for air
plenums shall be avoided in other occupancies (see MIL-HDBK 1008,
"Fire Protection for Facilities Engineering, Design and
c) Plenums: Ceiling plenums waste energy, pick up particulate
(dust and fiberglass) from insulated spaces and introduce serious
smoke and fire spread potential. Ceiling plenums should not be used
as an integral part of an air handling system; they may be used only
