4-1 GENERAL
4-1.1
CONCEPT:
Any building can be conceptualized as composed of a
g r o u p of subsystems, e a c h of which performs a function.
The design of
t h e s e subsys t e m s is th e m a j o r d e t e r m i n a n t of t h e c o s t a n d per f o r m a n c e of
the building.
The subsystems are, to some extent, interrelated and may
s h a r e some functions.
For example, t h e e x t e r i o r w a l l o r i n t e r i o r
partitions may perform a structural function. Thus, subsystems cannot be
e v a l u a t e d and chosen completely independently of one another. By
f o c u s i n g a t t e n t i o n , d u r i n g the early stages of design, on subsystems
r a t h e r than the buiIding as a whole, issues and alternatives are clarified,
a n d major design decisions can be made on an orderly and systematic basis.
4-1.2 SUBSYSTEM ALTERNATIVES: This section provides information on
subsystem alternatives that are appropriate to the Army club faciIity.
Subsystems are reviewed on a generic basis,
unrelated to specific building
d e s i g n or geographic location.
The information given wiII serve as a use-
f u l check list and guide for subsystem choice while the general
configuration of the building is developed.
The following subsystems are
reviewed:
Structure
Heating, ventilating,
and
cooling
Envelope
Interior partitions
Ceiling
Lighting
4-1.3 SUBSYSTEM COST:
F o r e a c h s u b s y s t e m , e x c e p t s t r u c t u r e , a cost
i n d e x is provided that shows the costs of subsystem types relative to one
a n o t h e r , within the same subsystem group.
The cost index is not
transferable from one subsystem to another.
Structural costs vary
significantly from one location to another and, in addition, the structure
m a y share roles with other subsystems such as exterior walIs or interior
partitions.
For this reason no comparative cost index is given for
structure.
The design of facilities constructed under
4-1.4 LIFE CYCLE COST:
M i l i t a r y Construction Programs must consider the potential economic
i m p a c t of suitable alternate subsystems and components over the life
This will include alternate considerations in
cycle of the facility.
such selection areas as structural systems, story heights, exterior
and interior finishes, interior utiIity systems, and power supply
