Return
Airow Path
Does not require any
special provisioning
for the return of hot
exhaust air.
Requires either a
high ceiling with tall
chimneys or a drop
ceiling for return
airow path.
Similar to HA/CA,
does not require any
special provisioning
for the return of hot
exhaust air.
Requires special
provisioning for
the return of hot
exhaust air, with
the exception of an
application with row
level cooling
Water Cooled
vs. Refrigeration
Based Cooling
System
Compatible with
refrigeration and
chilled water based
systems because of
the low return
air temperatures.
Refrigeration based systems may not be compatible with very high
return air temperatures that may be produced.
Economizers
Compatible Increased hours
of economizer
utilization due
to high return
air temperatures.
Increased hours
of economizer
utilization due
to high return
air temperatures.
Increased hours
of economizer
utilization due

Cooling
System Failure
Tolerance
Hot aisle air will
be quickly drawn
to the cold aisle.
The average room
temperature factors
into the time to
critical alarms in
IT equipment.
Provides large mass
of cold air in case
of cooling system
airow failure.
Provides relatively
small thermal
mass in case of
cooling system
airow failure.

Room Height
Requires sufcient
height for raised
oor or overhead
supply ducting.
Requires high ceiling
for chimney and
allowance for return
plenum or hot
air stratication.
Requires sufcient
height for raised
oor or overhead
supply ducting.
Requires sufcient
height for ceiling
return plenum or
return ducting.
Comfort
The hot aisle is
relatively warm due
to mixing of cold and
hot air.
The entire room is
within a few degrees
of the supply
air temperature
(assuming VED on
all cabinets).
All areas outside
the cold aisle are
typically at a very
high temperature,
which may not be
an acceptable
working condition.
The entire room is
within a few degrees
of the supply
air temperature.
However, hot
aisle temperatures
may not be
acceptable for
working conditions.
Retrotting/
Browneld
Minimal challenges,
but limited
thermal density.
May be challenging
to t VED into
existing overhead
pathways (power,
structured cable,
etc.). Addition of drop
ceiling may
be required.
Can be built on
existing raised
oors with
minimal changes.
In most cases, it
is difcult to install
HAC in Browneld
applications, where
containment
systems are
an afterthought.
Fire
Suppression
Depending on
local codes, fewer
sprinkler heads may
be needed than for
VEDs or CACs.
Depending on local
codes, sprinkler
heads may be
needed in both the
hot and cold aisles.
Depending on
local codes, both re
detection devices
and sprinkler
heads might need
to penetrate each
containment system.
Depending on local
codes, sprinkler
heads may be
needed in both the
hot and cold aisles.
Lighting
Regular room
lighting system
is sufcient.
Chimneys will
prevent light from
traveling between
aisles. Lighting
xtures are likely
needed in both the
hot and cold aisles.
Containment
solutions may block
light provided by
overhead xtures.
Transparent roof
sections or internal
light xtures may be
required. Lighting
xtures are likely
needed over
each aisle.
