Energy Conservation.
Design climate controlled facilities for energy efficiency. Consider isolated
ventilation of air conditioning systems for equipment with high heat loads or that
require more critical temperature or humidity control than would otherwise be
required for the remainder of the occupancy.
3-4.2
Equipment Selection.
Select adequately sized air conditioning equipment for personnel within these
areas. Computer rooms and electrical equipment rooms produce predominantly
sensible heat and require specially designed units. Ensure mechanical systems
do not interfere with electronic equipment or radiated signals.

electronic equipment. Provide controls to discontinue electric power to electronic
equipment upon water flow. Provide manual disconnect of electric power to air
traffic control equipment. Provide separation from other areas with fire-rated
partitions. Provide smoke detection, at ceilings and in sub-floor areas, connected
