Computer Room Ceiling
Ceiling or suspended ceiling (optional) height must be at least 2.50 meters so that the
premises may be air-conditioned without creating draughts. Insufficient ceiling height may
adversely affect the air-conditioning system and make personnel uncomfortable.
The primary ceiling and wall drops located at suspended ceiling level must be coated with
dustproof paint or varnish.
The suspended ceiling must be made of a non-pulverulent material (metal slabs or plates). To
avoid slab disintegration and the generation of dust, it is strongly recommended not to use
“mineral” type components.
Suspended ceiling features must be compliant with the following specifications:
•
•
•
•
•
•
•
reduce the sound level in the room,
improve the appearance of the room,
allow light fittings to be flush-mounted,
conceal pipes, ducts or channels,
glass or rock wool contained in a dust-proof bag or cushion,
suspended ceiling height: > 2.50 m,
plenum space: > 20 cm.

Computer Room Environment
The Computer Room must also meet the environmental conditions set out below.
1.11.1.
Sound-Proofing
The sound level in the Computer Room may be relatively high due to room structure,
air-conditioning and hardware ventilation systems. The most effective means of attenuating
noise are to:
•
•
•
use dedicated rooms (Printing Room, Console Room, etc.),
install a suspended ceiling,
sound-proof walls and partitions.
1.11.2.
Protection from Sunlight
Large glass surfaces must be protected from sunlight. External protections only may be used
(coating, canvas curtains or shutter blinds).
Note
Venetian blinds may not be used inside the Computer Room.
