    1. Introduction to Data Centre Design

    2. Raised floor design issues Load bearing capacity Height Finish/décor Plan access ramps Plan air grill and damper location Seal all the system for air con efficiency and fire spread reduction Earth bond all the metalwork Good and suitable finish to original floor

    3. 600 and 610 mm floor tiles

    4. Minimum ceiling height: The minimum height in the computer room shall be 2.6 m (8.5 ft) from the finished floor to any obstruction such as sprinklers, lighting fixtures, or cameras. Cooling requirements or racks/cabinets taller than 2.13 m (7 ft) may dictate higher ceiling heights. A minimum of 460 mm (18 in) clearance shall be maintained from water sprinkler heads.

    5. TIA 942

    6. Raised floors

    7. Raised floors - loading

    8. Floor heights

    9. What height? 450 – 600 mm, IBM 450 min, 600 ideal, SUN 300 – 600 mm, BS EN 12825 300 mm min, TIA 569 Raised floor min height 460 mm, BICSI

    10. A deeper floor evens out the air pressure and distribution

    11. Where will the cables go? Under floor. Out of sight, out of mind Will interfere with air flow Under the ceiling Less aesthetically pleasing Easier to manage and change

    12. If cables must go underneath…..

    13. This kind of cabling negates the plenum zone effectiveness at air distribution

    15. Requirements The floor base must be clean, sealed and even The plenum zone created must be sealed, free of dust and with no cable or pipe work entrances that aren’t also sealed

    16. The reasons for pressure sealing the plenum area are; Chilled air conditioned air will be able to escape through poorly finished floor tiles and service penetrations, leading to; More electricity consumed to replace that air An inability to deliver the volume of chilled air required at the floor vents A variation in air pressure across the floor leading to an inability to deliver chilled air at the air vents Unsealed service penetrations (cables/pipes etc) into the plenum area are a fire risk and will allow the spread of fire and smoke into or out of the computer room (Building Regs, part B) Gaseous fire suppression systems rely on lowering the level of oxygen available to fires and depend upon a sealed area to work in to prevent oxygen from re-supplying the fire. BS ISO 14520 P1: 2000(E), Gaseous fire-extinguishing systems. Physical properties and system design. General requirements, requires a pressure test every twelve months Vermin  

    17. National Building Specification

    19. More K41

    20. The floor is an essential part of the cooling system “Poor airflow management takes 50% or more of the CRAC capacity” Pacific Gas and Electricity “60% of the cooled air in a typical data centre does not flow to where it is needed” (UpTime Institute) “70% of cooling air is wasted and bypasses back to return system” Mazzetti Associates

    21. Ramps

    22. Ramps: The Building Regs 2000 Part M. Access for disabled

    23. Build the Signal Reference Grid before fitting the floor tiles

    24. Grounding - earthing

    25. Beware zinc whiskers Zinc whiskers grow on metal stringers or off the bottom and sides of floor tiles that have a zinc electroplated-passivation coating on the sheet-metal pan. Specify hot-dipped galvanized (HDG) or electroplated zinc
