Data Center Floor Tile and Airflow Audit Checklist [FREE PDF]

Raised floor tile placement and airflow management are foundational to data center thermal efficiency, directly impacting Power Usage Effectiveness (PUE) and equipment reliability. ASHRAE TC 9.9 provides the primary industry guidance for maintaining proper supply and return air temperatures, while TIA-942-B and Uptime Institute standards define infrastructure requirements for cooling system resilience. This audit checklist helps facility engineers identify airflow bypass, hot aisle/cold aisle co

Raised Floor Physical Integrity

Inspect raised floor tiles, pedestals, and stringers for physical condition and proper installation.

  • Are all floor tiles properly seated, level, and free from cracks, warping, or damage?
  • Are all floor tile pedestals and stringers free from corrosion, loose connections, or missing hardware?
  • Are blank (solid) floor tiles installed in all non-perforated positions with no unauthorized cutouts?
  • Are floor tile load ratings adequate and documented for current rack weights in this zone?
  • Please upload a photo showing the current floor tile layout and condition in the audit zone?

Perforated Tile Placement and Configuration

Verify that perforated tiles are positioned correctly to direct supply air to equipment intakes.

  • Are perforated tiles installed only in cold aisle positions directly in front of equipment rack intakes?
  • Is the perforated tile percentage open area (porosity) matched to the cooling load of each rack row?
  • Are adjustable perforated tiles used in high-density zones and set to the appropriate opening position?
  • Are there any perforated tiles installed in hot aisle positions that must be replaced with solid tiles?
  • What is the measured airflow velocity at a representative cold aisle perforated tile (fpm)?
  • What is the measured plenum static pressure beneath the raised floor in this zone (inches w.g.)?

Hot Aisle / Cold Aisle Containment

Evaluate the effectiveness of aisle containment systems in preventing supply and return air mixing.

  • Are all cold aisle containment panels, doors, and blanking baffles installed and free from gaps or damage?
  • Are hot aisle containment returns fully sealed with no gaps at the ceiling, walls, or end panels?
  • Are all empty rack unit positions in cabinets within containment zones fitted with blanking panels?
  • Are cable cutouts and floor penetrations at rack bases sealed with appropriate brush strips or grommets?
  • Is there visible evidence of hot and cold air mixing (e.g., fogger test or airflow visualization) in the containment zone?

Temperature Measurement and ASHRAE Compliance

Record intake and exhaust temperatures across the audit zone and assess compliance with ASHRAE thermal envelopes.

  • What is the measured cold aisle supply air temperature at rack intake height (°F)?
  • What is the measured hot aisle return air temperature at the highest rack elevation (°F)?
  • Is the delta T (difference between supply and return air temperature) within the acceptable range of 20-30°F?
  • Are there any rack intake temperatures exceeding ASHRAE TC 9.9 Class A1 maximum of 80.6°F identified in this zone?
  • What is the current relative humidity measured at the cold aisle mid-height (%RH)?

CRAC/CRAH Unit Operation and Positioning

Assess cooling unit placement, operational status, and contribution to airflow distribution.

  • Are all CRAC/CRAH units in the zone operational and showing no fault or alarm conditions?
  • Are CRAC/CRAH units positioned to avoid short-circuiting supply air back to their own return intakes?
  • Are CRAC/CRAH supply air temperatures and fan speeds set to site baseline specifications?
  • What is the measured supply air temperature at the nearest CRAC/CRAH discharge (°F)?
  • Are condensate drain pans clean, properly sloped, and free from standing water or biological growth?

Under-Floor Plenum Condition

Inspect the raised floor plenum for obstructions, cable management, and contamination affecting airflow.

  • Is the raised floor plenum free from cable bundles, abandoned equipment, or debris obstructing airflow?
  • Are all under-floor cable penetrations through fire walls properly fire-stopped and sealed?
  • Is the plenum depth adequate and consistent throughout the audit zone (minimum 18 inches clear)?
  • Is the under-floor plenum free from signs of water intrusion, moisture, or condensation?
  • Please upload a photo of the under-floor plenum condition in a representative section of the audit zone?

Capacity Management and Documentation

Verify that airflow audit findings are documented for capacity planning and regulatory compliance evidence.

  • Is a current as-built floor tile layout map available and reconciled with the physical configuration inspected today?
  • Has a Computational Fluid Dynamics (CFD) airflow model been updated within the past 12 months for this zone?
  • Are current PUE (Power Usage Effectiveness) metrics being tracked and compared against the ASHRAE target baseline?
  • Have hotspots identified in previous audits been remediated and verified as resolved?
  • What corrective actions, tile repositioning requirements, or follow-up tasks were identified during this audit?
  • What is the overall audit risk rating for this zone based on findings?
