The Green Grid & ASHRAE TC 9.9 Formulations:
• PUE = Ptotal / PIT (DCiE = 1 / PUE × 100%)
• Airflow: CFM = (1756 · PIT,kW) / ΔTrack,°C
• Volumetric Flow: Q = CFM × 1.699 [m³/h]
• Return Air Index: RAI = (Treturn − Tsupply) / (Track,out − Tsupply)
• PUE = Ptotal / PIT (DCiE = 1 / PUE × 100%)
• Airflow: CFM = (1756 · PIT,kW) / ΔTrack,°C
• Volumetric Flow: Q = CFM × 1.699 [m³/h]
• Return Air Index: RAI = (Treturn − Tsupply) / (Track,out − Tsupply)

📘 Calculation Methodology & ASHRAE TC 9.9 Standards
Power Usage Effectiveness (PUE)
The global standard benchmark metric defined by The Green Grid comparing total building facility power to IT mission-critical computing load:
PUE = Ptotal / PIT = 1 + (Poverhead / PIT)
Aisle Containment & Airflow Balance
Containment eliminates hot air recirculation and cold air bypass, allowing supply air temperatures to rise to $24^\circ\text{C}-27^\circ\text{C}$ to maximize chiller free cooling.
Key Engineering Assumptions
- Air density $\rho = 1.18\,\text{kg/m}^3$ at data hall operating elevations.
- Specific heat of air $c_p = 1.006\,\text{kJ/(kg·K)}$.
- ASHRAE TC 9.9 thermal envelope A1/A2 recommended operating ranges.
