Formula and units
GPU-h = devices × days × scheduled hours/day. Productive-equivalent GPU-h = GPU-h × productive share. Facility kWh = GPU-h × (average GPU kW + host kW/GPU) × PUE. Energy-only cost = facility kWh × US$/kWh.
How to read the result
The model treats the entered average draw as applying during all scheduled hours. Productive share does not reduce that assumed draw. Off-schedule idle energy, embodied impacts, storage/network power beyond the host allocation and peak design are excluded. The result is an allocation, not a metered bill or performance forecast.
