⚠ Key Exclusions & Notes
  • Savings depend on commissioning quality and proper system tuning.
  • Occupancy and daylight savings only apply where included in scope.
  • Demand and TOU adders only apply when the tariff structure supports them.
  • Refrigerant impact excluded unless project-specific data is entered.
  • Use benchmark ranges as reference only — results are not a guarantee.
