Assumptions & formulas — G4-ENERGY-ASSUMPTIONS v1.0 (2026-10)
- Lighting/HVAC kWh = rooms × occupancy × kW/room × load factor × h/day × days (occupancy applied once)
- Auxiliary kWh = rooms × kW/room × load factor × h/day × days (not occupancy-dependent)
- Load factor: lighting 0.55, HVAC 0.45, aux 0.6 · Season HVAC: ANNUAL_MIX 1, HOT 1.15, MILD 0.85
- CONSERVATIVE: L 25% · HVAC 18% · aux 8% | EXPECTED: L 35% · HVAC 27% · aux 12% | OPTIMISTIC: L 45% · HVAC 35% · aux 18%
- Monthly figures distribute HVAC by the seasonal profile and sum exactly to the annual total. Payback = cost ÷ savings, not shown at zero. Emissions only with an entered factor.
