Baseline Management · Module 3
FY 2024–25 baseline — investment-grade
Framed as an ASHRAE Standard 211 Level 3 investment-grade energy audit. Adjusted-baseline regression uses IPMVP Option B (retrofit isolation, all parameters) with cross-checks under Option D (calibrated simulation). Statistical acceptance is enforced against ASHRAE Guideline 14.

Independent variables & fit
Independent variables: Outside-air temperature (°C, hourly) · Occupancy fraction (0–1, hourly)
| Variable | Coefficient | Units | p-value | Note |
|---|---|---|---|---|
| Intercept | 118.60 | kWh/hr | <0.001 | Base plant draw at 0 load reference. |
| OAT (°C) | 14.82 | kWh/hr per °C | <0.001 | Cooling load sensitivity to outside-air temperature. |
| Occupancy (frac) | 236.40 | kWh/hr per unit | <0.001 | Guest-driven internal gains + service loads. |
| OAT × Occupancy | 6.31 | interaction | 0.003 | Coupled sensitivity — hotter days with higher occupancy compound. |
