Pilot Data
What buildings actually saved.
Real numbers from pilot buildings — HVAC runtime reduction, energy cost delta, and occupancy-normalized comparisons.

Measurement
How we measure savings.
Baseline: 12 months of BMS interval data (HVAC kWh, AHU runtime, zone temperatures) from before Celaxis deployment. We normalize for heating and cooling degree-days and occupancy headcount. A milder summer or a lower headcount quarter doesn't count as our savings.
Comparison: HVAC kWh in Celaxis-controlled periods versus the same normalized baseline months. This is pilot data from fewer than 10 buildings — we say that clearly because the range will narrow as more buildings come online. We don't cite case studies we didn't run ourselves.
Pull 12 months of BMS interval data before deployment — HVAC kWh, runtime, zone temps.
Normalize baseline to degree-day and occupancy averages for the comparison period.
Measure HVAC kWh during Celaxis-controlled periods using the same normalization.
Delta = normalized baseline minus controlled period. Dollar savings at actual utility rate including demand charges.
Numbers
Pilot building results
HVAC Runtime Reduction
Average across pilot buildings. Measured as reduction in AHU operating hours per normalized degree-day versus 12-month pre-deployment baseline.
Lighting Energy Reduction
Buildings with automated lighting control via BMS integration. Daylight-linked dimming + pre-occupancy schedules combined.
Annual Savings per 100K sqft
Range reflects tariff structure. Buildings on time-of-use rates with steep 15-minute demand charges reach the high end. Flat-rate tariffs see the lower bound.
Peak Demand Reduction
Reduction in 15-minute peak demand interval, which drives the demand charge line item on most commercial utility bills.
Building Snapshot
Hartfield Tower, Portland OR
Monthly HVAC cost before: $38,400. After 6 months with Celaxis: $24,900. Monthly savings: $13,500 — of which $4,800 was demand charge reduction alone.
