Energy optimization for multi-zone HVAC — with measurable payback.
HVAC typically accounts for 40–60% of a commercial building's electricity bill. Most of that load is set by schedules and setpoints that have not been reviewed in years. AmbiAutomation surfaces the waste, tunes the levers, and locks in the savings — measured against a documented baseline.
Six levers, one supervisory platform.
Schedule discipline
Zones running outside of occupied hours are the first and largest source of waste. Centralized schedules with hard lockouts eliminate it.
Setpoint caps
Cap how cold a zone can be set during peak hours. A 1 °C tighter setpoint band typically saves 5–8% of HVAC energy.
Occupancy-aware modes
Where occupancy data is available, drop unoccupied zones to setback and recover ahead of arrival.
Runaway detection
Detect units operating outside normal envelope — drifted into permanent-on, stuck damper pulling air against itself, or a sensor reporting outside calibrated range.
Demand response
Pre-cool during off-peak, coast through peak tariffs. Where DR signals are available, respond automatically.
Reporting + tariffs
Energy by zone, by floor, by tenant. Export to your tariff engine. Pin savings against a baseline.
12–24 months for most multi-zone deployments.
Multi-zone office and commercial buildings typically recover the install cost in 12–24 months from energy savings alone, before counting reduced facility-management overhead or extended equipment life. Each engagement is accompanied by a written savings model with the site's actual operating profile, not a theoretical projection.
Measured, not assumed.
Two to four weeks of pre-install measurement — interval-meter data where available, otherwise zone-level run-hours and active-time data captured by the on-site server during a non-intrusive observation period. Post-install, the same metric on the same calendar period. Weather-normalised where it materially affects the comparison. No theoretical models. No assumed savings.

Common questions.
How much energy can HVAC automation actually save?
In practice, 10–25% off HVAC electricity load in typical multi-zone commercial buildings. Savings come from correcting schedules, tuning setpoints, staging chillers, and eliminating simultaneous heat/cool waste. Actual delivery is measured against a documented baseline.
How is the baseline measured?
The first two to four weeks after commissioning capture per-zone load, occupancy, and setpoint data. That period is the baseline. Optimisation levers are then applied one at a time so each intervention's contribution is attributable.
What levers drive the savings?
Occupancy-linked scheduling (unoccupied hours drop temperature bands), setpoint discipline (tight deadband, no simultaneous heat/cool), chiller staging, ventilation-linked economising, and outlier-zone alarming so a stuck damper doesn't burn energy for weeks.
How is the savings result verified?
Monthly savings reports compare current-period consumption to the baseline, normalised for weather (degree-days) and occupancy. Reports are exportable for third-party M&V and can be aligned with IPMVP if required.
