Energy management for commercial real estate
See where your building wastes electricity
Vatt connects to the meters and controllers your building already has and finds waste: night-time base load, ventilation running in an empty building, demand peaks.

Ventilation ran overnight
Supply air unit AHU-1 missed its scheduled stop and ran all night in the empty building: +38 kW on top of the base load.
- What it costs
- ≈233 kWh, about $33 per night
- What to do
- Check the AHU-1 schedule in its controller and turn on schedule compliance monitoring.
08:00–08:35
Morning start-up peak
The chiller and two supply air units started at the same moment: a 356 kW peak, 11% above the usual daily maximum.
- What it costs
- A higher capacity charge, if your contract has one
- What to do
- Stagger equipment start-up by 10–15 minutes.
11:00–15:00
Heating and cooling at once
In the 4th-floor meeting rooms fan coils were cooling air that radiators were heating. The chiller worked for nothing: +22 kW.
- What it costs
- ≈84 kWh, about $12 over 4 hours
- What to do
- Separate the heating and cooling setpoints with a 2 °C gap.
What Vatt looks for
Waste shows in the shape of the curve
Vatt compares actual demand with the building schedule and its normal profile. When they diverge, you get an anomaly with an estimate in kilowatt-hours and dollars.
At night the building draws more than half of its daytime peak with nobody inside. Usually it is ventilation, car park lighting and equipment on standby.
Signal Night minimum as a share of the daytime peak
On Saturday and Sunday demand barely drops: climate and lighting schedules do not tell working days from days off.
Signal Weekends compared with weekdays
Air conditioning starts at 5 a.m. and runs until 11 p.m., while staff arrive by 9 and leave by 7.
Signal System operation against the occupancy schedule
Heating and cooling run in the same zone at the same time, so the equipment spends energy working against itself.
Signal Overlapping modes by zone
The reactive power ratio exceeds the limit in your contract, and the grid company may apply a penalty multiplier to distribution charges.
Signal tan φ per incomer, hourly values
Chillers, air handling units and pumps starting together create short peaks. If your contract bills for capacity, they raise the invoice.
Signal Hourly maxima and start-up times
How it works
From meter to decision
Five steps building data goes through before it becomes a report or a new schedule.
Connect
An on-site gateway polls meters and controllers over Modbus, M-Bus, BACnet or OPC UA. New meters are not required.
Meters at incomers and panels
Normalise
Readings from different devices are aligned to the same 5-minute intervals and mapped to building, floor and system. Communication gaps are flagged, not filled with guesses.
Floors and systems
Detect waste
Demand is compared with the schedule, the weather and the normal profile. Every anomaly comes with an estimate in kilowatt-hours and dollars.
Anomaly: ventilation at night
Automate
Climate and lighting schedules are edited in the platform. Writing to a controller is enabled per device; access is read-only by default.

Report
Once a month the owner and the facility manager receive a report: consumption by building, waste, measures taken and their effect.
