Hotel energy
monitoring system
Sub-metering for the zones that drive a hotel bill: chillers, kitchens, laundry, guest floors and public areas, centralised with interval demand. The same data shows the engineering team when plant stops and how fast it was brought back.
THE PROBLEM
Hotels run around the clock, and so does the waste
A hotel never closes, which means the chiller plant, kitchen extract, laundry and corridor lighting are all candidates for running when they do not need to. The general manager sees one utility bill and an occupancy figure, and has no way to tell whether a bad month came from the weather, a banquet season or a chiller that short-cycled for three weeks.
For hotel engineering, energy and uptime are the same conversation. When a chiller trips after a power failure, the first sign is often a guest complaint about a warm room. How quickly maintenance responds is something chief engineers are measured on, but rarely have data for.
Hotels also face peak demand charges. A laundry and a kitchen starting together with the chillers at full load can set the demand figure for the whole month.
HOW WE SET IT UP
Zone sub-meters, one view for engineering
Meter the major energy zones
We submeter the chiller plant, AHUs, kitchens, laundry, guest floor risers, pools and public areas. That covers the large loads with a sensible number of points and gives the GM a split that makes sense.
Interval demand alongside kWh
Interval power readings show which loads coincide at the monthly peak, so the team can stagger laundry and kitchen starts and see the effect on the demand figure.
Run status and downtime
Power draw on chillers and AC units shows whether they are running. RIOD Live records every stop, alerts the duty engineer by call or WhatsApp, and logs how long the restart took.
Plant controllers through Modbus
Chiller and BMS controllers often expose energy, status and alarms over Modbus. Our gateway reads them alongside the sub-meters, so the plant room is on one screen.
FROM THE FIELD
Where we have done this
Taj Hotels: chillers and air conditioning
We monitored power and run status on chillers and AC units so the engineering team could see downtime as it happened and track how quickly maintenance responded, instead of learning about a failure from a guest.

FAQ
Questions buyers ask us
What should a hotel energy monitoring system measure?
At minimum the chiller plant, AHUs, kitchens, laundry and guest floor risers, plus interval demand at the incomer. Those loads explain most of a hotel bill and most of its peak demand charge. Run status on chillers and AC units adds the uptime picture engineering needs.
How does energy monitoring help hotel engineering teams?
Energy monitoring shows hotel engineers when plant stops and how long it takes to restart, which is how we reported chiller and AC downtime for Taj Hotels. Alerts reach the duty engineer directly, so a tripped chiller is handled before guests notice.
Can a hotel bill serviced apartments or retail tenants from this data?
The data supports internal allocation straight away. For direct billing to residents or tenants, many jurisdictions require approved meters, so we plan the meter selection and approvals for those circuits with you.
Does it work with our existing BMS?
Yes. Our Modbus gateway can read BMS and chiller controllers, and RIOD Live can pass data back to the BMS or another system through an API.
