Malaysian hotels cut electricity costs mainly by optimising chillers and AHUs, setting back air-conditioning in unoccupied rooms and function spaces, switching to heat-pump hot water, scheduling kitchen and laundry equipment, and adding solar. Infinergi monitors each system with Eniscope IoT sub-metering and provides monthly ESG reports for owners and corporate clients.
Where hotels use and waste energy
Hotels run around the clock, so waste adds up quickly. Air-conditioning is usually the largest load, followed by hot water, kitchens, laundry, lighting, lifts and pumps.
| Area | Common waste | Fix |
|---|---|---|
| Chillers & AHUs | Poor sequencing, fixed set-points, AHUs running for empty spaces | Chiller optimisation, schedules, VSDs |
| Guest rooms | AC running in unsold or unoccupied rooms | Occupancy-based set-back, room-status integration |
| Ballrooms & meeting rooms | Pre-cooling hours before events | Event-based scheduling |
| Hot water | Electric resistance heating | Heat-pump water heaters |
| Kitchens & laundry | Equipment switched on long before use | Equipment schedules and monitoring |
| Lighting | Back-of-house and car parks lit 24/7 | LED with sensors and timers |
Our approach for hotels
- Free energy audit of 12 months of TNB bills against occupancy.
- Eniscope monitoring on chillers, AHUs, kitchens, laundry and key floors, installed with no guest disruption.
- Quick wins in scheduling and set-points, then upgrades ranked by payback.
- Solar and storage on roofs and car parks, with backup for critical loads.
- Monthly ESG reports for owners, operators and corporate clients.
Why it pays
Because hotels have 24/7 loads, every kWh saved repeats every hour of the year. That makes hotels ideal for the full solution: efficiency, solar and storage, with zero CAPEX financing available so savings start without capital.
