Comparing kitchen energy use is difficult when one kitchen serves breakfast only and another runs several meal periods. Total consumption reflects opening hours, menu, equipment and production volume, so a simple month-to-month bill comparison can mislead. Start by defining what each kitchen does, then match energy use to the activity the team is trying to improve. For the wider hotel context, see asset optimisation e hotel owners e Feathers Hospitality approach.
These practices work best when information, ownership and verification are part of the routine rather than dependent on one person’s memory. {“A abordagem da Feathers Hospitality” if loc==”pt” else “The Feathers Hospitality approach”} liga orientação e execução.
Key points
- Compare kitchens with service hours and meal volume in view.
- Separate systems where reliable readings exist.
- Keep ventilation and food safety as constraints.
What information makes two kitchens comparable?
Record service hours, meals served, menu profile, preparation method, refrigeration load, equipment inventory and area. Note whether the meter includes extraction, dishwashing or nearby spaces. A kitchen operating longer will normally have a different load profile; the comparison needs to make that difference visible.
Where possible, collect submeter or equipment-level readings for the systems under review. If only a building-wide bill exists, do not claim a precise kitchen figure. Document the allocation method and how confident the estimate is.
Which measures should be compared?
Use total kilowatt-hours alongside a service-based denominator such as meals served or hours open. Consider separating refrigeration from cooking and dishwashing if the meters permit it. Keep the same definitions across properties and explain any excluded service.
A lower energy-per-meal figure does not automatically mean a better kitchen if menus, quality, production volume or opening periods differ. Compare operating context and service outcomes. ENERGY STAR’s restaurant efficiency resources provide US guidance on profiling restaurant energy, not a universal hotel benchmark.
How do opening hours affect the result?
Map start-up, warm-up, service, cleaning and shutdown periods. Equipment may draw energy before the first meal and remain on after the last. Compare these intervals before attributing a difference to staff behaviour or equipment condition.
Use a representative period that includes normal trading and note events or closures. If the hotel changes breakfast or dinner hours, mark the date and allow the new routine to stabilise before assessing its effect.
Which equipment needs a closer look?
Refrigeration, extraction, ovens, dishwashers, hot holding and water heating can contribute differently according to use. Check condition, set points, maintenance, door seals and run schedules with qualified staff. A visible appliance label does not tell the whole system’s consumption.
The US Department of Energy’s commercial kitchen resources can help frame equipment questions; confirm local technical and safety requirements in Portugal. Do not disable ventilation or change food-safety temperatures to pursue an energy target.
How can a change be tested fairly?
Choose one intervention with a clear mechanism, such as a revised shutdown checklist or a maintenance repair. Record the baseline, dates, operating hours, meal volume and any other changes. Compare similar days or weeks and keep the quality and safety checks constant.
If several measures begin together, the result may show an overall change without identifying which measure mattered. That may be acceptable for an operational review, but say so. Use an estimate range where meters or meal counts are incomplete.
How should results reach the owner and kitchen team?
Report the change in energy, the denominator, data limitations and any effect on service or maintenance. Show absolute use as well as normalised use. A short chart with clear units is easier to act on than a ranking with no explanation.
Ask kitchen staff whether the change is practical and whether it created new work or service delays. Review after a representative period and update the operating procedure if the result holds. The goal is a dependable kitchen service with better-informed resource decisions, not a metric detached from the guest experience.
Frequently asked questions
How can kitchens with different menus be compared?
Record meal volume and type, equipment and service hours. If the context differs, state the limitation and avoid presenting a simple ranking.
Can equipment be switched off to reduce energy use?
Only where food safety, ventilation, storage conditions and manufacturer instructions allow it. Have technical and kitchen leads review any change.
