Hotel energy saving without investment: a checklist by department

Hotel energy saving without investment means changing when equipment runs, at what set point and who is responsible, not buying anything. This checklist assigns each action to the department that can start it tomorrow, and every line is checked on the hotel's daily meter sheet, not on a supplier's promise.

The electricity bill arrives, the general manager asks what can be done this week without a capital request, and the answer that comes back is "switch to LED". That is a purchase. Much of the waste a hotel can remove this week is not a purchase problem but a schedule problem. After reading this article you will have a department-by-department list where each line names the change, the owner and the number that proves it, starting with daily meter readings a hotel can act on.

What counts as hotel energy saving without investment?#

Anything that changes a time, a set point, a load size or a person's habit belongs on this list. Anything that needs a part, a controller or a contractor does not.

Draw the line once and write it at the top of the page: no purchase order, no contractor visit, no new software. This keeps the list honest and stops it turning into a wish list. Measure before you change anything: read the meter at the same time each day and record it next to the occupied room count, so a change has something to show up against.

Accept that some effects are invisible on a whole-hotel meter. For those lines, record the hours a pump ran or the temperature in a corridor instead of a consumption figure. Give every line one owner and one review date; a line with no name is a suggestion, not an action.

Be clear about what this list cannot do. It cannot fix a plant that is sized wrong, a control system that fights itself, or a building with no sub-metering. Those are investment decisions and belong on a separate page, alongside what to check before investing in room controls.

Apply one rule to anything a guest can feel: cut waste, not comfort. Set points in occupied rooms stay where the hotel's standard says they are.

Which rooms waste energy while nobody is in them?#

Empty rooms are usually the first place to look for a no-cost saving, because a room that is not sold needs no cooling, no heating and no light, and no guest notices the difference.

Room status is not the same as occupancy. A vacant clean room, an out-of-order room and a room held for a late arrival need different treatment, and housekeeping usually knows which is which before the front desk system does. Curtains and blinds matter in both seasons: in summer, closing them in unoccupied rooms on the sunny side cuts the heat load before the air conditioning has to remove it; in winter, opening them lets free heat in.

Lights are a habit, not a technology. The last person out of the room turns off every light, including bathroom, wardrobe and balcony, and the room attendant's own working lights go off at the end of the section. An open window with the air conditioning running is the clearest waste in the building: attendants report it, and the front desk decides whether anything is said to the guest.

Agree one unoccupied-room set point with the technical manager and print it on the section sheet, so it stops being a matter of opinion between shifts. Faults belong on the same sheet: a door that does not close, a dripping tap, a fridge that runs all night, a broken window seal. The repair is cheap, the waste it causes is continuous. Do not switch off the fridge or the router in a room that is sold, and do not treat a guest's comfort setting as a fault to be corrected.

How does a kitchen waste energy before the first guest arrives?#

A kitchen often wastes more in the hour before service than during it: extraction, ovens, grills and dishwashers are switched on at opening time and run at full power while the room is still empty.

Write a start-up schedule. List the time each piece of equipment is switched on and move it to the time it is actually needed. A grill heating at 06:30 for a 07:00 breakfast is fine; the same grill heating at 06:30 for a 12:00 lunch is not. Run extraction when cooking happens, not when the kitchen is merely staffed, and check whether the make-up air is heated or cooled, because an extraction fan can pull conditioned air straight out of the building.

Cold rooms need discipline rather than money: doors closed, night blinds down, strip curtains intact, condenser coils cleaned on a schedule. A dirty coil is a permanent extra load that nobody sees. Cooking habits count too: lids on pans, right-sized pans on right-sized rings, water boiled in the quantity needed rather than a full urn for four orders. In the dishwashing area, run full racks, match the program to the soil level, and scrape into a bin instead of pre-rinsing under a running tap.

In low season and split service, close a section of the kitchen rather than running all of it for a small cover count. Record what you changed and the time it was changed, so the effect can be read against the meter and not argued about from memory.

Does the laundry save more from full loads than from new machines?#

In the short term, yes: a washer or dryer uses nearly the same energy for a half load as for a full one, so the cheapest saving in the laundry is waiting for a full load and running fewer cycles.

Load to the machine's rated capacity, not above it. An overloaded dryer lengthens the cycle and creases the linen, which turns a saving into a re-wash. Match the program to the soil level: the longest and hottest program on lightly soiled linen is a choice, not a requirement. Clean dryer lint filters and heat exchanger fins every shift, because a blocked filter adds drying time to every single load.

Run the laundry in blocks rather than through the day, so machines, ironer and hot water are not kept ready for a single towel. Heat the ironer and the hot water when the first load is ready, not at the start of the shift. Ask why linen is being washed: because it is dirty, or because the trolley came back full. The second is a scheduling problem, not a laundry problem. Changing towel and linen change policy is a guest decision that belongs to management, not a technical fix for the laundry to make on its own.

When should lobby and outdoor lighting actually be on?#

Public area lighting should follow daylight, opening hours and cleaning hours, not the shift pattern. Much of the waste in public areas is light left on for an empty room or for daylight that is already there.

Timers drift and are rarely reset after a power cut or a seasonal clock change. Give one person the job of checking every timer against sunrise and sunset once a month. Split circuits so that "half the lobby" is a switch position rather than a rewiring job; where that is not possible, it is an investment item and goes on the other list. Separate cleaning light from guest light: the lights a cleaner needs at 05:00 are not the lights a guest needs at 20:00, and the difference belongs in the shift handover.

Exterior and facade lighting runs on a photocell or timer, goes off after the last arrival, and is checked after every storm. Signage and shop windows are on when they can be seen and off when the street is empty. Record the switch-off time on the daily sheet, otherwise nobody can tell whether the change happened.

Which plant room set points can change this week?#

Pump hours, spa hours, closed wings and space heating set points can usually change this week. Hot water temperature cannot, because it is set by the hotel's Legionella control plan.

Pool filtration and pump hours are set by the pool regulation and by the operator's own risk assessment. Ask the pool's responsible person before shortening anything, and record the hours in the pool log. Sauna, steam room and jacuzzi should run for the hours guests actually use them, published at the spa entrance, not from building opening to building closing.

Closed wings and floors should be taken out of service properly: heating, cooling, lighting and hot water circulation are all addressed, and the closure is recorded so housekeeping and the front desk work from the same list. For space heating and cooling set points in corridors, back-of-house and offices, agree one number per zone with the technical manager and write it down where the team can see it. In the boiler and plant room, check the time program against actual occupancy, and check that the plant is not heating water for a wing that is closed.

Before emptying a pool for maintenance, ask your local water and sewerage authority where the water may go. The rule is local, not national.

How do you keep the list alive after the first week?#

You keep it alive by giving the whole list one owner, one number and one fixed slot in the day, and by reviewing it in public rather than in a folder.

One owner: the technical manager or chief engineer holds the list and the number, and each department head owns their own lines. One number: the meter reading per occupied room, taken at the same time daily, is the only figure the meeting needs. Fifteen minutes: put the energy line on the daily operations meeting you already run, following a 15-minute daily operations meeting agenda, rather than creating a new one that will be cancelled in a busy week.

Review at two weeks: keep the lines that moved the number or that nobody noticed, and drop the ones that cost more attention than they save. Write each change down with a date, so a new department head inherits a list and not a habit. Expect one or two lines to fail. A failed line is information about the building, not a discipline problem.

What to do next#

Read the meter at the same time tomorrow, write the number where the heads of department can see it, and put a name against every line on this list before the week ends. The list works as a loop: one department changes a time or a set point, the sheet records the number, the morning meeting looks at it, and the hotel keeps or drops the line.
