How leisure centres can cut energy spend without slowing sessions

When the pool is full and the courts are booked, you feel the energy meter spin. Then there are the quiet hours when plant hums away for almost no one.

The quickest way to trim costs without hurting service is simple: make your energy plan follow your programme, not the other way round.

Start with your “run of show”

Look at a typical week. Where are the reliable peaks and the dead spots?

• Early swim schools and evening five-a-side
• Mid-morning lull after the commuter gym rush
• Club nights and weekend galas

From here, set three operating “scenes” in the building management system: quiet, standard and event. Pre-heat and pre-ventilate only to what the next scene needs. If your system won’t do scenes, a simple scheduler with clear set points still works.

Procurement that matches your pattern

Contract choices land better when they reflect how you use power and gas through the year.

• Term and timing – aim for end dates that avoid peak sporting seasons, so retenders don’t collide with your busiest weeks.
• Volume clarity – if classes are growing, include a reasonable usage range to avoid penalties.
• Multi-site simplicity – if you run several centres, align end dates so you can manage them together and compare usage fairly.
• Billing transparency – ask for clear non-commodity breakdowns so you can see where network and policy charges hit you.

The goal isn’t to outguess the market. It’s to pick a contract you can run confidently while you improve the site.

Renewables fitted to daytime demand

Leisure roofs are often big, and pools pull steady daytime load.

• Solar PV sized to the pool plant and air handling units – prioritise self-use over export.
• Battery storage for predictable peaks – charge in off-peak or sunny hours, support evening sessions.
• Heat options – where the fabric and hydraulics allow, consider heat pumps or solar thermal for showers and pool hall air. Fix insulation on valves and pipework first, or you’ll pay to heat the plant room.
• EV charging – install charge points with load management so charging slows during pool and court peaks. If you have a fleet or staff charging, link sessions to cheaper time bands and publish clear rules so it never fights the building’s needs.
• Offsite options (PPAs) – if onsite isn’t feasible, a power purchase agreement is a contract to buy electricity from a renewable project (often for 5–15 years) at an agreed price structure. Your supplier usually handles delivery on your bill. It can give budget clarity and show progress without major works, but you’ll want to check term, pricing, and how volumes match your usage.

The aim is practical output that ties to your profile, not panels for the sake of it.

Efficiency upgrades that respect the session

Upgrades shouldn’t ruin a class or a match. Pick measures that drop in cleanly.

• LEDs that suit sport – low-flicker drivers, glare control for courts, daylight sensors in circulation areas.
• Variable speed drives on pool pumps and air handling - slow things when demand dips.
• Pool plant tuning – covers during still periods, heat recovery on ventilation, tight and checked set points.
• BMS tune-up – fix scheduling drift, sensor calibration and deadbands before spending big on new kit.
• Fabric care – draught control on poolside doors, proper seals, and insulation on the “forgotten” bits of pipework.
• Energy monitoring – sub-meter key areas (pool plant, gym, studios, café) and set simple alerts for nightline creep. A weekly 20-minute review of live data with the duty manager keeps settings honest and spots problems before they hit the bill.

Water and energy are the same bill

A small overnight leak can nudge both meters up. Set a simple nightline target for electricity, gas and water between 2–4am. If any creep up, find the cause fast, often a valve that doesn’t close or a timer that slipped.

Make progress visible to your community

People want warm pools, bright courts and clean air and they care how you achieve that.

• Share a “how we’re running” board: pool temperature range, air quality notes, upgrades done.
• Ask clubs to help with “session resets”: lights down, doors closed, kit off after bookings.
• Explain choices in plain words: “we start the plant 20 minutes later on quiet mornings to keep prices stable”.

When users see the trade offs and the action, they back you.

A timetable-led plan that reflects real life

It’s not a switch you flip. Treat it as a phased project with checks and ownership.

1. Map demand properly – pull a month of half-hourly data and lay it against the bookings diary. Mark where plant actually starts versus when sessions begin.
2. Define building “scenes” – write clear settings for quiet/standard/event: temperature bands, fan speeds, lighting levels, and which areas are live. Keep it on one page so duty staff can use it.
3. Set guardrails – nightline targets for electricity, gas and water; maximum pool hall humidity; minimum lighting levels for courts.
4. Pilot and adjust – test scenes on two quiet weekdays and one busy evening. Log any comfort issues and tweak set points and timing gaps.
5. Fit monitoring to the plan – add the sub-meters you need to see if scenes are working (pool circulation pumps, AHUs, spa, café). Create a simple dashboard showing today versus target.
6. Schedule upgrades around bookings – slot LEDs, VSDs and BMS work into maintenance windows. Publish the plan so clubs know what’s happening.
7. Align procurement – choose contract terms and volumes that fit your expected changes over the next 12–24 months, so savings aren’t masked by pricing surprises.
8. Review quarterly – compare costs, comfort and complaints. Retire what didn’t work, keep what did, and set the next round of improvements.
