Why One HVAC Zone Doesn't Suit a Leisure Centre?

A pool hall runs hot, humid, and close to constant occupancy. A function room might sit empty most of the week and full on a Saturday night. A cafe has its own cooking and occupancy load. Treating all of these as one HVAC zone means the system is always compromising somewhere: overcooling the empty function room to keep the busy pool hall comfortable, or the other way around.

iZone zoning solves this by letting each space run to its own setpoint and schedule from the same ducted system, rather than requiring a separate system per space. iZone zoning is manufactured by iZone, whose smart zoning systems support the multi-space control this piece is about.

Energy Cost Benefits of Zoning Varied-Use Spaces

The energy case for zoning a multi-space building is straightforward: conditioning an empty function room or unused meeting space to the same setpoint as an occupied pool hall wastes energy for no comfort benefit. Individual zone control lets each space be conditioned only when and how it's actually used, which matters more in a building like a leisure centre where occupancy swings hard between a quiet Tuesday morning and a full Saturday timetable.

What Zoning Looks Like Day to Day?

A leisure centre's occupancy pattern rarely looks the same two days in a row. A Tuesday morning lap swim session might mean a full pool hall and an empty function room, while a Saturday birthday party booking flips that around, a packed function room and a quieter pool hall in between school holiday programs. A zoned system tracks that pattern instead of averaging it out. Each zone can run its own schedule, so the function room only conditions ahead of a booking rather than sitting on standby all week, and the pool hall keeps running its own setpoint regardless of what else is happening on site. For a facility manager, that means fewer manual overrides and fewer complaints about a space that's too hot, too cold, or running when nobody's using it.

How Zoning Interacts With Dehumidification in Aquatic Environments?

Pool halls need dedicated dehumidification running alongside standard air conditioning, and zoning needs to account for this rather than treat the pool hall the same as a dry space.

iZone zoning allows the pool hall zone to run its own schedule and setpoint independent of dry spaces like change rooms, cafes, and function rooms elsewhere in the same building, which supports the dehumidification and condensation control aquatic environments need. See our page on HVAC and dehumidification ducting for aquatic centres for more on the ducting side of this.

The Contractor's Role in Specifying Zoning at Design Stage

Zoning needs to be planned at the design stage, not retrofitted once ductwork is installed. Confirming zone boundaries against the building's actual spaces, pool hall, change rooms, cafe, function room, plant areas, alongside the commercial hvac ducting supplier scope for the project means the ducting and controls are specified to suit the zoning plan from the start, rather than working around a system that's already been sized.

Retrofitting Zoning Into an Existing Leisure Centre

Not every zoning project is a new build. Plenty of leisure centres and community facilities operate on an older system that was never designed to treat the pool hall, change rooms, and function spaces differently, and retrofitting zoning into an existing ducted system is usually more straightforward than it sounds. It typically comes down to confirming where the existing ductwork already separates each space (or where it needs modification to do so), then fitting the controllers and sensors that let each zone be managed independently. A site visit or a set of as-built drawings is usually enough for our team to advise whether a straightforward retrofit will work or whether some ducting rework is needed first.

Get Zoning Confirmed Alongside Your Ducting Quote

Our HVAC estimation service can confirm iZone zoning alongside ducting takeoffs and material specification for your leisure centre or multi-space commercial project, so zoning and ductwork are quoted together rather than as separate line items.

iZone Zoning FAQs

Q. How does iZone zoning work in a leisure centre or multi-space building?

iZone lets each space in a building, such as a pool hall, change rooms, cafe, or function room, run to its own setpoint and schedule from one ducted system, rather than treating the whole building as a single zone with one comfort setting.

Q. Does zoning reduce energy costs in a multi-use commercial building?

Yes. Zoning means spaces are only conditioned when and how they're actually used, rather than running an empty function room or meeting space to the same setpoint as a busy occupied area, which is where most of the energy saving comes from.

Q. Can iZone zoning work alongside dehumidification systems in pool halls?

Yes. A pool hall zone can run its own schedule independent of dry spaces elsewhere in the building, supporting the dehumidification and condensation control that aquatic environments need without compromising comfort in the rest of the site.

Q. When should zoning be specified for a leisure centre or multi-space project?

At design stage, ideally alongside the ducting design and HVAC estimation, so zone boundaries match the building's actual spaces rather than being retrofitted once ductwork is already installed.

Q. Can iZone zoning be retrofitted into an existing leisure centre, or only specified in new builds?

Both. Retrofitting zoning into an existing ducted system is usually straightforward once we've confirmed how the current ductwork separates each space. A site visit or as-built drawings are typically enough to advise whether a retrofit will work as is or needs some ducting rework first.

Q. Is Vic Air an iZone supplier for commercial and leisure projects across Victoria?

Yes. Vic Air supplies iZone zoning solutions for leisure centres, aquatic centres, and other multi-space commercial buildings across Melbourne, regional Victoria, and southern NSW.
