The everyday opportunity
Offices, hotels, and mixed-use buildings run ventilation around the clock with high fresh-air rates. Recovering that exhaust energy is the single biggest HVAC saving for most commercial stock.
Technology mix
- Offices – balanced AHUs favor plate or rotary recovery; see AHU recovery.
- Hotels – guest-room ventilation plus laundry and pool loads; pair with retail et leisure recovery ideas.
- Mixed-use – a central plant with district-style sharing wins.
Climate matters
Use climate-based selection: enthalpic cores in humid zones, sensible plate in dry ones. Keep wheel upkeep in mind if you choose rotary.
Retour sur investissement
Most commercial retrofits pay back in 3-5 years. Size with our payback method and verify with efficiency metrics.
Where the savings come from
- Make-up air pre-conditioning – the largest load in continuously ventilated buildings.
- Reduced boiler and chiller runtime, especially during shoulder seasons.
- Smaller HVAC plant if recovery is specified early in design.
Specification tips
Favor sensible plate cores in dry climates and enthalpy wheels where humidity control dominates. Size the core from measured airflow, not nameplate, and keep a maintenance window for filter and wheel service.
Questions fréquemment posées
What payback can commercial buildings expect?
Most retrofits pay back in 3-5 years through lower heating, cooling and fan energy.
Plate or rotary for an office AHU?
Balanced offices usually suit plate or rotary; choose rotary when humidity recovery matters, plate when contamination control is tighter.
Do hotels need special handling?
Guest rooms, laundry and pools add latent loads, so enthalpy recovery often pays; pair it with the building central plant.
