Why It Matters

Greenhouses vent warm, CO2-rich air to control temperature, wasting both heat and the fertiliser CO2 plants need. Sensible recovery keeps the energy while the gas stays in the canopy.

Typical Energy Savings

Recovering heat from vents can cut heating demand during cold nights by 20 to 40 percent and reduce supplemental CO2 dosing.

Recommended Technology

• Sensible plate cores - heat only, no moisture or gas transfer
• Run-around coils where airstreams must stay separate

What to Watch

• Humidity management to avoid condensation issues
• Control strategy that prioritises crop conditions
