Efficient refrigeration
Tackle one of the most underestimated sources.
Refrigeration — fermentation control, cold stabilisation and storage — is one of the biggest and most underestimated sources, especially in warm climates. Cooling efficiency has two fronts: the energy consumed and refrigerant-gas leaks.
Right-sizing, insulating tanks and rooms, maintaining equipment and choosing low-warming-potential refrigerants reduces both. It is often a cellar’s single biggest efficiency opportunity.
Effort
Medium — investment in insulation and equipment.
Cost

How it works
Reducing cooling load and losses — through insulation, maintenance and good refrigerants — cuts energy and avoids direct leak emissions.
How to implement
- 1Insulate tanks and cold rooms.
- 2Right-size and maintain the cooling equipment.
- 3Monitor and repair refrigerant leaks.
- 4Log consumption and leaks for the footprint.
What to measure
Frequently asked
Do refrigerant leaks matter much?
Yes — many refrigerants have a warming potential hundreds to thousands of times that of CO₂, so small leaks weigh heavily.
How to reduce the cooling load?
Insulation, managing cellar ambient temperature, night-cooling recovery and good maintenance reduce the energy needed.
