Under the hood

EIA average. Real compressor math.

Baseline 20 kWh per cubic foot per year matches typical wine-cooler energy guide labels. Cost uses the EIA US residential average ($0.13/kWh).

  1. 01

    Single-zone baseline

    Cubic feet × 20 kWh/yr, then ±10–15% based on usage intensity (light / moderate / heavy).

  2. 02

    Multi-zone adjustment

    Each zone above one adds 10% to baseline kWh, then a 5% reduction for smart per-zone setpoints.

  3. 03

    Annual cost

    Yearly kWh × $0.13 = annual operating cost. Difference column shows the multi-zone premium.

Questions

Frequently asked

Each independent zone has its own thermostat and either a second cold loop or an extra evaporator. That additional control hardware adds roughly 10% to baseline kWh per added zone in our model.
