Savings (x1000 kWh)

Compared to Indoor Grow

Consumption (x1000 kWh)

Energy savings is based on a facility located in Broomfield Colorado (Latitude: 40.13, Longitude: -105.24) with a designed temperature inside the facility about 80°. The outside weather data comes from the weather station of Broomfield, Co. We used an average weather of 8700 hours (in total) during the different years 1979, 1980, 1981, 1986, 1987, 1988, 1989. The ground temperature produced with a standard diffusivity of 2.32257 E -03 (m²/day).

Consumption Breakdown

Consumption (x1000 kWh)

Total consumption for running a CERES Greenhouse: 137,057 kWh

Standard Design

Standard design means vented, and requires a lot of heating on cold days but no cooling; even in summer.

Consumption (x1000 kWh)

Total consumption for running a Standard Greenhouse : 151,200 kWh (+4%)

Indoor Room

Totally sealed facility. Expensive to run. The supplemental lighting is the highest expense in this type of building where there is no sun.

No Savings - Full Consumption

Consumption (x1000 kWh)

Total consumption for running an Indoor Grow Room: 370,800 kWh (+63%)
