920 sq.ft (23′ x 40′) Grow Area

Savings (MWh)

Compared to Indoor Grow

Consumption (MWh)

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

Detailed for a 920 sq.ft area

Ceres Design

Most efficient design: the building itself is a thermal battery, therefore reducing heat in the winter months.

Consumption (MWh)

Total consumption for running a CERES Greenhouse: 100 MWh

Standard Design

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