`Greenhouse_"surface area" = f( "L" "W" , "H1" , "H2" )`

Enter a value for all fields

The **Surface Area of a Greenhouse (arched roof)** calculator computes the exterior surface area of a greenhouse based on simple measurements.

**INSTRUCTIONS:** Choose the preferred units and enter the following:

- (W) Width of the greenhouse (under the gable).
- (L) Length of the greenhouse (perpendicular to gable).
- (H
_{1}) Height of main area - (H
_{2}) Height of the gable

**Greenhouse Surface Area (SA):** The calculator returns the surface area in square feet. However, this can be automatically converted to other area units via the pull-down menu.

The surface area of a greenhouse is useful in many ways including the calculating material needs and convection heat loss.

**Greenhouse or High-tunnel Calculators**

- Volume of a Gabled Greenhouse: Enter the dimensions of a gabled building and compute the cubic feet volume.
- Volume of an Arched Roofed Greenhouse: Enter the dimensions of an arched roofed building (see diagram) and compute the cubic feet volume.
- Volume of a Quonset Hut Greenhouse: Enter the dimensions of the Quonset Hut and compute the cubic feet volume.
- Surface Area of a Gabled Greenhouse: Enter the dimensions of a normal gabled building and compute the square feet surface area.
- Surface Area of an Arched Roof Greenhouse: Enter the dimensions of an arched roof building and compute the square feet surface area.
- Surface Area of a Quonset Hut Greenhouse: Enter the dimensions of a Quonset Hut and compute the square feet surface area.
- Green House Air Flow: Computes the air flow volume at the fan, middle and end of the greenhouse and the Evaporative Cooling Efficiency
- Conductive Heat Loss: Enter the surface area, the heat loss coefficient for the surface material and the maximum heat range, and the calculator will compute the BTUs per hour needed to heat the inside.
