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

Enter a value for all fields

The **Greenhouse Surface Area equation (Quonset shaped) **calculates the exterior surface area of a greenhouse based on simple measurements. This includes the roof and both ends.

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

- (L) Length of the greenhouse
- (H) Height of the greenhouse
- (W) Width of the greenhouse

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

The surface area calculation is a simple computation summing the lateral area sides of the green house defined by the semicircle of radius H times the roof area. The default input units are feet, and the calculator returns cubic feet. However, vCalc lets the user can choose one of many length and volume units for automatic conversion from the pull-down list for both the input length units and the output volume units.

- 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.
- Bell-shaped Greenhouse Volume and Surface Area: Computes volume, surface area, floor space and height based on dimensions.
- Greenhouse 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.
