R-Value With Air Films
Use this component to account for air films in the U-Value and R-Value of any decomposed Honeybee construction or material.
Note that EnergyPlus has its own means of calculating the effects of air films on either side of a construction but, here, we provide an apporximate method based on an input surfaceType_.
Inputs

| U Value SI | _uValue_SI | The U-Value_SI out of either the "Honeybee_Decompose EP Construction" or the "Honeybee_Decompose EP Material." | Goo |
| Surface Type | surfaceType_ | An integer value from 0 to 3 that represents one of the following surface types: 0 - Exterior Wall/Window 1 - Interior Wall/Window 2 - Exterior Roof 3 - Exposed Interior Floor | Goo |
