Calculated tab on Constructions Dialog.
This tab provides further information on the heat transmission properties of the construction.
U-values and R-Values are shown including and excluding the effect of surface resistance and are calculated with and without bridging effects.
Note that when working with library constructions, the outer surface resistance is calculated assuming a 'typical' exposure to wind. When working with model constructions the outer surface resistance is calculated using the wind exposure as defined on the Location tab at site level.
The convective heat transfer coefficients displayed on this tab are only used in EnergyPlus when the 'CIBSE' Inside/Outside convection algorithm is selected. Otherwise EnergyPlus uses its' own convection algorithm as set in the simulation options and the transmission data displayed here is not used.
