[EnergyPlus_Support] Window Calculation
Dear E+ User
1) In the case of windows, the external film coefficient cannot be
set with the object ?ConvectionCoefficients?. This means, if a value is
defined, the output variable for the window external convection
coefficient is zero. Is this deliberate?
2) As defined on page 41 in the Output Details and Examples-
manual, the calculated conductance does not include film coefficients.
Comparing this result to the Window5 calculation, values are the same,
but the Window5 calculation includes film coefficients. Might it be
possible, that the E+ output for the U-Value includes the film
coefficient? In that case, can the window U-Value be assumed to be
constant, independent of the variable external convection coefficient?
I would appreciate your comments.
Alexander
