The explanations in both the COMIS and Energy+ users' manuals get a
little sketchy from time to time. I'd like to be sure I understand
how to enter upwind conditions when I have COMIS calculate its own
Cp values in Energy+. Both manuals speak of entering a given wind
direction for the program to reference in picking up the Plan Area
Density, Wind Velocity Profile and Surrounding Building Height. That
seems quite wierd to me since the meteorological files are in 1
degree increments. I can't believe I should enter 360 data sets. It
would seem more logical to enter a start angle at which a condition
(the three inputs listed above) applies and the the following entry
gives a new group of data to be applied until the next entry. If, on
the other hand, it is interpolating between entries you would need to
tweak your values to represent a maximum at some direction and then
minima at the borders to get a reasonable value across the span. Anyone
familiar with the actual source code who can explain how it actually
uses these inputs?
