I am trying to get a cumulative sky matrix for the whole year with only clear skies, is it possible to do with ladybug/honeybee?
The purpose of this is to be able to find the solar position that produces the peak solar heat gains in a specific room. For that purpose I cannot use a typical weather data file.
The alternative would be to buy a meteonorm license to get a weather file with only clear skies, but first I wanted to check if it was possible to solve this within LB/HB.
Thanks in advance!
I made an alternative version of the LB sunrise/sunset that calculates GHI, DNI, DHI by using Bird Clear Sky Model (R. Bird, R. Hulstrom) a couple of months ago.
I even made a cloudy sky version of Bird Model by following NREL’s formula, however it works just for GHI.
I have used a component which copies and modifies EPW files (http://www.grasshopper3d.com/group/ladybug/forum/topics/ladybug-wea…), and I used the results which come from Bird Model. Probably it works, but I have to see if the results are good enough.
