Direct sun hours recipe for Pollination.

Direct sun hours for Pollination

Calculate the number of hours of direct sunlight received by grids of sensors during the year. The recipe generates 3 subfolders under results folder:

1. direct_sun_hours: Hourly results for number of hours that each sensor is exposed to sun. The units are the timestep of input wea file. For an hourly wea each value corresponds to an hour of direct sunlight.

2. cumulative: The cumulative number of hours for each sensor during all the timesteps. The value is a single integer for each input sensor.

3. direct_radiation: Hourly direct radiation from sun. This output does not include the indirect sky radiation. For total radiation see annual radiation or annual sky radiation recipes.

Limitations

This recipe is limited to calculating up to 9999 number of suns at a time. This means you might need to break down the annual studies with smaller timesteps into smaller runs. This limitation is a result of how Radiance sets a limit on number of modifiers in a single run. See here. We can address this limitation by either building our own version of Radiance or breaking down the modifier list and looping over them and merging back the results.
