Annual Radiation

Annual radiation recipe for Pollination

This recipe calculates the annual radiation for each time step provided by a wea file. The outputs are stored under results/direct and results/total. Nighttime hours are filtered before running the simulation. To match the results for each of the hours, see the list of hours in sun-up-hours.txt.

Methods

This recipe calculates the total amount of Radiation by calculating the direct sunlight radiation from sun disks and adding them to the contribution from indirect sky radiation.

Total radiation = direct sun radiation + indirect sky radiation

The number of bounces for direct radiation is set to 0 and cannot be modified by the user. You can adjust the number of bounces for indirect sky radiation.

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 time steps 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.
