Finer TimeSteps Do Not Work in HB+

[chris]

Or you could just use the latest LBT 1.4 plugin. The HB Annual Irradiance recipe over there is perfectly capable of handling Wea’s at finer timesteps. If you need sub-hourly illuminance instead of broadband solar irradiance, I’m willing to add a tweak to the recipe that will support this if you ask for it here:

Sub-annual daylight simulation with timestep other than 1

Hi @OlivierDambron , This is intentional because all of the methods that perform postprocessing on the illuminance matrices to produce DA and UDI rely on the analysis being at a timestep of 1 in order to have the illuminance values correctly aligned with the occupancy schedule. I was thinking that I would eventually add support for running the annual daylight recipe at a finer timesteps but it requires a significant refactor of these postprocessing methods and so it would take some time. So I …
