Ah, sorry that I forgot there’s a little more of a difference between Annual Irradiance and Annual Daylight other than the multiplication by 179. The sky irradiance values are also different and I would be that accounts for the 1.6 difference that you’ve noticed.
So, yes, the right way to get the direct illuminance is by reconstructing the direct_sky files in the initial_results. I think we’ll add a step to do this in the recipe soon since we are planning to add ASE at some point. I think we just wanted to make it a little harder for people to get ASE right now because, if we tell people that they can get it, they are immediately going to think we can do LEED daylight, which is not going to be true until we implement dynamic window groups.
The only difference between the initial_results and the final results is that the sensor grids in the inital_results are split up for optimal parallelization whereas the final results are split based on the structure of the input sensor grids. If you really need direct illuminance right now, you can use this command to reconstruct the initial_results into final results.
