ASE CALCULATION

Thank you for your great program. I was wondering how to calculate the ASE with honeybee. I can get the grid based percentage of time over 1000 lux over the year but this is not exactly what ASE is, do you have any suggestions how it can be calculated using the honeybee components?

Hi Cheney,

Yes. It's possible to do it with Honeybee but there are technical issues with using Daysim for calculating ASE. Read Sarith comments here.

I can put an example together. You can use dynamic blind workflow and check the results for each hour but let me not do it until we have a Radiance-based workflow. Anytime that I have shared example files with caveats, even though I always clearly explained the limitations, I saw them being used by users without considering the limitations. Not everyone is knowledgeable as you.

Let us share the workflow with you once we have the Radiance based method ready :). Fortunately you have some alternative workflows for now to get it done.

Cheers,

Mostapha

There may be an alternative to using Radiance for the ASE calculations.

but since ASE doesnt need bounces of diffuse light, why don't anyone use the SunPath's SunVectors per hour and MeshRay or Occlusion to see, precisely, when different points in the grid are hit by the sun. I mean, in most cases, if there is direct sun, then it would be >1000 lux, if LT is not super low. As an extra, the solarIrradiation from the EPW file could tell what the direct-normal irradiation is.

If this could be set up in a multi thread workflow, it might be feasible ?
