Good evening everyone,
I’ve been redirected here from the McNeel Forum.
I’m quite new to grasshopper and HB&LB, I have a question. I premise I saw something similar in the forum, but i did not understand if it applies to my issue (I’m referring to: Illuminance discrepancy from Honeybee grid based, Honeybee[+] grid based, and Honeybee[+] annual), if so I apologize for the inconvenience.
Currently I’m performing some daylight analysis on a case study for my thesis degree and I encountered a problem: I found some discrepancies between the illuminances values (calculated using the “Honeybee_Grid Based analysis” component with the Climate Based sky) and those I can read using the “Honeybee_Read hourly results from Annual daylight study”. I’m using the same model and the same epw file and I’m confronting illuminances values for the same day, month and hour. If you confront the values for March the 20Th the differences are small, but if you repeat the comparison for December the 21St the values are quite different. Could you explain me if I’m doing something wrong? I do not know which values I can interpret as correct.
Thank you for your kind help.
PS I tried uploading my .gh file here, but its size is over the 1.5 Mb limit. So I’m providing the link to the McNeel forum where you can find the .gh file (https://discourse.mcneel.com/t/grasshopper-discrepancies-between-the-illuminances-values-read-from-ds-annual-analysis-and-calculated-with-climate-based-sky-on-an-analysis-grid/73904). I tried compressing it but it didn’t work, sorry for the trouble and again thanks for the help.
PPS if anyone knows a way to upload the file (despite the oversize issue) I will upload it immediately.
