I’m calculating illuminance values for LEED daylight option 2. Based on the LEED guidance, I need to use average radiation inputs between clearest day of September(9/14~9/28) and the clearest day of March(3/14~3/28). But I couldn’t find a way to input average data of two days for diffuse&direct horizontal radiation.
FYI, please see the LEED example image below.
I just chose the clearest day between September(9/14~9/28) and March(3/14~3/28) for now. See my script below. But please help me to choose two clearest days and generate average data from the two days for the illuminance calculation. Grasshopper file is also has been attached for your reference.
Hi,
I did check now, sorry about it.
I saw that you mentioned gendaylit for these issues. But I couldn’t find gendaylit in my grasshopper.
Can you assume what is my issue and why I can see it? Is it custom component I need to create?
FYI, I’m using Radiance 5.2.2 and OpenStudio v2.5.0
Thanks.
But still not sure how I can use it. I can’t find it as a component in the grasshopper.
(Maybe it’s not a component? Am I on the totally wrong track to understand it?)
Thank you.
I read more post from the website and I’m a little bit confused. The gendaylit is a single component? or It means the category of HB-daylight which has genClimateBasedSky, genCumSky, and etc?
If it means the category of those components, I was using it. And I’ve tried genClimateBasedSky, genCumulativeSky, genAverageSky and genCustomSky, but I failed to create the average value of two selected hour of date. Please see the screen captured script above.
(I should create average-direct-horizontal-radiation of 9am-Mar.24th and 9am-Sep.23th. But I couldn’t find the way, so I just chose one day(9am.Mar.24th) just for now.)
