Hi,

I just wonder if Accelerad is validated against CIE 171:2006 same as Radiance?

Best regards,

Hi Frank,

Accelerad is validated against Radiance and against physical measurements as described in a number of papers available on the website.

A few validation cases of note:

• Against both Radiance rpict and HDR photography: http://www.ibpsa.org/proceedings/BS2015/p2461.pdf
• Against Radiance rpict and HDR photography for glare evaluation: https://doi.org/10.1016/j.buildenv.2016.08.023
• Against Radiance rcontrib and Daysim for annual glare analysis: http://www.ibpsa.org/proceedings/BS2017/BS2017_259.pdf
• Against Radiance rpict for AcceleradRT progressive rendering: http://web.mit.edu/sustainabledesignlab/publications/1121-Jones01.pdf

All of these are summarized in Validated Interactive Daylighting Analysis for Architectural Design.

I'm not aware of any validation tests against CIE 171:2006. These are usually done by 3rd parties.
