[Radiance-general] Radiance - External Glare Study

[Tom Moyle]

Dear All,

I am looking for a method to investigate external glare from building facades using forward ray tracing to predict critical locations and then quantifying reflected daylight received at the critical positions with a backward ray tracing time-series simulation (reference paper attached - Yang et al. 2013, Simulation of Reflected Daylight From Building Envelopes). I have been using DIVA for Rhino/Grasshopper  but as far as I'm aware this is incapable of forward ray tracing to predict critical locations. Also as I am interested in reflected light primarily from the building being investigated at the locations of interest (rail corridor),  any glare studies I run at these locations do not provide the results I am after. As light direct from the sun is included in the results.

I'd appreciate any help in advice or in directing me to applicable Radiance docs.

I'm new to Radiance but have programming experience.


Thanks,

Tom
