Sorry for the self promotion, but many on this list may be interested in a review paper written by my advisors and me. It reviews the current best practices and limitations with calculating discomfort glare across multiple positions and time-steps. I would recommend it both to researchers and practitioners who want to understand why annual glare simulations take so long compared to daylight autonomy, under what conditions fast methods are valid, and the range of approaches that have been attempted for simulation based glare assessment.
I would of course also appreciate any feedback!
