Now in terms of the glare control question, I would look at the useful daylight illuminance (UDI) rather than the mean illuminance. UDI illustrates the percentage of time a given space receives between 100 and 3,000 lux. I really like this metric, both for quantifying the, well, the utility of the daylight vis a vis energy savings from controls, but also the glare potential (or lack thereof), since the metric penalizes a design for over-illumination (>3,000 lux). This is using task plane horizontal illuminance as a proxy, but it's a reasonably quick way to look at a whole space or a whole building. You could also place glare sensors in your model and get annual vertical eye illuminance and draw your own conclusions that way. Unfortunately we do not have an elegant reporting measure that takes this daylight metric data and presents it to you like the default EnergyPlus output (this is a drag). You need to go into the text file output and parse it and visualize it some way, either with Excel or R or whatever. At any rate, the data can be found in the output directory of your run directory, e.g.:
[your_model]/run/[radiance_measure]-UserScript-0/radiance/output/daylight_metrics.csv
