These luminance maps show the brightness of surfaces adjacent to one another in different areas on the third floor, indicated in plan. Light areas on the maps indicate high luminance readings, or areas of high perceived brightness.
North side measurements
Northeast corner:
A few higher luminance readings, yet in general fairly dark
Due north:
Again, the area around the window is quite dark with some higher luminance in the middle of the glazing.
South side measurements
Due east:
Some sunlight is causing higher luminance readings on the windows.
Due south:
A large amount of sunlight is coming in despite the use of blinds, causing an extremely bright area on the left.
Southwest corner (blinds as adjusted by occupants):
Here the blinds are blocking much of the sunlight.
Southwest corner (blinds up): The sunlight coming through the south-facing window here was previously blocked by the blinds.
In general, the south side luminance measurements were brighter than those from the north side with south-facing windows receiving significant amounts of sunlight, as evidenced by extremely high luminance readings in these areas. Since these measurements were taken on a sunny morning, sunlight coming through south-and east-facing windows is to be expected. To determine whether this light is a potential glare problem, the luminance measurements must be compared to one another in ratios to find out whether high levels of contrast are present.
