A major enhancement of DIALux affects the UGR calculation. It can produce the following UGR results:
1) The UGR table for all luminaires with direct lighting with a spacing to height ratio (SHR) of 0.25 or 1.
2) The single sheet output and the summary of “standard rooms” (rectangular, without furniture, only one type of luminaire) shows the four standard UGR values for the left wall and the lower wall viewing lengthways and across the luminaire axis. This saves doing the manual calculation with the help of the standard table.
3) You can place UGR observers at workplaces to get UGR values with respect to
a. position and viewing direction
b. all used luminaires
c. position and rotation of the luminaires
d. shadowing and reflection
4) With UGR calculation areas you get the distribution of the UGR values on an area. The calculation is comparable to the calculation of UGR observers. The output lists information about local glare problems on arbitrary places in the room.
The output of part 1 is a table of the corresponding values. For part 2 and part 3 you get single UGR values. For part 4 you get isolines and greyscale diagram, a chart and a table of the values. Possible UGR values are between 10 and 30. Smaller values are shown as < 10. Larger values are shown as > 30.
