- This is an annual DGP calculation (Daylight Glare Probability).
- DGP is calculated against a threshold of 0.45. This can be changed in Project Settings > Climate Daylighting > EN17037 Criteria.
- Each grid point in the room will have multiple view points (6 by default). This can be changed in Project Settings . Climate Daylighting > Annual DGP views per point.
- The visual result as shown in the image shows the % of time each view point exceeds the threshold of 0.45
Excel Report
- SGA Pr % of views column shows the total % of the view points which are exceeding the req % of hours.
- If the view’s DGP is more than 5% target, it will be counted towards the PR % of SGA for the room e.g. SGA Pr % of view 10 % means that 10% of 1026 points (102 points) exceed the 0.45 DGP for at least 5% of the time.
- Avg DGPs column shows the Average Percent of time the DGP is more than the target for the room. (Average of Average DGP for each point)
