Revision history [back]

Hi all, I'm on the phase of analysing the DGP results obtained with evalglare from annual sample data.

I have two very simple questions about the glare classification method proposed by Wienold:

When evaluating the DGP occurence during the 95% of the working time, is not that clear for me if it should be considered the 'average' or the only the 'maximum' value of that sample.

Then, how to sample the data, should be randomly?

I mean, from a year of 2000 working hours, I should consider a random sample of 100 hours to estimate average DGP during the 5% of the time? Or, can that be selective? Since for instance winter time is more prone to achieve higher glare results.

I'd appreciate your help
