The figures referred to as ‘Average daylight factor required by latitude (degrees)’ in Table 10 for sales areas in retail buildings are intended to relate to ‘point daylight factors’ to be achieved for each latitude. Therefore, please ignore the note on point daylight factor stated in the ‘other requirements’ column of the Table.
We apologise for the confusion it may cause.
This will be amended in the re-issue of the technical manual.
