After setting the small squares, the assessor may take
illuminance measurement at the centre of each square with
a luxmeter. The results indicate whether the lighting is
evenly distributed. In addition, the average value of these
measurements represents the average illuminance for the
whole work area. To evaluate whether an appropriate level
of illuminance is provided for the purpose, the average
value should be compared with the optimum average Readers should also note that two work areas with two
different work activities should be separately evaluated. In
other words, the office and the storage room of a company
should be separately measured and assessed.
