Finding area of the contours of the ecotect analysis grid was something which I had to do for my dissertation relating to lighting analysis in atriums and the adjacent spaces. One of the grids whose area I had to find for the different bands of daylight factors is:
One of the easiest methods is clicking on the following:
REPORT > REPORT GENERATOR > Analysis Grid > Percentage Contours
which presents the following screen:
At the first glance, the table here gives the information we require, very nicely formatted as well. On a closer look, what it is doing is just adding the number of grid points which fall between a particular range (daylight factors from 0 to 10 in this case) and give the percentage from the total number of grid points. According to this report, no part of the floor get daylight factors in the range of 9-10.
