Finding area of contours in Ecotect/Radiance analysis grid

The Real Fiction

All that we experience, our perceptions – sights & insights – seem like a surreal mix of fact and fantasy. There are no lines dividing anything anywhere & existence rides upon interpretations. This blog will surf, fly, jog, dive, swim, jump & at times even hobble through planes of experiences that will include poetry, protests, design, tales, photo-tales and whatever else is discovered & needs to be shared.

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:

Find the area of the contours

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.
