Grid> Polyexpand> Split> 'Make-Octogon'> Boolean Intersect (with site)> Boolean Intersect (with courtyard)> Split (different typologies)
Final results
Total number of buildings evaluated: 161
"Good" Building Ratio: 87.58%
"Good" Window Ratio: 54.80%
Passive Area Ratio: 100%
Unobstructed View Factor Ratio: 77.80%
Daylight Factor Ratio: 79.29%
Solar Factor Ratio: 80.89%
Conclusion
The Passive Area Ratio has improved a lot from iteration 2 (it is now 100%), and so have the "good" building ratios.
