NSGA-IID · meets all 17 benchmark constraints. Brief B0066
Plan drawing of a adu pair on a 12.2 by 21.7 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 66 square metres. Dwelling U1 (1BR) has 5 rooms totalling 66 square metres. Building footprint 77 square metres; open space 177 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.91, daylight 0.42, privacy 0.93, circulation 0.55, carbon 0.71, cost 0.41.
