NSGA-IID · meets all 17 benchmark constraints. Brief B0028
Plan drawing of a rowhouse on a 22.2 by 26.7 metre lot, 2 storeys, 3 dwellings, 27 rooms. Dwelling U0 (2BR) has 9 rooms totalling 116 square metres. Dwelling U1 (2BR) has 9 rooms totalling 135 square metres. Dwelling U2 (2BR) has 9 rooms totalling 193 square metres. Building footprint 222 square metres; open space 358 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.68, daylight 0.77, privacy 0.91, circulation 0.49, carbon 0.85, cost 0.63.
