NSGA-IID · meets all 17 benchmark constraints. Brief B0046
Plan drawing of a rowhouse on a 19.9 by 22.1 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 78 square metres. Dwelling U1 (3BR) has 11 rooms totalling 154 square metres. Dwelling U2 (2BR) has 9 rooms totalling 93 square metres. Building footprint 162 square metres; open space 277 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.79, daylight 0.71, privacy 0.90, circulation 0.49, carbon 0.79, cost 0.35.
