NSGA-IID · meets all 17 benchmark constraints. Brief B0038
Plan drawing of a duplex on a 14.4 by 20.5 metre lot, 2 storeys, 2 dwellings, 12 rooms. Dwelling U0 (1BR) has 5 rooms totalling 63 square metres. Dwelling U1 (1BR) has 5 rooms totalling 63 square metres. Building footprint 75 square metres; open space 221 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.49, daylight 0.87, privacy 0.75, circulation 0.56, carbon 0.71, cost 0.18.
