NSGA-IID · meets all 17 benchmark constraints. Brief B0056
Plan drawing of a duplex on a 13.5 by 23.4 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (1BR) has 5 rooms totalling 76 square metres. Dwelling U1 (2BR) has 6 rooms totalling 76 square metres. Building footprint 87 square metres; open space 232 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.66, daylight 0.57, privacy 0.95, circulation 0.56, carbon 0.74, cost 0.40.
