NSGA-IID · meets all 17 benchmark constraints. Brief B0026
Plan drawing of a duplex on a 13.6 by 18.3 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (1BR) has 5 rooms totalling 67 square metres. Dwelling U1 (2BR) has 6 rooms totalling 67 square metres. Building footprint 76 square metres; open space 175 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.84, daylight 0.76, privacy 0.96, circulation 0.55, carbon 0.71, cost 0.30.
