NSGA-IID · meets all 17 benchmark constraints. Brief B0068
Plan drawing of a duplex on a 16.9 by 19.4 metre lot, 2 storeys, 2 dwellings, 12 rooms. Dwelling U0 (1BR) has 5 rooms totalling 85 square metres. Dwelling U1 (1BR) has 5 rooms totalling 85 square metres. Building footprint 95 square metres; open space 234 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.58, daylight 0.78, privacy 0.96, circulation 0.57, carbon 0.76, cost 0.56.
