NSGA-IID · meets all 17 benchmark constraints. Brief B0014
Plan drawing of a duplex on a 15.1 by 21.0 metre lot, 2 storeys, 2 dwellings, 14 rooms. Dwelling U0 (2BR) has 6 rooms totalling 83 square metres. Dwelling U1 (2BR) has 6 rooms totalling 83 square metres. Building footprint 96 square metres; open space 222 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.74, daylight 0.89, privacy 0.84, circulation 0.54, carbon 0.76, cost 0.29.
