NSGA-IID · meets all 17 benchmark constraints. Brief B0005
Plan drawing of a triplex on a 15.8 by 20.8 metre lot, 2 storeys, 3 dwellings, 18 rooms. Dwelling U0 (1BR) has 5 rooms totalling 50 square metres. Dwelling U1 (1BR) has 5 rooms totalling 49 square metres. Dwelling U2 (2BR) has 6 rooms totalling 99 square metres. Building footprint 110 square metres; open space 222 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.60, daylight 0.70, privacy 0.78, circulation 0.65, carbon 0.76, cost 0.29.
