NSGA-IID · meets all 17 benchmark constraints. Brief B0065
Plan drawing of a triplex on a 16.4 by 19.0 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 36 square metres. Dwelling U1 (1BR) has 5 rooms totalling 48 square metres. Dwelling U2 (2BR) has 6 rooms totalling 85 square metres. Building footprint 96 square metres; open space 214 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.66, daylight 0.76, privacy 0.79, circulation 0.59, carbon 0.73, cost 0.08.
