NSGA-IID · meets all 17 benchmark constraints. Brief B0007
Plan drawing of a courtyard on a 21.7 by 21.6 metre lot, 2 storeys, 4 dwellings, 25 rooms. Dwelling U0 (1BR) has 5 rooms totalling 65 square metres. Dwelling U1 (2BR) has 6 rooms totalling 69 square metres. Dwelling U2 (2BR) has 6 rooms totalling 69 square metres. Dwelling U3 (2BR) has 6 rooms totalling 65 square metres. Building footprint 162 square metres; open space 299 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.42, daylight 0.57, privacy 0.84, circulation 0.55, carbon 0.70, cost 0.19.
