NSGA-IID · meets all 17 benchmark constraints. Brief B0041
Plan drawing of a triplex on a 15.9 by 25.9 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 87 square metres. Dwelling U1 (2BR) has 6 rooms totalling 101 square metres. Dwelling U2 (2BR) has 6 rooms totalling 188 square metres. Building footprint 204 square metres; open space 215 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.85, daylight 0.32, privacy 0.81, circulation 0.68, carbon 0.87, cost 0.72.
