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 63 square metres. Dwelling U1 (2BR) has 6 rooms totalling 73 square metres. Dwelling U2 (2BR) has 6 rooms totalling 136 square metres. Building footprint 148 square metres; open space 264 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.47, daylight 0.48, privacy 0.80, circulation 0.67, carbon 0.81, cost 0.58.
