Simulated annealingC · meets all 17 benchmark constraints. Brief B0023
Plan drawing of a triplex on a 13.5 by 27.4 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 33 square metres. Dwelling U1 (1BR) has 5 rooms totalling 60 square metres. Dwelling U2 (2BR) has 6 rooms totalling 93 square metres. Building footprint 101 square metres; open space 270 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.43, daylight 0.69, privacy 0.75, circulation 0.68, carbon 0.74, cost 0.30.
