Simulated annealingC · meets all 17 benchmark constraints. Brief B0047
Plan drawing of a triplex on a 13.2 by 21.0 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 44 square metres. Dwelling U1 (1BR) has 5 rooms totalling 52 square metres. Dwelling U2 (2BR) has 6 rooms totalling 96 square metres. Building footprint 107 square metres; open space 167 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.84, daylight 0.49, privacy 0.88, circulation 0.56, carbon 0.75, cost 0.35.
