B0065-anneal-2-259

Simulated annealingC · meets all 17 benchmark constraints. Brief B0065

Plan drawing of a triplex on a 16.4 by 19.0 metre lot, 2 storeys, 3 dwellings, 17 rooms. Dwelling U0 (studio) has 4 rooms totalling 48 square metres. Dwelling U1 (1BR) has 5 rooms totalling 51 square metres. Dwelling U2 (2BR) has 6 rooms totalling 99 square metres. Building footprint 119 square metres; open space 200 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.95, daylight 0.61, privacy 0.86, circulation 0.50, carbon 0.78, cost 0.30.
