B0010-anneal-0-1352

Simulated annealingC · meets all 17 benchmark constraints. Brief B0010

Plan drawing of a rowhouse on a 24.4 by 28.2 metre lot, 2 storeys, 4 dwellings, 36 rooms. Dwelling U0 (2BR) has 9 rooms totalling 135 square metres. Dwelling U1 (2BR) has 9 rooms totalling 131 square metres. Dwelling U2 (2BR) has 9 rooms totalling 177 square metres. Dwelling U3 (2BR) has 9 rooms totalling 166 square metres. Building footprint 304 square metres; open space 376 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.97, daylight 0.66, privacy 0.91, circulation 0.47, carbon 0.88, cost 0.65.
