B0012-anneal-2-374

Simulated annealingC · meets all 17 benchmark constraints. Brief B0012

Plan drawing of a adu pair on a 16.6 by 21.5 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 93 square metres. Dwelling U1 (1BR) has 5 rooms totalling 93 square metres. Building footprint 113 square metres; open space 246 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.84, daylight 0.74, privacy 0.97, circulation 0.46, carbon 0.80, cost 0.58.
