B0036-anneal-0-1258

Simulated annealingC · meets all 17 benchmark constraints. Brief B0036

Plan drawing of a adu pair on a 16.3 by 19.9 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 78 square metres. Dwelling U1 (1BR) has 5 rooms totalling 78 square metres. Building footprint 98 square metres; open space 226 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.59, daylight 0.62, privacy 0.96, circulation 0.46, carbon 0.77, cost 0.32.
