B0000-anneal-0-623

Simulated annealingC · meets all 17 benchmark constraints. Brief B0000

Plan drawing of a adu pair on a 16.5 by 19.9 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (2BR) has 6 rooms totalling 96 square metres. Dwelling U1 (1BR) has 5 rooms totalling 96 square metres. Building footprint 118 square metres; open space 211 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 1.00, daylight 0.64, privacy 0.77, circulation 0.53, carbon 0.81, cost 0.55.
