B0022-anneal-0-371

Simulated annealingC · meets all 17 benchmark constraints. Brief B0022

Plan drawing of a rowhouse on a 18.3 by 25.5 metre lot, 2 storeys, 3 dwellings, 29 rooms. Dwelling U0 (2BR) has 9 rooms totalling 102 square metres. Dwelling U1 (3BR) has 11 rooms totalling 206 square metres. Dwelling U2 (2BR) has 9 rooms totalling 91 square metres. Building footprint 199 square metres; open space 269 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.81, daylight 0.68, privacy 0.88, circulation 0.56, carbon 0.84, cost 0.44.
