CP-SATE · meets all 17 benchmark constraints. Brief B0062
Plan drawing of a duplex on a 16.1 by 18.5 metre lot, 2 storeys, 2 dwellings, 13 rooms. Dwelling U0 (1BR) has 5 rooms totalling 104 square metres. Dwelling U1 (2BR) has 6 rooms totalling 82 square metres. Building footprint 108 square metres; open space 188 square metres. This design satisfies every benchmark hard constraint. Objective scores, higher is better: density 0.76, daylight 0.68, privacy 0.78, circulation 0.80, carbon 0.71, cost 0.32.
