Multicriteria and multiple actors tool aiding to optimise building envelope at the architectural sketch design

The PC software AMCE is proposing building actors (owner, project authors…) a Multiple Criteria Decision Aid procedure (MCDA) to optimise the building envelope about cost and energy performances, during the sketch design. Two main modules are linked, where the user interactively goes: the first one manages parameters describing the project requirements; the second, the graphic pen-based module, allows the user to draw the sketch; it calculates geometric parameter values and puts them back in the first module. Permanently informed on forseeable performances, the user can any time search for optimal scenario giving best satisfaction (monoactor optimisation) or most preferred compromise (multiactors optimisation).
