Description

technical field

[0001] The invention relates to the technical field of architectural optimization design, in particular to an optimization method for architectural multi-performance-oriented design. Background technique

[0002] Decision-making in the architectural design stage will involve a variety of building performance indicators, which affect and even determine the future performance of the building. There may be a competitive relationship between different building performance indicators, so different design orientations should be considered in building design to improve the overall performance of the building. Factors affecting building performance involve the thermal insulation performance of the exterior wall, air tightness, window-to-wall ratio, and building orientation, which are characterized by high dimensions, high uncertainty, and interaction. The interaction among these influencing factors constitutes a very complex design space, so how to identify the opti...
