Two innovations have more deeply changed the building process: the operational continuity of the design and construction phases and the software allowing not only the representation but also the autonomous creation of complex shapes never before thought, just because they could not be represented. This last innovation introduce to a “Performative Architecture” that addresses to emerge a new kind of architecture. Building performances (structural, environmental, energetic) are guiding design principles, adopting new building performance-based priorities for the design of cities, buildings and landscape. This emerging architecture places broadly defined performance above form making, It utilises digital technologies of quantitative and qualitative performance-based simulation to offer a comprehensive approach to the design of the build environment. Some aspects of “Performative Architecturei theories are critically examined and we report two experiments made using these procedures. The results try to give a contribution to detect some misunderstandings in relation to recent building projects shown
