8. Performance-based methodology Performance based design approach emphasizes the setting of project targets as functional targets of end product (building) and evaluation of fulfillment of these targets during design, construction and operation (CIB, 1982) 8 Sustainable Places 2014, October 1-3, Nice  DEDICATED CALCULATION ENGINES for building performance SIMULATION  MULTI-PHYSICAL SIMULATION ENGINE enabling the combination of the results coming from the different calculation engines by means of a multi-criteria analysis, thus providing the platform end-users with a quantitative measurements of the quality of the implemented design solution HOW BUILDING PERFORMANCE is considered within HOLISTEEC BIM-based software platform

9.  Simulation tools starting from concept design phase Energy calculation engine Acoustic calculation engine Environmental impact engine Lighting calculation engine Dedicate calculation engines 9 Sustainable Places 2014, October 1-3, Nice Currently experience and knowledge of the designers are used as a basis to choose design global optimum  the goal for HOLISTEEC is to transfer designers’ knowledge and experience in the software design decision tools, in order to provide recommendations to designers based on empirical, formalized design expertise.

Social interaction with neighborhood (Accessibility to the building, Pedestrian paths ) Cost development of buildings/neighborhood 13 Sustainable Places 2014, October 1-3, Nice

14. 14  Multi-physical simulation engine completed by a design assistant, providing online recommendations to the designer, enabling a semi-automated approach to design. Multi-physical simulation engine This tool will be based on a multi-criteria analysis enabling the assessment of the building with respect to the identified KPIs for each domain of interest.
