Simulation tools starting from concept design phase • Energy calculation engine • Acoustic calculation engine • Environmental impact engine • Lighting calculation engine Sustainable Places 2014, October 1-3, Nice 9 Key Performance Indicators Assessment of the process performance Comparison among different performances Communication in a concise and understandable way process achievements In the framework of HOLISTEEC BIM based software PLATFORM: Strategic importance of KPI in order to assess the quality of the results coming from the building performance simulations Sustainable Places 2014, October 1-3, Nice 10 HOLISTEEC Key Performance Indicators 1 Considering HOLISTEEC project, definition of strategic Key Performance Indicators at different scale Link Editor Building scale Neighborhood scale Solar Renewable Energy gain Environmental noise, Natural daylight gain Building approach Building neighbourhood approach The domains included in the project evaluation framework are: Acoustic comfort Visual comfort Indoor air quality Thermal comfort and energy efficiency Sustainable Places 2014, October 1-3, Nice 11 HOLISTEEC- Key Performance Indicators 2 Boundary conditions Building simulation Urban simulation Solar potentials Rooftop solar gain Façade lighting Energy Lighting Environmental impact Façade noise 4 engines in parallel Acoustic Urban noise Sustainable Places 2014, October 1-3, Nice 12 HOLISTEEC- Key Performance Indicators 3 BUILDING SCALE ECOLOGICAL KPI SOCIO-CULTURAL KPI ECONOMIC KPI Energy consumptions Indoor comfort Maintenance Environmental impact Visual comfort (Air flow rates- Room temperatures and (Heating/Cooling loads- humidity) Energy from renewable, Fossil fuels use) (Greenhouse gas emission, Total primary energy consumption ) NEIGHBORHOOD Energetic SCALE interaction with neighborhood (Exploitation of local resources wind, sun, water..) Sustainable Places 2014, October 1-3, Nice Costs Operational cost (Day Lighting Factor , Annual availability (Energy and non-energy related) of daylight ) Acoustic comfort (Reverberation time, Airborne sound insulation) - Social interaction with neighborhood Cost development of buildings/neighborhood (Accessibility to the building, Pedestrian paths ) 13 Multi-physical simulation engine Multi-physical simulation engine completed by a design assistant, providing online recommendations to the designer, enabling a semi-automated approach to design. 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. 14 KPI Scoreboard Will provide assistance during design (options, missing data, risk analysis…) Intuitive visualization of performance indicators of the various design options HOLISTEEC SCOREBOARD PROJECT DETAILS 3D VIEW Will offer 2D/3D views ALTERNATIVES COMPARISON Sustainable Places 2014, October 1-3, Nice 15 Thank you for the attention!
