Performance-based methodologyPerformance 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)


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


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.

HOLISTEEC- Key Performance Indicators 3

ECOLOGICAL KPI SOCIO-CULTURAL KPI ECONOMIC KPI

BUILDING SCALE Energy

consumptions(Heating/Cooling loads-Energy from renewable, Fossil fuels use)

Indoor comfort(Air flow rates- Room temperatures and humidity)

Maintenance Costs

Environmental impact(Greenhouse gas emission, Total primary energy consumption )

Visual comfort(Day Lighting Factor , Annual availability of daylight )

Operational cost(Energy and non-energy related)

-Acoustic comfort (Reverberation time, Airborne sound insulation)

-

NEIGHBORHOOD SCALE Energetic

interaction with neighborhood(Exploitation of local resources wind, sun, water..)

Social interaction with neighborhood(Accessibility to the building, Pedestrian paths )

Cost development of buildings/neighborhood

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.

PROJECT DETAILS 3D VIEW

ALTERNATIVES COMPARISON

Will provide assistance during design (options, missing data, risk analysis…)

Intuitive visualization of performance indicators of the various design options

Will offer 2D/3D views
