EcoDesigner STAR is built to serve highly energy-efficient building design by turning ARCHICAD Building Information Models (BIM) into multiple thermal zone Building Energy Models (BEM). Architects can now enjoy the benefits of high- end building energy performance simulation and reporting without leaving ARCHICAD. Low and net-zero energy building design is made easy for architects worldwide with EcoDesigner STAR's standard compliant energy simulation engine, advanced energy model visualization and documentation. In addition to the integrated energy simulation functionality, EcoDesigner STAR's advanced BEM export interfaces (such as gbXML and PHPP) allow full collaboration workflow with building energy consultants and enable data export from ARCHICAD to local building energy code compliance calculation applications. EcoDesigner STAR utilizes a custom dynamic building simulation method that is valid worldwide. This allows users to precisely evaluate building energy performance in any climate or location.
