The VIP energy simulation software module integrated in ARCHICAD (a.k.a. engine) is a result of more than 20 years of research and commercial use. It relies entirely on dynamic models, in which every model is broken down to a level where facts and behavior are known. Each component group is analyzed separately. The calculation is repeated every hour. The accuracy of each model has been validated and verified against real buildings under real usage. In calculating a building’s energy consumption, the program utilizes known or measured facts about all parts of the energy flow.

Energy Evaluation uses the same simulation kernel as EcoDesigner STAR add-on for ARCHICAD. This kernel is validated with ANSI/ASHRAE Standard 140-2007: Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs.
Note: To produce code-compliant energy simulation results, the expert user interface of EcoDesigner STAR is necessary.
The ASHRAE Standard 140 test documentation for EcoDesigner STAR will be available on the official product website, following the add-on’s release.
The stand-alone VIP Energy product, which also uses the same simulation kernel as Energy Evaluation in ARCHICAD and EcoDesigner STAR, is also validated with the following tests:
