Testing the Revit–EnergyPlus interoperability by the use of Ladybug tools.

Although a considerable number of studies on Building Information Modelling (BIM) have conducted in recent years, the theme is already widely recognized in the building sector, with perplexity in Energy Design. In this regard, the work proposes an automated early design workflow to evaluate the building daylighting performance during the first design stages. Thanks to the potential use of interchange files and visual coding tools, such as Grasshopper, it is possible to implement the parametric design concepts, thus automating complex tasks. In detail, in the analysed workflow, environmental algorithms and simulations are integrated to achieve reliable results with the minimum error percentage in data loss. The main finding concerns the BIM applications to perform daylighting design by the use of Ladybug tools from the Autodesk Revit export
