Testing the BIM-ladybug tools interoperability. A daylighting simulation workflow

While a considerable number of studies on Building Information Modelling (BIM) have been conducted in recent years, this area of research has long been considered important in the building sector, with particular concerns about Energy Design. In this regard, the work proposes an automated early design workflow to evaluate the building daylighting perfor¬mance during the first design stages. Thanks to the po¬tential use of interchange files and visual coding tools, such as Grasshopper, it is possible to implement the par¬ametric design concepts, thus automating complex tasks. Specifically, in the analysed workflow, environmental algo¬rithms and simulations are integrated to achieve reliable results with the minimum error percentage in data loss. The main finding concerns the BIM applications to per¬form daylighting design by the use of Ladybug tools from the Autodesk Revit export.
