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.

The study of a pre-tunnel structure that filters the daylight has been carried out by means of 3D daylight simulation software. The 1:1 scale model of the tunnel and the pre-tunnel has been realized and two different sequences of filtering panels have been simulated. The first sequence reproduces the panels experimented in a previous study with a real scale model; the second sequence is aimed to optimize the filter effect, acting on the grid of the panels.
