Parametric Study Using Dynamo

daylighting and PANELS reaction in Hall of the messe basel

It all stars with adding a new design intent to the hall of the messe basel

Expanding and shrinking the openings formed by the facade panels according to the sun location is achievable by controlling the height of the sine curves for each panel on the facade. As explained in the video below amplitude_factor is an instance parameter timed by the sine equation controlling the form of the panel based on the x angle. As such by focusing our scripting in dynamo on the manipulation of the amplitude factor according to the location of the sun we can reach panels of different shapes and forms due to their shrinkage and expansion.  Each panel distributed on the facade will have a normal vector which depending on its location makes a different angle with the sun vector. This angle can become the base for either shrinking or expanding the panel and its associated opening.

The video below better explains the parametric logic of this experiment and the behavior of the panels with respect to sun location.
