Grasshopper video tutorials

This video shows the Urban Daylight software in action. It covers the component setup, exterior raytrace and impulse simulation.

This video shows the various outputs and metrics that are available. Spatial Daylight Autonomy (sDA,) Continuous Daylight Autonomy (cDA) as well as accumulated radiation on the envelope are covered.

Advanced Topics:

This video shows how to model punctuated facades with a simple cosine function.

This video shows how to model orientation dependent facades with the Hula Hoop component of the Urban Daylight package. Based on the orientation vector of each facade patch the aperture can be modified withing the min/max boundaries.

This video shows a window to wall ratio optimization process. Based on an initial result window to wall ratios are scaled locally based on the light flux between facade and interior sensor.
