Fenestration assembly and building service control with the same
A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.
