Our contribution

SageGlass can be tinted according to occupants’ and spaces’ requirements, through automated (Part 1: Automated Sunlight control) or manual control. 

In the automated mode, the tint is controlled by exterior sunlight sensors, which detect whether there are glare conditions or cloud cover. The automated mode can also take into consideration occupancy and seasons for improved energy savings.
