On May, 26 I was listening to webinar regarding Richardsville NEZ school presented by Joanie Hendricks, Public Relations Coordinator from Warren County PS, Tim Murley Superintendent WCPS, Kenny Stanfield, AIA, Architect, Sherman Carter & Barnhart.
On page 39 of slide presentation they mentioned that "The HVAC uses heat sensors to determine how many people are in the room and can adjust the temperature for minimal usage."

Anybody knows what kind of sensor controls (manufacturer, brand) for HVAC are used in this school?
Thank you
