Demand Controlled Ventilation (DCV) saves energy by regulating air-flow according to occupancy measured with CO2 Sensors. DCV is a $4B market growing at 30% each year.
The built environment accounts for 30% of greenhouse gases in developed countries. Nearly half of this is for space conditioning: heating, ventilation, cooling, and humidity control. Most buildings have some variation in occupancy throughout the day and week. Yet most buildings have a fixed daily schedule of full-on and full off operation, regardless of the actual occupancy.
LightSense low power, long lived sensors expand the addressable market. The sensors can be powered by tiny solar cells, communicating in a secure wireless mesh, thereby eliminating the need for costly low-voltage wiring when retrofiting a building.
