Product breakthrough: Self-commissioning digital photosensor

The LRC has developed an easy-to-install and easy-to-use photosensor unit that promises greater acceptance by end users. With the press of a single button, the photosensor automatically adjusts its settings for maximum energy savings while maintaining appropriate electric light levels.

LRC researcher Andrew Bierman (shown in photo) developed the photosensor. Bierman says the adaptable control algorithm is suitable for a wide range of room types and light distributions. Light level preference is separate from commissioning, allowing occupant adjustment without affecting commissioning set points. The sensor is wireless for easy placement.

Typically, many people are unhappy with automatic lighting controls, so they "decommission" them by placing tape over the sensors or disconnecting them. Their energy-saving potential is then lost. This easy-to-use unit encourages greater acceptance by end users.
