Properly designed classroom lighting controls can reduce lighting and HVAC use by 50%.

Recent sudies have also shown that properly designed energy efficient schools and classrooms may represent a zero increase in construction costs.

Photocontrol System Field Study Final Report
Submitted by:
HESCHONG MAHONE GROUP, INC.

This study represents a milestone in the proper use of daylight harvesting for top lit applications. This information is useful not only to classrooms but also for any applications with skylights, including gymnasiums.

"Surveys of skylighted buildings in the field show that the majority of photocontrol systems that fail to achieve desired performance goals do so because of installation and commissioning problems."

"It is critical for a good installation that ... the commissioning process includes onsite adjustments for a specific time period to ensure long-term applicability. Rarely do the initial setpoints and deadbands satisfy users needs completely."

LC&D may be the only manufacturer to offer free lifetime remote adjustment of photocells.

Also from the Field Study came another important finding:

"Display of control settings and results – it is essential that the user be provided a visual confirmation of the control settings by the controller. It is also desirable to have a readout on the resultant lighting energy savings. This may be achieved in a variety of ways including but not limited to a digital readout of the sensor reading, the wattage consumed by the lighting system, and the setpoints and deadband settings."

LC&D offers the award-winning Lumen Maintenance Photocell which offers an onboard display for easy-to-set localized daylight harvesting.
