Groom Energy Intelligent LED Lighting Upgrade Project Wins 2011 Lighting Control Innovation Award Of Merit

04/30/2012 by Lighting Controls Association 1 Comment

The Lighting Control Innovation Award was created in 2011 as part of the Illuminating Engineering Society’s Illumination Awards program, which recognizes professionalism, ingenuity and originality in lighting design. LCA is proud to sponsor the Lighting Control Innovation Award, which recognizes projects that exemplify the effective use of lighting controls in nonresidential applications. In this award’s first year, eight projects were recognized with an Award of Merit, with one further recognized with a Special Citation Award.

This month, we will explore the role that sophisticated lighting controls play in minimizing energy costs for Groom Energy Solutions’ client Maines Food & Paper, which won an Award of Merit. Lighting design by Groom Energy Solutions. Photography by Bob Kirby. Control manufacturers/products: Digital Lumens ILE-HB-3 with Lighting Rules.

This project for Maines Food & Paper involved a lighting efficiency upgrade involving conversion from 400W HID to 160W intelligent LED lighting.

The above image shows the “before” condition. Requirements included improving light levels and reducing energy use fulfilled by introducing intelligent system with integrated sensors, computer and wireless networking.

The above image shows the “after” condition. The lighting management software provides reporting of fixture-based energy and occupancy data, as well as control of fixtures in zones with active and inactive full-range dimming and occupancy sensor time delays (as low as 30 seconds).

The lighting management software provides communication with all fixtures in the facility via the wireless mesh network. The system operates according to zone-based settings given to it by the software, which can be adjusted at any time. Reporting of Occupancy and Energy data allows verification of energy savings as well as fine-tuning of the facilities lighting system over time to maximize energy system and manage the asset.

Zone-based control of fixture settings with active and inactive levels and sensor delays. Fixtures programmed with these settings via wireless control, and operates independently of other fixtures according to these rules. Continuously able to maximize energy efficiency.

Row of lights operating in the same zone. Set with an inactive dimming level of 10%, so some light level is available even when the area is not occupied.

After an occupant has passed through the aisle triggering each fixture’s occupancy sensor and the active dimming level of 100%. Each fixture in this zone returns to inactive dimming level of 10% after only 90 seconds, providing light efficiently when needed.

100% output.

Each fixture in this zone returns to an inactive dimming level of 0% after only 60 seconds since last detecting occupancy.

94% reduction in lighting run hours and a 87% reduction in lighting energy

Energy Efficiency: 0.575W/sq.ft. lighting power density before, 0.24W/sq.ft. after. Budget: ROI was calculated at 210%.
