Luminaire-level lighting control (LLLC) has attracted significant interest among building owners and utilities as a simple path to maximize energy cost-savings from LED lighting installation. A study conducted by the University of Oregon in Eugene on behalf of the Northwest Energy Efficiency Alliance (NEEA), Portland, Ore., demonstrated that LLLC produced similarly substantial energy savings as a networked lighting control system, but at a lower cost.
The researchers discovered that all these systems produced substantial energy savings compared to the baseline. The LLLC systems generated 50%–74% energy savings for the control element alone, while the NLC redesign demonstrated 67% energy savings. Admittedly, the space was very well suited to LLLC compared to the NLC solution.
