Connected lighting currently comprises less than one percent of all luminaires in the United States, but the Department of Energy (DOE) estimates that it can provide up to one quad of energy savings by 2035. And, by 2035, just under a third of installed luminaires in commercial buildings are expected to have network connectivity.
In an update and expansion to the 2017 Networked Lighting Control (NLC) data collection and analysis project (also known as the 2017 NLC Savings Study), this report from NEEA and Design Lights Consortium (DLC) expands the project sample size, increases the representation of NLC systems with Luminaire Level Lighting Controls (LLLC), provides a separate analysis for savings achieved by systems with LLLC, and increases building-type diversity.
Overall, this research project collected, aggregated, and analyzed building-, zone- and fixture-level energy monitoring interval data from NLC systems, including those with and without LLLC, in 194 buildings across a variety of building types in North America, resulting in an overview of site-specific energy savings potential.
