The Northwest Energy Efficiency Alliance (NEEA) contracted with Energy Solutions to estimate the additional equipment and labor cost to install Luminaire Level Lighting Controls (LLLC) compared to other options. The outcome of this annual study, conducted since 2017, enables NEEA to track cost trends and conduct cost-effectiveness analysis.
The research team interviewed a total of 16 manufacturers and manufacturer representatives to collect detailed labor and other cost data across 19 lighting projects based on prototypical office buildings.
The study found that:
- In 2020, the cost on a per-fixture basis of the most basic LLLC luminaire was $149, compared to $100 for a standard LED fixture without controls.
- Between 2017 and 2020, the per-fixture incremental cost of the most basic LLLC fell 28%.
- Over the same period, the per-fixture incremental cost of an LLLC fixture luminaire with added features such as asset tracking fell 16%.
