Pacific Northwest National Laboratory (PNNL) has published findings from a DOE-funded study conducted to estimate the energy savings opportunity associated with advanced lighting research related to glare, flicker, color rendering, non-visual effects of lighting, and outdoor environmental effects of lighting.
Part one of the study, conducted by Skumatz Economic Research Associates (SERA), estimated the buyer value of advanced lamps and luminaires in three lighting product categories: commercial 4-ft linear LED luminaires, residential general service LED lamps and street/roadway luminaires. These products were selected as representatives of the larger market sectors from which they were drawn (commercial, residential and outdoor).
Part two of the study, conducted by Guidehouse Consulting, applied the SERA estimates of value as inputs to the lighting market model used by DOE to estimate future energy savings from advanced lamps and luminaires. The model translated SERA’s findings into estimates of energy saving opportunity. Key findings include:
- Advanced LED products added 334 tBtu of source energy savings to projected LED energy savings in 2035. That’s an additional 31 billion kWh of electricity saved in U.S. buildings in 2035, above and beyond what LEDs are already expected to provide, and equivalent to about 10% of total lighting energy use across commercial, outdoor and residential sectors in the year 2035.
- Surveyed lighting users saw substantial value in the lighting improvements sought from planned research, with incremental long-term perceived values equivalent to 43-46% of the estimated baseline luminaire prices.
The findings also confirm that the methodology used holds promise for identifying energy-saving opportunities that may be difficult to quantify for advanced features. To learn more, download the full report.
