The Northwest Energy Efficiency Alliance (NEEA) contracted with Cadeo Group to estimate the current potential market size for exterior luminaire level lighting controls (LLLC) in non-residential parking in the Northwest, as NEEA considers including this application in the program. Cadeo Group reviewed secondary data sources to understand the current market size for this application and estimate how the potential might change over time.
Findings indicate that the current number of exterior luminaires in Northwest parking lots is within the range of 860,000 to 3.5 million luminaires, however more research is needed to refine the values further. Additionally, report findings determined that less than 1% of total existing luminaires in Northwest parking lots currently have LLLC installed. Most open-air parking lots are suitable applications for LLLC systems and may benefit from both energy savings and security improvements. Finally, report findings forecast that the total square foot coverage of parking lots in the Northwest will increase by approximately 3% over the next 20 years. This projected expansion of parking infrastructure indicates a similar growth pattern in exterior luminaires, and therefore a modest growth in the opportunity for LLLC systems in the region.
