Memo: Clarifications to the 2020 Report: “Energy Savings from Networked Lighting Control (NLC) Systems With and Without LLLC”
This memo provides clarity on interpreting the presented information and further elaborates on key points in the 2020 Savings Report.
Key Takeaways
- The control savings factors (CSFs) in the 2020 report represent average savings across a diverse set of projects, which include both optimally and sub-optimally programmed systems. Energy efficiency programs that implement mechanisms to specify or verify proper NLC system programming can expect higher savings, as CSFs are influenced by system setup and optimization.
- High-end trim and other control strategies deliver distinct savings. While high-end trim reduces the lighting load first, other strategies save energy from the remaining load. To maximize savings, EE programs can incentivize and measure these strategies separately, using the CSFs provided in the updated report for independent assessment.
Seven Strategies to Minimize Negative Impacts of Outdoor Light at Night
This resource provides high-level application strategies that go beyond the LUNA product requirements for energy efficiency program staff, contractors, distributors, and lighting practitioners who are interested in using outdoor lighting that is both energy efficient and reduces light pollution.
Key Takeaways
- Overview of the types of light pollution that affect outdoor environments.
- High-level information for energy efficiency program staff, contractors, distributors, and lighting practitioners on outdoor lighting application strategies beyond the DLC LUNA product requirements.
Key Takeaways
- NLC integrated with HVAC can save 30% of the HVAC load through occupancy control, at a small fraction of the cost of HVAC replacement.
- Incentives for uncontrolled LED lights destroy opportunities for these deep, cost-effective energy savings, because each new LED locks out these opportunities over the 10+ year product lifetime.

Executive Summary: Choosing Both Energy Efficiency and Light Pollution Mitigation for Commercial Outdoor Lighting
There is a perception that, in a commercial retrofit setting, light pollution mitigating LEDs are less efficient and more costly than energy efficient LEDs, but in some cases you can have the best of both worlds. The DLC commissioned a study to research the impacts of LED applications that are both energy efficient and minimize light pollution as compared with products focused solely on energy efficiency. This executive summary provides an overview of the results of the research.
Key Takeaways
- An overview of how utilities can help municipalities achieve their energy efficiency and decarbonization targets while protecting ecosystems and preserving the night sky for future generations.
Choosing Both Energy Efficiency and Light Pollution Mitigation for Commercial Outdoor Lighting
There is a perception that, in a commercial retrofit setting, light pollution mitigating LEDs are less efficient and more costly than energy efficient LEDs, but in some cases you can have the best of both worlds. The DLC commissioned a study to research the impacts of LED applications that are both energy efficient and minimize light pollution as compared with products focused solely on energy efficiency. The study includes analysis of the impact on ROI, annual energy use, and energy costs.
Key Takeaways
- Learn how utilities can help municipalities achieve their energy efficiency and decarbonization targets while protecting ecosystems and preserving the night sky for future generations.
- Discover how municipalities can meet their energy goals while reducing the harm caused by excessive outdoor lighting.
- Learn new ways to calculate ROI for responsible outdoor lighting.
