Industry Reports and Research
Future-Proofing Energy Efficiency with Networked Lighting Controls
This is a summary of the potential study commissioned by the DLC titled "Economic Potential of Networked Lighting Controls in Commercial Buildings: Tapping the Added Value of HVAC Connections."
Key Takeaways
- Learn how integrating HVAC and NLC systems can enhance energy efficiency, increase ratepayer savings, and lower carbon emissions.
- Action items for regulators and energy efficiency programs based on the new data.
Evaluating the Non-Energy Benefits of Advanced Networked Lighting Controls
This resource, which summarizes research commissioned by the DLC and conducted by Skumatz Economic Research Associates, Inc. (SERA), identifies non-energy benefits (NEBs) specific to NLC usage and develops a methodology for assigning them quantitative values.
Key Takeaways
- “Non-energy benefits” of NLCs can enable inclusion of anticipated savings from productivity gains, safety and security enhancements, extended equipment lifecycles, and more in cost-benefit calculations.
- Developing a methodology for assigning quantitative values to NEBs will enable utility incentive program staff and others to use an expanded set of metrics for measuring the cost-effectiveness of NLC implementation.
- Research showed statistically significant non-energy benefits from NLCs for both lighting decision makers and building occupants.
Journal Article: Specifying non-white light sources in outdoor applications to reduce light pollution
This journal article, originally published in Leukos on January 5, 2023, proposes a specification structure for amber light sources to increase the precision of language used in the industry, and encourages lighting standards development organizations to consider standardizing such a system. It also demonstrates that non-white light sources with well-defined chromaticity ranges outside of the ANSI C78.377-2017 quadrangles may be useful for reducing wasted light that causes sky glow, a phenomenon that is associated with approximately $7 billion in wasted energy and nearly 66 million metric tons of CO2 emissions annually.
Key Takeaways
- A call for the lighting industry to consider developing industry consensus definitions and standards for “amber" light sources.
- Methodology for expanding ANSI standard CCT chromaticity bins to include three new bins: 1800K, 2000K, and PC Amber.
- Discussion of why CCT alone is not an adequate representation of the spectral composition of light, and the wide range of potential impacts to sky glow.
Outdoor Lighting Ordinances
The DLC conducted research to identify locations with published outdoor lighting ordinances to mitigate light pollution. Check the map to see if you have an outdoor lighting ordinance in your area.
Key Takeaways
- Learn more about what an outdoor lighting ordinance is
- Check the map to see if you have an outdoor lighting ordinance in your area
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.
Whitepaper: Proposed Revisions to DLC Energy Reporting Requirements
This whitepaper describes various proposals to make DLC requirements and recommendations for energy reporting more useful to a broader audience. The proposals are based on the new ANSI standards and on input from a working group convened in Q4 2021 comprised of representatives from DLC member efficiency programs and DLC industry partners.
Key Takeaways
- Energy efficiency programs have varying requirements for energy reporting, creating burden for manufacturers to create a unique reporting function for each program.
- This whitepaper describes various proposals to make DLC requirements and recommendations for energy reporting more useful to a broader audience.
- These proposed changes are being made available in advance of a public comment period so that stakeholders can consider implementation and prepare accordingly.
