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

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.
