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.
Navigating the DLC QPL: Family Grouping and Product Data
This guide explores the types of product data available on the DLC SSL QPL, how products are grouped into families, and the distinction between parent and child products.
Key Takeaways
- Describes the different types of product data available on the SSL QPL.
- Explains the difference between parent and child products.
- Explains the rationale for testing and reporting requirements for product families.
Outdoor Lighting Ordinances Map Data
Download the data from our outdoor lighting ordinances map. Last updated in June 2024.
Key Takeaways
- Outdoor Lighting Ordinances for Mitigating Light Pollution in the US and Canada
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.
Lighting Controls Best Practices
This resource explains the following basic networked lighting control strategies: dimming, high end trim, occupancy/vacancy sensing, scheduling, and daylight harvesting, and gives an overview of how to implement them to maximize energy savings.
Key Takeaways
- Describes five basic networked lighting control strategies: dimming, high end trim, occupancy/vacancy sensing, scheduling, and daylight harvesting.
- Explains how to apply each strategy effectively to maximize energy savings.
