The Illuminating Engineering Society (IES) recently published ANSI/IES LP-10-26, Lighting Practice: Lighting for Sustainability, the culmination of nearly six years of work by the IES Sustainable Lighting Committee. SFIL Associate and Sustainability Leader, Melissa Mattes has served as Co-Chair throughout the development of the new edition, helping lead a complete rewrite of the previous 2020 document from initial research and content development through the formal ANSI/IES consensus and publication process.
A major evolution in LP-10-26 is its broader definition of sustainable lighting. While the previous edition focused heavily on environmental impacts, energy and carbon, the new document takes a more holistic approach, considering the visual needs of people alongside equitable benefits to society and the environment. The LP-10-26 explores sustainability at multiple scales, from individual lighting products and material choices to design practice, manufacturing, and broader business operations.
The new edition also significantly expands its treatment of the lighting life cycle, examining impacts associated with materiality, production, transportation, installation, operation, maintenance and end-of-life. Additional sections address material health, product transparency, circular-economy principles, rating systems, corporate responsibility, and social and environmental justice.
The final two years of this process involved a formal ANSI/IES review, including multiple public-review periods, comment resolution, revisions and consensus-building, as well as repeated coordination with the National Electrical Manufacturers Association (NEMA). Following this extensive review, the document was finalized and published as an IES technical lighting practice standard.
Melissa and fellow Co-Chair Alexandra Christiana recently highlighted the completed work at IES26: The Lighting Conference in Denver, presenting LP-10: Lighting for Sustainability: Overview and Action and helping practitioners understand how the new guidance can be applied in practice. Prior to the start of the conference, the Edison Report singled out the presentation as one every lighting professional should attend, noting that “the LP-10 has the potential to become one of the (IES’s) most influential documents in the coming years.”
Melissa’s leadership on LP-10 reflects Sladen Feinstein’s commitment not only to implementing sustainable practices within our projects, but to helping shape how sustainability is understood and advanced across the lighting industry.
