Shaun Fillion provides an under-the-hood look at radiosity calculations and raytrace renderings. We take look at the methodology used by photometric calculation software to represent the performance of lighting in the built environment, tracking it from the roots of the Lumen Method and Inverse Square Law. Visual representations of illuminance versus luminance are also covered. The seminar also diagnoses and tweaks example models to make the lighting calculations more accurate. Read more

In 2008 the IES published LM-79, “Approved Method: Electrical and Photometric Measurements of Solid-State Lighting Products.” This measurement standard for solid-state lighting products quickly became the world recognized standard for measuring LED lighting products. In 2019 the IES Test Procedures Committee (TPC) completed a comprehensive review and revision of LM-79. The revision was published as ANSI/IES LM-79, “Approved Method: Optical and Electrical Measurements of Solid-State Lighting Products.” The revision includes better guidance on how to make measurement and requirements that help to reduce measurement variations between different testing facilities. Consideration for these changes was based on information collected from NVLAP proficiency testing, independent research, and an effort to help minimize the burden on testing laboratories. Join us for our first educational session on LM-79 since the revision was published, and learn from experts in this topic Cameron Miller and Eric Bretschneider. Read more

In this webinar, presenters will discuss the challenges with configuration, commissioning, and maintaining control settings over time have slowed progress towards integrated lighting and building system controls. Overcoming such challenges can enable energy savings, adaptive lighting for occupant alertness and wellbeing, and better space management in buildings. This webinar will explore some practical solutions to address controls complexity, including development of a clear and concise sequence of operations, the use of controls narratives, and online tools and templates to make these solutions more accessible.
