Dr. Michael S. Mott, The University of Mississippi; Daniel Robinson, University of Texas at Arlington; Regan Morse, The University of Mississippi; and Lauren Saltzman, The University of Mississippi Virtual MondayMarch 6, 20239:30am – 10:30am EST IntroductoryCredits n/a Prior research has revealed positive learning effects when students experience bright lighting with specifications set at cooler color temperatures utilizing blue wavelength and higher luminosity. Studies have found improvements for overall learning (Davis & Wilkerson, 2017); test scores (Choi & Suk, 2016); and oral reading fluency (Mott & Robinson, 2012; Mott et al., 2014). Despite these positive effects, such emphases on blue spectral wavelength coupled with high brightness as measured in lux lack visual and non-visual positive responses when compared to lighting with warmer color temperature and less luminosity. Thus, when specifications are set too cool and bright it is not as affectively appealing as warmer red wave length infused light. However, when […]

Ellie Motevalian, P2S, and Toranj Noroozi, P2S WednesdayMarch 8, 20231:00pm – 2:00pm EST Room Location: Gramercy IntermediateCredit: 1 LU / Elective This presentation addresses the current issues regarding color-changing lighting calculations and measurement methods. In recent years, the use of color-changing fixtures has been widespread in architectural lighting, yet no standardized evaluation method calculates the color-changing light attributes. The current photometric calculation tools fail to provide adequate information, and mockups are still the only way to compare RGB light fixtures accurately. In this presentation, we will share our conversation with various manufacturers, the concerns involved from the specifier’s point of view, and provide suggestions as to how the manufacturers can help specifiers to resolve these shortcomings. Basic knowledge of color changing and lighting calculation are recommended for this session. SPEAKERS Ellie MotevalianLighting Designer, P2S Ellie has a master’s degree in Building Science and Architecture. She has over 12 years of

Raymond Reyes, OLEDWorks TuesdayMarch 7, 202311:00am – 12:00pm EST Room Location: Gramercy IntroductoryCredit: 1 LU / Elective Organic light emitting diode (OLED) technology offers clear advantages for integration of lighting into products and surroundings. The unique, ultra-thin form factor combined with highly uniform illumination make OLEDs ideal for embedded applications where space is a premium and lighting is viewed directly by the user. When combined with the intrinsic high-contrast segmentation capability, OLEDs bring communication through lighting to the next level, allowing for branding and messaging on a more granular level. In this talk, we will explore the advantages OLEDs offer across current and emerging embedded product markets, including aerospace, rail, automotive, agriculture, furniture, and healthcare. Knowledge in general lighting and solid-state lighting technologies is helpful for this session. Learning Objectives SPEAKERS Raymond ReyesUser Experience Consultant, OLEDWorks Raymond Reyes earned his Bachelor of Engineering (BE) degree in Mechanical Engineering from Stevens

Dr. Mark Duffy, MD35 Consulting, Michael Davidson, Synapse Wireless, and Landon Miles, Inventronics USA TuesdayMarch 7, 202311:00am – 12:30pm EST Room Location: Murray Hill IntroductoryCredits: 1.5 LU / Elective The emergence of digital lighting systems in North America drives a recognized need for interoperable components and calls for standardized interfaces. The Zhaga Consortium creates interface specifications for components of LED luminaires that enable interoperable products supporting smart cities and buildings. The DALI Alliance creates standards like D4i for controlling and powering intelligent, IoT-ready luminaires. Combining Zhaga and D4i gives the lighting world plug-and-play options. Digital communication within lighting systems brings improved performance and expanded capabilities, such as connection to external communication systems. This seminar explains how Zhaga-D4i products improve system performance and explores new capabilities supporting designers and specifiers. Learning Objectives SPEAKERS Dr. Mark DuffyFounder, MD35 Consulting Mark Duffy serves as the General Assembly Chair for the Zhaga Consortium. Mark

Alexandra Gadawski, HMFH Architects; Jaime McGavin, HMFH Architects; Christoph Reinhart, Solemma and Massachusetts Institute of Technology WednesdayMarch 8, 20231:00pm – 2:30pm EST Room Location: Murray Hill IntermediateCredits: 1.5 LU / HSW Designers need to carefully consider how to integrate artificial and natural lighting in ways that support the larger sustainability and design goals of a project and increase occupant wellbeing. A standardized workflow can support the achievement of these goals. The session will cover a design workflow that holistically incorporates sustainable lighting design. All projects should begin by identifying the design, educational and sustainability goals of the building users and the community. A public school case study will outline a goals setting framework, and demonstrate how this workflow can be put into practice. Participants should have knowledge of terminology and metrics associated with lighting design. Learning Objectives SPEAKERS Alexandra GadawskiAssociate, HMFH Architects Alexandra Gadawski WELL AP, LEED AP BD+C is

Leela Shanker, Borealis Lighting Studio & GreenLight Alliance LCA Incubator; Russell Greenberg, Rux Studio; and Kate Hickcox, Pacific Northwest National Laboratory WednesdayMarch 8, 202311:00am – 12:30pm EST Room Location: Murray Hill IntermediateCredits: 1.5 LU / HSW The need for a consistent, comparable approach to Life Cycle Assessment (LCA) of luminaires and spatial lighting strategies has been widely accepted by the lighting industry. Current industry and government initiatives are enabling informed decision making and providing greater certainty in comparing material, production and experiential design choices. Sharing initial findings from the PNNL LCA Project and LCA Incubator of the GreenLight Alliance and IALD LIRC, this session will update manufacturers on the reality of collecting and processing data for LCAs, and designers on how to value and interpret the resulting criteria published in Industry and Product Specific Environmental Product Declarations. Recommended: Understanding of basic lighting principles and industry stakeholders assumed. Awareness of lighting

Parisa Mahmoudzadeh, Pennsylvania State University; Wenye Hu, University of Sydney; Wendy Davis, University of Sydney; and Dorukalp Durmus, Pennsylvania State University TuesdayMarch 7, 20239:00am – 10:30am EST Room Location: Murray Hill IntermediateCredits: 1.5 LU / Elective Lighting application efficacy (LAE) is a novel measure of the holistic usefulness of lighting in buildings. In comparison to individual product efficiency (luminous efficacy), LAE can quantify the proportion of light that actually reach occupants’ eyes as a function of consumed power. Our proposed three-tier LAE framework accounts for luminaire efficiency, spatial efficiency, and visual sensitivity using ray-tracing software and data from visual studies. Our calculation tools and step-by-step guidelines will enable designers and manufacturers to assess lighting design solutions and characterize the energy performance of lighting systems, including smart lighting systems.
