Technical Luncheon Presentation Archive

The IES Portland Section also offers monthly Technical Luncheon Seminars where we have an industry leader come and give a talk on a current topic. These seminars are well attended and are a great opportunity to secure continuing education credits as well as network with peers.

  •   Horticultural Lighting Research Update
    Presented by Derek Smith, Resource Innovation and Gretchen Schimelpfenig, PE, Technical Director Resource Innovation   |   November 18, 2020
    Gretchen Schimelpfenig, PE, is the Technical Director of Resource Innovation Institute (RII) and manages the organization’s educational curriculum, Technical Advisory Council, and the Cannabis PowerScore resource benchmarking platform. She has a B.S. in Architectural Engineering from the University of Wyoming and an M.S. in Civil Engineering from Stanford University. She is a licensed Civil Professional Engineer in California and Vermont. While serving Burlington Electric Department customers as an Energy Services Engineer, she incentivized horticultural LED lighting equipment through energy efficiency programs, and has commissioned LED lighting and HVAC designs and installed systems in commercial and industrial buildings, including MEP systems used in facilities conducting academic research on hemp and other cultivars. She authored the RII Best Practices Guides on HVAC and LED Lighting for Cannabis Cultivation and Controlled Environment Agriculture.

  •   Biologically Focused Lighting
    Presented by Robert Soler, VP Human Biological Research and Technology   |   January 15, 2020
    Architectural lighting is no longer just for the visual system. With growing emphasis on healthy built environments, circadian lighting is a popular topic that many designers and end-users are being asked to explore.Within the eye we each have non-visual photoreceptors which assist in regulating our circadian rhythms. Modern architectural lighting has been designed and calibrated to meet the needs of our visual system, however, it provides insufficient stimulus for the human circadian system and does not allow our bodies to properly reinforce our natural biological signals.The lack of proper circadian stimulus and the desynchronization of our activity with the solar day has been shown to lead to a state of Social Jet-lag which has been tied to many dysfunctions, such as disrupt sleep cycles.

    This seminar explores the science behind the circadian system and outlines how to integrate essential spectral content in architectural lighting that helps entrain and reinforce healthy circadian rhythms.

    Learning Objectives:

    1. Understand the basic science of circadian rhythms and its interaction with light
    2. Describe the design considerations needed for implementing circadian lighting
    3. Understand how color tuning addresses circadian lighting needs
    4. Understand how light spectrum addresses circadian lighting needs

  •   ICE and Darkness: A Circadian Story
    Presented by Martin Valentine, FSLL MIES  |  March 18, 2019
    British Antarctic Survey’s Halley VI Station is the 6th version of BAS’s permanent home that has sat on Antarctica’s Brunt Ice Shelf since 1964. Halley VI was designed in 2006 and opened in late 2011. Every April a core selection of 20 out of the base’s approximate 80 staff remain to ‘winter’ for around 100-days, isolated and in permanent nighttime until relief arrives the following spring.The Speaker was responsible for the lighting design of this space-station on ice and within the design process was able to bring in endocrinological research data gathered from the winter crew of previous Halleys spanning 40-years. Cases of psychosis, suicide, depression are all too common historically in those whom winter in Antarctica and research data was invaluable on how people are subjectively and objectively affected by these long winter periods, including recording of hormone levels, monitoring of light and UV exposure and EEG/ECG readings.This presentation shows the history and challenges of life in Antarctica, the research, analysis and the solutions for the unique energy-efficient sustainable lighting design that was installed in Halley VI. Now, over ten years since the lighting design was first conceived and five years since the station became occupied, the story and solution for Halley has resonance and lessons to give to many of us in the field of human-centric lighting.
