Paper accepted to the ACEEE Summer Study on Energy Efficiency in Buildings

A paper co-authored by Siobhan Rockcastle (Baker), Megan Danell (Baker), Lisa Petterson (SRG Partnership), and Maria Ámundadóttir (OCULIGHT analytics) has been accepted for oral presentation at the ACEEE Summer Study on Energy Efficiency on Buildings. This paper, titled ‘The Impact of Behavior on Healthy Circadian Light Exposure Under Daylight and Electric Lighting Scenarios,’ presents a simulation-based method to compare the healthy light exposure of dynamic spatial and temporal occupant profiles using surveyed data.

Baker researchers go Virtual with a grant from PNNL

Researchers from the Baker Lighting Lab will compare the perceptual accuracy of LED lighting environments using a range of industry leading VR HMDs. In a time of physical separation from the world around us, our team of student and faculty researchers will explore differences in visual perception between the screens that define our virtual frontier. This work is supported by the generous support of a grant from the Pacific Northwest National Laboratory.

paper co-authored by Danell and Rockcastle accepted to SimAUD 2020

A collaborative paper, ‘Evaluating temporal and spatial light exposure profiles for typical building occupants,’ co-authored by Megan Danell and Siobhan Rockcastle from Baker Lighting Lab and Maria Amundadottir from Oculight analytics was just accepted to SimAUD 2020 in Austria.  Thanks to the support of Lisa Petterson at SRG partnership in Portland, our team was able to simulate occupant profiles in a digital model of SRG’s office space and compare their circadian health in a new temporally and spatially-resolved simulation workflow.

Megan Danell (M.Arch ’20) will present this paper to an international audience in May!

Zach Suchara, Director of Luma Lighting to Lecture in Eugene on November 7th

Zach Suchara will give a guest lecture in IARC 492/592 Electric Lighting on November 7th at 6:oopm in LA206.  This lecture is open to the public and anyone interested is welcome to join!

Zach’s Bio:  Zach joined Luma in 2006 and oversees the management, development, and growth of the firm. He has extensive experience with projects throughout the Pacific Northwest and California, and beyond—Luma’s experience currently extends across the U.S. and into Asia and central Europe. As a registered architect in the state of Oregon with over 20 years of experience in architecture and lighting design, Zach strives to continually reinforce humanistic integration with the natural and built environment. For him, light is more than a medium to apply to architecture. It is a foundational component for shaping human experience. Zach’s passion for holistic, sustainable, and humanistic design integration is evidenced by his diverse, award-winning project work, national and international speaking engagements, and participation in multiple industry organizations such as the AIA, IES and AFO. 

Dr. Rockcastle and Dr. Van Den Wymelenberg to Present ‘Current Trends in Daylighting’ at PG&E on November 14th

Kevin Van Den Wymelenberg and Siobhan Rockcastle from the University of Oregon’s Institute for Health in the Built Environment and Baker Lighting Laboratory will discuss why we should still consider controlled daylight an essential part of high performance and occupant supportive building design. The instructors will address daylight’s role in improving health, well-being, productivity, and energy-efficiency, even as LEDs and on-site photovoltaic electric generation converge to seemingly erode the business case for daylighting.

University of Oregon Publishes White Paper on Light, Views, and the Workplace Experience

The white paper, “The Impact of Lighting and Views in the Workplace of the Future,” explores how light and the visual environment impact performance, comfort, and satisfaction of the occupant

Eugene, OR (August 12, 2019) – Today, the University of Oregon published a new white paper, “The Impact of Lighting and Views in the Workplace of the Future.” The paper concludes that daylit spaces with controlled lighting and views can improve occupant well-being, workplace productivity, and satisfaction by positively influencing various physiological and psychological processes. Lighting and views also impact property value and employee recruitment and retention.


To learn more about the emerging evidence and our interpretation, read our whitepaper here.

“The Impact of Lighting and Views in the Workplace of the Future” white paper, which was sponsored by Lutron Electronics, was presented at the Illuminating Engineering Society Annual Conference in Louisville, August 2019.


Earn $25 as a participant in our study on lighting perception!

The University of Oregon Baker Lighting Lab is currently seeking subjects for a research study on lighting perception which compares physical spaces to immersive photographs displayed on various digital devices, including VR. The total time commitment will be about 30 minutes and will require the participant to sign up for and attend a single session. Compensation of $25 will be distributed at the time of the participant session. Participation is entirely voluntary.

Location:  University of Oregon, Eugene campus

Eligibility: Age 18+, English Fluency Required

Disqualifying Conditions: Visual impairment (partial or full blindness) or Pre-existing binocular vision abnormalities

Potentially Disqualifying Conditions: Psychiatric Disorders, Heart Conditions, or Other Serious Medical Conditions

Potential Risks: The physiological and psychological risks associated with this experiment are determined as minimal. All experimental conditions that participants would be exposed to could be experienced in a classroom setting under commercially available lighting products or on a commercially available display device. Participants might feel slight visual discomfort according to lighting preferences, glare levels, and luminance levels presented by the displays. While very rare, some people may experience seizures while wearing a Virtual Reality Headset.  If you are assigned to the VR group and have any of the potentially disqualifying conditions, you may be dismissed from the experiment or reassigned to a different group.

Confidentiality: Your identity will be kept strictly confidential and will only be used for scheduling and informed consent purposes. Your identity will not be stored in the dataset and will not be revealed in any published information produced by the experiment.

Baker Lighting Lab secures grant from PNNL to study Virtual Lighting Perception

Baker Lighting Lab, under the supervision of Assistant Professor Siobhan Rockcastle, has secured a grant from the Pacific Northwest National Laboratory (PNNL) to study the perceptual accuracy of solid state lighting in an array of virtual displays, including HDR and VR screens.  This research will include a pilot study on the U of O campus this summer.  Please contact us if you’re interested in learning more about this project.

Paper on occupant-centric daylight analytics accepted to Building Simulation 2019 in Rome

A peer-reviewed paper, titled “The case for occupant-centric daylight analytics: a comparison of horizontal illumination and immersive view” had been accepted to the proceedings for Building Simulation 2019 in Rome.  Siobhan Rockcastle co-authored this paper with Marilyne Andersen from the EPFL in Switzerland and Maria Amundadottir from OCULIGHT analytics in Iceland.
