The new testing facility will provide the information necessary to overcome one of the major barriers to the growth of mass timber: acoustics performance. Mass products are growing in popularity as an innovative building material, particularly in multifamily residential dwellings for which they are structurally well-suited. However, these products’ ability to reduce floor-to-ceiling noise transfer has not been tested. Locally sourced testing of mass timber materials would give building owners, contractors, building code officials, and design and engineering professionals the confidence needed to demonstrate that these products are cost-effective and meet performance requirements.
Currently, the only way to test acoustics performance is to ship samples to testing facilities on the East Coast. This drastically increases project costs and construction schedule. Constructing an acoustic testing facility in Oregon will allow the mass timber industry to become a hub for both the development and production of mass timber products for the US and internationally.
While mass timber is the driving force behind the proposal to acquire this facility, multiple other traded sectors and industries in Oregon and across the Northwest would benefit from the facility, including aviation, other buildings material manufacturers such as glazing and curtain walls, façade cladding, masonry, and straw bale.

ESBL and BioBE are thrilled to announce that Dr. Siobhan “Shevy” Rockcastle has joined the team as a new Assistant Professor of Architecture, and Chair of the Baker Lighting Lab, in the Department of Architecture on the main University of Oregon campus in Eugene. She will be adding her expertise in architectural design, human perception, environmental dynamics, and building performance with a focus on occupant well-being, particularly with lighting. Dr. Rockcastle’s current research uses virtual reality to map human responses to daylight and composition in immersive architectural environments.
In addition, she is studying the impacts of climate on perception, emotion, and comfort in architecture; the use of virtual reality to study subjective, behavioral, and physiological responses to space; the impacts of light exposure on human health through hormonal responses in the brain; and impacts of sunlight composition on perceptual evaluations of architecture. Students interested in any of these topics are encouraged to contact Dr. Rockcastle to learn about current research opportunities.
Shevy earned her professional BArch from Cornell University in 2008 and her SMArchS degree in Building Technology from MIT in 2011. She has taught design studio and seminar courses in environmental systems at Cornell University, Northeastern, MIT, and EPFL. Her professional work experience includes KVA matX, Snøhetta, MSR, Epiphyte lab, and Gensler. As a continuation of her thesis at MIT, Siobhan’s PhD dissertation used experiments to measure the impacts of daylight and spatial composition on perceptual responses to architecture and proposed simulation-based algorithms to predict these responses under varied climatic conditions. She has published numerous peer-reviewed journal and conference articles on this work and combines scientific publication with applied creative practice.
She is also a co-founder of OCULIGHT dynamics, a Swiss company offering daylight design support through custom simulation-based tools.

How do you illustrate the microbiome of bacterial, fungal and viral communities to architects, engineers and building equipment manufacturers? You commission an artist! During the events of Health and Energy Research Consortium, Morgan Maiolie was busy with a brush set to canvas. Associate Professor, and director Van Den Wymelenberg notes “We really wanted to find a way to bring the microbiome to life for the diverse consortium guests, so we decided to invite an artist to complete a live painting that responded to the research presentations. Morgan Maiolie did an excellent job understanding and translating our scientific findings into her painting. She made the microbiome vibrant and tangible!”
Morgan describes her inspiration, “The team of research scientists at the Biology and Built Environment Center and Energy Studies in Buildings Laboratory have illuminated the world of living, breathing bacteria swirling in the air around us and this piece visualizes that invisible world. The researchers made me aware of the key role building design plays in shaping our indoor microbiome. Buildings can act as filters, petri dishes, and wind tunnels. I wanted the painting to conceptually reveal how bacteria might move into and through a building based on its architecture, systems, and inhabitation.”

Humans spend most of their time indoors, exposed to bacterial communities found in dust. Understanding what determines the structure of these communities may therefore have relevance for human health. Light exposure in particular is a critical building design consideration and is known to alter growth and mortality rates of many bacterial populations, but the effects of light on the structure of entire dust communities are unclear.
We performed a controlled microcosm experiment designed to parse the effects of filtered solar radiation on the structure of dust microbial communities.
We report that exposure to light per se has marked effects on community diversity, composition and viability, while variation in light dosage or particular wavelengths experienced are associated with nuanced changes in community structure. Our results suggest that architects and lighting professionals designing rooms with more or less access to daylight may play a role in shaping bacterial communities associated with indoor dust.
Judith Sheine, University of Oregon Professor and Head of the Department of Architecture, and Iain Macdonald, Associate Director of the TallWood Design Institute, introduced their approach to healthy and efficient mass timber buildings: the TallWood Design Institute. This joint initiative of OSU’s Colleges of Forestry and Engineering and UO’s School of Architecture & Allied Arts seeks to promote the use of innovative wood products and building components produced in the state of Oregon.
The Institute’s mission is to increase the ability of Oregon’s manufactured wood products industries to compete in emerging markets for the high value wood products that are perfectly suited to the timber we grow and the stewardship ethic of our State and to support Oregon’s growing reputation as a center of expertise for sustainable building design. We are working to grow the mass timber manufacturing base in Oregon and to eliminate barriers and stimulate demand for buildings utilizing mass timber products and building systems.
With funding from the state and federal governments, we have currently underway $1.9 million in mass timber research projects on seismic and fire resistant performance, vibration, acoustic and energy characteristics, as well as life cycle and biome analysis. We are performing testing and peer review of mass timber structural components and systems to prototype and refine new products and partnering with product manufacturers and state building officials to allow these products and systems to be permitted for construction. The Institute is also providing educational programs at the two universities as well as workforce training and engaging in the design of demonstration projects in Oregon.
One of the key topics discussed at the Health Energy Research Consortium was natural daylight and its relevance to healthy living and working environments. Amir Nezamdoost, UO architecture PhD and ESBL graduate research fellow, presented his current research on overlit spaces and the human factor associated with blinds operation.
Daylighting is a common energy-efficiency strategy that also boasts a myriad of other human benefits (Reinhart & Selkowitz, 2006; Van Den Wymelenberg, 2014). Successful daylighting design that saves energy and improves human satisfaction incorporates many technologies, spans several disciplines, and requires attention throughout the design process. Blinds are quite common in spaces designed for daylighting (HMG PIER Review, 2012; Nezamdoost & Van Den Wymelenberg, 2016, 2017), since almost any daylighting design will bring with it some period of low angle sunlight, causing intermittent glare and requiring mitigation.
Moreover, with the latest published version LEED (v4), a greater emphasis is now being placed on implementation of glare control devices in buildings to protect occupants from sunlight exposure and subsequent glare and thermal stress.
Blind position and operation affect the amount and distribution of daylight entering a building as well as all forms of thermal transfer through windows. Daylight-sensing lighting control holds the potential to save significant energy, however, realized savings are reduced if window blinds are closed. Blinds have the potential to reduce cooling energy and peak cooling demand, especially if located outside of the thermal envelope. Effective daylight-sensing lighting controls can also reduce cooling loads by minimizing waste heat from lights. However, these potential impacts cannot be determined without accurate manual blind models.
Recent studies conducted by Nezamdoost and Van Den Wymelenberg, show that current manual blind use candidates are too active and behave like an automated shading system. Overall, in order to develop a reliable manual blind use pattern for future use in simulation broadly, and energy codes, and daylighting standards specifically, additional human factors and post occupancy research of manual blind use in real buildings is needed.

Dristi Manandhar is a second-year graduate architecture student at University of Oregon who has been working at the Energy Studies in Buildings Laboratory. But her inspiring story goes far beyond her experiences in the classroom.
On April 25, 2015, Manandhar was with her family at home in Kathmandu, Nepal when a 7.8 magnitude earthquake struck. Manandhar was fortunate to lead her parents and younger sister to safety outside. The earthquake resulted in more than 8,000 dead, 21,000 injured, 40 percent of the country’s infrastructure damaged and nearly 505,000 homes destroyed. Manandhar was fortunate to remain safe with her family and see her home only moderately damaged, despite the disastrous effects of the earthquake.
In response to the devastation around her, Manandhar joined the Nepal Engineering Association to assess more than 300 homes’ safety and structural integrity. Dismayed by how helpless she felt telling people that their homes were no longer safe, Manandhar changed her approach. She and six architecture alumni from her university joined forces to design an emergency shelter, using the name Aashraya, Sanskrit for shelter.
The team quickly designed with a dome-like shelter inspired by Eli Kretzmann’s Pakistan flood relief shelters. Aashraya shared the plans and was able to help create over 2,300 shelters in 45 days across Nepal. The domes are both economical and resilient to Nepal’s harsh weather conditions.
At University of Oregon, Manandhar has become the first Nepal Scholarship recipient and a member of the International Cultural Service Program, an international student group that connects students from around the world with community events and engagement opportunities. As a graduate architecture student, she has been researching sustainable design, particularly passive heating and cooling methods in buildings at the Energy Studies in Buildings Laboratory.
After the past two years away, Manandhar will graduate from the UO in Spring 2017 and plans to return home to pick up where she left off.
