Mill Race Make Lab Springfield, Oregon | Winter-Spring 2012 | Studio led by Brook Muller Programming, Site Analysis and Design, Schematic Design, Sustainable Cities Initiative for Springfield, OR ARCHITECTURE OF BENEFICIAL DISTURBANCE Springfield’s rich history revolves around production, and the center of the city’s productive capacity has long been the Booth-Kelly lumber mill, two blocks south of downtown. The decline of the mill since its heyday in the early 20th century has left an anonymous vacancy in the urban fabric, and has contributed to Springfield’s diminishing sense of identity. The Mill Race Make Lab is an architecture of beneficial disturbance - a catalyst that reconnects the Booth-Kelly site to downtown Springfield and to a neighboring wetland complex currently undergoing restoration. The Make Lab serves as a public gateway to the restored millrace and wetland complex, and recharges a culture of craft in Springfield and the region while honoring the culture, history and ecology of the Booth-Kelly site.

A THEATER OF PRODUCTION Comprised of a series of three buildings, the Make Lab rises from the Mill Race and is oriented toward downtown Springfield with a large transparent face that engages the public with the process of making. The public park that occupies the north bank of the Mill Race becomes the auditorium, while the Make Lab itself is the stage. The actors, engaged in production, present a new face for Booth Kelly and renew the public’s connection to its history and place.



RESTORING SYSTEMS COMMUNITY The Make Lab serves as both a community resource and business incubator, elevating the presence and visibility of craft and production in Springfield. PRODUCTION The Booth Kelly lumber mill once employed nearly half of Springfield’s workforce. Today, a handfull of businesses occupy the site, but their presence is largely unknown to the public. The site infrastructure and buildings face increasing maintenance pressure, and yet the location just south of downtown Springfield is ideally suited to elevate the community of craft and production in Springfield’s identity. ECOLOGY The millrace restoration brings with it a new experience of ecology and natural systems for Springfield. The wetland park will encourage visitors and wildlife with a network of walking paths through a diverse range of habitat types.

A CROSS-POLLINATION OF IDEAS The Make Lab serves not only as a way to engage the public with a culture of craft and the process of production, but it also exposes the users of the workspace to new materials, techniques and creative processes. The organization of the workspace encourages people to work side by side with people who are using different materials, assembly techniques or processes from their own. This collaboration and cross-pollination helps build a community of craft.

Eugene Passive House Arch 510: Passive House Design and Detailing | Instructed by Matt Hogan Project completed with Alex Froehlich Energy and performance modeling with PHPP, THERM, and WUFI

EXPRESSIVE PERFORMANCE

The intent of this project was to design a house that required minimal energy input to heat and cool the living space. The Passive House standard makes specific requirements for the performance of the building, including annual heating demand, infiltration and air tightness, and primary energy use. A Passive House must be designed with a keen understanding of the local conditions of its site, and the building assemblies that we specified for this house are ideally suited for the mild, wet winters, and hot, dry summers of the Pacific Northwest.

KEY CONCEPTS:

1. CREATE A PASSIVE HOUSE FOR EUGENE’S CLIMATE WITH AN ELONGATED FOOTPRINT While many Passive House advocates push the importance of a low surface to volume ratio for minimizing envelope losses, we considered this project as an opportunity to demonstrate the type of performance expected of wall, floor and roof systems for an elongated building, and the resulting character of the house.

2. INSULATE WITH CELLULOSE Considering the high embodied energy of foam insulations, we challenged ourselves to complete the thermal envelope of all assemblies with cellulose. This necessitates using a framed floor system over a crawl space, rather than using a slab on grade, which would need to bear on a thick pad of foam to achieve a baseline insulation level required for Passive House certification in Eugene, OR.

3. CELEBRATE THE LUNGS OF THE HOUSE

Recognizing that the mechanical system and the heat recovery ventilator comprise the engine of a Passive House, we chose to expose and express the presence of the duct work in the house. Custom brackets integrated into the tension rods of the roof truss hold the duct runs in the vaulted living space.

4. USE COMMONLY AVAILABLE MATERIALS The wall system is comprised of a thick outer wall of double-stud construction, using 2x4’s 24” on center. The OSB sheathing on the interior of the inner wall serves as both the wall’s shear and air barrier. Interior of the double stud wall is an insulated utility chase framed with 2x4’s, 24” on center.



THERM Analysis of Heat Loss Through Building Assembly Connections THERMAL BRIDGE-FREE CONSTRUCTION

Wall to Wall Intersection (plan view):

Color Infrared Imagery

Critical to preventing heat loss are building assembly connections that prevent direct pathways for heat to transfer in and out of the building. The wall-to-wall and wall-to-floor connections are detailed so that there is a continuous layer of cellulose insulation throughout the building envelope. The assembly details were modeled in THERM, and show an even rate of heat transfer from interior to exterior - an indication of thermal-bridge free construction.

Living Canoe Center Victoria, British Columbia | Fall 2011 | Studio led by Johnpaul Jones, FAIA Cultural Research, Programming, Site Selection, Schematic Design

SUSTAINING AN ANCIENT CRAFT Indigenous peoples of the maritime Northwest used canoes as a means to gather food, fish, travel and trade. Canoes were an integral part of their world view, representing their cultural identity, and linking life on land with life in the sea. The Living Canoe Center aims to reconnect Natives from throughout the Northwest to the canoe culture upon which their histories and culture is based. To see the world from within a traditional canoe in the waters of the Salish Sea is to make a profound connection to one’s ancestors through first hand experience, further augmented through the practice of canoe building and related crafts, and the exchange of stories and oral histories.

VILLAGE ORGANIZATION The small, heavily wooded site suggests dividing the project into several related but separate buildings. The pieces of the program sit within the stands of trees, grounding the project and reminding visitors that the craft of canoe-making is entwined with the natural world. The assemblage of buildings recalls traditional Indigenous Northwest village organization.



WORKSPACES THAT OPEN UP The carving space and the small crafts studio each promote craft through close contact with the natural world. Sliding doors allow carvers and weavers to hear the sounds of gulls and shorebirds, feel the breeze, and smell the scents of the site’s native plants as they change with the seasons. The carving space uses an open jointed sheathing system that allows the ambient exterior humid air to circulate through the space and canoes under construction.



TRADITIONAL STRUCTURE CONTEMPORARY ADAPTATION The Living Canoe Center’s four buildings use a round post and beam structural system, traditional to indigenous building practice on the Northwest coast. The carving space uses an open jointed sheathing system to provide security and a sense of containment when the doors are slid shut. Air is allowed to flow through the gaps, slowing the drying of the cedar logs and canoes inside. The roof is made of translucent polycarbonate planks, assembled in an alternating concave up, concave down rhythm. Traditional cedar roof planks were assembled in this fashion, creating dozens of channels for water to drain. In this contemporary adaptation, the planks allow diffuse light to bathe the workspace below. The space is sheltered, but feels outdoors.

Stepping Stone | A Net-Zero Rest Area for the Great Salt Desert Great Salt Desert, Utah | Fall 2010 | Lyceum Competition led by Erin Moore Competition Submission, Site Analysis, Schematic Design

TEMPORARY EXISTENCE Western Utah has a history of fluctuation. Ancient Lake Bonneville, said to have been at one time larger than present-day Lake Michigan, has disappeared and reappeared as many as 28 times over its geological history. In its wake, a seemingly endless desert of salt stretches one’s sense of distance and perception of time. Most visitors experience the Great Salt Desert as an indistinct blur of white from the highway. Stepping Stone lets travelers touch down in the heart of this scaleless landscape and discover the details that make the Great Salt Desert unlike anywhere else on Earth. The rest area takes its form from stepping stones markers of temporary rest along a journey, through landscapes and waterscapes that one would not ordinarily be able to stop were it not for the stepping stone. As in a river, the stepping stones are occasionally reconfigured by forces of a larger scale than themselves. Stepping Stone is designed to acknowledge that its utility hinges on the continued presence of travelers through this slice of the Great Salt Desert. At present, petroleum-based transportation and the Interstate Highway System keep a regular supply of visitors to Stepping Stone, but the future of such travel is uncertain. Should circumstances shift and the I-80 corridor becomes obsolete for transportation, Stepping Stone is designed to be disassembled; its reusable components taken elsewhere, and its rammed-earth walls used to fill the tunnel under the West-bound lane of I-80 that was the source of earth during construction.




Rather than imbed the rest area into the Great Salt Desert, the buildings and pathways of Stepping Stone are elevated above the ground. They rest on the salt, being of this place, but not rooted specifically to a single location. The modules of enclosed or sheltering space and the pathways that link them hover above the desert, locked in place under dry and calm conditions, but are released by the seasonal flooding of the winter months and are rearranged by the forces of wind and water.


PASSIVE AND ACTIVE STRATEGIES TO TARGET NET-ZERO ENERGY High performance south facing windows allow sunlight to warm the interior mass for extended heating. Thermally massive rammed earth walls collect and store solar energy and moderate indoor temperatures.

Floor absorbs solar energy and insulates conditioned space from exterior temperature swings.

Roof collects rain, heats water and produces electricity.

Solar chimney enhances natural ventilation. Warming air in the tower rises, pulling cool fresh air from below the floor into the building.

SEASONAL MOVEMENT Locked in place for nearly half the year, the rest area is released by seasonal flooding and rearranged by the forces of wind and water.

June-November: Rest area anchored on dry salt.

December: Winter flooding and strong east winds begin to reconfigure the rest area.


January: Winds from the northwest.

February: Strong winds continue from the northwest.

March: Winds shift to the south.

April: Winds become northwesterly again as flooding begins to recede.

May: Strong winds from the south give the rest area its final configuration before flooding begins again in December.


Insert // Table Work completed in collaboration with Trygve Faste, Assistant Professor of Product Design, University of Oregon as part of a Graduate Research Fellowship. Concept: Ceramic components fit neatly into interchangeable bench/table inserts with holes cut through them. This allows for many different configurations depending on the desired use.
