Living Machines
Marc Companion of Ocean Arks, Inc. will conduct a three-part workshop where you will design and build a living machine that mimics biological ecosystems to filter and treat wastewater without chemicals. Each workshop session builds off the other but participants may attend one, two or all three.
Sat. 1:30-3:00; Sat. 3:30-5:00; Sun 9:30-11:00

Ecobuilding
Come play in the mud! Mark Lamberth will demonstrate one of his favorite natural building techniques. Light straw clay is a building technique indigenous to Germany. This highly insulating material is a mixture of straw and clay packed between forms in a standard stud frame wall. There will be hands-on work as well as discussion. You are welcome to watch and listen from a clean distance or if you want to work hands-on wear clothes you don’t mind getting dirty.
Sat. 1:30-3:00

Solar Electric (PV)
These workshops will be led by the Energy Service Company, local experts and community partners in the installation and education of active and passive renewable energy systems. Learn the fundamentals of good PV design and installation. Hands-on approach to the modules, controllers, inverters, batteries and balance of system (BOS) components required for grid-tied or stand-alone applications, load analysis and system sizing. Several topics will be discussed: tax incentives, net metering and connecting to the Grid, hybrid generator/PV/wind/hydro systems, common installation problems, and safety and performance issues.
The Energy Service Company is the culmination of over 30 years of experience in the design, sales and installation of solar energy systems with over 4000 installations. Through years of keeping abreast of new technical innovations and ongoing education, they have become recognized as the unmatched authority in the field of solar energy.
Sat. 3:00-5:00; Sun. 11:15-12:30

Hydrogen: Small Engine Conversion
The American Hydrogen Association Northwest Chapter volunteers will lead a demonstration workshop explaining the technology and application of hydrogen as a renewable energy carrier. They will discuss several sources and production methods of hydrogen and give instructions on how to convert BBQ’s and small engines to run on hydrogen. This will also include a hands on engine tear down and rebuild.
Sun. 9:30-11:00
Workshop Coordinator: John Krausser

Solar Geometry
Throughout human history, the path of the sun across the sky has influenced building practices and cultural traditions. Today, however, many structures are erected with little or no thought given to the impact of the sun on the site and building. This workshop begins in space, looking at planetary orbits to provide an understanding of how solar geometry varies during the year. We come back to Earth to study solar access on a site. A simple tool called the Solar Transit allows us to predict the sun’s path through the sky at any time of year.
Sun. 11:15-12:30

Joshua Cohen
Cohen is a graduate teaching fellow at the University of Oregon. Before coming to UO to pursue an M.Arch degree, he learned about solar geometry while designing spacecraft for a small aerospace company. Now he applies this knowledge to issues of solar access and daylight in buildings.

Natural Wall Finishes
Many cultures of the world continue to rely on centuries-old technologies to make the places they inhabit beautiful. With this workshop, put on by the founders of Yolo, you will learn how to manipulate different types of paint bases such as natural resins, oils, beeswax, pigments and fillers to achieve a multitude of effects that will give depth and richness to your walls that no latex paint could even come close to.
Sat. 10:30-12:00
Workshop Coordinator: Jess Ellingson

Ecoroofs
Come learn the importance of greenroofs and help construct one. Participate in the construction of an ecoroof on top of a demonstration doghouse. This workshop will begin with an introductory presentation by Tom Liptan, a landscape architect from the Bureau of Environmental Services in Portland. He will discuss the ecological benefits of greenroofs, including stormwater retention and temperature control. Then we will install the final felt membrane, soil and sod layers. Time permitting, we will conduct a simple water test to demonstrate the benefits of an ecoroof. Kids are welcome. Construction extends over two workshop periods.
Sat. 10:30-12:00; Sat. 1:30-3:00

Tom Liptan
Lipton is a registered landscape architect in Oregon and works as an environmental specialist with the City of Portland Bureau of Environmental Services. He has been nationally recognized for his work on ecoroofs and other sustainable site design techniques. For the past 11 years, he has been a member of Portland’s NPDES Municipal Stormwater Program. His assignments include research and development of new site and stormwater techniques, ecoroof research and program development, implementation of demonstration projects with public and private partners, stormwater monitoring and preparation of annual compliance reports, city code modifications and education and outreach. He is also an original faculty member of the Urban Watershed Institute, established in 1999.

Weaving H.O.P.E.S.
Weaving is both craft and metaphor in this ongoing interactive sculpture. Literally joining our impressions and intentions in a symbolic web, we will make something better than our own while energizing the potential for collaboration and synergy. Weaving H.O.P.E.S. is a dynamic opportunity to give physical form and artistic expression to the old and new relationships and commitments we forge at this ecological design arts conference.

Hannalei Rozen
Rozen is an independent environmental designer and community advocate in Springfield. Her practice, Placemakers, is concerned with environmental design, research and education in the region. She has a Bachelors of Architecture and Town Planning from Technion, Haifa, Israel, and a BLA and MLA from the University of Oregon.

Trashy Fashion
Join master trashy craftswoman Thandi Rosenbaum in the making of entirely recycled outfits. Using materials collected locally, the workshop will stitch together stylish fashion that will sashay down the runway at the Saturday Night Party to the tunes of Portland band Peter Pants.
