JIM AND DE BBIE FIE LDS E ASTSIDE 61915 PE TTIGRE W ROAD BE ND, ORE GON 97702 THE Design Statement The design of the E astside Cohousing Community is based on the concept of connecting the agrarian nature of thFields’ Farm to the surrounding context of suburbia. The geometric form of the clusters relates to the built environment of the context, while the perma- culture and the path that connects the communities SITE creates the agrarian feel of the farm. Both of the compositions create a cohesive bond of the built environment of the whole to the natural world of the farm. Our group also placed a large emphasis on creating a self-sustainable community through architectural design and site orientation. The massing of the housing units relates to the farm in a number of ways. The combinations of the cedar siding gives the appearance of the classic “rustic barn”, creating an inviting aura around the clusters. The rectilinear forms and massings of the buildings reflect the style of the barn, the sym- bol and lifeblood of a farm. The shed roofs give a contemporary twist to the classic style, creating a dialogue between the new and old. The architectural massing of the com- mon house was created in the form of a barn, tying in the roots of the site to the needs of the cohousing community.

COHOUSING West Elevation 1/8” = 1’ 0” C O M M East Elevation 1/8” = 1/0” O N H The design of the common house is based on the concept of combining a traditional barn look with a touch of modern O style. The main goal for the design of the community building Guest has been to make it an inviting space. From the main road in Bathroom front of the common house, people walking or driving by can see its grand facade and feel welcome. Once inside, U Guest Room Guest Room South Elevation 1/8” = 1’0” visitors and members of the community can enjoy the spacious floor plan and high cielings. Based on an open plan, the main floor provides many different functions including Second Floor Plan 1/8” = 1’0” S a very large dining room and kitchen for community dinners. Also, located above the ground floor are two guest bedrooms to accomodate visitors to the Eastside Cohousing Community.

This is more than plenty of square footage to provide power and electricity to the building. After figuring in the medium size refrigerator, ceiling fans, lights, and miscellaneous appli- ances in the kitchen, only about 182 square feet of paneling is absolutely needed to fully run on solar power. Because the common house’s appliances won’t be used around the clock like in one of the units, the total wattage per day used up is minimal. Integrated with the passive solar design, the PV panels provide ample electricity for the common house. Looking toward the future, we envision more installations of panels around the site which will provide for the units.

The gutter for each unit would be equipped with a drain that runs to a underground cistern. In the spring and other times of heavy rain and snow the cistern would fill up and would uti- lize a pump that would circulate the grey water up to the surface. This process will allow for all centralized areas within our clusters to completely sustain themselves without the aid of a gridded water system. If used properly, based on average rainfall patterns through the Bend area, every cistern within each cluster could collect up to 50,000 gallons per year.

The use of Fly Ash con- crete over regular Portland Cement concrete has many sustainable perks to it. The Fly Ash reuses the waste from coal burning plants, allows for the reduction of energy in the production of new materials, conserves mate- rials, and reduces pollution from the coal burning plants and the creation of new Portland Cement compounds. Not only is Fly Ash a sustainable option for concrete, but it also has increased structural strength, reduced per- meability, reduced corrosion of the reinforced steel, reduced production cost, and increased sulphate resis- tance. The use of the concrete massing underneath the units allows for natural passive heating through ther- mal massing. The daylight acquired from the southern orientation heats the concrete throughout the day, then radiates the heat preserved back into the units during the night. The use of the passive solar heating negates the needs of HVAC systems to heat and cool, creating a lower cost of living and reduced energy consumption.
