SLIDE 1 Primary-Secondary Spaces Circulation Bend, Central Oregon Fields’ Farm 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 permaculture and the path that connects the communities 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

n 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

f 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 common house was created in the form of a barn, tying in the roots of the site to the needs of the cohousing community.

THE SITE

PASSIVE SOLAR (FL Y ASH) ACTIVE SOLAR (PV PANE LS) Put at the correct angle for Bend, pv panels can provide plenty of electrcity to power many house- hold needs and appliances. Com- bined with passive solar strate- gies, a bill from the electric com- pany will be next to nothing. On

ur site, the panels will be placed

mostly on the common house and

n covered parking installations.

RAINWATE R HARVE STING E ven in a dry high desert climate, rainwater harvesting can be extremely effective, especially when used in cases such as our project where only greywater is

required. Using simple drainage

systems even on very conven- tional houses can create a large quantity of rainwater that can go to irrigate the gardens within our clusters. Design Statement

Site Plan 1/ 32” = 1’0”

Fly Ash is a spherical by-product from the combustion of coal. The Fly Ash is combined with lime and water to produce a compound that is able to replace 15-25% of the Portland Cement in cement

mixtures. The Flyash affects the

plastic properties of the concrete by improving workability, reducing water demand, and low- ering the heat of hydration. Fly Ash concrete has the same properties and applications as regular concrete Pacific Northwest Ground-Figure Diagram

PV PANELS

About 528 square feet of PV paneling is located on the top of the roof on the common house. 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 appliances 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.

f combining a traditional barn look with a touch of modern
style. The main goal for the design of the community building

has been to make it an inviting space. From the main road in front of the common house, people walking or driving by can see its grand facade and feel welcome. Once inside, 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 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.

The shed roof look that we designed for our units maximizes the amount of water that could be collected for the humble square footage that our units have. 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 concrete foundation of the units is composed of a 25% Fly Ash concrete composition. The use of Fly Ash concrete 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 materials, 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.
