Wild Chick Farm
Wild Chick Farm. In the fall of 2005 Sarah Brunner and Shail Pec-Crouse, started a commercial pastured chicken operation in Arcata, California. The first four months see update of business were spent learning from other successful models, experimenting with different equipment, suffering through trials and tribulations, getting our hands bloody and planning improvements to our system. Throughout it all we have been guided by our core values of humane husbandry and sustainability.

We began with a very small flock of 175 birds and decided to try two different models of raising them on pasture to see which model worked the best for our situation. We compared the two models by looking at efficiency, loss to predators, land impact cost, fossil fuel use and mobility which strongly effects efficiency, land impact and fossil fuel use. After working with both models for a couple of months we came to the conclusion that the Chicken Tractor (CT) model is most appropriate for raising meat chickens and the Hoop House (HH) model is more appropriate for raising laying hens. The CT is better for meat production because it is more cost effective and mobile and there is less predation. The CT is also important for pasturing laying hens for their first few months since there are less predator risks. The Hoop House is better for egg production because it accommodates nest boxes and roosts.

Kiva's straw bale greenhouse
An alternative or natural building involves a range of building systems and materials that place major emphasis on sustainability. Ways of achieving sustainability through natural building focus on durability and the use of minimally processed, plentiful or renewable resources, as well as those that, while recycled or salvaged, produce healthy living environments and maintain indoor air quality. Natural building tends to rely on human labor, more than technology. As Michael G. Smith observes, it depends on "local ecology, geology and climate; on the character of the particular building site, and on the needs and personalities of the builders and users."

The basis of natural building is the need to lessen the environmental impact of buildings and other supporting systems, without sacrificing comfort, health or aesthetics. To be more sustainable, natural building uses primarily abundantly available, renewable, reused or recycled materials. The use of rapidly renewable materials is increasingly a focus. In addition to relying on natural building materials, the emphasis on the architectural design is heightened. The orientation of a building, the utilization of local climate and site conditions, the emphasis on natural ventilation through design, fundamentally lessen operational costs and positively impact the environmental. Building compactly and minimizing the ecological footprint is common, as are on-site handling of energy acquisition, on-site water capture, alternate sewage treatment and water reuse.

ENGR 215 Introduction to Design projects – Spring 2010: RCEA: Two labs of the Spring 2010 semester of Engineering 215 worked with the Redwood Coast Energy Authority to build energy education boxes for classrooms in Humboldt County. These boxes are designed for different K-12 grade ranges and cover one of three topics: energy conservation, renewable energy or climate change.
