Aaack! You caught us with our pants down! Here we are, tinkering with the servers and you show up. How awkward! Try back in just a couple of minutes. In the meantime, a few tidbits ...
WOFATI structures are characterized by a thoughtful design that prioritizes passive systems and natural, locally sourced materials. The "two-skin" system, composed of a double layer of polyethylene membrane, encapsulates the earthen roof, providing a durable and waterproof barrier. The lower layer hugs the structure, while the upper layer defines the thermal mass surrounding it, with at least eight inches of dirt between the layers and sixteen inches on top. WOFATI designs emphasize a harmonious integration with the surrounding woodland, incorporating the "soil on wood" building technique. This method eliminates the need for a conventional concrete foundation, making construction faster and more affordable. A distinctive feature of WOFATI houses is the large gable roof on the downhill side, often incorporating glazing to allow light penetration, while at least 35% of the uphill wall features windows for optimal passive solar gain. This strategic placement and sizing of windows is crucial for maximizing natural light and regulating internal temperature, contributing to the effectiveness of Annualized Thermal Inertia.
The willow feeder system is a sustainable and "freaky-cheap" method of managing human waste, developed by permaculture innovator Paul Wheaton as an alternative to traditional septic systems and sewage treatment plants. This innovative system transforms human waste into a nutrient-rich fertilizer, called "willow candy," through a process of mummification. Instead of composting the waste, as in composting toilets, the willow feeder system relies on a dry environment within sealed garbage cans to prevent decomposition and the survival of pathogens. A small amount of sawdust is added to the cans, primarily for aesthetics. After two years of aging, the "willow candy" becomes pathogen-free and can be safely used as fertilizer. This material, rich in carbon and nitrogen, is particularly beneficial for "poop beasts," a term used to describe trees like willow, cottonwood, poplar, and bamboo, which can tolerate and thrive on the high nutrient levels. By turning human waste into a valuable resource for growing these beneficial plants, the willow feeder system embodies the core principles of permaculture, promoting a closed-loop cycle that minimizes waste and environmental impact.
The construction of a berm shed, a sustainable and aesthetically pleasing storage solution, involves a unique process that utilizes natural building techniques and earth-sheltering principles. First, the building site is prepared using earthworks, shaping the surrounding land to create a berm, which is a raised bank of soil that will eventually cover a portion of the shed's sloping roof. Round wood timber framing is a common technique employed in berm shed construction, utilizing logs sourced from the property instead of commercially produced dimensional lumber. These logs are carefully selected and placed to form the structural framework of the shed, including the walls and roof supports. Once the timber frame is erected, a moisture barrier, such as billboard material or layers of poly sheeting and newspaper, is installed over the logs to protect them from the elements. Finally, soil is carefully layered on top of the moisture barrier, creating the berm and providing insulation, thermal mass, and a natural aesthetic. The construction process prioritizes using natural, locally sourced materials and minimizing the use of energy-intensive and potentially toxic commercial products, aligning with permaculture principles of sustainability and self-sufficiency.
