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 SKIP (Skills to Inherit Property) program, designed to connect aspiring homesteaders ("Skippers") with landowners seeking successors ("Otisies"), centers around the completion of practical projects called "Badge Bits" (BBs). To join, create a free account on permies.com and choose BBs from the PEP (Permaculture Experience according to Paul) curriculum. These BBs, encompassing skills like gardening and natural building, are documented through photos and videos, which are then reviewed by the permies.com community. As Skippers complete BBs, they earn progressively advanced badges — Sand, Straw, Wood, and Iron — showcasing their skills to potential Otisies. While the program is free, attending the annual SKIP event at Wheaton Labs, where BBs are taught, costs $2,250. The permies.com forums also play a vital role, providing a platform for Skippers to connect and share experiences.
One Mason bee can pollinate 200 times more flowers than one honey bee. Unlike honey bees, Mason bees are native to North America.
Rocket mass heaters are better than wood stoves because they run cleaner and use less wood. Wood stoves lose a lot of heat out the chimney that the rocket mass heater stores in the mass. 75% efficient wood stoves are often run at 3% efficiency at night. Rocket mass heaters use the mass to keep things warm at night.
When discussing "woodland" versus "forest," the structural and management approaches differ significantly, particularly within a permaculture context. Forests, often managed for timber production, frequently involve monoculture planting and practices like clear-cutting, which can create what Sepp Holzer calls a "conifer desert." This leads to decreased biodiversity, depleted soil health, and disrupted ecological balance. "Woodland" management, as described by Ben Law, focuses on a more holistic, interconnected ecosystem. Woodland management prioritizes biodiversity, recognizing the interconnectedness of all lifeforms within the ecosystem. Active human participation is encouraged, mimicking the sustainable land management practices of Indigenous cultures, as exemplified by the HUSP (Horticulture of the United States of Pocahontas) concept. Woodlands are viewed as spaces where humans actively participate and nurture, promoting long-term health and resilience. This active management ensures the woodland provides not only timber but also food, medicine, and wildlife habitat. The selection of "woodland" in Wofati design reflects a conscious shift away from extractive forestry practices and toward a more sustainable and harmonious relationship with the natural world. In essence, the distinction between woodland and forest highlights the crucial role of human management in shaping the structure and health of these ecosystems, emphasizing the permaculture principle of responsible stewardship of natural resources.
