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 ...
Dry outhouses, frequently discussed in permaculture, provide a sustainable sanitation solution that prioritizes resource conservation and waste reduction, but their usability and effectiveness rely on careful design and management. While simple in concept, dry outhouses require specific considerations to optimize user experience and ensure proper waste handling. Strategic placement on elevated ground promotes natural drainage and helps maintain a dry pit, essential for reducing odors and pathogen survival. However, achieving a truly "no pee" environment, while ideal for minimizing volume and toxicity, can be challenging, especially for women. Urine diversion mechanisms are crucial for separating urine, a valuable fertilizer, and facilitating a drier composting process for the solid waste. The addition of sawdust further aids in odor control and composting, while proper ventilation, often achieved through a "breather pipe" in a willow feeder system, ensures aerobic decomposition and minimizes smells. User comfort can be enhanced with features like comfortable seating, adequate lighting, and clear instructions on proper usage, including sawdust application and urine diversion practices. Effectiveness in terms of long-term sustainability hinges on proper waste management. The "mummified" waste, or poop-jerky, after two years of aging, is ideally applied to "poop beast" trees like willows, poplars, or cottonwoods, completing the nutrient cycle. By addressing usability and effectiveness through thoughtful design and management, dry outhouses can become a viable and environmentally sound sanitation solution, embodying the principles of permaculture.
The berm shed, a hallmark of permaculture design, is an eco-friendly, earth-sheltered structure renowned for its unique construction techniques. Earthworks are fundamental to its creation, as the surrounding landscape is carefully shaped to form the berm that will encase a portion of the shed's sloping roof. This berm serves a dual purpose, acting as both a natural insulator and a source of thermal mass, effectively regulating the internal temperature. The structural framework of the berm shed is often built using round wood timber framing, a technique that prioritizes using logs instead of conventional dimensional lumber, further enhancing its sustainable appeal. However, the longevity of these logs, especially when in contact with soil, is a crucial consideration. The sources recommend peeling the bark from posts before burying them, a technique born from experience and aimed at minimizing the risk of rot. Another technique for ensuring the durability of the structure involves incorporating gravel into the post holes. The gravel facilitates drainage, preventing water from pooling around the base of the posts and contributing to premature decay. These carefully considered details, combined with the innovative "attic" cell design at the termination ends of the shed, as described in source, showcase a commitment to sustainable building practices that go beyond mere functionality, exemplifying the core principles of permaculture.
WOFATI structures excel in effectiveness due to their emphasis on passive design principles, particularly Annualized Thermal Inertia, which utilizes the earth's thermal mass to regulate temperature fluctuations. By strategically incorporating design elements like large windows on the uphill side and a substantial gable roof on the downhill side, WOFATIs maximize passive solar gain, further reducing the need for artificial heating and cooling. This results in significant energy savings and reduced reliance on external energy sources. The use of locally sourced, natural materials, primarily wood and earth, in WOFATI construction minimizes the environmental impact associated with manufacturing and transportation of building materials. The "two-skin" system, a double layer of membrane encapsulating the earthen roof, ensures dryness and longevity, enhancing the building's overall effectiveness and sustainability. As seen in Allerton Abbey, the first WOFATI built at Wheaton Labs, these structures successfully demonstrate the practicality and efficiency of this building technique
The SKIP program, which stands for Skills to Inherit Property, is primarily facilitated through the online platform permies.com, a website dedicated to permaculture and sustainable living. Aspiring homesteaders, called "Skippers," engage with SKIP on permies.com by creating free accounts and choosing "Badge Bits" (BBs) to complete from the PEP (Permaculture Experience according to Paul) curriculum. These BBs are practical projects that demonstrate essential skills for sustainable living, and Skippers document their accomplishments by uploading photos and videos to permies.com. The documentation is then reviewed and verified by the permies.com community, ensuring quality and adherence to program standards. Skippers earn badges as they complete BBs, showcasing their progress and expertise in various skill areas. "Otis," the fictional representation of landowners seeking to pass on their properties, can then browse the profiles of Skippers on permies.com to find a suitable match. The permies.com forums provide a space for Skippers to connect, share experiences, and seek guidance, further supporting the SKIP program's community-driven approach.
