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, an acronym for Woodland Oehler Freaky-cheap Annualized Thermal Inertia, is an innovative approach to sustainable building developed by permaculture expert Paul Wheaton. WOFATI structures are designed to be eco-friendly, utilizing locally sourced natural materials, primarily wood and earth. These structures are intended to be located on or near woodlands, promoting a harmonious integration with the natural surroundings. Annualized Thermal Inertia, a key element of WOFATI design, harnesses the thermal mass of the surrounding earth to provide passive heating in winter and cooling in summer, thereby minimizing the need for artificial temperature regulation. WOFATI structures are inspired by the work of Mike Oehler, a pioneer in earth-sheltered building known for his simple, "freaky-cheap" designs, which Wheaton has adapted and refined to further reduce construction costs. WOFATI buildings are typically characterized by a large gable roof on the downhill side, with at least 35% of the uphill wall featuring glass or other light-transmitting materials to maximize passive solar gain. Allerton Abbey, the first WOFATI structure, and Wofati 0.8 are both located at Wheaton Labs in Montana and serve as prominent examples of this unique building style.

The berm shed is more than just a simple storage structure; its construction incorporates advanced techniques that prioritize sustainability, durability, and integration with the natural environment. Earthworks play a crucial role, as careful shaping of the landscape is required to create the berm that covers a portion of the shed's sloping roof. This berm acts as a natural insulator and thermal mass, helping to regulate temperature inside the structure. The "attic" cell design, as discussed in source, involves a specific configuration at the termination ends of the berm shed, further enhancing its thermal efficiency. Round wood timber framing, a technique using logs instead of dimensional lumber, is often employed, lending structural strength and a rustic aesthetic. A key consideration is the long-term durability of the wood in contact with soil. Source emphasizes the importance of peeling the bark from posts before burial to reduce the probability of rot, highlighting the evolution of construction techniques for increased longevity. Additionally, using gravel in post holes, as described in source, helps with drainage and further protects the wood from moisture. These advanced concepts, when combined, result in a berm shed that is not only functional and visually appealing but also a testament to sustainable building practices deeply rooted in permaculture principles.

The SKIP (Skills to Inherit Property) program, hosted on permies.com, utilizes a badge system based on the completion of practical projects called "Badge Bits" (BBs). These BBs, categorized under 22 different aspects, encompass a diverse array of skills crucial for sustainable living and homesteading, aligning with the principles of permaculture. To earn a badge, Skippers must complete a predetermined set of BBs within a specific aspect, demonstrating their competency in that area. Badges are tiered, starting with the Sand badge, which signifies basic proficiency and requires approximately 5 hours of work. The next levels are Straw, Wood, and Iron badges, representing increasingly advanced skill levels and significantly greater time commitments. Examples of BBs include carving a wooden spoon (Roundwood Woodworking), building a hugelkultur garden bed (Gardening), installing a light fixture (Electricity), and mending a hole in clothing (Textiles). By completing BBs and earning badges, Skippers showcase their practical skills and dedication to sustainable living to potential "Otisies" (landowners) looking for suitable successors for their properties. Moreover, the completion of BBs contributes to the overall goal of "skipping the rat race," empowering individuals to acquire the skills and experience needed for self-sufficient living.

Beyond the foundational elements of WOFATI design, there are advanced concepts that further enhance its effectiveness and versatility. The strategic placement and sizing of windows on the uphill side, for instance, are crucial for optimizing passive solar gain and regulating temperature. The design of the "two-skin" system, incorporating a double layer of membrane, demands careful consideration of materials and installation techniques to ensure long-term dryness and durability. The integration of WOFATI principles with other sustainable technologies, such as rocket mass heaters, offers the potential for a highly efficient and self-sufficient dwelling. The concept of WOFATI extends beyond just houses; variations such as WOFATI coolers and freezers, utilizing specialized venting systems and expanded thermal mass, showcase the adaptability of this approach to address various needs. Furthermore, WOFATI principles can be applied to animal shelters, with specific modifications to accommodate larger spaces and functionality. The ongoing development and experimentation at Wheaton Labs, as seen in projects like Allerton Abbey and Wofati 0.8, continue to push the boundaries of WOFATI design and its potential for sustainable living.
