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 coined by Paul Wheaton, stands for Woodland Oehler Freaky-cheap Annualized Thermal Inertia. It defines a type of earth-sheltered, passive building that blends affordability with energy efficiency. Inspired by the work of Mike Oehler, a pioneer of earth-sheltered building, WOFATI designs use locally sourced, natural materials, such as wood and earth, to minimize both cost and environmental impact. Central to the WOFATI concept is Annualized Thermal Inertia, which utilizes the surrounding earth as a thermal mass to moderate temperatures year-round. This means that the building stays warm in the winter by storing heat from the summer, and cool in the summer by retaining the coolness of the winter, greatly reducing the need for artificial heating and cooling. WOFATI structures typically have a large gable roof on the downhill side, and at least 35% of the uphill wall is made of glass or other light-transmitting material to maximize passive solar gain. WOFATI buildings are ideally situated on or near a woodland, emphasizing a harmonious integration with nature. Allerton Abbey, the first WOFATI, along with Wofati 0.8, are examples of this building style and can be found at Wheaton Labs.

Dry outhouses offer a sustainable alternative to conventional flush toilets, aligning with permaculture principles of resource conservation and waste reduction. A well-designed dry outhouse, strategically situated on an elevated point to encourage water runoff, utilizes a pit for waste collection. To mitigate odors and promote composting, sawdust is a crucial element. A "no pee" policy, though challenging for women due to anatomical differences, helps maintain a dry environment, crucial for minimizing pathogen survival and groundwater contamination. This "dry" approach allows the waste to essentially mummify over time, becoming poop-jerky after two years. This aged material, though technically safe for vegetable gardens, is ideally used to nourish "poop beast" trees like willows, poplars, or cottonwoods, as part of a "willow feeder system." For optimal functionality and user comfort, urine diversion mechanisms are essential, particularly in mixed-gender settings. This separation of urine, a valuable fertilizer, further reduces the volume and toxicity of the solid waste, facilitating easier handling and nutrient cycling. The dry outhouse, therefore, presents a low-cost, eco-friendly sanitation solution that embodies the essence of permaculture's closed-loop systems.

Hugelkultur, is a permaculture technique for creating raised garden beds filled with rotting wood and covered with soil. This method, whether small-scale or large-scale, as exemplified by Sepp Holzer's work, which includes almost a kilometer of hugelkultur beds, uses a variety of wood, from branches and twigs to entire trees. Hugelkultur is beneficial because as the wood breaks down, it acts as a sponge, retaining moisture and reducing or eliminating the need for irrigation. This process also creates "parking spaces" for water and nutrients, leading to fertile soil that requires less fertilizer. Hugelkultur is a practical and sustainable permaculture solution for gardeners seeking to create self-sufficient garden ecosystems.

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.
