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, represents an innovative approach to sustainable building, coined by permaculture expert Paul Wheaton. This building technique combines the affordability and simplicity of Mike Oehler’s earth-sheltered designs with Wheaton's focus on cost reduction and integration with the natural environment. WOFATI structures prioritize the use of readily available, natural materials, such as wood and earth, minimizing reliance on manufactured products and reducing the building's environmental footprint. Annualized Thermal Inertia, a key principle of WOFATI, utilizes the surrounding earth as a thermal mass, storing heat in the summer to warm the building during winter and retaining cool temperatures from winter to moderate summer heat, thereby minimizing energy consumption for heating and cooling. WOFATI designs typically feature large windows on the uphill side to maximize passive solar gain, further reducing energy needs. WOFATIs are intended to be situated on or near a woodland, embracing the concept of harmonious integration with nature. Notable examples of WOFATI structures, including Allerton Abbey and Wofati 0.8, can be found at Wheaton Labs in Montana.
Hugelkultur, is an advanced permaculture technique that utilizes decomposing wood to create self-sustaining raised garden beds. Hugelkultur beds can be built in various shapes and sizes, using a variety of wood materials, from twigs and branches to logs and even whole trees. The wood, buried under a layer of soil, acts "like a sponge to hold water," creating "parking spaces for water and nutrients," and reducing the need for irrigation. The decomposing wood attracts beneficial microorganisms and releases nutrients, resulting in a rich "soil on wood" environment that reduces or eliminates the need for fertilizers. Over time, the wood shrinks, creating air pockets, making hugelkultur beds "self-tilling". The decomposition process also slightly warms the soil in the first few years, extending the growing season. This technique, which works in diverse climates, allows gardeners to harness natural processes to create thriving, self-sufficient garden ecosystems, embodying permaculture principles
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.
The distinction between "woodland" and "forest" is subtle but significant within the context of permaculture, particularly in Paul Wheaton's approach to Wofati design. While "forest" implies a focus on traditional forestry practices, often associated with monoculture and resource extraction, "woodland" evokes a more holistic and interconnected ecosystem. Woodland management, as exemplified in Ben Law's books The Woodland Way and The Woodland Year, emphasizes sustainable practices that prioritize biodiversity, ecological balance, and human integration with the natural world. A woodland is seen as a space where humans are active participants, nurturing and benefiting from the ecosystem's abundance, similar to the Native American land management practices that inspire the HUSP (Horticulture of the United States of Pocahontas) concept. In contrast, a forest, within this framework, is often viewed as a resource to be exploited, a perspective that aligns with the concerns raised about conifer monocultures and their detrimental impact on biodiversity and soil health. Therefore, "woodland," as used in the context of Wofati, signifies a conscious shift towards a more harmonious and sustainable relationship between humans and the natural world. This distinction underscores the importance of terminology in shaping our understanding and approach to land management within the permaculture movement.
