WOFATI, which stands for Woodland Oehler Freaky-cheap Annualized Thermal Inertia, represents a sustainable building solution that merges affordability and energy efficiency. Developed by Paul Wheaton, WOFATI draws inspiration from Mike Oehler's earth-sheltered designs, enhancing them with cost-saving strategies and a focus on harmonizing with the surrounding environment. This innovative approach prioritizes using locally sourced natural materials like wood and earth, thereby minimizing reliance on manufactured products and lessening the building's ecological impact. The concept of Annualized Thermal Inertia is central to WOFATI design, harnessing the surrounding earth as a thermal mass to regulate temperature fluctuations throughout the year. This natural heating and cooling system stores summer heat for winter warmth and retains winter's coolness to moderate summer temperatures, significantly reducing energy consumption. WOFATI buildings typically feature large windows strategically placed on the uphill side to maximize passive solar gain, further enhancing energy efficiency. As the name suggests, WOFATI structures are ideally situated on or near a woodland, emphasizing a symbiotic relationship with nature. Examples of WOFATI buildings, including Allerton Abbey and Wofati 0.8, can be found at Wheaton Labs in Montana

Hugelkultur, is an advanced permaculture technique for creating self-sustaining raised garden beds filled with decomposing wood. The technique involves burying a variety of wood materials, including logs, branches, twigs, and even whole trees, under layers of soil, creating a complex and dynamic environment for plant growth. As the wood decomposes, it acts as "a sponge to hold water," reducing the need for irrigation. This decomposition also generates heat, which can extend the growing season, particularly in cooler climates. The shrinking wood creates air pockets, making the beds "self-tilling" and promoting excellent aeration for plant roots. These "parking spaces for water and nutrients," as described by Paul Wheaton, enhance soil fertility, attract beneficial microorganisms, and release nutrients, reducing or eliminating the need for fertilizers. Hugelkultur beds are remarkably adaptable and can be built in various shapes and sizes, as exemplified by Sepp Holzer's large-scale project in Dayton, Montana, which features nearly a kilometer of hugelkultur beds.

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.
