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 structures demonstrate remarkable effectiveness due to their unique design features and emphasis on passive systems. The "two-skin" system, characterized by a double layer of membrane, protects the structure from moisture, ensuring dryness and longevity. WOFATI designs prioritize the use of natural and locally sourced materials, primarily wood and earth, significantly reducing the building's environmental impact and embodying the "freaky-cheap" philosophy pioneered by Mike Oehler. The core principle of "Annualized Thermal Inertia" harnesses the earth's thermal mass to regulate temperature fluctuations, providing passive heating in the winter and cooling in the summer. Large windows strategically placed on the uphill side, along with a spacious gable roof on the downhill side, often incorporating glazing, maximize passive solar gain, further enhancing energy efficiency. By minimizing reliance on artificial heating and cooling systems, WOFATIs achieve substantial energy savings. Allerton Abbey, the first WOFATI built at Wheaton Labs, exemplifies the practicality and success of this building technique

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

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 willow feeder system, a "freaky-cheap" and sustainable approach to human waste management, was developed by permaculture expert Paul Wheaton as an alternative to conventional septic systems and sewage treatment plants. The system emphasizes a closed-loop cycle, transforming human waste, or "poop", into valuable fertilizer, termed "willow candy". Unlike composting toilets, willow feeders utilize a dry environment created within sealed garbage cans to mummify the waste, preventing composting and the potential spread of pathogens. A small amount of sawdust is added to each can, primarily for aesthetic purposes. This dry process also preserves valuable carbon and nitrogen, which are often lost to the atmosphere during hot composting. After two years of aging, the pathogen-free "willow candy" can be safely applied as fertilizer to "poop beasts" — trees like willow, cottonwood, poplar, and bamboo — which can handle the high nutrient content without being harmed. This system turns human waste into a valuable resource, promoting sustainable gardening practices.

Hugelkultur, meaning "hill culture," is a sustainable permaculture gardening method that uses buried wood to create raised garden beds. This technique involves layering logs, branches, and other woody debris at the base of the bed and covering them with soil. As the wood decomposes, it acts as a sponge, retaining moisture, improving aeration and drainage, and releasing nutrients, reducing the need for watering and fertilizers. Hugelkultur beds are ideal for growing various plants, especially those that prefer well-drained soil. By harnessing the natural process of decomposition, hugelkultur promotes a thriving garden ecosystem and aligns with permaculture's goal of sustainable systems.
