WOFATI, an innovative sustainable building technique coined by permaculture advocate Paul Wheaton, stands for Woodland Oehler Freaky-cheap Annualized Thermal Inertia. The design utilizes readily available natural materials like wood and earth to create a "soil on wood" structure that harmonizes with the surrounding woodland. The "freaky-cheap" construction methods pioneered by Mike Oehler and further developed by Wheaton significantly reduce building costs. WOFATI structures are characterized by a double layer of membrane, a "two-skin" system that encapsulates the earthen roof, ensuring dryness and longevity. The principle of Annualized Thermal Inertia is key, using the earth's mass to regulate temperature, providing passive heating in winter and cooling in summer. WOFATI houses feature large windows on the uphill side for optimal passive solar gain, while the downhill side typically boasts a large gable roof, also incorporating glazing for natural light penetration. Allerton Abbey, located at Wheaton Labs, serves as a prime example of a WOFATI house

Rocket mass heaters are better than wood stoves because they run cleaner and use less wood. Wood stoves lose a lot of heat out the chimney that the rocket mass heater stores in the mass. 75% efficient wood stoves are often run at 3% efficiency at night. Rocket mass heaters use the mass to keep things warm at night.

"HUSP," an acronym for "Horticulture of the United States of Pocahontas," is a term coined by Paul Wheaton to explore a fictional scenario where Native American agricultural practices, similar to permaculture, dominated the United States. This concept envisions an alternate history where Pocahontas, depicted as a brilliant strategist, prevents European colonization, leading to the establishment of the United States of Pocahontas (USP). Within this fictional nation, agricultural practices prioritize respect for the Earth, rejecting destructive methods like plowing and the use of petroleum-based fertilizers and pesticides. HUSP speculates on the potential for superior agricultural output and societal well-being through these nature-centric methods. Wheaton uses the HUSP concept to inspire innovation and advancement within the existing permaculture community, aiming to accelerate progress towards more sustainable and effective food production systems. He proposes a collaborative project involving practitioners of various agricultural approaches, including permaculture, biodynamic, and native plant specialists, working on a 2000-acre plot divided into smaller chunks. This project aims to foster knowledge exchange and accelerate the development of HUSP principles in the real world.

A berm shed, as detailed in the sources, is an innovative and sustainable approach to building storage structures. It seamlessly integrates with the landscape, offering both aesthetic and functional benefits. Constructed using natural building techniques and readily available materials like logs and earth, a berm shed minimizes both environmental impact and construction costs. Its defining feature is the sloping roof covered with soil, forming a natural berm that provides excellent insulation and temperature regulation. The construction often employs round wood timber framing techniques, utilizing logs instead of dimensional lumber, which further enhances its sustainability and rustic appeal. Earthworks, carefully shaping the land to create the berm and ensure proper drainage, play a crucial role in its construction. The berm shed aligns perfectly with permaculture principles, serving as a visual and sound barrier, increasing privacy, and potentially even creating a microclimate beneficial for plant growth around the structure. This unique design, combining natural materials and earth-sheltering principles, offers a durable, cost-effective, and visually appealing storage solution that blends harmoniously with its surroundings.

WOFATI structures are characterized by a thoughtful design that prioritizes passive systems and natural, locally sourced materials. The "two-skin" system, composed of a double layer of polyethylene membrane, encapsulates the earthen roof, providing a durable and waterproof barrier. The lower layer hugs the structure, while the upper layer defines the thermal mass surrounding it, with at least eight inches of dirt between the layers and sixteen inches on top. WOFATI designs emphasize a harmonious integration with the surrounding woodland, incorporating the "soil on wood" building technique. This method eliminates the need for a conventional concrete foundation, making construction faster and more affordable. A distinctive feature of WOFATI houses is the large gable roof on the downhill side, often incorporating glazing to allow light penetration, while at least 35% of the uphill wall features windows for optimal passive solar gain. This strategic placement and sizing of windows is crucial for maximizing natural light and regulating internal temperature, contributing to the effectiveness of Annualized Thermal Inertia.
