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 ...

Beyond the foundational elements of WOFATI design, there are advanced concepts that further enhance its effectiveness and versatility. The strategic placement and sizing of windows on the uphill side, for instance, are crucial for optimizing passive solar gain and regulating temperature. The design of the "two-skin" system, incorporating a double layer of membrane, demands careful consideration of materials and installation techniques to ensure long-term dryness and durability. The integration of WOFATI principles with other sustainable technologies, such as rocket mass heaters, offers the potential for a highly efficient and self-sufficient dwelling. The concept of WOFATI extends beyond just houses; variations such as WOFATI coolers and freezers, utilizing specialized venting systems and expanded thermal mass, showcase the adaptability of this approach to address various needs. Furthermore, WOFATI principles can be applied to animal shelters, with specific modifications to accommodate larger spaces and functionality. The ongoing development and experimentation at Wheaton Labs, as seen in projects like Allerton Abbey and Wofati 0.8, continue to push the boundaries of WOFATI design and its potential for sustainable living.

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.

Hugelkultur offers advanced techniques and benefits for sustainable gardening and food production. This permaculture method utilizes buried wood to create raised garden beds, fostering a thriving ecosystem that reduces reliance on external inputs. As the wood decomposes, it transforms into "a sponge to hold water," decreasing irrigation needs and attracting beneficial microorganisms that enhance soil fertility. The shrinking wood creates air pockets, naturally aerating the soil and promoting a "self-tilling" effect. This "soil on wood" technique enhances soil health by creating "parking spaces for water and nutrients", ultimately minimizing the need for fertilizers. Hugelkultur beds can be constructed on varying scales, from small gardens to large farms, and are particularly well-suited for locations with limited rainfall, such as deserts. This versatile approach allows gardeners to cultivate diverse "garden plants" while minimizing environmental impact.
