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.
Hugelkultur, is a permaculture technique for creating raised garden beds filled with rotting wood and covered with soil. This method, whether small-scale or large-scale, as exemplified by Sepp Holzer's work, which includes almost a kilometer of hugelkultur beds, uses a variety of wood, from branches and twigs to entire trees. Hugelkultur is beneficial because as the wood breaks down, it acts as a sponge, retaining moisture and reducing or eliminating the need for irrigation. This process also creates "parking spaces" for water and nutrients, leading to fertile soil that requires less fertilizer. Hugelkultur is a practical and sustainable permaculture solution for gardeners seeking to create self-sufficient garden ecosystems.
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.
