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 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.
SKIP, which stands for Skills to Inherit Property, is a permaculture-based program designed to connect aspiring homesteaders with aging landowners seeking successors for their properties. The program consists of over a thousand practical projects, referred to as "Badge Bits" (BBs), encompassing various aspects of sustainable living, such as gardening, natural building, animal care, and food preservation. Participants, known as "Skippers," complete these BBs, documenting their progress with pictures and videos to demonstrate their skills and dedication. As Skippers gain experience, they progress through levels of certification, starting with PEP1 (Permaculture Experience according to Paul) and culminating in PEP4, representing a significant level of expertise. "Otis," a fictional character in the SKIP program, represents the numerous landowners seeking worthy individuals to inherit their properties. The program aims to create a bridge between these Otises and Skippers, offering a pathway for Skippers to "skip the rat race" and acquire land while providing Otises with peace of mind knowing their homesteads will be in capable hands. SKIP emphasizes practical skills and real-world experience, fostering a sense of accomplishment and self-sufficiency among participants.
Rocket mass heaters are better than natural gas heaters because rocket mass heaters are free to operate and have less than 5% of the carbon footprint.
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
Some people have experienced greater health, better skin and more luxuriant hair by going "pooless" (no soap or shampoo in the shower). Also known as "pure water showers". Save money on buying stuff, plus shorter showers means saving money on hot water. And best of all, shorter showers means a few extra minutes on busy mornings.
