PAHS - Umbrella House

PAHS - Umbrella House
Figure 1 Geodome, the first umbrella home (in idealized form), maintains a 66° to 74° temperature year-round without heating equipment in western Montana’s cold climate. In summer, solar heat radiates in, falls on internal surfaces, and is absorbed into the surrounding soil. The umbrella traps heat in the dry soil until winter, when it migrates back into the house. Figure 2 Twenty feet under the surface, the soil temperature reflects the average ambient air temperature during the year. Figure 3a In summer, air enters the house through an earth tube and is warmed by the sun; moving through the second tube, it warms the cooler soil. Figure 3b In winter, cool air enters, is heated by the warm earth, and passes to the house. Figure 4 Second generation umbrella home in Missoula, Montana was constructed by Tom Beaudette, the engineer of Geodome. We called housing experts all over the country, but no one had any ideas.

Todd Jersey Architecture Residential We were pleased to partner with Susan Feichtmeir in beautifully blending Spanish influences to design and build her 3,000 square foot home in the Sonoma Valley. Perfectly suited to the surrounds' climate and terrain, the stucco walls, courtyard, and cool, shaded interiors make this home well suited for the warm Sonoma Valley climate. Oriented to take full advantage of its near-hilltop setting while shielding the interior from the hot summer sun, the floor plan includes all the features one would want in a Sonoma Valley luxury home including: ten-foot ceilings, a master bedroom suite, library, gourmet kitchen, artists studio and wine storage area. Todd Jersey Architecture prides itself on partnering with its clients to develop a project that is unique to their style and in keeping with the surrounding landscape.

Passive Solar Radiant Slab | Riversong HouseWright A passive solar home requires five elements in order to take full advantage of the free and plentiful heat of the sun: an aperture to let in the sun’s warming rays, a control device to keep them out in the summer, an absorber surface to receive the rays without too much reflection, thermal mass to store the heat until it’s needed, and a distribution system to move the heat to where it’s required. For a house to be truly passive, each of these elements should operate without either mechanical power or occupant intervention. The control system, for instance, is ideally properly-designed overhangs. Solar builders are offered a wide array of “apertures” or window options, and with sufficient demand perhaps manufacturers will begin to offer the kind of highly insulating windows that also offer high solar heat gain coefficients (SHGC, as listed on the NFRC label on new units). Throw in an efficient, outside air-coupled woodstove, and the balancing act becomes more delicate. Like this:

Natural Building 101: Building a Cob House Materials Published on September 12th, 2008 | by ziggy This year, I started building my very own cob house. Cob is an extremely environmentally-friendly natural building material composed of sand, clay, and straw, and it has withstood the test of time and the elements over many past generations all over the world. Haven’t heard of it? Then read on to learn more about this creative, beautiful, and highly ecological building process. What is cob? Cob building dates back hundreds of years ago, and cob houses built over 500 years ago in Europe are still inhabited to this day. The properties of cob Cob structures are monolithic: layers of material are worked together to produce one massive structure, compared to something like adobe, which is typically made into forms that can be stacked like bricks. Cob: beautiful and environmental The main components of cob building – sand, clay, and straw, come directly from the earth, oftentimes right beneath our feet. Cobbing is simple and cooperative (p.s.

Archiplumes | between necessary & sufficient Ecuador Commons ecologie-pratique.org - Construire, restaurer, aménager, cultiver et vivre écologiquement Tortugaboreal: bioconstruccion Por fin el taller está casi funcional, a la espera del enlucido final, y la instalación eléctrica. En mi último post, habíamos llegado a avanzar la parte del gallinero, con la idea de aprovechar esa zona como cocina-galería. Aprovechando la pared de ladrillo del gallinero para hacer unas zapatas corridas de hormigón, donde reposar las vigas del suelo y la futura estufa de leña. Lo mismo al fondo, contra la pared de bloque, en este caso para sostener un banco de cob. Enlazamos el cimiento de piedra donde estaba el muro de ladrillo antes, esa esquinita que veis mojada Dani, y delante de él, el esqueleto de la estufa, con la parte superior de una cocina de hierro vieja que encontré tirada ahí mismo, en el gallinero. Merecido descanso de la cuadrilla, después de poner las lonas en el tejado, y el velux reciclado. Encajando los cristales con la motosierra, en la columna. Como cada cristal es de una medida diferente, el muro va a quedar escalonado. Abrazos a todas!!!

Seasonal thermal energy storage Seasonal thermal energy storage (or STES) is the common umbrella term for several technologies for storing heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months. An example of one of the several kinds of STES storages illustrates well the capability of interseasonal heat storage. STES technologies[edit] There are several types of STES technology, covering a range of applications from single small buildings to community district heating networks. UTES (underground thermal energy storage), in which the storage medium may be geological strata ranging from earth or sand to solid bedrock, or aquifers. Conferences and organizations[edit] Use of STES for small, passively heated buildings[edit]

Masico Aguilar | La Escuela de los Saberes del Campo, el Buen Hacer y el Espíritu Colectivo… House in the Hill: What is a Passive Annual Heat Storage (PAHS) System? John Hait's book Passive Annual Heat Storage, Improving the Design of Earth Shelters provides a detailed description of a PAHS system, illustrates how to design and build one, and includes numerous warnings about how to avoid mistakes. For a summary overview of PAHS, see Umbrella Homes. To better understand how a PAHS system works and what it does, it is helpful to elaborate on each of the four words, Passive Annual Heat Storage. For those without a scientific background, some of the theory behind PAHS may seem somewhat complex, so I've tried to simplify the explanations. Passive: A properly functioning PAHS system should require a minimal amount of fossil fuels for heating and cooling, such as gas, oil, or coal. Annual: A PAHS heating and cooling system is influenced by the annual climatic conditions surrounding the house and thus never quite reaches a steady year-round operating state. Heat: Heat energy is a mysterious entity.

Construyendo la casa bioclimática Arquitectura en verde. Jornadas de Bioconstrucción. Valencia 04/04/08 Viviendas de estructuras suaves, que cuentan con zonas comunes orientadas al sur, paneles solares, poco hormigón y mucha madera. Así son las casas ecológicas E.PÉREZ VALENCIA La bioconstrucción es mucho más que instalar un panel solar en el tejado de casa, aunque puede empezar por ahí. Madera, piedra natural, barro cocido, corcho, cáñamo y balas de paja son sus materiales de cabecera. La cuidada elección de los materiales -algunos son poco habituales en las obras convencionales- y una mano de obra especializada -partiendo de los arquitectos encargados del proyecto- puede encarecer hasta un 15% el precio final del inmueble, aunque a la larga sale rentable. Pero no todos los arquitectos especializados en bioconstrucción coinciden en que es una técnica más cara. La primera barrera que hay que derribar es la de la conciencia. Modos tradicionales ¿Cómo se combina eso con la cada vez más escasa masa forestal española?
