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.

Habiter-Autrement What is a Passive Annual Heat Storage 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.

Ecuador Commons PopUp House: une maison passive et 100% recyclable montée en 4 jours Une start-up d’Aix-en-Provence a créé la « maison passive » : Pop-Up House n’est pas chère et recyclable, et se construit en quatre jours seulement. Deux prototypes de cette maison préfabriquée ont été réalisés avec succès et attendent leur commercialisation, prévue début 2015. Vous voyez ce qu’est une tente 2 Seconds de la marque Quechua ? Et bien la Pop-Up House se base quasiment sur le même concept à une différente échelle : réaliser l’ensemble d’un bâtiment (sol, murs, plafond) par assemblage de blocs isolants séparés par des lames de bois. Il vous suffit pour cela de vos bras et d’une perceuse : la maison se monte comme du Lego. Cette maison est passive : elle repose sur un concept de construction très basse consommation, basé sur l’utilisation de l’apport de chaleur « passive » du soleil, sur une très forte isolation, sur l’absence de ponts thermiques, sur une grande étanchéité à l’air ainsi que sur le contrôle de la ventilation. Voici la vidéo du concept :
