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.

Maison en sacs de terre de 50 m2 pour 8700 euros Dans les pays occidentaux, le secteur du bâtiment est énergétivore et fortement émetteur de gaz à effet de serre. De plus, construire une maison engloutie les budgets des ménages. Le concept de maison en sacs de terre permet d'utiliser des produits locaux (terre trouvée sur place) et à un coût dérisoire. Les sacs peuvent être remplis de terre, de sable (ou autre matériau), en fonction des ressources disponibles localement. Un sac de terre ou de sable, cela ne bouge pas du tout (il existe plusieurs systèmes pour que l'adhérence des sacs entre eux soit totale : fil de fez barbelé, effet velcro etc.), la maison est très stable. Cette maison, un vrai bunker, est presque indestructible. En secteurs fortement déboisés (Haïti, Afrique subsahélienne etc.) le concept d'EcoDome apporte un avantage majeur : sa construction ne nécessite pas de bois (pas de charpente).

16. 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:

Eco-Dome: Moon Cocoon - Cal-Earth Building Designs The Eco-Dome is a small home design of approximately 400 square feet (40 sq. meters) interior space. It consists of a large central dome, surrounded by four smaller niches and a wind-scoop, in a clover leaf pattern. Learning and building an Eco-Dome is the next stage after building a small emergency shelter and provides hands-on learning experience in the essential aspects of Superadobe construction. The finished "very small house" is self-contained and can become a small guest house, studio apartment, or be the first step in a clustered design for community use in an Eco-Village of vaults and domes. Built from local earth-filled Superadobe coils (earth stabilized with cement or lime).Tree free.Maximum use of space through alternative options. The Blueprints for this design are approved and built in Hesperia City and San Bernardino County, California, as well as other regions nationally and internationally. Note:

Ecuador Commons Dream Green Home Plans 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]

Earthbag House Plans | Small, affordable, sustainable earthbag house plans 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.

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 :

Découvrez la maison bioclimatique enterrée à 10 000 € !!! La maisonnette - matériaux naturels, super-conomique, et autonome eau douce énergie (eau chaude et électricité) - cabine douche (500 euros), - lavabo (300 euros), - WC (300 euros - Possibilité d'utiliser également des toilettes sèches). + tuyauteries (200 euros). - Pour l'eau chaude : chauffe-eau solaire : 2000 euros, hors pose. Total du "mobilier eau" : 1600 + 2000 = 3600 euros. Eau douce : récupération de l'eau de pluie (mini écodome avec bâche réserve-plastique interne). L'ONU, l'armée et les ONG humanitaires utilisent ces réservoirs-bâche très résistants. En sur-élevant le réservoir grâce à des sacs de terre, pas besoin de pompe pour alimenter la maison, la circulation de l'eau se fait par gravité. La bâche étant complètement fermée, sans entrée d'air, et complètement opaque aux rayons solaires, la conservation de l'eau douce est très bonne. En France, la consommation domestique par habitant est de l'ordre de 137 litres d'eau par jour. Chauffe-eau solaire : Eaux usées : - Option 1 : toilettes sèches : compostage, etc...
