Most Important Goals - Make new formal proposals, based on dynamic composition of walls of high thermal load. - Rehearse with new architectural systems of air cooling, using an architectural structure based on a central space on three levels and two wings of a single height. 2. Architectural Solution The house consists of three bodies twinned with irregular structure. The centerpiece is a three-storey covered patio that behaves like a greenhouse in winter, which heats the house, and in summer a generation of fresh air. Housing behaves completely different in winter or summer, and can be reconfigured easily to move from one state to another. In winter, the house becomes a big greenhouse, achieving the highest solar radiation in the south. In contrast, in summer, the windows close completely south, and housing is illuminated by indirect sunlight from the north and central covered courtyard zenith. 3. Sustainable Analysis 1. Resource Optimization 1.1. Natural Resources. They take full advantage of resources such as the sun (to heat the house), the wind, water and earth (to cool the housing), rain water (for watering the garden and flushing toilets), .... . On the other hand, has installed water saving devices on taps, showers and flush toilets. 1.2. Resources made. The materials used are maximized, thus avoiding possible waste through proper project and effective management (concrete, concrete blocks, wood, woodwork, plywood, paint, ...). On the other hand, proper housing design, based on load-bearing walls, can only be built without assistive devices (such as scaffolds, cranes, etc ...). 1.3. Resources recovered, reused and recycled. The vast majority of housing materials may be recoverable (cover, woodwork, glass, wood beams, girders, walkways, stairs, cabinets, wood coatings, sunscreens, health ...). On the other hand, has promoted the use of recycled and recyclable materials such as polypropylene water pipes, drain pipes of polyethylene, OSB plywood boards for interior doors, plywood panels for coatings, recycled glass countertop the kitchen, floors, stairs and windows, etc ... Finally, it has made extensive use of recovered materials (waste) and reused materials, such as wooden beams, furniture, flooring and accessories. 2. Decreased energy consumption 2.1. Construction. The house is built with minimal energy consumption. The vast majority of the materials used were manufactured using a minimal amount of energy. On the other hand, housing has been built with little supporting resources, and with very little labor. 2.2. Use Due to its characteristics bioclimatic housing has a very low energy consumption standard. The house is heated by a fireplace emissions and biomass. The hot water is generated by two solar thermal captors. The house is cooled by geothermal systems architecture and spraying water, and needs no mechanical conditioning, so no energy to cool. 2.3. Dismantling The vast majority of materials used can be recovered easily. On the other hand, housing is projected to have a high durability, as all components are easily serviceable housing. 3. Using alternative energy sources The energy used is of two types: solar thermal (solar captors for two ACS, and evaporation of water to air cooling), and geothermal energy (air refresh system taking advantage of low temperatures existing underground, in the galleries below forged sanitary housing). 4. Reduced waste and emissions Housing does not generate any emissions and does not generate any waste, except organic. Some of these household waste are used again to treat them accordingly (gray water for watering the garden). On the other hand, during the construction of the house just waste were generated. 5. Improving health and wellbeing All materials used are environmentally friendly and healthy and have no emissions that can affect human health. Similarly, the house is naturally ventilated, and maximizes natural light (artificial lighting can not be used as long as natural lighting), which creates a healthy environment and provides the best possible quality of life for building occupants . 6. Reduced price of the building and maintenance The house has been designed rationally, and most of its components are industrialized, eliminating redundant items, unnecessary or gratuitous, allowing construction to a greatly reduced price, despite the ecological equipment includes. Similarly, housing is almost maintenance: Regular cleaning and treatment of wood biennial vegetable oils. 4. Eco-friendly materials 1. Foundations and structure. Double-leaf walls and insulation. The inner leaf wall load is based on wood-cement blocks (Durisols) of 20 cm. thick, and large format. These blocks are filled with sand, or isolation, depending on their housing situation. The outer leaf is built using lightweight concrete panels of 7 cm. Inside there is a double sheet of hemp insulation layer of 6 cm. and a ventilated air space of 3 cm. The floor is made out of prefabricated concrete slabs. 2. Exterior finishes Silicate paint. Tongue and groove boards and battens, Ipe wood, heat treated and dyed with vegetable oils. 3. Interior finishes Paintings vegetables. Flooring tile porcelain tile. Double doors plywood board, beech plywood, and treated with vegetable oils. 4. Cover Roof garden, with an average thickness of 30 cm. of land. Pitched roof sandwich panel based consists of: top Viroc board (wood chips and cement) of 13 mm, bottom board of birch plywood 13 mm, and internal insulation hemp fiber 10 cm. thick. Based coating with a layer of rubber, and a coating of zinc sheet. 5. Others Polypropylene water pipes. Polyethylene drainage pipes. Energy-efficient appliances. Silestone kitchen countertops antibacterial. Walls and floors of high performance glass (anti-scratch, slip, easy cleaning, special screen ...). Iroko wood carpentry treated with vegetable oils. Cotton canvas awnings. Shading Ipe hardwood, treated with vegetable oils. All woods used have a certificate of origin with selective logging and ecological treatment (FSC). 5. Highlights Innovations - System refresh architecture, using a small central space on three levels. The cool air generated and maintained in the basement runs the lateral wings of the building, and rises again through the side wings (in reverse) to exit through the top central area (extracted by chimney effect). - System of de-wetting "Peltier effect", very low power consumption. The house has a perfect bioclimatic behavior, and in summer can offer, through the system architecture described above, temperatures around 24 º C. However, as the humidity is high, it is possible to lower the humidity level inside the housing by a simple mechanical system, and very low power consumption. This will improve the comfort level of occupants, without the need for mechanical air conditioning systems.
