Most Important Goals - Make a house a very high level bioclimatic that lets you keep cool in summer, despite the high external temperature (50 º) in the province of Cordoba. - Experiment with new types, to give a home with great natural light, and thermally self-regulating whole year, without mechanical or warm soda. - Perform a low-cost housing and low maintenance. 2. Architectural Solution The house is arranged over three floors. The basement houses a multipurpose main hall. The ground floor houses the rooms of the house: lounge, kitchen, bedrooms and bathrooms. The first floor houses a bedroom and a lounge for guests. It has a multipurpose room located in the basement to store a large bag of fresh air (which rise and walk the entire house, cooling as it passes). Similarly, the ground floor and first floor are hollow to accommodate a central courtyard. The first floor has the rooms on the south side to the solar access to housing through the central courtyard. The covered patio is essential for the proper functioning bioclimatic and housing that allows it to cool in summer and in winter to keep warm. In summer the central courtyard and overhead lighting provides housing. The outside temperature is so high that it can illuminate the housing through conventional windows (in fact, the windows should be almost closed all summer). Therefore, the light enters the housing through the central courtyard, reflecting off the walls and interior mirrors and reaching the basement. The two existing solar chimneys on the patio is heated by solar radiation and create an air suction force. On the other hand, in the basement of the house creates a big bag of fresh air that rises and is sucked out. This will create a flow of air inside the house, through the central courtyard, covering the entire house, and cooling in its path. That is, the large patio covered ventral allows the home is well lit inside, but without heating. Solar radiation enters the housing at the top of the patio and warms the air. But this hot air immediately escapes through the outer solar chimneys, and draws fresh air from the basement. On the other hand, we must bear in mind that in winter the temperature of Cordoba can be very low, and need to enter the building as much direct sunlight. For this reason the housing is elongated, allowing the existence of large windows on the south side. Housing thus perfectly heated greenhouse. In summer, however, the windows are covered by means of some exterior shutters, preventing it from solar radiation, and therefore that the house warm. 3. Sustainable Analysis 1. Resource Optimization 1.1. Natural Resources. They take full advantage of resources such as the sun (to generate hot water, and provide natural lighting throughout the interior of the house), the breeze, the land (to cool the house), rainwater (water tanks reserve for garden irrigation and consumption), vegetation (for the garden, gardens and green roof) ... .. On the other hand, we have installed water saving devices in faucets, showers and tanks housing and treatment systems and naturalization of gray water and rainwater for mineral water suitable for consumption. 1.2. Resources made. The materials used are maximized, reducing potential waste through proper project management and effective (concrete panels, concrete blocks, wood paneling, wood-cement panels, bamboo panels, ceramic tiles, woodwork , sandwich panels, ...). 1.3. Resources recovered, reused and recycled. The vast majority of building materials can be recovered (flooring, woodwork, glass, wood beams, girders, deck, 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, polyethylene, chipboard, insulation made from recycled paper towels aircraft, panels, recycled plastic recycled glass, recycled panels for kitchen countertops and floors, etc ... 2. Reduced energy consumption 2.1. Construction. Housing has built and renovated with minimum energy consumption. The materials used were manufactured with a minimum amount of energy. 2.2. Use Due to their bioclimatic characteristics, the home has a very low power consumption. The house is heated by the greenhouse effect, heat emitted by the occupants and, just possibly, a chimney of biomass. Hot water is generated through the solar thermal sensors built into the south face of the whole. The house is cooled by a geothermal underground architectural system, and needs no mechanical conditioning system, so no energy. 2.3. Dismantling The vast majority of materials used can be easily recovered for reuse in the construction of another building (flooring, woodwork, glass, wood beams, girders, deck, walkways, cabinets, wood coatings, sunscreens, pergolas heather, health, ...). 3. Use of alternative energy sources The energy used is of two types: solar thermal (solar captors to produce the ACS) and geothermal (architectural system to cool the air, taking advantage of existing low temperatures underground in the tunnels underneath the house). 4. Reduction of waste and emissions The property does not generate any emissions, nor generate any waste, except human waste. 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 maximizing natural lighting, creating a healthy environment and provides the best possible quality of life for its occupants. 6. Reduced price of the building and maintenance The house has been designed in a rational way, and most of its components are industrialized, eliminating unnecessary items, unnecessary or gratuitous, allowing construction to a greatly reduced price, despite the equipment that incorporates ecological. Similarly, housing is almost maintenance: regular cleaning, and treatment of wood biennial vegetable oils. 4. Bioclimatic Characteristics 1.1. Heat Generation Systems The house is heated by itself, in two ways: 1. Avoiding cool: Due to its high thermal insulation, and having large glass surfaces just to the south. 2. Due to its careful and special bioclimatic design, and perfect NS orientation, housing greenhouse is heated by solar radiation and direct, and remains hot for a long time, due to its high thermal inertia. 1.2. Fresh Generation Systems The house cools itself in three ways: 1. Avoiding heat, providing most of the glass surface just to the south and east, providing sun protection for the direct and indirect solar radiation (a type of protection different for each of the holes with different orientation), and providing isolation appropriate. 2. Cooling through a cooling system architecture of air through underground galleries. Thus, in the basement of the house holds a large bag of fresh air of reserve that runs throughout the house and cools as it passes. On the other hand, due to high thermal inertia of the building, the accumulated fresh overnight stays for nearly all the next day. 3. Evacuating the hot air inside the house through two solar chimneys. Solar radiation heats two large metal chimneys located on the covered patio. When heated the fireplace warms the air inside, so it rises and goes outside. This creates a suction that draws air from inside the house, and makes the air rise and cool the basement along the entire home, cooling your step. The large patio covered ventral (along with the architectural study of housing) housing permits perfectly lights inside, but also prevents hot. Solar radiation enters the housing at the top of the courtyard and through several mirrors, lights up the whole inside of the house. At the same time, the solar radiation heats the air that is in the top of the central courtyard. But this hot air immediately escapes through the outer solar chimneys, and draws fresh air from the basement. 3. Storage systems (heat or cool) The heat generated during the day in winter accumulates on the floor slab and the concrete load-bearing walls, keeping the house warm at night. Similarly, generated during the cool summer night up in the floor slab and the load-bearing walls, keeping the house cool during the day. The roof garden high thermal inertia, reinforces this process. 4. Transfer systems (heat or cool). The heat generated by natural radiation emissions and is distributed in the form of hot air throughout the house through the courtyard. Similarly, the heat stored in the load-bearing walls is transmitted to the radiation side rooms. On the other hand, the cool air generated in the underground galleries are spread over the house across the courtyard and through a set of grids spread over the slab of the house. This air flow cools every room of the house. 5. Natural ventilation The ventilation of the building is continuously and naturally through the very walls of enclosures, allowing adequate ventilation without energy loss. This type of ventilation is possible because all materials are breathable (ceramic, natural insulation, concrete panels, wood-cement panels, eco-friendly paints). 5. Most important innovations - Getting a house can stay cool all summer without mechanical refresh, even though the outside temperature is very high (around 50 ° c.). Of course, the home has a high level of natural lighting, lighting capable of providing needed housing occupants from dawn to dusk. - Getting a home that does not require mechanical heating systems in winter, and is capable of regulating heat at an appropriate temperature throughout the year. - Design an architectural structure for extracting air from the home for "chimney effect" through an internal covered courtyard, which allows the home is well lit inside, but also prevents hot.
