1. Most Important Goals
- Make new formal proposals, based on dynamic composition of walls of high thermal load.
- Projecting a high level bioclimatic housing, without heating or mechanical conditioning.
- Demonstrate that the heating system more economical and effective for a bioclimatic house is based on electric radiators, night rate.
2. Architectural Solution
The formal structure of the house reflects the worship that surrenders to the use of load-bearing wall in the composition of buildings with bioclimatic high. The load-bearing wall greatly increases the thermal inertia of the building, and is able to store heat or cool, and maintain a stable temperature inside the building.
The house consists of three bodies twinned with irregular structure. The centerpiece is a three-storey covered patio in winter behaves as a greenhouse-heated housing-and in summer a generation of fresh air.
Each of the lateral bodies has a covered garden courtyard, which provides a favorable microclimate adjacent to the rooms.
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 large greenhouse, getting the maximum 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 house), rainwater (for garden irrigation and flushing toilets), .... . On the other hand, we have installed water saving devices in faucets, showers and flush toilets.
1.2. Resources made. The materials used are maximized, avoiding possible waste through proper project, and effective management (concrete, cement blocks, wood, woodwork, plywood, paint, ...). On the other hand, the correct design of housing, based on load-bearing walls, can be built with little supporting resources (such as scaffolding, cranes, etc ...).
1.3. Resources recovered, reused and recycled.
The vast majority of housing materials can be recovered (pool, carpentry, 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, polyethylene, chipboard OSB for interior doors, plywood boards, coatings, recycled glass for countertops the kitchen, floors, steps, and windows, etc ...
Finally, it has made extensive use of recovered materials (waste) and reused, such as wooden beams, furniture, flooring and accessories.
2. Reduced energy consumption
The house was built with minimum energy consumption. The vast majority of the materials used were manufactured using a minimum amount of energy. In addition, housing has been built with hardly any assistive devices, and with very little labor.
Due to their bioclimatic characteristics, the home has a very low conventional energy. The house is heated by a fireplace emissions and biomass. Hot water is generated by two solar thermal captors. The house is cooled by geothermal architectural systems and spraying water, and does not need conditioning mechanical systems, so no energy to cool.
The vast majority of materials used can be recovered easily (once the life of the building) to be reused in the construction of another building (roof, wooden beams, walkways, stairs, ceramic tiles, windows, shutters, doors ..). On the other hand, housing is projected to have a high durability, as all housing components are easily repairable.
3. Use of alternative energy sources
The energy used is of two types: solar thermal (solar captors for two ACS, and evaporation of water to cool air) and geothermal (air refresh system leveraging existing low temperatures underground, in the galleries below forged sanitary housing).
4. Reduction of waste and emissions
The property does not generate any emissions and does not generate any waste, except organic. Some of these household waste are used again suitably treated (gray water for watering the garden). On the other hand, during the construction of the house hardly generated 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 maximizes natural light (artificial lighting can not be used as long as natural lighting), creating 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 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. Eco-friendly materials
1. Foundations and structure.
Walls of two leaves and isolation. The inner leaf wall load is based on blocks of wood-cement (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 with lightweight concrete panels of 7 cm. Inside the double leaf is a layer of hemp insulation 6 cm. and a ventilated air space of 3 cm. The floor is made out of prefabricated reinforced concrete panels.
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. Stone Tile Flooring Sirius polished, ground floor, and wooden birch plywood, and treated with vegetable oils, on the first floor. Double panel doors plywood, beech plywood, and treated with vegetable oils.
Roof garden, with an average thickness of 30 cm. of soil. Pitched roof sandwich panel based includes: top Viroc board (wood chips and cement) of 13 mm, bottom board of birch plywood 13 mm, internal insulation of hemp fiber of 10 cm. in thickness. Based coating with a layer of rubber sheet and a coating of zinc.
Water pipes made of polypropylene. Polyethylene drainage pipes. Energy-efficient appliances. Silestone kitchen countertops antibacterial. Walls and floors of high performance glass (anti-scratch, anti-slip, easy cleaning, special screen, ...). Iroko wood carpentry treated with vegetable oils. Cotton canvas awnings. Shading of Ipe hardwood, treated with vegetable oils. All woods used have a certificate of origin with selective logging and ecological treatment (FSC).
5. Most important innovations
- Incorporation of covered patios, as temperature stabilizer system, both in winter and summer.
