1. Most Important Goals
- Conduct a home with unique design, perfectly integrated into the environment and the particular conditions of the site.
- Make new formal proposals, based on dynamic composition of walls of high thermal load.
- Projecting a high bioclimatic housing, to behave well both at low temperatures, such as high temperatures.
- Demonstrate that the heating system more economical and effective for a bioclimatic house is based on electric radiators, night rate.
2. Architectural Solution
The shape and orientation of the site has inspired the peculiar form of housing. The triangular plan allows, on one hand, a large area of southern exposure, and outstanding panoramic views to the north.
To optimize the functional use of the triangle attached two volumes have been flown, allowing side stays homer on the first floor to protect them from solar radiation in the morning and evening, and provide them with better views.
The central area of the triangle is the central hall of the house, connecting the north end to the center of the south face. Thus, you can enjoy the view from the entrance door of the house.
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, cement 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 can be recovered (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 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
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.
Due to its characteristics bioclimatic housing has a very low energy consumption standard. The house is heated by greenhouse gases and solar radiant floor heating. The hot water is generated through solar thermal captors. The house is cooled by geothermal architectural systems, mechanical systems and requires no packaging, 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, gateway, staircase, ceramic tile, windows, shutters, doors ..). 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 underfloor heating and 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 the floor slab of the house).
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 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. Basalt Tile Flooring. Double doors plywood board, beech plywood, and treated with vegetable oils.
Roof garden, with an average thickness of 30 cm. of land.
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
- Radiant floor heating, energy-efficient, since only requires three solar captors, to provide the necessary hot water for home heating, and the ACS.
