1. Most Important Goals
- Conduct a home, including medians, high and bioclimatic sustainable level, in a small town.
- Making a building with two interconnected houses, with a high level of natural lighting, despite the small surface of the facade.
2. Architectural Solution
The site is irregular, and has great depth buildable. For this reason it has provided a large central courtyard covered, in order to provide the central building overhead lighting capable of illuminating the core of the building.
This central courtyard separates the day area of the sleeping area, and serves to connect the housing with roof garden.
He has made extensive use of glass in the interior of the house (floors, stairs, walls ...) in order to provide the highest level of natural light, despite the small size of the south facade.
3. Eco-friendly materials
1. Foundations and structure.
Double-leaf walls and insulation. The inner sheet is made out of wood-cement blocks (Durisols) of 20 cm. thick, and large format. The outer leaf is built with Trespa panels of 13 mm. thick, natural stone veneer. 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. Trespa panels battens (Pacific Board) of 13 mm. thick and polished natural stone plates of 35 cm. * 200 cm., 4 cm. thick.
3. Interior finishes
Paintings vegetables. Floors of polished marble, parquet and birch plywood, treated with vegetable oils. Double doors plywood board, beech plywood, and treated with vegetable oils.
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.
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. Internal blinds Japanese cotton canvas. Shading Iroko solid wood, treated with vegetable oils. All woods used have a certificate of origin with selective logging and ecological treatment (FSC).
4. Highlights Innovations
- Solar underfloor air conditioning (hot and cold) from two separate zones, powered by solar thermal captors.
- System of de-wetting "Peltier effect", very low power consumption. The house has a perfect bioclimatic behavior, and in summer can offer, by itself, 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.
- Control system of direct sunlight in winter, through a mirror system located in the central courtyard of the building.
