1. Most Important Goals
- Make new formal proposals, based on dynamic composition of walls of high thermal load.
- Designing a house with a high degree of industrialization.
- Design a unique home design for mass promotion.
- Demonstrate that the heating system more economical and effective for a bioclimatic house is based on electric radiators, night rate.
2. Architectural Solution
The aim is to make a prototype of housing, with unique design and high added value for mass promotion. The first stage will be built 4 houses in a residential area on the outskirts of Barcelona, but the goal is to build the prototype in several different places of the Spanish geography.
The house comprises three levels. The ground floor is the living area, first floor the bedrooms of children, and the top floor bedroom-living parents.
A covered patio runs through the three-storey house from top to bottom, giving it vertical communication, and allowing it to cool in summer.
The heating system chosen is based on electric batteries nightly rate. By having a high level structure of bioclimatic housing have little need for energy consumption. In fact consume only 50% of the energy of a conventional house of the same surface. On the other hand, choosing night rate, the cost of electricity is reduced to 50%. By combining both worlds, what you get is a final price of electricity by 25%. What makes it the cheapest energy available. Similarly, this increases the "quality" of electricity, and that makes 4 times more effective. Finally, the electric heating is the safest, cleanest, and needs no additional spaces dedicated or expensive facilities.
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, reducing potential waste through proper project, effective management, and above all, because each component of the building has been individually built at the factory.
1.3. Resources recovered, reused and recycled.
All building materials may be recoverable, including all elements of the structure. Thus, can be easily repaired, and reused in the mime building, or in any other.
Likewise, it has boosted the use of recycled and recyclable materials.
2. Decreased energy consumption
The building has been constructed with minimal energy consumption. The materials used were manufactured with a minimum amount of energy, since all components are factory, with complete control. On the other hand, the building is constructed with very few assistive devices, being fully industrialized.
Due to its characteristics bioclimatic housing has a very low energy consumption standard. The house is heated greenhouse and a heating system based on electric batteries, with nightly rate. The hot water is generated through solar thermal captors. The house is cooled by geothermal systems architecture and spraying water, and needs no mechanical conditioning, so no energy to cool.
The vast majority of materials used can be recovered easily. On the other hand, the building is designed to have indefinite durability, since all the building components are easily recoverable, repairable and replaceable.
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.
Two sheets of drywall and insulation. The inner leaf is the load-bearing wall of reinforced concrete 15 cm. thickness (with high thermal inertia). The outer sheet is lightweight precast concrete of 6 cm. Inside there is a double sheet of hemp insulation layer of 5 cm. and a ventilated air space of 3 cm. In some parts of the facade has been replaced the outer concrete panel, a ventilated façade based Ipe wood treated with vegetable oils. 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. Parquet floorings bamboo plywood. Double panel doors bamboo 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. 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
- Triple skin on the south facade cladding (Camera-based concrete panels, sliding shutters, windows protected inner canopies). This triple skin allows the maximum capacity regular sunscreen housing, and capacity of solar bioclimatic.
- Prefabricated system of structure based on double wall (wall charge and wall covering), which allows total removal of the dwelling in order to facilitate the repair or reuse of all components, including the structure itself.
