1. Most Important Goals
- Formal experimentation curved load-bearing walls.
- Propose a bioclimatic housing typology that has a high ability to cool itself, only for its architectural design, and without mechanical devices.
- Stimulate the emotions of the occupants of the house, and variable perception of it, getting ever-changing architectural spaces, depending on the observer's position.
2. Architectural Solution
The house is situated in a privileged area south of the city of Cali, Colombia. The environment is tropical and very hot, and just generally running the breeze caressing the city of Cali, in the day.
For this reason, has proposed a special type of housing, consisting of three main bodies. The central zone is the area of distribution of housing, and separates the day area, the area at night. This communication provides vertical central housing and is responsible for generating a large volume of fresh air.
The areas of day and night ventilation have covered patios that ensure direct lighting, and generating a stream of fresh air, which will tour all the rooms of the house.
The property has several artificial lakes perimeter flood the lower gallery floor slab in order to increase evaporation, and falling temperatures.
3. Sustainable Analysis
1. Resource Optimization
1.1. Natural Resources. They take full advantage of resources such as 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. On the other hand, proper housing design, based on load-bearing walls, can be built with little supporting resources.
1.3. Resources recovered, reused and recycled.
The vast majority of housing materials may be recoverable (cover, woodwork, 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, insulation (made from discarded coffee bags), furniture, flooring and accessories.
2. Decreased energy consumption
The house is built with minimal energy consumption. The vast majority of materials and architectural elements used in the factory were made using a minimum 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 conventional energy (estimated to consume only 20% of that consumed a house in the same area and stratum). 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 (slabs, decks, carpentry, sunscreens, wooden beams, facilities, ...). 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 to generate the 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. 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 lighting (home automation system ensures that no artificial lighting can be used as long as natural lighting), which creates a healthy environment and provides the best quality of life possible to the 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 (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 perforated bricks 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 floors are made out of precast concrete.
2. Exterior finishes
Silicate paint. Tongue and groove boards and battens, teak wood, heat treated and dyed with vegetable oils.
3. Interior finishes
Paintings vegetables. Flooring tile porcelain tile. 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 tin plate coating (zinc).
Polypropylene water pipes. Polyethylene drainage pipes. Energy-efficient appliances. ...). Teak woodwork treated with vegetable oils. Cotton canvas awnings. Shading teak hardwood, treated with vegetable oils. All woods used have a certificate of origin with selective logging and ecological treatment (FSC).
5. Highlights Innovations
- Use of wood-cement block holes, and large format, for load-bearing walls of the building.
- Solar thermal Captors-longitudinal-horizontal, based on vacuum tubes.
- Use three shaded courtyards, which regulate and channel the flow of fresh air indoors.
- LED lighting, very low energy consumption by over 30% of the luminaries of the house.
