Owner approach of sustainability
Buildings pollute*.When you build them, the contamination is produced by manufacturing materials and production of rubble.And when you use them, the contamination is produced by the energy to live in them.Our proposal is to reduce pollution by 50% in manufacturing, 50% of waste production, and 75% energy for heating or cooling.Therefore, we’ll recover techniques and materials from traditional architecture, and low-tech systems without sophisticated devices that use to get broken.Not only for environmental issue, but also because we would live much better and costs nearly the same.And if this is repeated widely, cities will be more friendly and nice.For this reason, the project is a prototype to reduce the vulnerability of human environments to climate change. It establishes measures to reduce the production of CO₂ by 50 %, and therefore, if all new buildings would be made in this way, the building sector and energy consumed by this cease to be an important factor in increasing the global temperature (the construction industry produces 17% of CO₂ emissions in Spain).The experience of this project has an added value for the EU since it is directly applicable to the Mediterranean region.It is also a model of efficient construction to achieve the objectives of the EU 20/20/20 strategy, which requires all public buildings to achieve nearly zero consumption from December 31, 2018. At this moment, the nearest qualification in EU is Energy Class A rating. This building would be the first example of collective housing building with Energy Class A rating at the Balearic Islands.*In the Balearic Islands, the energy consumption for buildings pollutes more than all transports (airplanes, cars, trucks, ships, etc.).
The project is understood as a territory map of resources, and is the result of a comprehensive study of program and site conditions, as summer prevailing winds, solar orientation, rainfall, geotechnical, morphology and urban context, local regulations, reusable waste and local materials, available industries, building tradition and crafts, available clean energy, full-cycle water management, ecological footprint reduction, and dwelling typologies adapted to the needs of potential residents.Traditional architecture has been a constant reference, not as shape, but as a way of working from economy of means and what you have available. These are the glasses to watch closely. With them, we look for what can we use on the island: Junipers, which were used to build frameworks, right now are protected. The sandstone quarries are exhausted and there is little straw used for livestock. So, we have just what comes from sea meadows, boats, and building pallets that remain on the island because of the cost of boarding back.So we propose a change of paradigm:“Instead of investing in a chemical plant located 1.500km away, we invest the same budget to local unskilled labor, which should extend the Neptun grass to dry under the sun and compact it in pallets, achieving 15cm of insulation in roof. Moreover, it turns out that sea salt acts as natural biocide product and is completely environmentally friendly.”The rest of the material used in this project comes from a market study based on their cost, the embodied energy, and the adaptation to comfort levels required to achieve a passive house.

POSIDONIA OCEANICA INSULATION
IBAVI + UIB + FERROVIAL
Thermal and acoustic insulation composed of dead leaves of Posidonia Oceanica. The use of Posidonia in building work must be done with extreme caution, and their use should be limited to areas where the accumulated volume exceeds the amount necessary to maintain the balance of coastal dune ecosystem. The extraction is always carried by the state or regional bodies that manage this heritage, meeting protocols and legislation, and never by individuals or private companies On the beach, a loading shovel controlled by technicians Environment Consell de Formentera provide the necessary material to the trucks that transport the bulk posidonia to the site of the works. This project complies with all protocols to avoid the environmental impact of the collection of Posidonia on the beaches, as indicated in the authorization by the Service of Protected Species of the General Directorate of Natural Medi, Environmental Educació, i Canvi tprint, and the Ministry of the Environment, Industry and Energy of Formentera. Tests have been conducted thermal insulation in collaboration with the department of applied physics from the University of the Balearic Islands (UIB), obtaining results above forecast.
100% acceptance of this product.
In a town of about 800 inhabitants approx. at the island of Formentera. The site is part of BIC-Esglèsia of Sant Ferran, and is protected by the subsidiary rules (level 1), establishing mandatory aesthetic criteria (width max. Windows, finishes, etc.).
Land plot area
It has been decided not to build an underground parking for the following reasons: 1. Statistically, parkings involve 30% of CO2 emissions associated with the construction of a building, due to excavation works and embankments. 2. They hinder the execution of load-bearing walls and structural system housing. Generally they lead to arcaded structures that increase the stresses on the ground and eliminate the possibility of working with lime concrete foundation, whose resistance is of the order of 5 kN. 3. They take the floor free plots, preventing its use as a garden or crop itself. 4. In the case of social housing, public ownership, building parking lots involves allocating public funds to shelter cars instead of accommodating people.
Therefore, the construction of underground parking is discouraged when urban conditions permit it.
