Energy-intensive building

The building is intended to applied research in the fields of Biotech, Nanotech and new technologies. In one approach to the place where the building is located, the interest is found to activate the center of the block, linking it to the open space of the street and providing passage through the building, to convert the existing pubic space in a meeting point. The presence of the building intended to link, but not figuratively, with the existing built front, proposing, abstractly, a continuity in the skin texture of the traditional city. We propose a building conceived from separate components that can be produced industrially and with similarities with the place, in order to get a body built very flexible for its subsequent uses, including its deconstruction. The architecture has been designed to act as an interface or balancing factor between the climate conditions outside and inside, not a watertight barrier but as a membrane that filters and exchanges with the surrounding conditions. The facade has an efficient envelope that responds to all the physical requirements of the building - structure, screening, natural light, insulation and services.

Air conditioning ducts descend from the facilities placed on deck facade.

    According to the specific project of solar thermal justification, the building does not require system thermal solar collector to have a connection to the network of "District Heating" "Cooling" (Districlima) For the calculation and design of solar gain has been consider the following features: · Location and location of the building · Situation of solar collectors · the occupation of the building is planned for 150 people and use agrees with the aforementioned activity in chapter 2.1.Un photovoltaic system connection network, is one that harnesses the sun's energy to transform it into electrical energy that is transferred in the conventional network because it can be consumed by any user connected to it. The large-scale extension of these applications has necessitated the development of a specific engineering that allows, on the one hand, optimize design and operation and, on the other, assess the impact on the entire electrical system, having always cure systems integration and respecting the architectural and ambiental environment. The high reliability and long life of photovoltaic systems must be highlighted. On the other hand, its almost maintenance-free and have a great simplicity and ease of installation. Also, the great modulation of these facilities can propose projects in stages and adapt to the needs of each user, either according to their needs or economic resources . The PV array format by a series of connected modules together, is responsible for transforming the sun's energy into electricity. This energy, but is in the form of direct current and has to be transformed by the inverter into alternating current for coupling to the conventional network. So for photovoltaic modules continues to generate a current proportional to the solar irradiance impinging upon them. This will bring the inverter is running, and using power technology, makes alternating current at the same frequency as the electrical network and thus is available for any power generated user. And measured by a corresponding counter, will sell the distribution company as stated above Royal Decree. In an installation they can be used several inversors, each with its photovoltaic generator independently. This gives a great modulation system both for future extensions to perform maintenance, etc. INVERSORS The power of the proposed facility in running 7.84 kW AC is above the minimum marking of regulations. The 7,27kW photovoltaic generator will be installed to cover as indicated by the high plateau, trying to get the best integration architectural therein, with minimal loss of performance of the system. As shown, the high plateau will integrate with the same slab, since the characteristics of this permit: insulating and draining fotovoltaïcs modules (BIPV) for covered , protection of waterproofing protection of the waterproofing membrane waterproofing membrane protection against intemperie. The conventional network connection will be implemented in phase with investors feeding each fases. On the other hand, it is necessary to include to install an energy meter input to the photovoltaic system in order to deduct from the energy generated, of which this will be able to consume from the conventional net.

Urban environment

The building in the neighborhood Understanding 22 "arroba" as an overlay network that energize the pole of the city, you need to think in a building that acts as a new way to link to existing networks and also helps to generate value in this shared system. In the neighborhood several specific networks converge generically could identify how; network of companies that generate knowledge and economic value, MOBILITY network in terms of communication and transport, energy network linked to the distribution of different production systems and finally centralized network services to boost activity in the neighborhood. The building / the place A further approximation to the place where the building has to be located, we appreciate the need to activate a center island, until now residual, linking the open space of the street and simultaneously promoting the passage of pedestrians through it, to turn this empty space in a home for people meeting the very middle of the city. The arrangement on the ground floor of the center bar, closely linked to the public space, reinforces this intention. In this regard, we propose a massing that is itself a great porch that serves as shelter for uses related to this meeting place, and at the same time to open the maximum visual center line to the street island. The presence of the building intended to link to, but not figuratively, with the existing built front abstractly proposing a continuity in the skin texture of the traditional city. FLEXIBLE BUILDING, FUNCTION, SURROUNDING Our project proposes a very flexible built body, to the extent that has an efficient envolvent that responds to all the physical requirements of the building - structure, screening of natural light, insulation and provides services - so that indoor plants are completely diaphanous and suitable for any functional adaptation.
