Lugo has had one of the zero-energy buildings at the forefront of Spain and Europe since mid-March: the Norvento Enerxía Innovation Center (CIne). The building, the new headquarters of the company specialized in renewables Norvento, will prevent the emission of more than 160 tons of greenhouse gases per year with a microgrid of combined renewable energies. Thanks to it and a design dedicated to energy efficiency, the building covers 100% of its needs without connection to the electricity and gas network.
Third newly built building in Spain to obtain the BREEAM certification in an exceptional degree, with which the most efficient constructions are recognized, the design signed by the Navarrese architect Patxi Mangado was inaugurated on March 19 after six years of work to shape it. From that moment, it will host the headquarters of the promoter company, the Galician Norvento, but not only that. Showcase of the technologies offered by the company, this center aspires to be an incentive for the industry and the company to row in favor of the energy transition.
” We want to send a message to the whole of the industrial and business sector: today it is possible to change the way in which they obtain and manage energy, in favor of greater efficiency, savings and competitiveness” . It was the message that the founder and head of the company, Pablo Fernández, wanted to launch at the opening ceremony, which was attended by the president of the Xunta de Galicia, Alberto Núñez Feijoo, and the European Commissioner for Action for Climate and Energy, Miguel Arias Cañete. Beyond words, the towering array of renewable technologies in the CIne building points the way to the energy transition.
With an area of 4,000 square meters and capacity for 200 workers, the construction in which 12 million euros have been invested leaves no loose ends to be completely autonomous, both in electricity, heat and cold needs. For this, there are many aspects that have been influenced. The first has been the design and implementation of an electrical and a thermal microgrid. Alongside them, a prominent role is played by a highly advanced storage system that combines electric batteries with thermal accumulation.
But before storing, comes capturing. In this area, the CIne center draws on three renewable sources. On the one hand, it exhibits the first wind turbine type nED100 to come into operation. The 400 Mwh per year that this turbine will provide will be accompanied by the 165 kWp photovoltaic panels that cover the roof of the company’s car park. In it, by the way, 5 points have been set up for the recharging of electric vehicles that could be extended to 28 to, with them, have the needs of 9 out of 10 vehicles of the company covered.
While the sun will provide 60% of the energy that the Norvento headquarters needs, the wind will do the same with 35%. From there to 100% there is still a small portion, 5%, which is delivered by a group of cogeneration based on recycled vegetable oil that starts operations in the absence of sun and wind.
This system also supports the thermal network deployed, in this case to respond to the company’s heat and cold demands. Two geothermal heat pumps to feed a radiant floor, as well as ventilation systems for the recovery of heat and cold are key pieces of this gear. However, much of the success at this point is also in energy efficiency, which has mediated all aspects of the design.
As if the above were not enough, there are more aspects that this construction takes care of to achieve the goal of zero energy. The orientation of the building, the thermal insulation, the entry of natural light and the reuse of gray water also have a place in this headquarters, which has not neglected the importance of the materials chosen. Sustainability and proximity have been two premises that have come into play and that are shown in the choice of material with which the building has been covered. This is none other than eucalyptus wood native to Galicia.
Galician raw material for a Galician company that, from this point in Spain, offers a whole showcase of sustainable construction. With him, this firm specialized in renewable technologies for the industrial and business sector is heading towards an expansion phase. So much so that the goal set for 2020 is to increase the turnover with which 2017 closed by 60%, which amounted to 42 million euros.
