• Resumen

  • The Universidad de Valladolid (UVA) has built a 3,500 m2 R&D + i (Research & Development + Innovation) building on the Soria University Campus, for R&D + i activity and training. It is designed to adapt to educational changes. The UVA has been investigating how to improve the sustainability of its new buildings for the last ten years or so. In the Soria building, we have also tried to improve the urban connections between its location – in the outskirts of Soria – and the same small town of around 39,000 inhabitants. With this approach, the new building covers three objectives: to achieve a nearly zero-energy building (NZEB) performance; to make it functionally adaptable to an educational and changeable use; and to improve the nearby urban landscape. The three objectives must coordinate with each other to achieve a coherent and harmonious solution. Three strategies have been used for obtaining the NZEB objective. They are: (a) multiple design solutions that minimise energy demand, (b) the incorporation of selected technologies with strict energy efficiency criteria and (c) the generation of on-site energy. For this, the external conditions and the location have been studied and assessed, to make the site its own energy resource (through geothermal energy, solar wall, and photovoltaic production). The dynamic simulation carried out with Design Builder version 5 showed a reduction in final energy consumption of 84% compared to the current requirements of the Spanish CTE regulation, and 81% in non-renewable primary energy, which represents an 86% reduction in emissions of CO2. Its energy certification is A, and it is being evaluated through the international LEED and national VERDE-GBCe certifications.
