Edificio Zaramaga (Vitoria). Prize for sustainable energy renovation at the 2016 GBCS Awards

The COP22 climate change conference that took place last year in Marrakech was the chosen scenario to announce the international winners of the fourth edition of the Green Building & City Solutions Awards 2016, in which seven buildings and three eco-districts were recognised for their innovative solutions. Spain was well represented with the Smart City Pamplona project receiving second prize in the Smart City category and the Edificio Zaramaga project in Vitoria winning the Sustainable Renovation Grand Prize category. The energy refurbishment of the Edificio Zaramaga building, a project from the studios Luz Espacio Arquitectos and IMV Arquitectos, is designed to reduce the energy consumption of this social housing block and guarantee the comfort of its inhabitants.

Situated at Cuadrilla de Laguardia nos. 2, 4 and 6 in the town of Vitoria-Gasteiz, the aim of the energy refurbishment project for this social housing block was to completely renovate its three buildings to achieve efficiency and provide them with the accessibility they lacked from street level to the upper floors. Action would only be taken on common elements and from the outside of the dwellings. For this, a thermal cladding was
installed on the entire building envelope, including the façades, roof and ground slab, to reduce energy consumption and CO2 emissions, in addition to eliminating thermal bridges. These actions, accompanied by the correct level of ventilation, would avoid condensation.

Following renovation, the social housing block is furnished with the necessary insulation and inertia features, air permeability control, regulated exposure to solar radiation and heat recovery ventilation for each dwelling. It thereby achieves thermal comfort taking into account the climate, the expected usage and seasonal variations combined with reduced energy expenditure. In short, the building enjoys a high level of energy efficiency that has resulted in the achievement of an A energy rating. Read more…
