In several areas around Pamplona, Spain, a largescale renovation programme is slashing the energy costs and emissions of hundreds of existing buildings and breathing new life into old neighbourhoods.
70 percent of the buildings in the Txantrea neighbourhood in Pamplona, Spain, were built during the 1980s, making age-related energy loss a common issue in many homes. The problem was brought to the attention of the government of Navarre, resulting in the creation of the Efidistrict project. With an aim of improving energy efficiency by renovating the ageing buildings, the project also served to promote similar transformations in other municipalities of Navarre.
The impact of this large-scale renovation effort in Pamplona is unmistakable. Once rundown, the 23 public housing buildings – all of them between 40 and 70 years old – glisten like new. But for the residents of almost 600 homes, the improvements run far deeper than the attractive new façade. A new thermal envelope that includes 10 cm of ROCKWOOL external façade insulation has significantly lowered energy consumption and costs, and improved acoustic comfort inside.
In addition to taking steps to dramatically reduce energy consumption, the use of fossil fuels have been replaced with renewable energy sources such as biomass.
