1960s Europe saw a large number of residential neighborhoods built to house those migrating from the countryside. Today, more than 50 years later, these suffer high levels functional, social, and technical obsolescence. In response this, University Seville developed Aura Strategy as an intervention methodology find global solutions issues in outdated neighborhoods. To provide visibility this aspect strategy, retrofit proposal presented article provides solution improve roofing buildings case study neighborhood (Polígono de San Pablo, Seville) analysis results terms energy financial savings for local residents. The show that population roughly 18,000 (in 2018), net savings, including retrofitting costs, ranging nearly 6.5 over 8.6 million can be made 20-year life cycle span. Likewise, obtained on reduction thermal loads indicate 72% decrease consumption, equivalent saving close 4,500 tons greenhouse gas emissions district entire time period, with consequent benefits impact air quality fight against climate change.
