FASUDIR stands for Friendly and Affordable Sustainable Urban Districts Retrofitting, an EU FP7-funded research project from around 2013-2016.cordis.europa+1
Project Goals
It aimed to mobilize Europe’s building retrofitting market to meet 2020 and 2050 energy efficiency targets by developing cost-effective strategies at the district scale. The focus was on balancing economic, environmental, and social sustainability through scalable interventions like energy-efficient tech from SMEs. This addressed urban typologies across Europe, prioritizing sequential retrofits for maximum impact.scienceportal.tecnalia+2
Key Outputs
The main deliverable was an Integrated Decision Support Tool (IDST), a software with a 3D interface for modeling districts and buildings. It helped stakeholders rank optimal retrofitting options, from off-the-shelf tech to new business models leveraging economies of scale. Validation occurred in diverse urban case studies, producing CityGML models for planning.b4l.ectp+1
Projected Impacts
FASUDIR estimated annual energy savings up to €4.3 billion if scaled EU-wide, plus 15% less construction waste and jobs for 444,000 people. It targeted improving life quality for about 11 million residents in retrofitted districts.[cordis.europa]
