Cagliari Smart Condominium, Italy

Case study leader

R2M and AXPO

The Via Bolzano 4 condominium was built in 1966 and has eight, four-room, 85 m² apartments.

It has an energy rating of G (the lowest possible). There is no central heating, only individual heating units with no energy monitoring or control systems.

The building currently has envelope water/air leakage and a maintenance/retrofit is scheduled by R2M Energy independently of the Lightness Project.

Given this planned renovation, there is the opportunity to retrofit and showcase a “smart condo” concept consisting of interventions like:

  • Formation of a Citizen Energy Community at the building-level.
  • Installation of 20kWp solar system on rooftop.
  • Change of energy supply contract to AXPO with new contractual options and flexibility.
  • Blockchain-enabled energy management.
  • Real-time analytics and data available to prosumers.

 

Additionally, aspects of the Smart Condo retrofit are being shaped for crowdfunding by project partner ENER2CROWD for publicity and citizen and businesses engagement.

Challenge

There is a lack of confidence and a proven track record on how to implement new EU energy regulations like the Directive (EU) 2018/2001 of the European Parliament that established the concept of energy communities, specifically the collective self-consumption of energy produced. However, showcasing this pilot site will send an important signal to the market and market actors.
