Bolzano

Since 2005, Bolzano (Italy, 100,000 inhabitants) has developed an ambitious investment plan for large scale urban refurbishment in collaboration with both public and private stakeholders. The work undertaken in SINFONIA is part of this plan, and aims to achieve 40% to 50% primary energy savings in the demo sites and to increase the share of renewables in the district of Bolzano SW (South West) by 20%

BUILDING REFURBISHMENT

 

37,000m² of social housing from the 50s-70s will be retrofitted to achieve high energy performance and improve interior comfort while ensuring cost effectiveness and minimal impact on tenants. Measures include:

 

  • Building envelope insulation;
  • Integration of renewable energy sources for electricity, heating and domestic hot waterSolar PV panels; 
  • Additional storeys using innovative timber construction technologies.

 

 

DISTRICT HEATING & COOLING

 

The district heating & cooling network will be extended and optimised to reduce both the CO2 and the nitrogen equivalent emissions. Measures include:

 

  • Real time monitoring and forecasting of peak loads and energy demand;
  • Hybrid hydrogen/methane backup system;
  • Study on recovery of wasted energy from local industrial park.

 

ELECTRICITY GRID

 

Bolzano will implement an Urban Service-Oriented Sensible Grid (USOS-grid) system in the South West district for improved energy distribution control. Measures include:

 

  • Recharge points for vehicles and bicycles;
  • Meteorological stations for local climate condition monitoring;
  • Smart retrofitting of the public lighting system.

How to monetize the impact of Smart Cities projects

As cities have become key actors of the energy transition, assessing the benefits of Smart City projects only in terms of energy savings appears to be limited to encompass the real effectiveness of these investments.
