Social housing complex, Similaun street, Bolzano

The municipality of Bolzano has carried out a complete refurbishment of social housing apartment complexes. The inteventions were carried out within the Sinfonia research project and included: energy retrofitting, the installation of mechanical ventilation systems, and geothermal heating, photovoltaic and solar thermal systems. The Sinfonia energy retrofit involved more than 300 apartments in 5 different building complexes for a total area of 53.000 m². The details below refer only to the building complex in the Similaun street.

The role of Eurac Research

As part of the SINFONIA project, Eurac Research coordinates the activities relevant to the Bolzano district. In this building our researchers have provided support in relation to the insulation interventions, analysis of the solar potential for the installation of thermal and photovoltaic panels on the roof, district heating simulations, post-refurbishment energy consumption monitoring.

Implemented technologies

Insulation of the entire envelope, facades and floors, solar thermal and photovoltaic panels on the roof, decentralized controlled ventilation system (with heat recovery), replacement of gas-fired boilers by sub-district heating plant connected to the grid
