Energy Requalification of a 1970s Condominium in Trento with Superbonus 110%

In the center of Trento, our studio completed an important energy requalification project on a condominium built in the 1970s, taking advantage of the Superbonus 110% incentives. This intervention was designed to combine energy efficiency, residential comfort, and respect for urban aesthetics, given the proximity to a neighboring structure that was not part of the works.

Project Details

The condominium, developed over seven floors above ground plus one basement level, houses garages, cellars, and a thermal power station in the basement, offices on the ground and first floors, and 18 apartments spread from the second to the seventh floor. The load-bearing structure is made of reinforced concrete with double brick wall cladding and a partially insulated concrete roof.

Interventions Made

To improve energy efficiency and guarantee a significant improvement of at least two energy classes, we carried out the following interventions:

1. Thermal Insulation of the Facades:
   • Creation of an EPS thermal coat with a thickness of 16 cm on all facades.
   • Gray brick finish on the ground, first, and seventh floors to evoke the contemporary architecture of Northern Europe while maintaining an aesthetic dialogue with the neighboring building.
   • The lower part of the balconies and the bow-window elements were insulated to eliminate thermal bridges.
2. Refurbishment of the Roof Structure:
   • Removal of the existing roof package, maintaining the metal substructure.
   • Installation of new 20 cm thick rock wool insulation above the last floor slab, ensuring excellent thermal protection.
   • Installation of a new bituminous membrane and a grey sheet metal roofing covering.
3. Replacement of the Thermal Power Station and Installation of Solar Thermal:
   • Replacement of the current gas-fired thermal power station with new condensing generators (total power 165.6 kW).
   • Installation of 6 solar thermal collectors on the roof for the storage of domestic hot water.
4. Photovoltaic System:
   • Installation of a photovoltaic system with 15 panels of 400 W each, for a total power of 6.00 kWp.
   • Integration with new energy storage and management systems to maximize self-sufficiency.

Architectural Choices and Aesthetic Impact

Our design approach aimed to respect the aesthetics of the original building while embracing a modern reinterpretation. The black brick finish, chosen for the first two floors and the attic floor, integrates perfectly into the urban context, maintaining consistency with the adjacent building and providing a contemporary touch inspired by Northern European architecture.

Results and Benefits

Thanks to these interventions, the condominium achieved an improvement of at least two energy classes, significantly improving residential comfort and reducing energy consumption. Additionally, the installation of a photovoltaic system and solar thermal systems contributes to a reduction in CO2 emissions, aligning with our principles of environmental sustainability.
