Estimated energy class: E — Apartment (middle floor) in Cutro, 100 m²
The APE assessment for your 100 m² apartment in Cutro places it in energy class E. This rating reflects the building’s pre‑1945 construction, the absence of wall and roof insulation, single‑glazed windows, and a standard gas boiler as the heating system.
With an energy performance index of 133.5 kWh/m²·year and CO₂ emissions of 26.2 kg CO₂/m²·year, the dwelling falls in climate zone C (1167 degree‑days), which influences heating demand.
The apartment houses three occupants and currently has no photovoltaic installation. These factors, together with the building envelope and heating carrier, determine the overall energy performance.
Most likely class E, possible range E–F.

To move from class E to a higher rating you can follow the roadmap: installing a heat pump can lift the class to D (cost €8 000–€18 000); adding external wall insulation (cappotto) can bring it to C (cost €16 000–€40 000); a 3 kWp photovoltaic system can raise it to A1 (cost €20 000–€47 500); and replacing the windows can further improve the class to A2, A3 (cost €24 000–€75 500). Each intervention reduces the energy demand and CO₂ emissions, helping you achieve a better energy class.
How to climb a class
Not sure where to start? Here is how to raise your home's energy class, step by step. Each step builds on the previous one: reaching a class also requires the works from the earlier steps.
-
D1 Class D Start here −47% energyEP ~70 kWh/m²·year
- Install a heat pump 8,000–18,000 € Replaces the boiler with an efficient electric system: it heats, cools and uses less energy.
-
C2 Class C −67% energyEP ~44 kWh/m²·year
- + Insulate the walls (external insulation) 8,000–22,000 € External wall insulation covers the outer walls and cuts heat loss: warmer in winter, cooler in summer.
-
A13 Class A1 −76% energyEP ~32 kWh/m²·year
- + Photovoltaic system (3 kWp) 4,000–7,500 € Panels that generate electricity from the sun: they cut your grid use and your bill.
-
A24 Class A2 −82% energyEP ~25 kWh/m²·year
- + Replace the windows 4,000–14,000 € Double- or triple-glazed windows that stop draughts and heat loss from the windows.
-
A35 Class A3 −85% energyEP ~20 kWh/m²·year
- + Replace the windows 4,000–14,000 € Double- or triple-glazed windows that stop draughts and heat loss from the windows.
