Estimated energy class: E — Apartment (middle floor) in Cutro, 100 m²
The assessment shows your Cutro apartment is rated energy class E (APE/EPC). This result is driven by the building’s pre‑1945 construction, single‑glazed windows, the absence of wall and roof insulation, and a standard gas boiler serving a climate zone C.
With a floor area of 100 m², an EP of 132.3 kWh/m²·year and CO₂ emissions of 25.9 kg/m²·year, the dwelling’s performance reflects three occupants and a modest 0.3 kWp photovoltaic system, which contributes little to the overall energy balance.
The central estimate places the property in class E, while the best‑case scenario remains at E and the worst‑case drops to class F. These grades indicate significant room for improvement through targeted upgrades.
Most likely class E, possible range E–F.

To raise the rating, start with a heat pump installation (cost €8,000‑€18,000) to reach class D. Next, add external wall insulation (cappotto) (cost €16,000‑€40,000) to move up to class C. Installing a 3 kWp photovoltaic system (cost €20,000‑€47,500) can push the class to A1. Finally, replace the windows (cost €24,000‑€61,500 for A2, €28,000‑€75,500 for A3) to achieve the highest possible grades.
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 −48% energyEP ~69 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 ~43 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 −77% energyEP ~31 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 ~23 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 −86% energyEP ~19 kWh/m²·year
- + Replace the windows 4,000–14,000 € Double- or triple-glazed windows that stop draughts and heat loss from the windows.
