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.

Energy retrofitting: Apartment (middle floor) in Cutro, starting from class E

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.

  1. D
    1 Class D Start here −48% energy
    EP ~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.
  2. C
    2 Class C −67% energy
    EP ~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.
  3. A1
    3 Class A1 −77% energy
    EP ~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.
  4. A2
    4 Class A2 −82% energy
    EP ~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.
  5. A3
    5 Class A3 −86% energy
    EP ~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.
indicative investment → Class A3 28,000–75,500 € −86% energy
