What Does Energy Class A+ Mean in Practice?

More than an Indicator

In Thessaloniki’s property market, “Energy Class A+” shows up everywhere.
For many, it’s just a number.
💡 In reality, it’s the difference between a home that wastes energy and a home that works for you.

What is Energy Class A+ in real estate?

A building’s energy class expresses how efficiently it uses energy for heating, cooling, lighting, and hot water.

A+ is among the highest performance tiers and typically means a home that:

  • Uses up to 60% less energy than older housing stock,
  • Maintains a stable indoor temperature without over-reliance on heating/AC,
  • Carries a significantly smaller environmental footprint.

Everyday advantages of an A+ home

🔹 1. Lower bills

A+ homes can consume 50–60% less energy.
👉 tangible savings every month..

🔹 2. Year-round comfort

With proper insulation and modern systems, temperature stays steady in winter and summer.

🔹 3. Healthier indoor air

Right ventilation and moisture control reduce issues like mold and poor air quality.

🔹 4. Higher asset value

Energy class affects marketability. An A+ home in Thessaloniki is more attractive to future buyers and tenants.

Buyer tips for A+ homes

  • Ask for the Energy Performance Certificate (EPC/ΠΕΑ) before you buy.
