The age of a residence and its energy class are two of the most decisive factors in establishing its price in the real estate market. A recent analysis by Spitogatos revealed the annual changes in average asking prices for the sale and rental of homes, indicating a clear correlation between energy class and property value in the regions of Attica and Thessaloniki. Homes with higher energy classes (A+, A, B+, B) consistently command higher prices across all sectors, as compared to those of medium (C, D, E) or low energy classes (F, G).

Specifically, in Attica, the Southern and Northern Suburbs maintain the highest average asking prices for homes across all energy classes. In the Southern Suburbs, for example, the average asking price for a home with a high energy class is reported to be 52.1% higher than that of a similar home with a medium energy class. This price differential underscores the growing importance of energy efficiency in the property market, as both investors and buyers increasingly prioritize sustainable living options.

Moreover, this trend is indicative of a broader shift in consumer preferences towards energy-efficient properties, prompting homeowners to consider upgrades and improvements to their residences. As energy prices continue to rise, the demand for properties with high energy efficiency is expected to increase further, cementing their premium market position. This dynamic not only affects pricing strategies for realtors but also has implications for urban planning and future residential developments in Attica and Thessaloniki.
