Energy efficiency now tops in Belgian real estate

The real estate market is constantly evolving, and recent trends in Belgium highlight a significant shift in buyer preferences. According to a study by ING Belgium, energy performance has emerged as a crucial factor for homebuyers, overshadowing traditional criteria such as garden size and facade count. This shift signifies a deeper understanding of long-term value and sustainability in property investment.

PEB: The New Deciding Factor

The PEB (Performance Énergétique du Bâtiment) score, which measures the energy efficiency of a building, has become increasingly influential in the Belgian real estate market. This change reflects a growing awareness of energy costs and environmental impact. As the world becomes more conscious of climate change and energy use, properties with better energy performance are not only more cost-effective but also more attractive to environmentally conscious buyers.

Shift in Priorities and Renovation Trends

The surge in energy prices in 2022 and the introduction of mandatory renovation laws in Flanders in 2023 have played a significant role in this shift. Buyers are now more inclined to consider properties that may require renovation if it means improving the PEB score. This willingness to invest in energy efficiency reflects a broader change in mindset, where long-term savings and sustainability are becoming key drivers in real estate decisions.

Generational Differences in Energy Efficiency Perception

A generational disparity is evident in attitudes towards energy efficiency. While only 37% of the 18-24 age group consider energy efficiency crucial, this figure jumps to 72% among those aged 55-64. Philippe Ledent, an economist at ING, warns of the risk that younger buyers might overpay for energy-inefficient homes due to their relative inexperience in the real estate market.

Changing Attitudes Towards Renovation

The perception of renovation has evolved significantly in 2023. A bad PEB label is no longer seen as a dealbreaker, as more households are open to purchasing a home that requires renovation, provided it fits within their budget. This trend suggests that buyers are weighing the long-term benefits of energy-efficient homes against the upfront costs of renovation.

Understanding PEB A Standards

Despite these shifts, only 28% of Belgians are aware that every house must reach a PEB A score by 2050 to align with the European Union’s standards for climate neutrality. This lack of awareness highlights the need for continued education and information dissemination regarding energy performance and its implications for property values and environmental impact.

Implications for Sellers and the Market

For sellers, this trend emphasizes the importance of investing in energy-efficient upgrades to enhance property appeal and value. As buyers become more discerning about energy performance, properties with better PEB scores are likely to command higher prices and attract more interest.

Future Outlook

Looking ahead, the emphasis on energy efficiency is expected to grow, driven by evolving consumer preferences, rising energy costs, and regulatory changes. This shift presents both challenges and opportunities for the real estate market in Belgium. Homeowners and investors need to adapt to these changes, considering energy performance as a critical aspect of property value and marketability.

For prospective buyers, understanding the long-term benefits of energy-efficient properties, both in terms of cost savings and environmental impact, will be key in making informed real estate decisions.


The rise of energy efficiency as a primary concern in the Belgian real estate market marks a significant evolution in buyer priorities. This trend underscores the growing importance of sustainability and cost-effectiveness in real estate decisions. As the market continues to evolve, staying informed about these changes will be crucial for buyers, sellers, and investors alike.
