Energy-efficient new builds: what does the E-level mean?

Anyone looking at a new-build house today will soon come across the term E-level. But what does it actually mean? Is it simply a technical figure, or is it something you genuinely notice in everyday life?

From E30 to E20: nearly zero-energy new builds 

The E-level indicates how energy-efficiently a home has been designed and built. This measure is used in Flanders for new builds and major renovations to assess a building’s energy performance. At Potrell, all our new-build houses meet at least the statutory E30 standard. In some developments, we go a step further and achieve E20. The lower the E-level, the more energy-efficient the house.

E30 is the current standard and provides a strong foundation: an energy-efficient home with low energy consumption thanks to good insulation and smart, sustainable technologies. E20 goes one step further, reducing the amount of energy your home requires and resulting in even greater living comfort.

For example, Potrell is developing new-build projects in Buggenhout and Roeselare with an E-level of 20. These energy-efficient homes use a well-considered combination of systems, such as underfloor heating on both floors powered by an energy-efficient heat pump. This is complemented by solar panels and a type D ventilation system. This system continuously supplies fresh air and extracts polluted air, while recovering heat from the extracted air so that less energy is lost.

“At Potrell, we exclusively build nearly zero-energy homes and, if required, we can reduce the E-level even further through energy-efficiency measures,” says sales adviser Xavier. “Some buyers specifically ask for this. Investing in energy-efficient measures is an investment in future-proof living. Our technical partners work closely with us to provide tailored solutions.”

New builds offering living comfort and control over your energy bills

A strong E-level makes a difference every day. Choosing a new build means choosing living comfort and greater control over your energy bills. Energy-efficiency requirements for buildings in Flanders are becoming increasingly stringent. Rising energy prices and stricter climate targets also play an important role. An energy-efficient home is better equipped to cope with these developments and protects you against unexpected costs in the future. You consume less energy, are less dependent on external factors and retain greater control over your energy bills.

That is precisely why Potrell looks beyond the figure itself. We help you understand what lies behind the E-level, so that you are not only buying an energy-efficient home, but also making a well-considered, future-focused choice.

E-level vs EPC: what is the difference?

The E-level is often confused with the EPC. The E-level indicates how energy-efficiently a home has been designed and built, while the EPC indicates how much energy your home consumes in practice and is expressed in kWh/(m² year).

Potrell builds energy-efficient new-build houses throughout Flanders

Potrell develops energy-efficient new-build houses throughout Flanders. From Ghent and Bruges to the coastal region, and from Willebroek to Oudenaarde: we develop projects in carefully selected locations where living comfort, accessibility and future-focused construction are key. This means you will not only find a home with a strong E-level at Potrell, but also a location that works for the long term.
