Understanding the Energy Passport for Residential Buildings

Understanding the Energy Passport for Residential Buildings

The Energy Passport classifies residential buildings according to their energy performance, and is essential when selling, renting, converting, extending or building a property. In Luxembourg, it is valid for 10 years.

What is the Energy Passport?

The energy performance certificate provides detailed information on a building’s calculated energy requirements and CO2 emissions. There are three main classifications included in the EPC:

  • Energy performance class (A+ to I): based on the building’s primary energy requirement.
  • Thermal insulation class: based on the building’s heating requirements.
  • Environmental performance class: based on the building’s CO2 emissions.

The Energy Passport Certificate (EPC) is mandatory in the following cases:

  • For the construction of a residential building requiring planning permission.
  • When extending a residential building.
  • Each time the owner or tenant of an existing residential building changes, unless the building already has a valid energy performance certificate.

Exception: The EPC is not required if the sale is for demolition purposes, or in the event of a public sale by auction, seizure of property or public auction.

The Energy Classifications:

  • A+ (excellent performance): A+-rated buildings are the most energy-efficient. They consume very little energy for heating and cooling, and their CO2 emissions are minimal.
  • I (very poor performance): At the other extreme, I-rated buildings require a lot of energy to operate and have a high carbon footprint.

Why is the EPC important?

Establishing an energy performance certificate is not only compulsory, it is also a valuable tool for :

  • Buyers and tenants: They can assess a building’s energy efficiency and estimate future energy costs. EPCs have gained in importance in recent years, particularly with banks when applying for a loan.
  • Owners and investors: EPCs can influence the resale or rental value of a property. The STATEC has found that “a house in class A-B-C sells for 9.9% more on average than a house in class D-E-F. The average transaction price of a low-efficiency house is even 38.3% higher.
