EU Taxonomy vs BER: Understanding the Key Differences

While both EU Taxonomy Reports and BER Certificates relate to building sustainability, they serve different purposes and audiences. Here's what you need to know about each.

BER Certificates: Energy Performance Rating

A Building Energy Rating (BER) certificate is a standardised measure of a building's energy performance. It rates buildings on a scale from A (most efficient) to G (least efficient), similar to energy labels on appliances.

BER certificates are legally required when selling, renting, or advertising a property in Ireland. They're based on the physical characteristics of the building—insulation, heating systems, windows, and so on.

EU Taxonomy Reports: Sustainability Alignment

EU Taxonomy Reports are broader in scope. They assess whether a building meets the EU's criteria for environmental sustainability, covering climate mitigation, climate adaptation, and ensuring no significant harm to other environmental objectives.

EU Taxonomy Reports are primarily used by investors and financial institutions for SFDR compliance and sustainable investment decisions.

The Connection

BER data forms part of the EU Taxonomy assessment. A building's energy performance is one factor in determining EU Taxonomy alignment for climate mitigation. However, the EU Taxonomy assessment goes beyond energy to consider adaptation measures and other environmental factors.
