Accumin and Spain’s Ministry for the Ecological Transition launch the first national EPC database

Fragmented and inconsistent information on building energy efficiency continues to undermine the reliability of Energy Performance Certificates (EPCs), with direct implications for real estate transactions, public policy design and investment decisions. The impact is particularly significant in Spain, where these challenges have slowed progress in upgrading the residential housing stock.

In response, Accumin, in collaboration with the Ministerio para la Transición Ecológica y el Reto Demográfico (MITERD), has developed the first national database of Energy Performance Certificates, a unified, validated and pioneering initiative at country level.

This new database delivers:

• Greater transparency for citizens, companies and public administrations
• Consistency and rigour as a foundation for more effective energy and housing policies
• Enhanced information to support the renovation and energy upgrading of Spain’s residential stock

Accumin’s contribution is grounded in its expertise in data quality and enrichment, enabling advanced modelling of energy demand, consumption and emissions. This includes tools such as the Improvement Calculator, which allows households to identify opportunities to reduce energy use and emissions, as well as estimate renovation costs.

The vision is clear: a more energy-efficient housing stock not only reduces emissions and energy poverty but also increases asset value. Multiple studies confirm the existence of a green premium, whereby each improvement in energy rating can translate into higher property values.
