As countries strive to meet ambitious climate targets and improve energy efficiency, Energy Performance Certificates (EPCs) have become essential tools in national energy reporting systems. EPCs provide standardized, reliable data on building energy performance that supports governments, policymakers, and stakeholders in tracking progress and making informed decisions.

What is an EPC?

An EPC is a certificate that rates the energy efficiency of a building on a scale from A (most efficient) to G (least efficient), based on factors such as insulation, heating, ventilation, and lighting systems. It also includes recommendations for improvements.

EPCs in National Energy Reporting

1. Standardized Data Collection

EPCs create a consistent framework for assessing and reporting energy efficiency across residential and commercial properties nationwide, enabling accurate aggregation of data.

2. Monitoring Progress Toward Targets

Governments use EPC data to monitor compliance with energy efficiency regulations and to assess progress toward carbon reduction and sustainability goals.

3. Informing Policy and Incentives

Aggregated EPC information helps design effective policies, incentives, and programs to encourage energy-saving measures and investments.

4. Enhancing Transparency and Public Awareness

Public access to EPC ratings raises awareness about energy efficiency and encourages market demand for greener buildings.

5. Supporting International Reporting Obligations

EPC data contributes to national reports submitted to international bodies such as the EU and UN, demonstrating commitment to global climate agreements.
