What is the EPB Center?

The EPB Center works for the benefit of all stakeholders who are concerned with the implementation of the Energy Performance of Buildings Directive (EPBD) by acting as a dedicated information service centre for the set of Energy Performance of Buildings (EPB) standards developed under the European Commission’s (EC) Mandate M/480 to the European Committee for Standardization (CEN).

Whichever way you want to get involved - whether by following developments, accessing our services or providing feedback - the EPB Center is there for you!

What is the set of EPB standards?

The set of EPB standards is a series of standards aimed at international harmonization of the methodology for the assessment of the overall energy performance of buildings.

How do I get an overview of EPB standards?


The assessment of the overall energy performance of a building requires a holistic or systemic approach. This implies that all types of building-related energy uses (heating, lighting, cooling, air conditioning, ventilation) and outdoor climatic and local conditions, as well as indoor climate requirements are considered.
This makes that in total the set of EPB standards comprises about 50 standards.

The core set

However, the core of the set of EPB standards consists of the following five standards:

Info on all EPB standards and accompanying technical reports

Many of the EPB standards are a direct part of the methodology to assess the overall energy performance of a building by calculation. Other EPB standards cover e.g. guidance on inspection, economic evaluation procedures, system (design/sizing) requirements, measured energy performance and reference calculation procedures.

The main EPB calculation standards are presented in the following illustration. This illustration is explained in the short (6 min.) video “Mapping the set of EPB standards”.

EPB Standards Explained

EPB Center experts noticed a strong need of short introductions to specific subjects. As a result, a series of short videos has been produced to explain in a few minutes specific subjects.
More short videos may be added at later date. Suggestions are welcome!

EPB standards webinar series

A series of webinars is jointly organized throughout 2020 by BUILD UP in cooperation with EPB Center’s experts under the scope of the Service Contract with EU DG ENER. Please see below the so far webinars that have taken place or are already planned. More to come soon!



Updated tools on individual EPB standards (spreadsheets)

The spreadsheets related to the EPB standards are provided to demonstrate specific elements and features of the calculation procedures in the relevant standard(s). Consequently, they do not replace the EPB standards, but they shall be used along with the EPB standards.
