Understanding the EPB regulations for energy-efficient buildings in Belgium

When it comes to construction or renovation in Belgium, there’s a significant emphasis on energy performance. The Performance Énergétique des Bâtiments (EPB) or Energy Performance of Buildings is a set of regulations that ensure buildings are not only energy-efficient but also comfortable and healthy for its inhabitants.

What is the EPB Regulation?

Across all three regions of Belgium, the EPB regulation aims to ensure that buildings are constructed or renovated to be more energy-efficient, healthier, and more comfortable for residents. The primary targets of this regulation are new constructions and renovations, with specific requirements and procedures tailored to these projects.

The ultimate goal of the EPB regulation is to reduce energy consumption while ensuring the indoor comfort of the building. To achieve this, the EPB regulation relies on specific procedures and a dedicated calculation method.

Who is affected by the EPB regulation?

The EPB regulation primarily affects individuals undertaking construction or renovation projects that require an urban planning permit. Specifically, if the work impacts the building’s envelope and influences its energy performance, the EPB regulations come into play.

The EPB Procedure

For significant construction or renovation projects, an accredited EPB officer must be appointed to prepare various documents:

Initial Declaration: Known as the "EPB proposal" in Brussels, this is essentially a project detailing the desired energy performance. This document must accompany the permit application.
EPB Notification: This is required at the start of the project, but only in the Brussels region.
Final Declaration: This document outlines all the measures implemented to meet the EPB requirements. It must be submitted to the relevant administration upon project completion.
EPB Certificate: This is an energy identity card for the building, indicating its overall performance. This information must be included in any document related to the sale or rental of the property.

EPB Calculation Method

While the calculation method varies across regions, the general principle remains consistent. The calculation aims to determine the building’s energy consumption for heating, hot water, auxiliary systems, and potential cooling, based on a "standard" usage. This calculation is performed using the technical characteristics of the building and its equipment, facilitated by specialized software.


The EPB regulations in Belgium play a crucial role in steering the country towards a more sustainable and energy-efficient future. For homeowners, builders, and renovators, understanding these regulations is essential to ensure compliance, reduce energy costs, and contribute to a greener environment. As the world moves towards more sustainable practices, Belgium’s EPB regulations set a commendable benchmark for energy efficiency in construction and renovation.
