Audit énergétique  ​

The renovation strategy must be based on the renovation obligation schedule of each region. As part of the European objectives for neutrality by 2050, all residential buildings will need to achieve a target energy performance (EP).

The EPB is at the heart of this renovation strategy. Therefore, we recommend conducting an EPB audit, carried out by a certified expert, to help you understand how your building should be renovated in the coming years to meet the obligations of 2033-2045-2050.

Before January 1, 2031, each housing unit must have an energy performance certificate (EPC). This document will serve as the reference for determining the mandatory renovation strategy to be implemented.

By January 1, 2033, all energy-inefficient units (F and G) within the condominium must have been renovated. If this is not complied with, fines (explained below) will be imposed.

Starting in 2045, a PEB C must be achieved, and by 2050, a PEB C+.

41% of properties in Brussels do not comply with the 2033 target, and more than 80% do not comply with the 2050 target. This obligation for the region stems from the European goals of carbon neutrality by 2050.

All apartments in the condominium with a PEB rating below E- will have to pay fines starting in 2033 (+40% of residential properties in Brussels are affected). The calculation of the fines takes several criteria into account: the square meters of the concerned unit multiplied by the theoretical consumption of the PEB certificate – 275Kwh/m²/year (with a maximum cap of 125 points) and then multiplied by a ratio of 2.5. The result gives the amount of the fine per apartment. For a class G apartment of 100m², the fine will be a maximum of €31,250..

As part of our PEB audits, we systematically calculate the fines and provide you with the means to avoid them.

If each owner remains responsible for the private parts of their property (ventilation systems, window frames, etc.), all co-owners are jointly responsible for the renovation of the common areas. This means that for all apartments with an energy performance certificate (EPC) lower than E within your building, fines (starting in 2033) will be imposed on the condominium, and the various co-owners will be jointly liable for paying them.

Conducting an energy performance audit with EasyPrimes allows you to benefit from a clear roadmap for your upcoming work. You will be able to understand how to avoid fines related to the new regulations on energy-inefficient buildings. Our approach focuses on prioritizing interventions that have the greatest impact at the lowest cost, while taking into account the specifics of your building, such as permits, access to the walls to be insulated, and other technical constraints.

Our approach stands out by taking into account the PEB rules as well as the score to be achieved after the work, allowing you to obtain the desired PEB result. Just like an energy audit, we also include an analysis of the return on investment time, evaluating the savings made compared to your current consumption, to provide you with a comprehensive view of the energy and financial benefits. Finally, we also advise you on the implementation of the work and the potential grants available for each recommendation.

First of all, some certificates are outdated and the methodologies have evolved since 2017, which could change your score. Next, the audit provides a customized renovation strategy, optimizing the costs and impact of the necessary interventions while taking into account the specifics of your building.

Unlike an architect, who can provide renovation recommendations without precisely assessing the impact on the energy performance certificate (EPC) score of the various units, our approach focuses on the energy renovation strategy based on the EPC protocol. We make projections on the target EPC score after renovation by taking into account all the necessary interventions to achieve this goal. We focus exclusively on the energy and EPC aspects of your building. We often intervene before an architect to determine the scope of the building's energy renovation, but if an architect is already appointed, we sometimes collaborate to establish the scope of the work.

Our report includes an assessment of your compliance with current standards, as well as a renovation strategy that takes into account upcoming legal deadlines (2033, 2045, 2050). We also detail the actions to be taken to remain compliant in the long term.

We assess all the elements impacting the energy performance certificate (EPC), including insulation, frames, regulation, heating, renewable energies, and domestic hot water (DHW). Based on this analysis, we provide specific recommendations to improve the EPC score of each unit and the overall energy efficiency of the building.

We analyze your current installations and, if modifications are necessary, we provide you with specific recommendations. We also assess your actual consumption and estimate the impact of the work on your future consumption, calculating the potential savings and return on investment for each proposed measure.

We assess the cost of the work based on our database of current prices. Additionally, our experience in calculating premiums for over 300 renovation files per year allows us to provide you with accurate and reliable estimates.

The audit begins with a framing session with stakeholders to define the approach and the sample apartments to visit, followed by the establishment of a schedule. We then proceed with visits to the apartments, common areas, and the boiler room, while collecting any missing evidence. We send you PEB test certificates for validation. We then develop an energy renovation strategy tailored to the condominium. Finally, we present the audit results to the stakeholders and share detailed recommendations for the renovation.

Yes, the audit includes an assessment for each visited unit, detailing the necessary work to achieve the target objectives. We provide a report on the expected outcomes for each apartment, allowing each co-owner to know the "individual return on investment" before deciding to proceed with the proposed work. Depending on the configuration of your building (condominium with more than 6 units), we use an approach based on sample apartments in order to limit the number of apartments visited. 

A certificate can be provided upon request. It is a paid option available according to your needs.

In the context of large residential buildings, we work with an approach based on model apartments, which means that not all apartments are visited (especially since some units may be comparable). Obtaining an official energy performance certificate (EPC) is optional and can be requested by the co-owners if desired.

If a property owner has undertaken renovations, they can then request a new certificate to demonstrate the improvement of their housing.

Finally, an EPC is valid for 10 years, so it may be necessary to renew it.

No, visiting all the apartments is not always necessary if some units are comparable. We conduct a survey based on sample apartments, which allows us to assess the entire building without visiting each unit. The number of visits depends on the size of the condominium and the specifics of the building. However, during the visit, we also need access to the common areas (basement, attic, parking, and boiler room). 

We now offer the same service in Brussels and Wallonia. However, in Wallonia, we must use the mandated housing audit approach. We also plan to offer this service in Flanders soon. Please feel free to contact us for a quote.

Our prices depend on the number of units and are available on our website. For small buildings, you can order directly online. ici.

For buildings with more than 6 units, our offer is systematically on quotation. We use a sample apartment-based approach, which means that the number of apartments visited may vary. On average, we visit between 20% and 30% of the apartments for large complexes, with an average cost of €400 excluding VAT per visited apartment. We also need to inspect all technical installations and common areas to determine the energy performance certificate (EPC) of the building as a whole.

Yes, our audit is eligible for the Brussels Environment grant. However, the availability of grants for 2025 has not yet been confirmed, so it is recommended to conduct the audit in 2024 to benefit from it, provided that the promises made by the members of the future government are upheld (see the question below on this subject).

Even without a grant, the audit is valuable because it allows for understanding the conditions of upcoming work and defining a pragmatic renovation strategy. Members of the future government have committed to ensuring that audits conducted in 2024 can benefit from the grant. This will need to be confirmed as announced by the outgoing government, but payments are expected to resume in January 2025. The current grant for the audit is a maximum of €3,000 (or 90% of the investment), but it may not be as advantageous in the future. Therefore, there is a benefit to ordering your audit now.
