The draft Government Order amending the WGO of 15 May 2014 implementing the Decree of 28 November 2013 on BEP

Published on 05/11/21 by Isabel Zaghet
The purpose of the proposed amendments is to specify the requirements applicable to technical systems in buildings, as well as the obligations related to electromobility.

This draft Order amending the Walloon Government Order of 15 May 2014 (AGW PEB) implementing the Decree of 28 November 2013 on the energy performance of buildings, as well as its technical annexes, follows the amendments made to the BEP (PEB) decree of 28 November 2013, with a view to transposing the third PEB Directive 2018/844 of 30 May 2018.

The amending decree adopted by the Walloon Parliament on 16 December 2020 has in fact integrated new European obligations into the BEP decree and empowered the Government to specify the methods for their implementation.

Further adjustments will have to be made in a forthcoming Order concerning the implementation of the building passport and the obligation to use energy from renewable sources when applying the BEP requirements. These two issues are still under consideration.

The proposed draft Order also aims to introduce or adapt the arrangements for granting delegations of authority in order to allow, in particular, the efficient and rapid management of applications for approvals.

1. System requirements

The WGO on BEP is supplemented by an obligation (Art. 19/3, §§1 and 2) specifically aimed at large heating or combined heating and ventilation systems, as well as air-conditioning or combined air-conditioning and ventilation systems with an effective rated output of more than 290 kW, which are installed in non-residential buildings (or predominantly non-residential buildings if they are mixed). These systems must be fitted with building automation and control systems (BACS) by 31 December 2025 at the latest.

The aim is to optimise the operation of the heating and cooling systems concerned to achieve substantial energy savings and improve the management of the indoor environment of the buildings.

Some large heating and air conditioning systems already have these functionalities. The aim is therefore to upgrade existing installations of this type in Wallonia and to systematise the use of this type of control for new heating and air conditioning systems. The technical description of the requirements applicable to automation and control systems is set out in Annex C4.

The same applies (Art. 19/3, §§ 3 and 4) to the “ordinary” control requirements for heating and air-conditioning systems as well as to the insulation of the distribution circuits (heating, domestic hot water loop, chilled water and ventilation). These requirements represent current good practices. The upgrade must be carried out by 31 December 2025, for new and existing buildings, both residential and non-residential.

2. Electromobility requirements

The draft WGO supplements the amended decree by determining the exceptions permitted by the said decree (Art. 9/1 implementing Art. 13/3, § 2 of the amended decree) and by specifying the requirements applicable by 31 December 2024 to non-residential buildings with more than twenty parking spaces (Art. 19/4 implementing Art. 13/1, § 2). Such buildings will have to be equipped with the connection infrastructure for one in five parking spaces and a charging point.

With regard to exceptions, Article 9/1 includes the following assumptions:

  • the necessary connection infrastructure is based on isolated microgrids 
  • the buildings are owned and occupied by small and medium-sized enterprises 
  • where the cost of the charging and connection systems accounts for more than 7% of the total cost of the major renovations to the building

3. Delegations of authority

The approval of professionals (BEP managers, authors of technical, environmental and economic feasibility studies, BEP certifiers) involved in the BEP procedures for construction and renovation, as well as in the BEP certification of buildings, is already subject to a delegation system governed by the WGO of 23 May 2019 relating to the delegation of authority to the Walloon Public Service. Thus, the decisions to grant such approvals are entrusted to the Inspector General of the Department of Energy and Sustainable Building.

This system makes it possible to simplify the administrative process and to reduce the time between the validation of an application and the decision to grant approval.

On the basis of the preliminary analysis carried out by the administration relating to the number of buildings targeted by the new requirements, it can be considered that:

  • 5,000,000 systems (all building technical systems combined) are currently present in Wallonia. All of them will be impacted by the system requirements (new and current) in the coming years. For all works covered by the requirements, the professional working on the system will have to take into account the regulatory requirements regarding the performance of the system, as well as document the work performed and the related requirements 
  • at least 4,000 certified heating engineers (or those able to verify the requirements) in addition to the current 3,000 certified ones would be needed 
  • at least 130 energy and air-conditioning experts will also be needed to monitor compliance with the requirements (0 currently approved) 
  • for the other systems envisaged, considering the particularly high number of systems and interventions concerned, several hundred workers would be need, with a significant share of the jobs created for ventilation systems 
  • for the electromobility requirements: there are currently approximately 322,500 buildings concerned in Wallonia. Considering approximately the following averages:
    •  ½ day for pre-wiring the entire car park of apartment buildings or for pre-wiring 20% of the spaces in small non-residential car parks with a charging point;
    • 1 day for pre-wiring 20% of the spaces in large car parks with a charging point
    • It can be estimated that 261,250 working days will be created through this single measure.
