Factor4 facilitated the Building Performance Contract (BPC) - an innovative energy performance contract - of the City of Sint-Niklaas. Luminus Solutions is the ESCO implementing the project. This innovative project has now been nominated for Facility Project of the Year, an award presented annually by Belfa, the Belgian Facility Association.
Sint-Niklaas wants to be energy neutral by 2050. One of the most important ways to achieve this ambitious goal was to conclude an innovative energy performance contract (EPC).
In preparing the energy performance contract, the city was guided by Factor4, which deployed its innovative Building Performance Contract (BPC) for this purpose. All possible data of the buildings were inventoried, down to the smallest details. Then the contract was put on the market.
Luminus Solutions offered the most attractive proposal in terms of savings and investments. The contract started on January 1, 2022 and runs for ten years.
This innovative project has now been nominated for Facility Project of the Year, an award presented annually by Belfa, the Belgian Facility Association.
A jury of experts will judge the project, but you too can cast your vote here.


Factor4 supported Laakdal in the development of the strategic real estate plan. The objective: to structurally align municipal real estate with the public services provided by the local authority, both today and towards 2050.

Many local authorities manage an extensive portfolio of buildings, but often have limited capacity to structurally monitor their energy consumption. As a result, simple optimisations are frequently overlooked, even though these so-called “no-regret measures” can deliver fast and measurable energy savings.

In 2010, Factor4 was the first Belgian consultancy firm to examine the then relatively new and promising Dutch standard NEN 2767. This standard makes it possible to assess the technical condition of building components and installations in a uniform, objective, and reproducible manner.
