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.


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.

As a building manager, you have to juggle many responsibilities at the same time. You must comply with increasingly stringent energy and climate regulations (such as EPC NR), organise structural and cost-efficient maintenance (through condition assessments and MJOPs), and at the same time keep energy costs under control through targeted energy audits. In practice, these trajectories often run in parallel, while the associated data is scattered across different systems and reports. As a result, the overall overview is lost — costing both time and money.

Investing in comfortable workplaces pays off. VDAB proves this with the results of its most recent Comfortmeter survey, conducted by Factor4. After the first measurement in 2017, a new survey was carried out in the winter 2024-2025 to assess how employees experience their workplace comfort. The result? A noticeable improvement in both satisfaction and overall well-being at work.
