Practice what you preach. Sustainability is in Factor4's DNA. Not only do we help others reduce their energy consumption and CO₂ emissions, we do it ourselves. Factor4 is a CO₂-neutral organization: we limit our own emissions as much as possible and offset the remaining emissions through a sustainable climate project.
How do we minimize our CO₂ emissions?
- We try to keep car use to a minimum. We do most of our travelling by public transport or bicycle. We make maximum use of the combination of train + BlueBike/folding bike, electric (shared) cars or carpooling.
- We consciously choose an office located just 5-minute walk from Antwerp Central Station (Mobiscore 9.9/10).
- We use a shared office where resources are shared with other entrepreneurs: common kitchen, meeting rooms, printers, and scanners. This helps limit our impact in terms of material and space usage.
- We embrace the principle of the paperless office and have built an IT infrastructure that allows full electronic management of projects.
Using Regreener's Footprint Navigator, we calculated our carbon emissions and more than offset them by participating in a sustainable climate project. We support tree planting in Zambia to contribute to a healthier climate. More information about this project: https://regreener.earth/nl/projecten/bomen-groeien-in-zambia

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.
