The Agency for Nature and Forests (ANB) is taking an important step towards a sustainable and efficiently managed real estate heritage. With a thorough inventory and a strategic real estate plan, Factor4 is helping them on their way to climate neutrality by 2050. How do we tackle this? Find out here!
Factor4 supports the Agency for Nature and Forests (ANB) in an important project to prepare their real estate portfolio for the future.
The project started with a thorough inventory of all ANB's real estate. Factor4 carried this out in collaboration with Freestone. During this phase, we carried out numerous site visits and carefully mapped out the condition and energy efficiency of the building envelope and the technical installations. In addition, we evaluated the current use, typology, function and future-proofing potential of the buildings. This comprehensive analysis resulted in a detailed inventory of as many as 250 buildings, clearly defining the current condition of each building.
With the inventory as a solid foundation, Factor4 took the next step: developing a strategic real estate plan. This strategic exercise will help ANB to:
- Manage their patrimony efficiently and cost-effectively.
- Make long-term decisions that contribute to sustainability and value creation.
- Make their buildings more sustainable and climate-neutral by 2050.
The strategic plan not only provides ANB with a clear roadmap for sustainability, but also ensures optimal resource allocation. The careful planning of renovations and investments allows to minimize both the financial and operational impact.


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.
