The challenge
PROXIMUS pursues a clear sustainability strategy but faces a fundamental challenge during asset acquisitions:In the early due diligence phase, the necessary data is often incomplete. Typically, there is no detailed data available on consumption figures or technical specifications.In this initial analysis stage, the team must gain fast, data-driven insights—without relying on costly external consultants.
“From a due diligence perspective, consultants can be brought in at a later stage—but relying on them during the initial analysis phase wastes valuable resources and time.”

The solution
With Predium, PROXIMUS can quickly address the challenge of incomplete ESG data during real estate acquisitions.Using just the energy performance certificate—and without an initial on-site inspection—Predium’s software delivers comprehensive insights. Missing data is supplemented through AI and 3D modeling, creating a precise digital twin of the building that provides a reliable data foundation for informed decision-making.
“To comply with the German Climate Protection Act, we need to know: What are my building’s emissions? Where is the potential for savings? Which measures have what impact?Predium offers a simple solution that gives us exactly these insights. Working with software tools like Predium is fast, efficient, and helps us conserve valuable resources.”
