High-quality building data is becoming increasingly important when granting real estate loans. Christian Ziemer (Goldbeck Facility Services) drew attention to this at the gefma annual event, which took place on November 13 and 14, 2025, in Düsseldorf.

Especially in times of stricter regulatory requirements and increasing sustainability standards, property owners benefit when they have can quickly provide reliable and verifiable data .

"Even an interest rate advantage of 0.1–0.3% based on reliable data leads to considerable savings for large investments," explains Dr. Andreas Seebach, co-founder and managing director of white energy.

white energy supports owners and operators in meeting precisely these requirements:
Our energy management system weEMS records and digitizes live data from all meters, provides verifiable consumption and emission data, exports it securely, and optimizes energy flows in the building at the same time.

This results in two direct advantages:

• better credit terms through transparent and reliable data
• lower operating costs thanks to optimized energy performance
