Schoenergie: Safer, Faster, and No More Manual Measurements

At Schoenergie, roof measurements are part of the daily work of project managers—whether for residential buildings or large commercial installations. For Tobias Hausener, Head of Division, it became clear early on: with a growing number of projects, the existing process was no longer efficient enough.

Challenge

Previously, all measurements at Schoenergie were done manually.

Project managers had to go onto the roof themselves, take measurements, and create a sketch. This sketch was then transferred into CAD and redrawn to plan the PV system.

As Tobias Hausener explains, this process worked—but came with clear drawbacks.

One major issue was safety, since measurements had to be taken directly on the roof.
Another was incomplete data—missing dimensions often had to be checked later.

The biggest time sink, however, was post-processing:
Creating sketches and manually redrawing everything in CAD slowed down the entire workflow.

Solution

Today, Schoenergie uses drone-based digital measurements—and the process has changed completely.

Project managers still visit the site, but instead of measuring manually, they capture the building with a drone. The data is processed and delivered as a ready-to-use 3D model.

For Tobias Hausener, the key advantage is clear:
The process is simpler, faster, and more reliable.

All measurements are complete and available from the start—no need for follow-up checks.

Instead of creating sketches and redrawing them in CAD, the team can now start directly with PV system planning based on the model.

Overall, Schoenergie saves around 70% of time across the entire process—both in data capture and CAD work.

Today, digital measurement is fully integrated into the company.
With around 70 drone pilots, Schoenergie uses it daily for both residential and commercial projects.
