Energy certificate: mandatory document for tenants and buyers - that's how it works!

What's new in the field of commercial real estate? On August 24, 2025, an interesting offer is available to take over a company facility in the hotel industry. However, it should be noted that this is not a real estate sale, since the property is currently rented. The takeover takes place against transfer, and unusual contact by brokers are prohibited according to § 7 UWG. The provider, OM, does not act as an intermediary, but only offers a platform for real estate owners, where advertisements can be published on several real estate portals at the same time, as lunglueck.de reports.

Another important point in the industry is the energy certificate. This official document evaluates the energetic quality of a building and serves the transparency and comparability, especially for potential tenants or buyers.

This also applies to new buildings in which the ID must be created during the planning.

So if you want to be successful in the industry, you should keep an eye on these aspects for each transaction, while at the same time the latest offers, such as taking over the operating device, should not be lost.
