LEED O+M
The process evaluates the operation of an existing property based on consumption data, operational concepts, and technical condition – and provides the results digitally for ESG rating portals. As auditors and engineers, we support your property through to the issuance of the certificate.

The system at a glance
Certification body: GBCI – Green Business Certification Inc.

Classification
A streamlined, data-driven assessment process for operational real estate. It evaluates consumption data, operational concepts, and the technical condition of the property. The results are provided in digital format and can be used in ESG rating portals. Documentation is provided in English.
Unlike systems that accompany the planning phase, LEED O+M evaluates the status quo. The process describes how a property is currently operated rather than developing a strategy for how it should be operated in the future.
If you have to report anyway, this process provides the data automatically
ESG and CSRD reporting
Data transfer to rating portals
Divestment
Transparency in existing buildings

When a different system is a better fit
If no consumption data is available for your property or if consumption is significantly higher than average. The process evaluates the status quo and does not develop strategies to improve this status beforehand. In this case, we first discuss measurements, audits, and operational concepts—and address certification once the data is in place.

Frequently Asked Questions
Is LEED O+M the right certification for our property?
A property in good condition regarding cleanliness and safety, as well as an inner-city location with good public transport connections, are strong indicators, as both are rated highly in the process. It is also suitable if your property is traded internationally, managed within a portfolio, or if you are subject to ESG and CSRD reporting requirements. Conversely, a lack of data or above-average consumption levels are disadvantages, as the process evaluates the status quo.
How long is the certificate valid?
Three years. You can update it after just twelve months, for example if you are aiming for a better result.
Does the system provide ESG-relevant data for an exit?
Yes. Consumption data and KPIs are documented, and we provide a digital interface for rating platforms like GRESB at both the building and portfolio levels.
Do US standards pose any difficulties for us?
No. We only use English-language documents when communicating with the system provider or if you specify English as the contract language. Otherwise, we speak and write in German. An exception is the Technical Due Diligence as an energy audit, which must be set up according to the ASHRAE standard. We prepare this audit ourselves and are familiar with the US standard.
