A seasoned Partner by Your Side

With the experience gained in more than 95 successfully completed projects in Germany, China, Hungary, Bulgaria and Luxembourg, we are one of the leading providers of certification consulting services for all types of properties.

Further, we have authored a variety of manuals and guidelines around sustainability and certification.

Certification Systems

We are one of the few actors in the market with project experience in all the common certification systems in Germany. This puts us in a position to select the best system to serve as the basis for your project and meet your needs. We would be pleased to provide you with advice on the advantages and disadvantages of the different systems and explain the consequences of your selection on your planning and construction process, as well as the necessary qualities.

Our Role in Your Project

 In our projects, we consider ourselves an integral part of the planning team. Our objective is to leverage our experience to seamlessly integrate the various facets of sustainability into the project. Simultaneously, our involvement paves the way for a smooth and efficient path towards achieving certification objectives.

Our Services – your Contact

As co-developers of the systems and a represented member active in the bodies of the DGNB, we are one of the leading providers of DGNB certification services.
With our team of experienced DGNB senior auditors, we supervise all types of DGNB projects worldwide.  Our references feature many successfully certified buildings of different types.

With our experienced team, we guide both new and existing buildings through the LEED certification process. Thanks to our network, we can also offer you many essential ancillary services, such as energy modelling.

With licenced and experienced BREEAM-DE auditors and our many years of experience in real estate and facility management, we supervise all types of projects in portfolio certification in accordance with BREEAM-DE for you.  Here as well, we can look back at many successfully completed projects.

As a co-developer of the Assessment System for Sustainable Building (BNB) as part of the research activity at the Karlsruhe Institute of Technology, we supervise public sector projects in BNB certification. We can use the Federal Constitutional Court in Karlsruhe, one of the most important buildings in the country, as our reference here.

We pool our many years of experience in the areas of sustainability and facility management in the GEFMA 160 certification. As a participant in the system development and pilot phase, we can also provide references here. Our approved GEFMA 160 auditor would be happy to provide you with advice.

As experienced sustainability auditors, we supervise projects in accordance with the NaWoh – quality seal for sustainable housing construction – certification system. We can also fall back on experience from reference projects here.

The integration of sustainability requirements into the competitive task is now standard in many competition announcements. We would be pleased to provide advice to you on which project-related topics can be meaningfully integrated into the text of the competition announcement and act as a technical consultant or jury member for “sustainability” in the competition process.

Be it a variant comparison or design optimisation, we can map the entire life cycle of a project or its components using the life cycle analysis as an instrument. As a result, we can support you with the ecological optimisation of your portfolio in detail, based on quantitative data. We would be pleased to create a life cycle analysis as a specialist service for you as part of your certification audit.

Indoor air quality is a minimum DGNB requirement. Good air quality is ensured by evaluating the ambient air concentrations of volatile organic compounds (TVOC concentration or “total volatile organic compounds”) and the formaldehyde content.

Our experienced “building biology metrologists” professionally illustrate and evaluate the presence of harmful substances in indoor room air using measurement technology and create a list of recommended measures, if any. Irrespective of whether TVOCs and formaldehyde must be measured for DGNB certification as part of SOC 1.2 or monitoring of harmful substances is required for other reasons.

Be it a variant comparison or design optimisation, new building or modernisation, we can transparently prepare or review project-related decisions with the life cycle cost calculation as an instrument.

With our team of experienced auditors, we will train you in all the common certification systems. From a general overview to an in-depth presentation on individual topics, we can conduct customised in-house training sessions. Further, we create customised manuals about the integration of sustainability requirements into your business processes upon request.
