Our clients include a wide range of professionals and companies, including homeowners, property managers, real estate agents, developers, project developers, architects, energy consultants, and craftsmen of all trades.

Our services range from tailor-made creation of a renovation roadmap to detailed accounting of comprehensive energy concepts for residential and non-residential buildings, both for renovation projects and new construction projects. Additionally, we offer holistic consulting and planning services covering all aspects of a construction project. Our goal is to support builders and companies involved in projects as effectively as possible.

Energy efficiency and sustainability

Within construction projects, we have the capability to integrate architectural data into our accounting software or even capture the building itself in 3D. This allows us to perform extremely precise accounting of buildings, whether they are existing buildings or new construction projects. Consequently, we are able to conduct highly detailed building physics, energy, and systems engineering calculations.

These comprehensive calculations form the basis for our ability to achieve the best possible outcome for you, both in terms of the building’s energy efficiency and the maximum available funding.

How much does an energy consultation cost?

The costs for an energy consultation can vary depending on the scope and type of consultation. There are different types of energy consultations, such as on-site consultation, construction supervision, or energy renovation consultation. Prices can also vary from energy consultant to energy consultant.

For an on-site consultation, where an energy consultant analyzes your building and provides you with individual recommendations for improving energy efficiency, the costs in Germany can range between 200 and 800 euros. The exact costs depend on factors such as the size of the building, location, and the scope of the consultation. For construction supervision, where the energy consultant accompanies the new construction or renovation and ensures that energy-efficient standards are met, the costs may be higher. Here, prices can range from several thousand euros depending on the scope of the project and the duration of the supervision.

It is important to note that there are state funding programs that can cover part of the costs for an energy consultation. Therefore, it is worthwhile to inform yourself about possible funding opportunities.
