About me

Today we spend approx. 80% to 90% of our time indoors. For the well-being and health at work and at home, it is important to create indoor spaces that are low in pollutants. Therefore, my consulting method is according to the motto: If I know the “what” and “why”, then I know “how”.


For example, through calculations and construction benchmarks, I am familiar with the impact of grey energy and greenhouse gas emissions, especially in the construction industry. I was able to put this know-how to practical use when working on the SFOE’s “Guide to Grey Energy Modernization”. Large and comprehensive projects need creative solutions and often perserverance – it is necessary to stay on the ball, to overcome obstacles and, at the same time, to motivate stakeholders to get engaged.


As an architect, I am able to develop solutions that also meet high standards from a technical and design perspective.
