I started my professional career in the trades, as a plumbing, heating and air conditioning technician. I know first-hand what it feels like to be on the construction site in the morning and to know what you have achieved in the evening. These days I manage complex real estate projects in several countries. Along the way, I came to know many facets of the real estate world.
What has always driven me? Curiosity and the conviction that good buildings only come about if you think about them holistically and understand them in practical terms. In line with this view, I have continued to grow and develop part-time while working. First I went to technical college, then I studied business administration, after that a master’s degree in energy and resource efficiency, and later on I took a continuing education course in sustainable real estate management.
These days I work as a technical asset manager at Deka Immobilien. I manage several properties in the office, hotel, retail and logistics asset classes in Poland, manage complex refurbishment projects in Germany, support tenant conversions and develop innovative solutions that get buildings ready for the future in environmental, functional and economic terms.

Christian Bierenfeld joined Deka Immobilien in 2022 in the role of Senior Sustainable Real Estate Manager and now holds the position of Technical Asset Manager for Europe South and East.
