Digitization in building technology

“Digitization in building technology will revolutionize the way we build, operate, and experience buildings. Building information modeling (BIM) in particular generates a high potential for change, while at the same time creating opportunities to develop new business segments.”

Torsten Welfonder, Senior Expert – Digitalization in Building Technology

The topic of energy efficiency in buildings is where my passion lies. After studying mechanical engineering, I initially took up a position at Transsolar developing energy concepts for large commercial buildings. Since 2007, I’ve been working in research at Bosch. One of the focal points of my work is the simulation and model-based optimization of energy systems in buildings. On top of that, since 2017 I have been head of the working group BIM@Bosch, whose goal is to prepare Bosch for digitization in building technology.

Torsten Welfonder

Senior Expert – Digitalization in Building Technology

“Please tell us what fascinates you most about research.”

In general, the thing that appeals to me about research is the diversity of the work. It’s fascinating to think about how I can apply intelligent solutions from another area to my current problem.

“What makes research done at Bosch so special?”

Research at Bosch is so appealing to me because the energy-efficient features I develop can have a very wide global reach. What’s more, having the different operational areas means there are fantastic opportunities to utilize synergies and to transfer solutions from one area to another or to combine knowledge.

“What are the biggest scientific challenges in your field of research?”

By 2050, we will need to have doubled the entire global building stock in order to accommodate the projected growth of the population. In addition, new buildings will have to be of low cost and use next to no primary energy (net zero energy buildings).

“How do the results of your research become part of solutions "Invented for life"?”

To be able to achieve the rate of new buildings required by 2050 with minimal consumption of resources, there needs to be a revolution in the way in which we build and operate buildings. This can only happen through digitization. This is where my research at Bosch makes a significant contribution.
