E.E: What can you tell us about market trends?

T.K: Beside the actual situation to create a healthy indoor environment against SARS-CoV-2 there’s a clear trend to implement ventilation into the smartHOME and smartBuilding technology.

E.E: What estimations do you have for 2021?

T.K: A clear estimation is not possible in these crazy days. Personally, we hope to continue our efforts successfully and create a win-win situation for both, our clients and Helios! The most important thing is that we all stay healthy. And healthy air is one of the most important parts of this. Let us therefore make the buildings fit for the future.
