Advantage through new knowledge

BTA – Building Technology Austria 2020 postponed

NEW DATE: September 22nd and 23rd, 2021, Messe Wien

After the premiere of BTA - Building Technology Austria in September 2019, the second edition was scheduled
for September 30th to October 1st, 2020 at Messe Wien. Unfortunately, this appointment for the innovative B2B industry format
for all areas of building technology will not take place.

The reason for this is the continuing spread of the corona virus COVID-19, which has far-reaching effects on the European and worldwide event industry. Trade fairs have to be canceled entirely or at least postponed. Even the Light + Building in Frankfurt was forced to move and will now take place exactly in the period in which the BTA 2020 was scheduled. In order to avoid this deadline collision with the leading trade fair, we decided to reschedule the second edition of the BTA, to September 22nd and 23rd, 2021.


We will inform you in good time about the planning and content of the BTA 2021 on this website. Of course, we are always available for questions and suggestions.


We wish you all the best in these challenging times!

The BTA is a network event, expert forum and expo all in one, bringing together building services professionals from the planning, construction and maintenance sectors. It is an initiator of interdisciplinary knowledge transfer and dialogue and offers an outlook on the future of technical building equipment.
The BTA-Expo presents selected solutions and innovations of the industry for a hands-on live experience.
Following the motto “right in the middle, not merely on the sidelines”, the expert forum part of the BTA-Industry Symposium creates space for ideas, knowledge exchange and professional discourse. The comprehensive programme of lectures and panels on current topics in building technology provides the outline. The overall design of the BTA is focused on generating new contacts and networks. Be it in the moderated BTA-Industry Symposium, at the after-work event with culinary accompaniment or digitally supported by the BTA app. The BTA runs for two days and takes place annually in September in Hall D of Messe Wien.

Information on visitor ticket prices will follow in September 2018.
