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-Lab 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-Lab, 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.

At the BTA-Expo easy orientation for the visitors is the main focus. The exhibition is divided into five Topic Districts that are differently coloured and consists of 132 standardised Expo Corners. Each district is assigned a colour in which the expo corners of the exhibitors are marked. 

The Topic Districts rotate clockwise by one position for each edition of the BTA.
