The conference will be held at Vienna University of Technology, Austria.
The conference venue is the Faculty of Electrical Engineering and Information Technology, which is located at Gußhausstraße 27-29, 1040 Wien (dark green building on map).
The workshops, however, will take place in Gußhausstraße 25, 1040 Wien, which is only one building away (it is part of the dark green block of buildings, see map on right-hand side below).

The registration desk for workshop and conference participants will be located at the conference venue in Gußhausstraße 27-29, 1040 Wien (dark green building on map).

The venue is located near subway station Karlsplatz, where three subway lines stop (U1/U2/U4). Take exits Resselpark or Karlsplatz and you will be in front of the main building of the Vienna University of Technology. Go to the fountain (in front of the Karlskirche (St. Charles's Church)) and turn right into Karlsgasse. Follow this street which will bring you directly to the conference venue (dark green building on map).

To get from the airport to the U1, you can take the Airportbus to Schwedenplatz/Morzinplatz (8 euros). The bus service runs through the night; and during the day a bus leaves the airport every half hour. At Schwedenplatz/Morzinplatz you are right at the U1/U4 junction, you need to take U1, direction Reumannplatz, to get to Karlsplatz.

Alternatively, it is possible to use the S-bahn to Wien Mitte (S7, directed to Floridsdorf) and from there with U4 to Karlsplatz (4.40 euros, or 2.20 if the public transport in Vienna is already covered by another ticket). There are ticket machines at the platform, and at (some of) the stairs leading to the platform. The S-bahn runs in half-hour intervals, but not through the night.
For more information see: S-Bahn

There is also the green CAT-line from the airport, which stops at less stations than the S-bahn (11 euros, every half an hour).
For more information see: City Airport Train / CAT

Arriving by train will probably take you to either Westbahnhof or the Hauptbahnhof. From Hauptbahnhof you find immediately the subway U1 (take U1, direction Leopoldau, and get off at Karlsplatz). From Westbahnhof you can take subway U3 (direction Simmering), change to U1 at Stephansplatz (direction Reumannplatz), and finally get off at Karlsplatz.
