The SB10 Conference Western Europe chose a challenging theme: towards 0-impact buildings and built environments. Looking back at the event which took place from the 11th up to the 13th of October in Maastricht, Heusden-Zolder, Liege and Aachen, we can conclude that this has been taken up very well by the 190 participants. The limits and ambitions were pushed, both by keynote speakers and paper authors. Most papers included the 0- ambition in their paper, and the authors explored the consequences of such ambition. Sometimes leading to lively discussions during and after presentations. The organization of the conference by Zuyd university, Cedubo, Haute Ecole de la Province de Liege and Fachhochschule Aachen was an inspiration to organize the conference itself in the four different cities in the Euregion.
