The 15th International BUILDAIR Symposium is a two-day professional conference focused on practical issues in building airtightness, thermography and ventilation systems. Its stated aim is to share information on current developments and approaches, and to support exchange among practitioners across national borders.23
The event is intended for measurement teams, planners, craftspeople, architects and energy consultants, with specialist colleagues from Germany, Europe and beyond invited to attend.2 Its programme is expected to address measurement experience during construction, identifying and assessing air leakage, airtightness in existing buildings, products and ventilation strategies. Other proposed subjects include infrared thermography, artificial intelligence and legal questions concerning airtightness and ventilation.4
The symposium is organised by Energie- und Umweltzentrum am Deister (e.u.[z.]) in cooperation with FLiB, VATh, theCH, AIVC, INIVE and TightVent; additional cooperation partners include GIH, DEN, IG Passivhaus and Passivhaus Institut.4 The e.u.[z.] is identified as the conference organiser on the official symposium site.3 A trade exhibition is planned alongside the conference, including opportunities for companies working in airtight building envelopes, thermography and ventilation technology to present products and services.23
The event will take place in Hannover, Germany, on 17–18 June 2027. The official symposium site lists the H4 Hotel Hannover Messe as the venue and says conference interpretation will be provided in English and German.23 The submitted information does not establish when the symposium series was founded, so no founding date is stated here.
