The first pressurisation test in Bulgaria for proving the airtightness Blower door EN 13829 was performed on the passive house project Water house on 26.10.2010 in Blagoevgrad. The upper limit for a passive house as a test result is 0.6 [h-1]. 0.1 [h-1] was achieved – a great result for a pioneer passive house project, thanks to the efforts of the project leader Studio APXE and all the construction companies who worked hard to complete the external envelop in complete airtightness.
You can overview the certificate soon on www.apxe.eu.
