[*]I commissioned the test myself (300€) and was present.
[*]Right time for the test: plastered walls and installed vapor barrier
[*]Result 0.91
[*]Leak localization was also carried out, 2 windows were readjusted.
Was the front door used for the test at your place or another opening? If you share results, would you add whether you have a ventilation system or not? (And preferably results with units or so ...)
Unit is always the air change rate. However, this is usually not mentioned, only the value itself. The ventilation system is also not yet installed or running during the measurement. Does it still play a role? It was done at the front door for us: value of 0.93.
For the test, the entrance door was used. The ventilation system already plays a role (we have one) because the value depends on it how high it can be. A house without controlled residential ventilation Value <3.0 A house with controlled residential ventilation Value <1.5 Passive house Value <0.6
