Whilst we were on holiday the second air test was performed on the house. This came back with the extremely impressive figure of 0.13 ach ( air changes per hour), which is well within the passivhaus requirements of 0.6 ach. In fact this is the lowest that Mike and his team has achieved and is even more impressive given the house is not a single rectangular unit. This would not have been possible without the attention to detail by the whole team – so a big Thank You and congratulations to the team.
