The scaffolding is coming down and Second Fix at our Passivhaus project in Nailsea is well underway. Oak architrave and skirting boards are being fitted and the beginnings of the kitchen on this timber framed newbuild near Bristol that achieved a preliminary air test result of 0.27ach in February.
It's all go on site at our current newbuild in France Lynch, Gloucestershire at the moment!
Firstly, a visit from Darren Evans Assessments delivered an impressive air test result of 0.64ACH yesterday. This highly insulated, single-storey timber frame home has never been intended for Passivhaus certification (which requires 0.6ACH or lower) but we are very happy with this result nonetheless!
It's all systems go too with our guys installing WARMCEL insulation and preparing the roof for sedum - more photos to come.
The preliminary air test was carried out on our Nailsea Passive House project on Friday 9th February, achieving the excellent result of 0.27ACH.
The house is due for Passivhaus certification once completed but at the moment we are at first fix stage - air tight and weathertight - hence the preliminary test.
The result required for Passive compliance is 0.6 ACH @ 50 Pascals and the figure achieved was 0.27 ACH (lower is better).
This is a great result and as ever testament to the hard work and attention to detail shown by our guys on site - well done!
