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!
