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!
Richard Hatfield and Malcolm McMahon were interviewed by Richard Brown of The Property Voice recently for his regular podcast. He described Greenheart as being 'on the ground pioneering sustainable building in the real world' which we can't argue with!

Lots going on at our Passivhaus build in Nailsea currently - underfloor heating going in, MVHR installed in the loft, with boards to hold in extra insulation. This home will be seriously snug and warm for its owners come next winter!
