Week 76, Day 5

Week 76, Day 5:

  • Another air pressure test following the work on the window and door seals on Tuesday.
    • The build team were hoping the replacement of the sliding door seals in particular would make a big difference (despite having taped over those seals during some previous tests wth minimal impact) but I wasn’t expecting a huge improvement.
    • The test came in at 0.9 ACH @ 50 Pa whereas Passivhaus Certification demands 0.6 or lower, so still more work to do.
  • Good progress on the 50m-long swale that will take the rainwater from the house roof and attempt to disperse it before allowing any excess to drain to the field ditch through a controlled outflow
  • More minor internal snagging items completed, including re-instating the end caps on the lower flight of stair treads

Week 71, Day 3

Week 71, Day 3:

  • The day started early with another air pressure test which measured a result of 0.86 ACH @ 50 pa – compared to 0.92 at the previous test 9 weeks ago
    • So going the right way but the remedial work under the balcony didn’t have the dramatic effect the build team were hoping for
    • For reference, this equates to a hole of area 0.25 sq cm per sq m of area (and the area is 660 sq m) so that’s 165 sq cm, or an area roughly 13 cm x 13 cm
  • A bit more work on the stone cladding, though without the two extra tilers helping out
