Blower Door Test — Thebarton Renovation & Extension
Project overview
A pre-renovation airtightness test on an existing home at Thebarton, ahead of a planned renovation and extension. The existing building fabric proved leaky enough that we had to run our Retrotec Model 5000 fan in its open configuration with range plate A to get an accurate reading. We tested two configurations — including the existing lean-to, and with the lean-to excluded — to set a baseline ahead of the works. As part of the renovation, HiPer Haus will also be designing, supplying and commissioning an MVHR system, supplying a Reclaim Energy CO₂ heat pump hot water system, and fitting range hood makeup air.
19.78 m³/(h·m²) @ 50 Pa
Air permeability, incl. lean-to
≈12.2 m³/(h·m²) @ 50 Pa
Air permeability, lean-to excluded
Outcome
Baseline result: 19.78 m³/(h·m²) @ 50 Pa including the lean-to; ≈12.2 m³/(h·m²) @ 50 Pa with the lean-to excluded — a clear baseline to compare against once the renovation and new MVHR system are complete.
