Background
The project goal is to undergo testing at the final point in construction to determine if the unit
meets the 2015 IECC requirements for infiltration. Active Energies was contracted to perform a
final blower door test to determine total air infiltration. The home is permitted under the Town
of Vail and requires blower door testing per the IECC. The blower door testing must show a
tested value of 3 ACH50 or lower in order to comply with the IECC.
Site Observations
Construction of the building envelope was complete. All exterior openings were shut and locked
and interior doors were open. Cover plates on electrical and AV boxes were partially installed.
The ERV was left in the off position, but intake and exhaust were uncovered. The blower door
test was performed in the garage man door of the unit. The pressure probe place outside.
Blower Door Test
The unit was depressurized, utilizing blower door testing equipment to a pressure of-50 Pa. At
the test pressure, the CFM50 was recorded, in order to determine the ACH5o.
The blower door air leakage resulted in the following measurements: 2.9ACHso

The insulation in this corner seems to be compromised. There may be an exterior
penetration or other infiltration point allowing air into the corner wall assembly. This may
be hard to identify as the units are pre-built.
