#1359 EAA Air Infiltration

[Alea German]

Make sure that the Standard Design air infiltration is modeled according to Table 32 of the ACM. In a test with altered infiltration of 10ACH50 and existing verified infiltration of 10ACH50, the Proposed Design izALo values are twice that for the Standard Design. It's difficult to directly report what the infiltration values are in the model; however, it’s supposed that the Standard Design is modeled as 5 ACH50 in this case when instead it should reflect the existing condition tested value of 10 ACH50. See attached file.

Existing verified ACH50 only applies when Altered ACH50 < baseline.

mod installs verified-existing ACH50 in EAA standard design models regardless of whether the Altered ACH50 exceeds normal std design
