A principal with a Kansas City architecture firm offers a step-by-step overview of a passive house design using a prefabricated panelized system in an article on the AIA web site.
“Unless thoroughly evaluated during the construction process for proper air sealing, meeting the passive house requirement for air tightness of 0.6 ACH50 is not an easy task,” the architect writes. “While verification is required through a blower door test, it is far more complicated to remediate a home for air tightness after it has been erected improperly than it is to be diligent during the design and construction process and ensure that all of the systems are continuous and properly connected and sealed.”
