Signed in as:
Maryland enforces the 2018 International Energy Conservation Code (IECC). The Maryland Code compliance requires the completion and posting of an energy efficiency certificate. The certificate lists the energy characteristics of the building materials and systems installed in your project. Blower door and duct leakage testing must be performed by an approved third party energy testing professional.
If your project involves building a new home, an addition, or major structural changes to existing exterior walls or ceilings, you may be required to demonstrate a minimum level of air tightness. Air tightness is measured through a blower door test, which is required by the code to demonstrate compliance.
New ductwork in a home must undergo a similar test (assuming some of the ductwork is located outside of the conditioned space, such as in the attic, or unconditioned crawlspace or basement).
