*The ERI or EPA Energy Star Path – This must be checked on the Residential Energy
Compliance Form if either of these two compliance paths are chosen. Be aware that if
using the ERI compliance path or the Energy Star compliance path, a certificate or report
must be uploaded showing that the ERI is equal to or less than the ERI in the IECC (ERI
path) or the State of Texas Requirement (Energy Star)
Compliance Path and Respective Inspection Requirements – Residential Additions
The following indicate the information needed to submit through the Residential Energy
Compliance Form for a home addition:
Prescriptive Only – Section R502:
Insulation materials, R-Value, and Continuous Air Barrier as installed.
Fenestration U-Factors, Solar Heat Gain Coefficients as installed.
Mechanical HVAC ((only required with a new complete HVAC system)
Plumbing hot water system (only required with a new Hot Water system.)
Testing for air leakage is NOT required under the 2021 IECC.
Batch Testing - Thermal Envelope and Duct Testing for R-2, R-3, and R-4
Occupancies
Batch Testing - For a building having seven (7) or more dwelling units, a minimum of 15%
of the dwelling units in each building must be tested as required by Sections R402.4.1.2 -
building envelope testing, and R403.3.5 - duct testing. For building with less than seven
(7) dwelling units, one unit will be tested. If each tested dwelling unit within the batch
meets code requirements, then all dwelling units in the batch are considered to meet
code.
Batch Identification and Sampling - The builder shall identify a "batch" which is a building
where the dwelling units are completed and ready for testing. The third-party testing
contractor randomly selects at least 15% of dwelling units from a batch for testing. All units
within the batch must be ready for testing (drywall complete, interior door jams installed,
HVAC system installed, and final air sealing completed) before the testing contractor can
select the units to be tested.
Failure to Meet Batch and Sampling Code Requirement(s)
1. If any dwelling units within the identified batch fail to meet a code requirement
because of testing, the builder will be directed to fix the cause(s) of failure, and 30
% of the remaining dwelling units in the batch will be randomly selected for testing
regarding the specific cause(s) of failure.
2. If any failures occur in the additional dwelling units, all remaining dwelling units in
the batch must be individually tested for code compliance.
3. No building may be issued a Certificate of Occupancy until testing has been
performed and passed on the prescribed number of dwelling unit(s) selected for
testing as indicated above.
