606 Procedures for Inspections and Testing

The Testing and inspection of Dwelling Units for Minimum Rated Features shall be conducted in compliance with the procedures for conducting home energy Ratings contained in the RESNET MINHERS Standards.

606.1 Sample Set
A group of Dwelling Units at the same stage of construction (e.g., pre-drywall, final) within a 90-day period that the Sampling rate is applied to.

For each stage of construction, each Sample Set shall be composed of Dwelling Units eligible for the applicable Sampling Verifications within a 90-calendar day period. For example: a Sample Set that is defined for a pre-drywall inspection must include Dwelling Units that are eligible for that pre-drywall inspection within a given 90-day period. If fewer than five (5) Dwelling Units are available for that phase of inspection, the Sample Set must be limited to the number of Dwelling Units that are available within that 90-day period. Sample Sets need not be the same across different Sampled Features. For example, one Sample Set may exist for a pre-drywall inspection and, at the Rater’s discretion, a whole new Sample Set may be defined for the final inspection phase based on the Dwelling Units available for that phase within a new, 90-day period applied to that phase of tests and inspections.

Each Dwelling Unit subject to Sampling is required to be part of an identified Set of Sampling Verifications for each test or inspection that is Sampled.

606.2 Qualification Set
Sampling shall be conducted in accordance with the Sampling Plan.
To qualify for Sampling a builder must complete a Qualification Set.

606.2.1
A builder or developer shall complete and have verified the installation of a minimum of five (5) of each Sampled Feature prior to conducting a Qualification Set for each Sampled Feature.

606.2.2
Any feature being Sampled must qualify for Sampling by being successfully verified to meet the Threshold Specification for five (5) consecutive Sampled Features. A Qualification Set shall be made up of more than five (5) Sampled Features if a Failure occurs while qualifying the Feature.

606.2.3
Any feature that fails to meet the Threshold Specification shall be corrected and re-inspected and/or retested until it meets the Threshold Specification.

606.2.4
Sampling shall begin only after the Threshold Specifications have been verified in five (5) consecutive Dwelling Units without any incidence of Failure.

606.2.5
Each Sampled Feature shall qualify for Sampling independently of the other Sampled Features. The Qualification Set, and any Dwelling Units tested prior to the Qualification Set, are not part of a Sampling Set and shall not count toward the minimum quantity of Sampling Verifications required.
