A home in Climate Zone 5 has a confirmed HERS Index of 62. Under 2021 IECC, this home most likely:
Answer: Complies, as the 2021 IECC path allows HERS-based compliance at that threshold
The 2021 IECC ERI compliance path sets zone-specific thresholds; Climate Zone 5 allows ERI scores up to 62 for code compliance without renewable credit.
What is the purpose of the 'projected rating' in the HERS process?
Answer: To estimate a home's energy performance before construction is complete for design feedback
A projected rating is a pre-construction or mid-construction estimate used for design guidance and preliminary compliance documentation.
Under RESNET standards, which party is ultimately responsible for the accuracy of a HERS rating?
Answer: The RESNET-accredited Rating Provider
RESNET places ultimate responsibility for rating accuracy on the accredited Rating Provider, which must oversee and quality-assure each rater's work.
A rater finds that a home's mechanical ventilation system is not operating. How should this be handled for the confirmed HERS rating?
Answer: Rate the home using as-built conditions and flag the deficiency to the Provider
Raters must document as-built conditions accurately; a non-operational required system is a deficiency that must be flagged to the Provider.
Which software tool is commonly used by HERS raters to calculate energy ratings and must be accredited by RESNET?
Answer: REM/Rate or equivalent RESNET-accredited software
HERS ratings must be calculated using RESNET-accredited rating software such as REM/Rate, EnergyGauge, or other approved tools.
When a HERS rater identifies a home built without a required vapor retarder in Climate Zone 6, the correct response is to:
Answer: Document the missing component using as-built conditions and report to the Provider
Raters must model as-built conditions and report deficiencies; they cannot grant credits for uninstalled components or withhold ratings unilaterally.
What RESNET requirement governs how a Rating Provider must handle a rater whose quality assurance reviews reveal a pattern of errors?
Answer: The Provider must initiate a corrective action plan and increase QA frequency for that rater
RESNET requires Providers to implement corrective action plans and increased oversight for raters demonstrating patterns of inaccuracy in QA reviews.
