A home receives a HERS Index score of 0. What does this indicate?
Answer: The home is a net-zero energy home that produces as much energy as it consumes
A HERS Index of 0 indicates a net-zero energy home where annual energy production equals annual energy consumption.
Which software tool is most commonly used by certified HERS raters to calculate HERS Index scores?
Answer: REM/Rate or equivalent RESNET-approved software
HERS raters use RESNET-approved software such as REM/Rate, EnergyGauge, or equivalent tools to calculate HERS Index scores.
If a home's HERS Index is 85, approximately how much more or less energy does it use compared to the HERS reference home?
Answer: 15% less energy than the reference home
A HERS Index of 85 means the home uses 15% less energy than the reference home (100 − 85 = 15%).
What is the primary purpose of the HERS reference home in the rating system?
Answer: To provide a standardized baseline for comparing energy performance
The HERS reference home is a standardized baseline built to the 2006 IECC with RESNET modifications, used to compare the rated home's energy performance.
Which of the following home features would most directly LOWER a home's HERS Index score?
Answer: Installing rooftop solar photovoltaic panels
Rooftop solar PV panels generate on-site renewable energy, which reduces net energy consumption and can significantly lower the HERS Index score.
Under RESNET standards, a Confirmed HERS Rating requires the rater to perform which of the following?
Answer: On-site inspections and testing including blower door and duct leakage tests
A Confirmed HERS Rating requires the rater to conduct on-site inspections and performance tests such as blower door and duct leakage testing to verify actual construction.
A home with a HERS Index of 130 is best described as:
Answer: 30% less energy efficient than the reference home
A HERS Index above 100 means the home uses more energy than the reference home; a score of 130 means it uses 30% more energy.
