HERS HERS Index Scoring 2

Question 1

A home receives a HERS Index score of 0. What does this indicate?

Accepted Answer

The home is a net-zero energy home that produces as much energy as it consumes

Answer

A HERS Index of 0 indicates a net-zero energy home where annual energy production equals annual energy consumption.

Question 2

Which software tool is most commonly used by certified HERS raters to calculate HERS Index scores?

Accepted Answer

REM/Rate or equivalent RESNET-approved software

Answer

HERS raters use RESNET-approved software such as REM/Rate, EnergyGauge, or equivalent tools to calculate HERS Index scores.

Question 3

If a home's HERS Index is 85, approximately how much more or less energy does it use compared to the HERS reference home?

Accepted Answer

15% less energy than the reference home

Answer

A HERS Index of 85 means the home uses 15% less energy than the reference home (100 − 85 = 15%).

Question 4

What is the primary purpose of the HERS reference home in the rating system?

Accepted Answer

To provide a standardized baseline for comparing energy performance

Answer

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.

Question 5

Which of the following home features would most directly LOWER a home's HERS Index score?

Accepted Answer

Installing rooftop solar photovoltaic panels

Answer

Rooftop solar PV panels generate on-site renewable energy, which reduces net energy consumption and can significantly lower the HERS Index score.
