HERS Rater Energy Modeling & Analysis

Question 1

What is the purpose of energy modeling in home performance analysis?

Accepted Answer

Optimize design for energy efficiency

Answer

Energy modeling simulates a building's energy use to identify efficiency improvements and predict performance.

Question 2

Which software tool is commonly used for HERS energy modeling?

Accepted Answer

REM/Rate

Answer

REM/Rate is a widely accepted tool for HERS raters to model energy usage and generate compliance reports.

Question 3

What factor most affects heating and cooling load in a home?

Accepted Answer

Insulation and orientation

Answer

Building orientation and insulation values greatly affect heating and cooling demands.

Question 4

What is the HERS Index Score?

Accepted Answer

A numerical energy performance rating

Answer

The HERS Index Score measures a home's energy efficiency; lower scores indicate better performance.

Question 5

How does shading impact energy modeling?

Accepted Answer

Reduces cooling demand

Answer

Shading reduces solar heat gain, which can lower cooling loads in summer months.
