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

    Answer: Optimize design for energy efficiency

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

  2. Which software tool is commonly used for HERS energy modeling?

    Answer: REM/Rate

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

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

    Answer: Insulation and orientation

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

  4. What is the HERS Index Score?

    Answer: A numerical energy performance rating

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

  5. How does shading impact energy modeling?

    Answer: Reduces cooling demand

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

  6. Why are air changes per hour (ACH) important in energy analysis?

    Answer: Reflects how often air is exchanged

    ACH measures how often indoor air is replaced; lower ACH rates can improve efficiency when controlled ventilation is present.
