Home Energy Rating System (HERS) Rater Practice Exam

Achieving a qualification as a Home Energy Rating System (HERS) Rater signifies a key step towards contributing to energy-efficient home practices and sustainability. The HERS exam turns theory into action by ensuring candidates possess the necessary expertise to accurately rate a home's energy efficiency.

Exam Format

The HERS Rater Exam is composed of two primary sections: a written test and a practical evaluation.

• Written Test: This part consists of 40 to 60 multiple-choice questions, designed to assess general knowledge on home energy rating systems, building science principles, and the interpretation of energy data.
• Practical Evaluation: Candidates are tested on their ability to perform a home energy audit, which includes conducting blower door tests, duct leakage tests, and interpreting field results.

Duration: The written test typically lasts between 2-3 hours, providing ample time to think through scenarios carefully and apply knowledge.

Scoring: To pass the exam, a minimum score of 75% is recommended. Understanding both sections is crucial to obtaining certification.

What to Expect

The HERS Rater Exam emphasizes:

• Building Science Fundamentals: It covers heat transfer, air movement, moisture control, and the principles driving energy efficiency in residential construction.
• Diagnostic Testing: Knowledge of how to set up and interpret blower door tests and conduct duct leakage tests is essential.
• Software Proficiency: Familiarity with energy modeling software is necessary for accurately inputting data obtained from energy audits.
• Regulatory Standards: A solid grasp of energy codes, ratings, and certifications such as ENERGY STAR is required.

Test takers can expect scenarios that require practical application of knowledge, situational analyses, and problem-solving based on real-world data.
