Which of the following features is considered a minimum rated feature of a home?

Air infiltration is deemed a minimum rated feature of a home because it directly influences energy efficiency and indoor air quality. This concept refers to the uncontrolled exchange of outside air with indoor air through cracks, gaps, and openings in a building's envelope. A home should ideally have a controlled level of air infiltration to minimize energy loss and enhance comfort while maintaining a healthy indoor environment.

Managing air infiltration is critical in achieving energy efficiency standards, as excessive air leakage can lead to increased heating and cooling costs. Thus, it is a key focus area in the Home Energy Rating System (HERS) assessments, where monitoring and improving air sealing measures is essential for meeting energy performance benchmarks.

While features like exterior landscaping, roof shingles, and interior paint may contribute to the overall aesthetics and functionality of a home, they do not play a direct and critical role in energy performance standards as air infiltration does. Therefore, air infiltration is categorized distinctly as a minimum rated feature because of its significant impact on the home's energy efficiency rating.
