Which of the following could a HERS rating not cover for homeowners?

The Home Energy Rating System (HERS) focuses on quantifying energy efficiency in residential buildings. This includes evaluating aspects such as insulation, HVAC (heating, ventilation, and air conditioning) systems, and energy-efficient appliances, as these elements have a significant impact on a home's energy consumption. Each of these choices plays a crucial role in contributing to a home's overall energy performance.

Landscaping options for aesthetics, however, fall outside the scope of the HERS rating. While landscaping can influence a home's energy usage indirectly—such as through the strategic planting of trees for shading or windbreaks—these enhancements are primarily related to visual appeal rather than direct energy efficiency measures considered in HERS evaluations. Consequently, they do not directly affect the HERS score in the same way that appliance efficiency, HVAC improvements, or insulation upgrades do. Thus, HERS ratings do not cover landscaping options primarily aimed at aesthetic improvements.
