What common defects can a HERS Rater identify during an assessment?

The identification of insufficient insulation, damaged ductwork, and faulty windows during a HERS assessment is crucial for evaluating a home's energy performance. These areas significantly impact the energy efficiency of a home and contribute to potential heat loss or gain, affecting overall energy consumption and comfort levels for the occupants.

Insufficient insulation can lead to higher energy bills, as heat escapes in winter and enters in summer, forcing HVAC systems to work harder. Damaged ductwork may cause air leaks, resulting in uneven heating or cooling and reduced efficiency. Faulty windows, including those that are single-pane or have damaged seals, can also be a significant source of thermal bridging and energy loss.

Focusing on these specific areas allows HERS Ratters to provide effective recommendations for improvements, which can enhance the home’s energy efficiency, comfort, and overall performance. This targeted approach addresses some of the most common and impactful defects found in residential energy assessments.
