ICC Permit Technician Practice Exam

The required energy efficiency inspection specifically includes verifying all the following except:

1. Envelope insulation R-values

2. Duct system R-Values

3. Sealing against air leakage

4. Fenestration U-values

The correct answer is: Sealing against air leakage

The correct answer is that sealing against air leakage is not specifically included in the required energy efficiency inspection. The energy efficiency inspection focuses on assessing measurable aspects that contribute to the overall energy performance of a building. Envelope insulation R-values are a critical part of the inspection because they indicate how well the insulation resists heat flow, directly impacting energy consumption for heating and cooling. Duct system R-values similarly measure the effectiveness of thermal resistance in ductwork, which can significantly affect the energy use in conditioned spaces. Fenestration U-values pertain to the rate of heat transfer through windows and doors, also crucial for energy efficiency, as they play a key role in the building's thermal performance. In contrast, sealing against air leakage, while important for energy efficiency, is often addressed through guidelines and standards rather than as a specific measurable aspect in the context of this inspection. Air leakage can vary significantly based on multiple factors within construction and is typically monitored through testing methods such as blower door tests, rather than being quantified directly in the inspection. Therefore, while sealing against air leakage contributes to energy conservation goals, it is not one of the targeted components to verify in the energy efficiency inspection.
