Certified Energy Auditor Certification Certified Energy Auditor Building Envelope Assessment Questions and Answers 3

Question 1

When performing a visual inspection of a building envelope, which indicator most strongly suggests air leakage at a wall-to-ceiling junction?

Accepted Answer

Dark staining or dust marking patterns on ceiling surfaces near walls

Answer

Peeling exterior paint near the roofline

Answer

Hairline cracks in interior drywall

Answer

Efflorescence on exterior masonry

Question 2

An energy auditor is evaluating window performance in a 1990s commercial building. Which measurement best characterizes the thermal performance of the existing window assemblies?

Accepted Answer

The U-factor of the entire window assembly including frame

Answer

The visible light transmittance rating

Answer

The solar heat gain coefficient alone

Answer

The air infiltration rate of the HVAC system

Question 3

Which building envelope deficiency is most effectively identified using a smoke pencil during a depressurized blower door test?

Accepted Answer

Specific air leakage pathways at penetrations and joints

Answer

Insufficient wall insulation thickness

Answer

Thermal bridging through structural members

Answer

Moisture trapped within wall cavities

Question 4

In a hot-humid climate zone, where should the vapor retarder be placed in a wall assembly to minimize moisture condensation risk?

Accepted Answer

On the exterior side of the insulation

Answer

On the interior side of the insulation

Answer

On both sides of the insulation

Answer

A vapor retarder should not be used in hot-humid climates

Question 5

An energy auditor measures a wall assembly and finds the installed cavity insulation has an R-value of R-13, but the overall wall has an effective R-value of R-9.8. What is the most likely primary cause of this performance gap?

Accepted Answer

Thermal bridging through wood framing at 16-inch on-center spacing

Answer

The insulation has degraded due to age

Answer

The drywall is reducing insulation effectiveness

Answer

The exterior cladding is absorbing heat

Question 6

Which method provides the most accurate whole-building air leakage measurement for a large commercial building where a single blower door is insufficient?

Accepted Answer

Using multiple blower doors simultaneously in a multi-point test

Answer

Estimating leakage based on building age and construction type

Answer

Relying solely on infrared thermography

Answer

Calculating leakage from HVAC supply and return airflow measurements
