BPI Energy Auditing 4

Question 1

What instrument does a BPI auditor use to detect moisture in building materials without invasive sampling?

Accepted Answer

Moisture meter (pin or pinless)

Answer

Moisture meters measure electrical resistance or capacitance in building materials to identify elevated moisture content without destructive testing.

Question 2

In a home energy audit, a 'thermal bridge' most commonly refers to which condition?

Accepted Answer

A highly conductive building component that bypasses insulation

Answer

A thermal bridge is a conductive element such as a metal stud or concrete beam that allows heat to bypass surrounding insulation.

Question 3

What does ASHRAE Standard 62.2 govern in the context of residential energy auditing?

Accepted Answer

Ventilation and acceptable indoor air quality for low-rise residential buildings

Answer

ASHRAE 62.2 establishes minimum ventilation rates and indoor air quality requirements for low-rise residential buildings.

Question 4

Which of the following best explains why 'negative air pressure' in a combustion appliance zone is a safety concern?

Accepted Answer

It can cause appliances to backdraft, pulling combustion gases into living spaces

Answer

Negative pressure in the CAZ can overwhelm the appliance's draft, reversing flue gas flow and introducing CO and other combustion products into the home.

Question 5

A homeowner complains of condensation on interior window surfaces in winter. What is the most likely root cause from an energy auditing perspective?

Accepted Answer

High indoor relative humidity combined with low window surface temperature

Answer

Condensation on windows occurs when interior glass surface temperatures fall below the dew point of the indoor air, indicating high humidity relative to the window's thermal performance.
