BAP Energy & Building Performance — Questions and Answers
Question 1: What is the primary benefit of air sealing in a building?
- Increases air leakage
- Reduces energy loss and improves comfort (Correct answer)
- Eliminates the need for insulation
- Reduces the need for ventilation
Correct answer: Reduces energy loss and improves comfort
Air sealing reduces drafts, increases energy efficiency, and improves indoor air quality by preventing uncontrolled airflow.
Question 2: Which building component has the greatest impact on thermal performance?
- Roof shingles
- Wall insulation (Correct answer)
- Paint color
- Window blinds
Correct answer: Wall insulation
Insulation plays a critical role in reducing heat transfer, improving energy efficiency, and maintaining indoor comfort.
Question 3: What is the purpose of a blower door test?
- To measure humidity levels
- To assess air leakage and building tightness (Correct answer)
- To check for mold growth
- To inspect the HVAC system
Correct answer: To assess air leakage and building tightness
A blower door test measures air leakage in a building, helping to identify areas where energy efficiency improvements can be made.
Question 4: Which factor is most important in selecting energy-efficient windows?
- Window frame color
- U-factor rating (Correct answer)
- Glass thickness
- Shape of the window
Correct answer: U-factor rating
The U-factor measures a window's insulation ability, with lower values indicating better energy efficiency and heat retention.
Question 5: What is the benefit of using LED lighting over traditional incandescent bulbs?
- Uses more electricity
- Consumes less energy and lasts longer (Correct answer)
- Requires more maintenance
- Produces excessive heat
Correct answer: Consumes less energy and lasts longer
LED lighting consumes significantly less energy, has a longer lifespan, and generates less heat compared to incandescent bulbs.
Question 6: Which HVAC system feature improves indoor air quality while maintaining energy efficiency?
- Traditional exhaust fans
- Energy recovery ventilators (ERVs) (Correct answer)
- Window air conditioners
- Portable humidifiers
Correct answer: Energy recovery ventilators (ERVs)
Energy recovery ventilators (ERVs) provide fresh air while minimizing heat loss, improving both efficiency and indoor air quality.
