Question 1: What is the primary purpose of a blower door test in an energy audit?
- To measure air infiltration rates in a building envelope (Correct answer)
- To test the efficiency of HVAC blower motors
- To calibrate ventilation fan speeds
- To measure indoor humidity levels
Correct answer: To measure air infiltration rates in a building envelope
A blower door test depressurizes or pressurizes a building to quantify the rate of air leakage through the building envelope.
Question 2: Which metric represents the total annual energy consumption of a building normalized by its floor area?
- Energy Use Intensity (EUI) (Correct answer)
- Coefficient of Performance (COP)
- Seasonal Energy Efficiency Ratio (SEER)
- British Thermal Unit Rating (BTUR)
Correct answer: Energy Use Intensity (EUI)
Energy Use Intensity (EUI) is expressed in kBtu per square foot per year and allows meaningful comparison of energy performance across different-sized buildings.
Question 3: During an energy audit, what does a thermal imaging camera primarily detect?
- Temperature differences on building surfaces (Correct answer)
- Electrical current flow in wiring
- Carbon dioxide concentration levels
- Sound transmission through walls
Correct answer: Temperature differences on building surfaces
Infrared thermography reveals surface temperature variations that indicate insulation gaps, air leaks, moisture intrusion, and thermal bridging.
Question 4: What is the recommended minimum R-value for attic insulation in US Climate Zone 5 according to IECC guidelines?
- R-49 (Correct answer)
- R-30
- R-13
- R-60
Correct answer: R-49
The International Energy Conservation Code recommends R-49 for attic insulation in Climate Zone 5 to minimize heat loss through the roof assembly.
Question 5: Which of the following is an example of a no-cost or low-cost energy conservation measure an auditor might recommend?
- Adjusting thermostat setback schedules (Correct answer)
- Replacing the entire HVAC system
- Installing a geothermal heat pump
- Adding a building automation system
Correct answer: Adjusting thermostat setback schedules
Thermostat setback scheduling requires minimal or no investment and can reduce heating and cooling energy consumption by 5-15%.
Question 6: What does the term 'base load' refer to in a building's energy consumption profile?
- The minimum constant energy demand regardless of weather conditions (Correct answer)
- The peak electrical demand during summer months
- The energy consumed only by lighting systems
- The total energy used during unoccupied hours
Correct answer: The minimum constant energy demand regardless of weather conditions
Base load represents the consistent energy consumption from equipment that operates continuously, such as refrigeration, servers, and plug loads, independent of heating or cooling needs.
