  2. Obtaining accurate information from the building occupants.

  3. Interpreting the results of the audit.

  4. Making recommendations that are specific to the needs of the building.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Making recommendations that are specific to the needs of the building is not a potential challenge in conducting an energy audit of a commercial building, as the auditor will have the necessary knowledge and experience to do so.

Multiple choice

Which of the following is NOT a potential challenge in conducting an energy audit of a residential building?

  1. Gaining access to the building.

  2. Obtaining accurate information from the building occupants.

  3. Interpreting the results of the audit.

  4. Making recommendations that are cost-effective and practical.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Making recommendations that are cost-effective and practical is not a potential challenge in conducting an energy audit of a residential building, as the auditor will have the necessary knowledge and experience to do so.

Multiple choice

Which of the following is NOT a limitation of using a blower door test for an energy audit?

  1. It can be expensive to conduct a blower door test.

  2. It can be difficult to interpret the results of a blower door test.

  3. It can be difficult to conduct a blower door test in windy conditions.

  4. It can be used to identify air leaks in a building.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Blower door tests can be used to identify air leaks in a building, as they measure the amount of air that is leaking in and out of the building.

Multiple choice

Which of the following is NOT a limitation of using an infrared camera for an energy audit?

  1. It can be expensive to purchase an infrared camera.

  2. It can be difficult to interpret the results of an infrared camera inspection.

  3. It can be difficult to use an infrared camera to inspect buildings in cold weather.

  4. It can be used to identify areas of heat loss in a building.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Infrared cameras can be used to identify areas of heat loss in a building, as they can detect the infrared radiation that is emitted by warm objects.

Multiple choice

Which of the following is NOT a limitation of using a data logger for an energy audit?

  1. It can be expensive to purchase a data logger.

  2. It can be difficult to install and maintain a data logger.

  3. It can be difficult to interpret the results of a data logger.

  4. It can be used to track energy consumption over time.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Data loggers can be used to track energy consumption over time, as they can store and analyze historical energy data.

Multiple choice

Which of the following is NOT a common energy audit technique?

  1. Walk-through inspection

  2. Data analysis

  3. Infrared thermography

  4. Energy modeling
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Energy modeling is not a common energy audit technique, as it is typically used for designing new buildings or systems, rather than for auditing existing facilities.

Multiple choice

What is the purpose of an infrared thermography scan in an energy audit?

  1. To identify areas of heat loss

  2. To measure the efficiency of heating and cooling systems

  3. To detect electrical faults

  4. To assess the condition of insulation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Infrared thermography is used to identify areas of heat loss in a building by detecting variations in surface temperatures. This information can be used to identify areas where insulation is inadequate or where there are air leaks.

Multiple choice

Which of the following is NOT a common energy conservation measure identified in energy audits?

  1. Upgrading to energy-efficient lighting

  2. Installing programmable thermostats

  3. Improving insulation

  4. Replacing old appliances with energy-efficient models
