Humber/Ontario Real Estate Course 4 Exam Practice

Which of the following is true about an energy audit in Ontario?

1. It is mandated by the Ontario Building Code

2. Includes analysis of air leakage sources and insulation condition

3. Encompasses furnace and duct system analysis

4. Assesses circuit configuration

5. Shows problem areas but lacks remedial advice

6. Requires expertise from electrical engineers

The correct answer is: Includes analysis of air leakage sources and insulation condition

The correct answer highlights that an energy audit includes an analysis of air leakage sources and insulation condition. This is a crucial aspect of energy audits as they are designed to identify areas where energy is being wasted, particularly through drafts and inadequate insulation. By assessing the air leakage sources, the audit can pinpoint specific areas that may need sealing to improve energy efficiency. Insulation condition is also a key component because it directly affects a building's ability to maintain temperature, thus impacting heating and cooling costs. A thorough energy audit will consider the quality and effectiveness of existing insulation, determining whether upgrades or improvements are necessary. Other options relate to specific elements that may be included in energy assessments but do not capture the comprehensive nature of what an energy audit is primarily focused on. For example, while an audit may touch on aspects like furnace and duct system analysis, and problem areas in energy usage might be shown, the thorough evaluation of air leakage and insulation is foundational in addressing overall energy efficiency in buildings. Therefore, selecting this particular statement underscores a vital function of energy audits in promoting energy conservation and efficiency in accordance with best practices in Ontario.
