What is an assessment of energy use in a home to evaluate energy consumption?

• A. Energy Star Rating
• B. Energy Performance Certificate
• C. Home energy audit
• D. Energy Management Plan

Answer: (C)

A home energy audit specifically examines how energy is used in a residence and identifies where consumption can be reduced. It looks at the building envelope (insulation, air leaks, windows), the efficiency of heating and cooling systems, water heating, lighting, and major appliances, often using utility data and some diagnostic tools. The result is a detailed report that outlines where energy is wasted, prioritized improvement recommendations, and estimated savings or payback. This makes it the best choice for an assessment of energy use because it focuses on current consumption and practical steps to lower it.

Energy Star Rating provides a label indicating a level of efficiency but isn’t a full, personalized assessment of how energy is used in a specific home. An Energy Performance Certificate offers an overall efficiency score for a building, which is informative but not the hands-on diagnostic that identifies exact energy-use patterns and improvement opportunities. An Energy Management Plan is a forward-looking plan for reducing energy use, not the actual evaluation of current energy consumption.
