First, let's restate the question and the answer choices to set the context for evaluation.
Question: According to the study, how did the 5-Star homes energy use performance compare with lower rated homes in the winter months?
Answer options:
- a. Their efficiency was about the same
- b. They were more efficient
- c. They were less efficient

Now, evaluate each option in turn with reasoning:
Option a: 'Their efficiency was about the same.' This would imply no meaningful difference in energy performance between 5-Star homes and lower-rated homes during winter. However, the study findings typically show higher-rated homes perform better in cold conditions due to better insulation, tighter envelopes, and superior windows or mechanical systems. Therefore, this option misrepresents the expected difference and is unlikely to be correct.

Option b: 'They were more efficient.' This aligns with common energy performance patterns in winter months, where higher-rated homes (5-Star) generally use less energy to maintain comfortable indoor temperatures thanks to better insulation, reduced air leakage, and more efficient heating equipment. Interpreting the study in this way fits the standard evidence that energy performance improves with higher ratings in cold weather.

Option c: 'They were less efficient.' This would suggest that 5-Star homes use more energy in winter, which contradicts the premise of energy efficiency ratings and typical findings that higher-rated homes perform better in terms of energy use. This is inconsistent with the core idea of rating systems designed to reward lower energy consumption.

Putting these analyses together, the option that best matches the expected study outcome is that 5-Star homes were more efficient in winter months, while the other two options either claim no difference or the opposite of the expected trend. The line of reasoning above highlights why option b is the correct interpretation and why options a and c are incorrect due to mischaracterizing or reversing the typical relationship between energy rating and winter performance.
