Red Seal Insulator (Heat and Frost) Practice Exam

How can you improve energy efficiency in homes without major renovation?

1. By upgrading insulation levels in attics, walls, and basements

2. By installing solar panels on the roof

3. By changing windows to triple-glazing

4. By using more energy-efficient appliances

The correct answer is: By upgrading insulation levels in attics, walls, and basements

Upgrading insulation levels in attics, walls, and basements directly enhances a home's energy efficiency without requiring extensive renovations. Improved insulation minimizes heat loss in the winter and heat gain in the summer, leading to a more temperature-stable environment. This not only helps reduce energy consumption for heating and cooling but also improves overall comfort levels within the home. In contrast, while installing solar panels, changing to triple-glazing windows, or using more energy-efficient appliances can all contribute to energy savings, they often involve significant upfront investments or extensive modifications to existing structures. Insulation upgrades are typically less intrusive and can be achieved with relatively minor adjustments or installations, making them a more practical solution for many homeowners looking to improve energy efficiency without embarking on major renovations.
