Certified Energy Auditor Practice Exam

Which is a recommended practice for creating energy-efficient buildings?

1. Maximize the number of windows

2. Use incandescent lighting

3. Implement thermal planning based on sunlight

4. Minimize insulation levels

The correct answer is: Implement thermal planning based on sunlight

Implementing thermal planning based on sunlight is a recommended practice for creating energy-efficient buildings because it maximizes the natural heating and lighting benefits of solar energy while minimizing the need for artificial lighting and heating. This practice involves strategically placing windows, overhangs, and shading devices to optimize solar gain during the colder months and reduce it during warmer months, thus enhancing the overall energy performance of the building. To clarify the context surrounding the other choices, maximizing the number of windows could lead to increased heat loss in colder climates and excessive heat gain in warmer climates if not properly planned. Using incandescent lighting is not energy-efficient compared to other lighting options like LED or fluorescent lights, which consume significantly less energy and last longer. Minimizing insulation levels directly contradicts energy-efficient design principles, as adequate insulation is essential for reducing energy loss and maintaining comfortable indoor temperatures.
