LEED AP Building Design and Construction (BD+C) Practice Exam

Which option is involved in measuring daylight in IEQ Credit Daylight?

1. Thermal simulations

2. Illuminance calculations

3. Energy model simulations

4. Acoustic measurements

The correct answer is: Illuminance calculations

The correct answer involves illuminance calculations because this method is specifically designed to assess the amount of daylight entering a building and the overall quality of the indoor environment in terms of natural light. In the context of the Indoor Environmental Quality (IEQ) Credit Daylight, illuminance calculations provide quantifiable data to demonstrate compliance with prerequisites and credits related to daylight availability. Illuminance calculations help determine the distribution of light within a space, ensuring that adequate levels of natural light are achieved to enhance the comfort and well-being of occupants. This is important for promoting a healthy indoor environment and maximizing the benefits of natural lighting, such as reducing reliance on artificial lighting and improving energy efficiency. Thermal simulations and energy model simulations primarily focus on energy consumption and thermal performance, rather than specifically quantifying daylight or its impact on indoor environments. Acoustic measurements deal with sound levels and noise control, which are not pertinent to the evaluation of daylight within a space. Therefore, illuminance calculations are the logical method for measuring daylight as it directly addresses the criteria established in the credit for daylighting.
