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

What percentage of regularly occupied floor area must have direct line of sight to the outdoors via vision glazing for IEQ Credit Views?

1. 50%

2. 75%

3. 30%

4. 100%

The correct answer is: 75%

For the Indoor Environmental Quality (IEQ) Credit related to views in the LEED BD+C rating system, the requirement is that at least 75% of the regularly occupied floor area must have a direct line of sight to the outdoors through vision glazing. Vision glazing typically refers to windows that allow natural light and views to be seen from occupied spaces. The focus on this percentage is to promote visual connectivity to the outdoors, which has been linked to several positive outcomes—such as increased occupant well-being, enhanced productivity, and improved overall comfort. By ensuring that a significant portion of the occupied area has access to views, buildings can provide an environment that is more enjoyable and beneficial for occupants. The specified percentage is designed to encourage the inclusion of windows and open areas in building designs, which not only improve aesthetics but also support the mental health of those occupying the space. Meeting this requirement is a straightforward way for building projects to enhance indoor environmental quality and qualify for additional LEED credits. It is also worth noting that the other percentages listed do not meet the criteria set by LEED, as they fall short of the established target for this credit, underscoring the emphasis LEED places on achieving high standards for visual connection to natural surroundings in building design.
