How many credits are available for IAQ Daylight in all other projects?

For the Indoor Environmental Quality (IEQ) credit regarding Daylight in LEED V4, there are a total of two credits available for projects seeking to enhance indoor daylighting. The provision allows projects to earn one credit for achieving a daylight factor in a specified percentage of spaces, typically focused on regularly occupied areas. An additional credit can be obtained by providing a certain level of daylight illuminance to further support occupants’ connection to daylight and outdoor views.

This dual credit structure incentivizes design strategies that prioritize natural lighting, which can lead to improved occupant health and well-being. Projects aiming to optimize daylighting strategies can significantly enhance the quality of the indoor environment, aligning with LEED’s objectives to create healthier, more sustainable buildings. Therefore, the correct understanding of the number of credits available clarifies that there are indeed two credits available in this category for all other projects in LEED V4.
