What type of lighting can be used for 25% or less of the total connected...

In the context of improving indoor environmental quality, specifically regarding lighting, the LEED BD+C guidelines recommend minimizing the use of direct-only overhead lighting to enhance occupant comfort and reduce glare. To achieve this, projects should ensure that no more than 25% of the total connected lighting load for all regularly occupied spaces is composed of direct-only overhead lighting. This approach encourages the use of alternative lighting strategies, such as indirect or diffused lighting, which contribute to a more comfortable and visually appealing environment. ​
