What type of lighting control adjustment is encouraged for LEED projects aiming at energy efficiency?

Automated adjustments based on real-time data are encouraged for LEED projects aiming at energy efficiency because they dynamically respond to current conditions, such as occupancy levels and natural daylight availability. This type of lighting control helps in optimizing energy use, reducing waste by ensuring that lighting is only provided where and when it is needed.

For example, lighting can be reduced in areas that are unoccupied, which minimizes energy consumption without sacrificing comfort. Additionally, these systems can adapt to changes in daylight, adjusting artificial lighting levels to maintain consistent illumination without over-lighting a space. This not only supports energy efficiency but also contributes to better occupant satisfaction and overall building performance, aligning with LEED's goals.

Manual dimming, while it allows for personalized control, relies heavily on occupant engagement and can lead to inconsistencies in energy savings if not used effectively. Fixed lighting levels do not account for variations in natural light or occupancy, resulting in unnecessary energy consumption. Constant full utilization of lighting during operational hours disregards opportunities for efficiency and fails to leverage technology that can enhance energy performance.
