Report: Proper daylight controls commissioning leads to energy savings

The Energy Center of Wisconsin's report shows that proper daylight controls commissioning can lead to energy savings—often 60% or more.


The Energy Center of Wisconsin's report, Commissioning for Optimal Savings from Daylight Controls, focuses on daylighting control and how it can provide up to energy savings of up to 60% with proper commissioning. 

Daylighting control, or daylight harvesting, has become a common energy savings strategy in many sustainable building projects, but several barriers still prevent successful implementation of this strategy in mainstream construction. Considerable effort is expended in the architectural and lighting design of daylighting controls, with actual execution being an afterthought.

Best practices suggest that a significant commissioning effort is required for daylighting controls to function properly and reach full energy savings potential. While HVAC systems often receive significant attention at this stage, lighting controls and most specifically daylighting controls, generally do not.
