Title 24 instead of ASHRAE in CI 2.0

I do not have any experience with trying to use a newer version of LEED to document a project registered under an older version. However, in both LEED CI 2.0 and LEED CI 2009, Credit 1.1 Optimize Energy Performance, Lighting Power only evaluates the connected lighting load or Lighting Power Density (LDP). Getting credit for Daylighting Controls falls under LEED CI 2.0 & 2009 Credit 1.2 Optimize Energy Performance, Lighting Controls. The requirement for CI 2.0 Credit 1.2 is, “Install daylight responsive controls in all regularly occupied spaces within 15 feet of windows and under skylights.” In LEED CI 2009, lighting controls are still covered in Credit 1.2, but there are 3 point available. Two possible points for daylight controls and one for occupancy sensor controls. I hope this helps answer the question.

Dane, We have a CI project where they are using daylight responsive controls in some non-regularly occupied spaces (the central corridors) to reduce lighting loads. That won't count for credit 1.2... do you think we could take the credit for that energy reduction in EAc1.1? Or is this one of those good things to do as a practical matter that doesn't have a tidy fit in a particular LEED credit?

Hi David, The 2nd point available under EA Credit 1.2 gives credit for "Daylight Controls for 50% of the Lighting Load". This applies to the entire lighting load, including non-regularly occupied spaces. If you have enough spaces with access to daylight and with daylight controls installed, then you may qualify for this point. Lighting controls do not apply to EA Credit 1.1, which only addresses Lighting Power Density.

Thanks for the help, Dane.
