Ashrae 90.1 the standard for EA1.1 seems to govern only "permanently installed fixtures". I'm taking that to exclude desk lamps. If so is it kosher to reduce installed lighting to get credits under EA1.1 and provide desk lamps to earn IEQ6.1 without counting them in the LPD for EA1.1?

Hi Christopher,
Interestingly enough, this came up recently for one of our projects.
My understanding is that you are correct. It's a little different in California. In CA, I am told that Title-24 2005 requires you to include task lights in your LPD calculation.
I think it meets the intent of EAc1.1, in general, to provide a lower LPD with the use of task lights. Page 155 of the LEED-CI Reference Guide actually notes that task lighting may be used to supplement general lighting. On a side note, I think EAc1.4 is intended to address the plug loads but unfortunately only includes equipment and appliances.

While in the past we were able to not include task lighting for some projects, this is no longer the case. Task lighting must be included unless occupancy sensors are provided.

No, Christopher. I have just been denied EA cr1.1 until I provide additional information on all of the "permanently installed" task lighting to be used in the space. Although I would have understood this in order to maintain consistency with EA cr6.1, we did not claim the task lighting under that credit either. So you need to do it either way.

Hi Amanda,
Does it mean that all task lighting that is submitted for IEQ 6.1 should also be included in the LPD calculation for EA Cr 1.1 even if it is table lamps (plug load and not fixed task lighting) ?
Please advice.
