Hi,
We've only done the mechanical portion for this project but the client assigned to us the EAc1 credits. So, we're just coordinating whatever electrical information we need to complete the form. I asked the assigned engr. for their daylighting and other lighting controls (design/baseline) and he said we could declare "NONE" since there is no credits claimed for this project. By the way, i shared email below for his reasons:
" These were not claimed previously on the T24 due to the fact that the project had beaten T24 requirements by 47% even without lighting control credits. Further, as you implied, the purpose of form EAC1 Table 1.4, is to compare between the proposed and baseline models, so "none" will still be the correct response to the baseline portion of both day lighting and other lighting control credits (as our design portion will only list the claimed credits). I do not have all of the information I need to calculate the effective aperture of the exhibit and classroom areas (where the automatic day lighting controls are located), so I am unable to give you the day lighting control credits at this time".
Is this acceptable or i believed we should provide info under this field and if they don't have any lighting controls, how can they passed their T-24? I'm not a technical person, and just want to clarify.. for every design, is daylighting or lighting controls always included?
Appreciate any inputs.
Regards,
Susan

If it's not in the building, it shouldn't be in the model. If it's not in the model, it shouldn't be on the Credit Form. You should only call out lighting controls beyond what is required by ASHRAE 90.1. In most cases you can't claim credit for occupancy sensors.
Daylight responsive lighting certainly does not become part of every design.
