I'm not sure if there's been any consideration of offering a similar approach to pin-based CFLs, but I think the main motivation for the screw-based allowance is to make sure this credit doesn't discourage a switch from incandescents to screw-based CFLs. Since that possibility doesn't exist for the pin-based lamps, there's no special allowance. If you do happen to have a lot of pin-based CFLs that are pushing your picogram/lumen hour value up, you can always exclude up to 10% of lamps from the calculations (the credit only requires that you show compliance based on 90% of the lamps, based on the number of lamps).

Thank you Jenny! Encouraging building operators to replace incandescent bulbs to CFL's makes sense. However, the lack of a similar exemption does seem to penalize a project building that specified and installed pin-based CFL's as opposed to incandescent bulbs during design and construction. Exempting 10% is a good suggestion, and the strategy we will most likely employ. Thanks again for your comments. They were helpful.

Drew, so did you just end up excluding the pin-based CFL's? We are facing the same problem for our project, and I was just wondering what you ended up doing for documentation.

Richard, I just saw your post from July! So this reply may be too late to be of much assistance. The project included 100% of the pin-based CFL's and was still able to achieve this credit. We worked with the operating team and two different lighting vendors, who competed to see who could maximize the mercury reduction given the existing lighting fixture and lamp schedule.

Hi Drew, No worries, thanks for the input though. We ended up including the pin-based CFL's and were also able to make the credit. So everything ended up fine. Thanks again
