when I have an addition project do I have to demonstrate compliance for the new addition and renovated areas or does it have to be applied to all areas? (existing to remain, renovated and new)

Hi Catalina,
The requirements state that 90% of all lamps purchased during the performance period must have an average of 90 picograms of mercury or less per lumen hour. This credit does not address lamps that were already installed in the building, only lamps purchased during the performance period. If your addition happened during the performance period, then yes, you would have to demonstrate compliance with all lamps purchased for the addition, but only if those purchases were during the performance period. If no lamps were purchased during the performance period, you can't earn this credit.
Hope that helps!
