"Mercury-free lamps, such as LEDs, can be included in the picogram per lumen-hour calculations only if they have efficiency levels that are equal to or greater than those of comparable mercury-cont

I found the following life values in the Bulb specifications. Which rated life is to be used in the LEEDOnline form for this credit?

I have scoured the internet for HG content of a few of the CFLs we have in our building with no luck. Let's say I can't find HG content and thus cannot know whether the CFLs meet NEMA guidelines.

This credit requires not only the mercury content of the bulbs, but specific life and light output using specified testing methods: · Life of bulb: 3 hours on/20 minutes off for fluorescent bulbs;

Hi, I'd like to know which kind of luminaire means "exit signs". Does it means the constant light of the emergency lights? Thanks,

Can a v2.2 project get this credit even if its a v2009 credit?

Hello all. I have spent most of this week trying to complete research from the review comments. I have some questions, but also feedback for all of you. 1.

I am pursuing this credit for a CI project as an ID credit. I am wondering, in order to comply with the overall value of 90 pg Hg/(lm*h), I need to include all my LED lamps.

We have over 6,000 lamps in our building, and all but 26 have readily available low-mercury/ high efficiency counter parts. The 26 in question are "mini candelabras" ....

We're working on a LEED Volume prototype for our campus and received this feedback on MRc4: Only up to 10% of the floor area under separate control may be excluded from the calculations, so if resi
