FAQs about MRc4 :

How do you know if a lamp meets the NEMA guidelines, and can therefore be excluded?

The project building includes a significant amount of process lighting (i.e. sports arena lighting or studio lighting). Do these lamps need to be included?

There are no mercury-containing lamps installed in the project building. Can we upload a signed statement from our property manager instead of completing the credit form and documentation?

A large multi-tenant project does not have a uniform lighting standard, therefore there are a number of different types of lamps are installed on the project. How should we go about documenting this credit?

Do we need to provide a purchasing plan if the lamp inventory of currently installed lamps shows that the average mercury content is already below 90 picograms per lumen-hour?

Do lamps for task lighting need to be included in the purchasing plan?

Do mercury-free lamps need to be included in Table MRc4-1 Lamp Purchasing Plan and Table MRc4-2 Performance Period Lamp Purchasing?

All of the outdoor fixtures in the project building are mercury-free. Can we exclude all outdoor fixtures from the purchasing plan?

The project building is a large multi-tenant building and tenants are responsible for their own lamp purchases. Can lamps in tenant spaces be excluded?

EBOM-2009 MRc4:Sustainable Purchasing—Reduced Mercury in Lamps

NEMA compliance

Hi. I am kind of new to this. I was checking if a Spanish building might earn some credits from MRc4. Since I am Spanish and it´s my first experience with LEED, I had not heard before of NEMA or NEMA standards. I just wanted to check that any CFL under 5 mg of mercury content (with less than 25 W) or under 6 mg (between 24 and 40 W) comply with NEMA (and, thus, it can be excluded). I mean that meeting the standard does not need some sort of NEMA label or something similar (like in the case of "energy star" label for electronics), that it is enough wtih being under the thresolds. I hope I made myself clear. Thanks a lot.

I think you've got it - there's not a NEMA label or certification or anything that lamps must have, just that they fall under the mercury thresholds established by NEMA.

Blas, Only CFL's with screw bases and integral ballasts that meet NEMA standards are exempt. These are the kind that replace traditional incandescent lamps in the old fixtures. A newer CFL fixture where the ballast is separate from the lamp and the lamp has pins will require you to meet the listed 90 picogram level average. Expect the mg limits in LEED 2012 to be lowered to the NEMA 2010 level of 4mg and 5mg. http://www.nema.org/gov/env_conscious_design/lamps/cfl-mercury.cfm
