FAQs about MRc4 :

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?

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?

CCFL- Cold Cathode Fluorescent Lamps could be excluded from the calculations? The manufacture just inform this:"Low content of mercury, 20% less than that of CFL. How should I proceed?

Luis, I don't see how you could exclude CCFLs. Among mercury-containing lamps, only screw-base CFLs are allowed to be ignored.
