FAQs about MRc2 :

The project building includes a significant amount of process lighting. Do these lamps need to be included?

I can’t find mean lumens on the manufacturer documentation. What should I do?

Do lamps purchased for task lighting need to be included in my calculations?

How should I account for LED purchases? Do I have to show that the LEDs are as energy efficient as similar mercury-containing lamps?

Our building average is over 70 picograms per lumen hour for installed lamps. Do we have to replace lamps before they’ve reached the end of their useful life in order to reach the credit threshold?

Is there a minimum number of lamps that need to be purchased during the performance period in order to achieve this credit?

We purchase lamps for some of our tenants, but not all of them. Can lamps for these tenant spaces be excluded?

EBOM-v4 MRc2:Purchasing - lamps

CI v4: Project only uses LED lighting - still need calculator?

Hello, 

We are attempting this credit for an Innovation point for a v4 CI project. Within the CI scope, only LEDs have been installed. Is a calculator still required if there are no lamps containing lamps within the scope of the project? Would a copy of the lighting fixture schedule showing all new fixtures to be LEDs + a clarification narrative to indicate this approach be sufficient?

You do not need to submit a calculator.  A copy of the lighting fixture schedule showing all new fixtures to be LEDs + a clarification narrative to indicate this approach will be sufficient to demonstrate compliance with this INc.

Bipin, have you had success with this approach for CIv4 or NCv4 projects? Would a static form need to be uploaded as well?

Yes, this approach is good for CI v4 or NC v4 projects ( This worked for several of our projects). If you have lighting cutsheets from manufacturer, you can submit those as well (but not necessary).  I guess by a static form you mean separate LEED Form for this INc, if yes you do not need that. Just mention you are attempting this INc on generic INc LEED Form.  Hope it helps!

Bipin: For a CIv4 or NCv4 project, is this credit considered exemplary performance since 35 picograms of mercury per lumen-hour performance requirement is based on O+M Materials and Resources credit Purchasing – Lamps exemplary performance threshold? Base O+M credit performance requirement is 70 picograms of mercury per lumen-hour. Or is it a standard CIv4 or NCv4 innovation credit?
