The project does not need to achieve MRc1.1:  Building Structure Reuse to pursue MR 1.2: Building Nonstructural Reuse.

Determine whether the project is eligible for the credit based on existing floor area and total floor area. A project is eligible if the project is reusing an existing structure and there is no new addition or the new construction that is no more than two times the gross floor area of the existing floor area.

In multi-tenant buildings, collect lamp purchasing data from tenants and verify that each purchase complies with the purchasing plan.

In-house staff can handle lamp inventory and purchasing data tracking and documentation at minimal added cost.

A custom mercury content calculator will be denied by the LEED reviewer and should not be submitted as part of your LEED application. If a custom calculator or tool provided by a manufacturer was used during the performance period, all required data must be transferred to the built-in calculators in Table 1.1 and Table 1.2 of the LEED Submittal Template.

Cut sheets do not always clearly display the three pieces of data you need to complete the submittal tables. Here are some tips:

“Rated Average Life”: For fluorescent lamps, make sure to use the value for the three-hour instant start.
“Mean Lumens”: Make sure to use the value for “Design Mean Lumens.” Do not use the value for “Initial Lumens” unless the manufacturer does not provide a value for the mean lumens.
Sylvania Lighting provides a LEED-EBOM calculator on its commercial website that may be used as product documentation for mercury content.

Provide manufacturer cut sheets for at least 20% of the total number of lamps purchased during the performance period, for the LEED submittal. Make sure that the cut sheets clearly indicate the specific lamp description or code and the rated picogram/lumen-hour, or the rated mercury content, mean lumen output, and rated life.

Mercury-containing lamps (or their high-efficiency counterparts) must be purchased during the performance period to qualify for this credit. In other words, if no lamps are purchased during the performance period, you will not be able to achieve the credit, even if you’ve developed a good purchasing plan.

Track all lamp purchases and verify that the weighted average mercury content of purchased lamps meets the target specified in the purchasing plan

If more than 10% of the building floor area is occupied by tenants who are unwilling or unable to share information about currently installed lamps, the project team is allowed to extrapolate existing data for the purchasing plan in order to complete a plan that covers at least 90% of the lamps in the building and associated grounds.
