The building we are applying for LEED-EB O&M certification is an office building located on a "campus" with other building facilities. Lamps for the lighting fixtures are purchased by a building management contractor for this campus as a whole and then distributed to each individual building. No tracking mechanism for the purchasing for each individual building is in place; however, the building is set up to track how often a lamp is being replaced and a total count of lamps for each building is available. To track reduced mercury content in lamps we are proposing that a policy be set in place for the campus as a whole to ensure that the inventory of lamps purchased meets credit requirements. In addition, while the actual number of lamps installed in a building is not tracked, we propose that the quantity of lamps is able to be tracked via disposal quantities. Each lamp that is removed from the building is recycled through a hazardous waste management program and inventoried when packaged for disposal. In addition, building changes that result in a change in the total number of lamps in the building will be documented through the respective material purchasing and waste disposal credits and the documents supporting this credit will be updated accordingly.
The project team seeks clarification regarding the use of campus-wide lamp purchasing program to achieve MR Prerequisite 1. The approach described above is adequate to achieve MR Prerequisite 1. However, to be eligible for points under the associated credit (MR Credit 4), the project team must show compliance based on a building-level picogram per lumen hour mercury values stemming from actual installed lamp types and quantities. This requires an inventory of all lamp types and quantities installed within the project building, a purchasing plan based on the inventory demonstrating that lamps models purchased through campus procurement for the project building meet the target mercury content, and evidence that lamps newly installed in the project building during the LEED performance period also meet the target mercury content (the performance period must encompass some lamp replacement activities in order to be eligible for the credit). Without assessing the number and type (e.g., 42" T-8) of lamps installed in the project building, it is not possible to perform the calculations associated with MR Credit 4.
