Establish and maintain a toxic material source reduction program to reduce the amount of mercury brought into buildings through purchases of light bulbs.
- Maintain mercury content of all mercury-containing light bulbs below 80 picograms per lumen hour of light output (picogram/lumen hour), on weighted average, for all mercury-containing light bulbs acquired for the LEED project building and associated grounds or tenant space. (The weighted average mercury content of these light bulbs is calculated as described in LEED EB v2.0 MR Prerequisite 2).
Please note that since LEED O+M is a whole building rating system, when attempting an Innovation in Design point for following a LEED O+M prerequisite or credit compliance path the strategy must be applied to the entire project building. For LEED Core and Shell projects please provide a copy of a legally binding tenant sales and lease agreement documentation that the tenants meet the requirement of the LEED O+M strategy.
