Purchasing - lamps

Possible 1 point


To establish and maintain a toxic material source reduction program to reduce the amount of mercury brought onto the building site through purchases of lamps.





Implement the lighting purchasing plan that specifies an overall building average of 70 picograms of mercury per lumen-hour or less for all mercury-containing lamps purchased for the building and associated grounds within the project boundary. Include lamps for both indoor and outdoor fixtures, as well as both hard-wired and portable fixtures. Lamps containing no mercury may be counted only if their energy efficiency at least equals that of their mercury-containing counterparts.
