Sustainable Lighting Index Worksheet

To help you calculate the Sustainable Lighting Index (picograms of mercury per lumen hour — pg/lu-hr) for lighting systems in facilities considering LEED-EB certification, Philips Lighting has created this unique combination worksheet and calculator. A rating below 100.00 is considered to be in compliance with the LEED-EB certification standards.

Simply name an area within your facility. Select the brands and types of lighting used in that area. Enter the number of fixtures for each type and hit the "Calculate" button.

Add more areas until you've covered the entire facility. Then click on "Finish Calculations." A summary report will appear, complete with buttons that will print out a LEED-EB friendly version of the information.

Indicates average mercury content of lamps is over 100 picograms per Lumen-Hour. When selecting OTHER under Brand to manually enter non-Philips products, you will need to input the lamp life, mercury content, and design lumens in order to determine the mercury rating.
