Complete the Lighting Surveys Below
Pick at least one space in the building that has similar operating hours and use.
Gather the information about the space and complete
the table. Review the calculations below the table and answer questions. Complete all information for at least one space for 25 points.
You may copy rows 3 through 22 to survey additional spaces in your building with different operating hours.

Utility Incentive Research
List the local incentive resources you identified.
In Part II, you will research resources in your city that provide rebate incentive
information including utility companies, websites, government agencies and other
organizations.
Tip! Start with your local utility website, or access www.dsireusa.org database of
Energy Efficiency incentives for your state. HINT: when accessing the database, un-
check the Renewable Energy box to narrow your search results.
List the steps that need to be taken to apply for incentive sponsored energy
efficiency projects before and after they are completed.

ROI
The commercial building in our case example operates 3,000 hours annually and has 250 fixtures with 4 fluorescent
each and electronic ballasts and are rated at 112 watts each.
The lamps are at the end of their life and as the Buildi
Operator you are preparing for a group re-lamping and are asked to research cost and incentive programs for a tubu
retrofit of the existing fixtures. You purchased and tested several LED lamps and have determined that a 17-watt tub
Type A lamp is the best option using 4 lamps per fixture which will reduce the wattage of the fixture to 75 watts eac
(including ballast losses). The project cost is $40/fixture which includes labor and lamp disposal cost. The Electric Uti
company offers a rebate of $1/lamp and the electricity rate for your building is $0.12/kWh.
Complete the green hig
fields based on the case study; grey field contain calculations.
