Energy Efficiency Essentials
A Lighting Retrofit is the Biggest Bang for Your Buck
Lighting (Interior & Exterior)

Domestic Water (Cold) Consumption (Bathroom, Sinks/Toilets)

Hot Water (Tanks & Boilers) Systems (Kitchens, Industrial Processes)

Building Envelope (“Skin”, Roof, Windows, Insulation)

Mechanical Systems & Controls (Conventional or Geothermal)

Appliances (Copiers, Refrigerators, Computers)

Window Film (Solar Gain)

Waste Heat Recovery

Energy Efficient Design
Lighting Retrofit Value
Reduce operating costs
Reduce HVAC “load”
Reduce maintenance
Reduce Carbon Footprint
Interior Lighting
Fluorescent Retrofit
Dim, Photocontrol, Delamp


Reflectorize

Replace T12 lamps with T-8s or LEDs

Add Occupancy Sensors

Replace Magnetic Ballasts with Electronic

Lighting Retrofit Examples
Bibb County Court House in Macon, GA
210,000 sq. ft. Courthouse Complex
Cost savings--$30,000 in five months
Energy usage decreased by over 20%
1.4 year Return On Investment

Interior/Exterior Lighting
Replace old HID technology & curtail exterior lighting (less light
pollution, less wasted energy) Options: LED & Induction

Reduce Wattage of Fixtures

Dim and Photocontrol Using Wireless Technology

Lighting Retrofit Examples
Use Less Power, Shed More Light

Georgia Power Ally Program
Commercial Facilities Meeting the Program Criteria
May be eligible for federal or state tax incentives.
Incentive program provides the following incentives to participating facilities:
Commercial facility
Taxable--$0.05/kWh$5,000
Tax exempt--0.05/kWh$10,000
Incentives consist of a one-time payment based on first year energy savings.
Savings baselines will be based on:
Current state and local code requirements
Current industry practices for replacement and new construction
measures.
*Georgia Power will reserve the right to exercise discretion and adjust baselines for retrofit
projects affecting measures significantly before the end of their useful life or for measures
where codes and/or current industry practices are not applicable.
Georgia Power Ally Program
Existing Building Custom Lighting
Measure 1: Fluorescent Lighting fixtures.
Fixture must be listed on Consortium for Energy Efficiency website
This site covers only 4' T8 lamps and ballasts.
17w, 2' T8 lamps must have a minimum efficacy of 75 mean lumens/watt.
32w, U-bend T8 lamps must have minimum efficacy of 79 mean lumens/watt.
T5 lamps are also eligible under this measure.
Measure 2: High Bay Lighting.
All high bay lighting must be pulse start HID technology or high efficient fluorescent.
Measure 3: Other lighting.
This consists of lighting fixtures not included in Measure 1 or Measure 2.
Common to this category is LED lighting, which must meet ENERGY STAR standards,
Other lighting sources and fixtures may qualify but will need to be pre-approved.
Together We Make a Difference
with Energy Efficient Lighting
