Cutting Energy Cost

• Retrofit Lighting

2
Learning About Your Lighting

• Things You May Already Know
• Its necessary for daily operation
• It impacts productivity and mood
• It becomes more costly as lighting components age

3
Learning About Your Lighting

• Stat-Facts
• Lighting Consumes about 15 of the electricity in
  the United States
• On average, Lighting accounts for 39 of a
  commercial buildings electricity cost
• Newer lighting technology can reduce these costs
  by 30 50

Fluorescent Lighting

Components of Operation
Electrical Feed
Ballast
Fluorescent Tubes
5
Components of Operation

• Fluorescent Lighting Is generally compatible
  with two different types of alternating current
  feeds.
• 277v
• 120v
• note twice the voltage half the amps

Electrical Feed
6
Components of Operation

• Ballast
• A magnetic or electronic voltage
  transformer/regulator that acts on the
  fluorescent tubes contents
• Older Ballasts use electromagnetic coils to
  amplify regulate the AC current
• Newer ballasts use microprocessors, resistors,
  transistors to perform the same function
  at about half the energy usage

7
Components of Operation
Fluorescent Tubes

• Glass tubes of many shapes and sizes that
  contain electrodes, a small amount of mercury,
  argon gas, and a phosphor powder coating
• Differences in tubes, aside from shape include
  lighting color, intensity, and wattage
• These effects are created by changing factors
  like the type phosphor coating on the inside of
  the tube

Components of Operation
Light Putting Them Together

• The electrical feed supplies a voltage to the
  ballast
• The ballast regulates and raises the voltage to
  the electrodes in the fluorescent tube
• The electrodes then create heat which raises the
  energy state of the mercury
• In returning to its original energy state, the
  mercury emits photons of UV light
• The UV light photons raise the energy state of
  the phosphor powder which then emits photons of
  visible light

What is A Retrofit?

• By definition a component or accessory added to
  something after it has been manufactured
• A lighting retrofit then consists of removing
  existing lighting components, and replacing them
  with newer technologies that
• Are less costly to maintain
• Are More energy efficient
• Offer a better quality of light

How Does it Work?

• One of our skilled auditors will take an
  assessment of your lighting system
• A comprehensive count with and type of fixture
  and type of area covered
• A measure of power used
• A before and after estimate of cost and savings

13
How Does it Work?

• Our production team will convert the lighting at
  your facility to accommodate energy efficient
  technologies
• This process could take just a few weeks to a
  couple of months depending on facility size and
  complexity of lighting
• Typical payback period for a retrofit project is
  around 2-5 years

14
In Conclusion

• Lighting amounts to 39 of a commercial
  facilitys electricity expense
• Current technologies can be utilized to reach
  goals of 30-50 savings on lighting cost
• A lighting retrofit is a smart way to adapt these
  energy-saving technologies in a short period of
  time
• The payback period for a retrofit job is
  typically 2-5 years
