What do they do?

The Coast Central Credit Union is a financial institution working to provide credit at manageable rates, as well as other financial services, promote thrift and community development in Eureka and the surrounding areas.

The Retrofit

In April 2008 the RCEA retrofitted the Coast Central Credit Union's office space lighting and replaced the existing lights with brighter and more energy efficient light fixtures.

How do they like it?

The retrofit was a great success! "The new lights are wonderful, now it is always bright enough in the office." commented Gerry Lewis durring a phone interview.

Can you see the difference?

In the year before RCEA's retrofit the average kilowatt useage by the coast central credit union was about 2800 KWH each month. After new lights were put in the energy use has been steadily dropping and for the August was at 1360 KWH saving $191 from last August.

Energy saved is clearly visible in this graph.

Actual Savings

Energy

The total energy used in April 2007 to April 2008 was 37,150 KWh. The energy used in April 2008 and April 2009 after the retrofit was 28,960 KWh. The difference of the two gave us the total amount energy saved, 8,200 KWh.

CO2 saved

Using the pounds CO2 per KWh from RCEA's estimation we derived a lb to KWh ratio of .519. We used with the total energy 8,200KWh to calculate the reduction in pounds of CO2 which was 4,255 pounds of CO2.

Money saved
