| Abstract: | The purpose of this paper was to present the results of a life cycle cost analysis concerning the purchase and operation of
a more efficient popular refrigerator model compared with a baseline design in Brazil. The summarized results may be useful
for organizations working to promote sustainable energy development. This paper specifically focuses on refrigerators, since
their energy consumption is predicted to constitute over 30% of the total average domestic electricity bill in Brazilian households.
If all new Brazilian refrigerators had an energy efficiency at the level consistent with the least life cycle cost of ownership,
it would result in an annual savings of 2.8 billion dollars (US$) in electricity bills, 45 TWh of electricity demand, and
18 Mt of CO2 emissions, with a respective payback period of 7 years which is less than half the average estimated lifetime of a refrigerator.
The analysis was conducted following the guidelines of similar analyses available from the US Department of Energy and the
Collaborative Labeling and Appliance Standards Program.
