| Summary: | Electrical energy savings become important for the community to reduce
energy consumption. Some ways that can be done is the equivalent replacement of
components that have better efficiency (retrofitting), upgrading of technology
equipment and energy-saving behavioral habituation.
In this study the calculation of the acquisition of savings that can be
obtained by performing the equivalent replacement of components in air
conditioning system and lighting system. Moreover, questionnaire was also
conducted in this study to get the response from the people in JTETI-FT-UGM
about the saving of electrical energy consumption.
The results obtained from this study is that there is on average 5.252,415
kWh (22,4%) per month electrical energy savings opportunities in the air
conditioning system by replacing refrigerant of freon into musicool. The, the
electrical energy savings opportunities could also be obtained from the lighting
system for about 2.320,318 kWh (20,8%) per month by replacing electronic
ballasts and fluorescent lamps. The questionnaire indicate that the behavior of
respondents in JTETI-FT-UGM against the savings in the consumption of
electrical energy is in the category of good. While the time required for return on
investment is 12 months in the air conditioning system and 76 months in the
lighting system.
