AUDIT ENERGI DAN ANALISIS PELUANG PENGHEMATAN ENERGI LISTRIK PADA SISTEM PENGKONDISIAN UDARA KANTOR PUSAT ADMINISTRASI POLITEKNIK NEGERI LHOKSEUMAWE

Abstract

This research was conducted at the main office administration building (KPA) of Lhokseumawe State Polytecnic to audit the use of energy and to analyze the possibilities of electrical energy saving opportunities in the building. The method used in the research is six sigma method with DMAIC (Define, Measurement, Analyze, Improvementdan Control) by not ignoring the level of comfort with National Standards of Comfort (SNI). From the research, it was found that the value of the intensity of energy consumption (IKE) of KPA is 186.44 KWH/m².year, the rate is higher than IKE of developed countries  have implemented to inferior building energy consumption which is below 150 KWH/m².year. If it is referred to IKE standard, then the use of energy in KPA building is inefficient. The measurement showed that the burden of cooling actual averege reached 14 .472,73 Watt.hour. The result of analysis found that there has been an overload cooling load on STU system building. On the space of improvement set, some solutions for repairing of categorial air system can be done by minimizing the factors that caused  over cooling load , the result of repairs showed a load of cooling which is 10.970,33 Watt.hour and it means the savings did happen for 3502,4 Watt.hour or 24,2 %, or per mounth the electric energy saving reached 963,65 Kwh/mounth or equivalent to 11.563,88 Kwh per year. In the space of control aims to evaluate and monitor the result of the implementation in the grouned in order to be able to maintain the value of burden of cooling at the standard level or needed level
