Abstract
Energy Audit to Improve Energy Consumption Efficiency in Building D Bank Indonesia, Electrical energy is one of the most important necessities of life for humans. Various human activities require electrical energy. Likewise, the activity in the D building which is one of the buildings in the Office Environment Bank Indonesia (KOPERBI) requires electrical energy is very large. Electrical energy is supplied from PLN 9,500 kVA connected power and back-up generator 5 x 1,500 kVA, equivalent to 7,500 kVA. Distribusui use electrical energy as follows: 8.56% lighting load, air conditioner (AC) 67.72% and 23.72% other building equipment. IKE standard used in Indonesia is the result of research conducted by ASEAN USAID in 1987 that a new report issued in 1992, which for the office's value is 240 kWh / m2 per year. IKE Building D BI is as follows IKE Initial Energy Audit is 250.03 kWh / m2.tahun, IKE Detailed Energy Audit is 239.81 kWh / m2.tahun, IKE Phase 1 After Implementation PHE is 224.02 kWh / m2 .tahun, IKE Phase 2 After Implementation PHE is 219.06 kWh / m2.tahun. Electrical energy consumption in Building the jakarta.

PENDAHULUAN Krisis energi dalam dasawarsa terakhir ini menjadi sorotan semua negara
Intensitas Konsumsi Energi (IKE) standard used in Indonesia is the result of research conducted by ASEAN USAID in 1987 that a new report issued in 1992, which for the office's value is 240 kWh / m2 per year
IKE Building D BI is as follows IKE Initial Energy Audit is 250.03 kWh / m2.tahun, IKE Detailed Energy Audit is 239.81 kWh / m2.tahun, IKE Phase 1 After Implementation Peluang Hemat Energi (PHE) is 224.02 kWh / m2 .tahun, IKE Phase 2 After Implementation PHE is 219.06 kWh / m2.tahun
Summary
Jika dilakukan analisis dari diagram pemakaian energi di Gedung D Bank Indonesia dapat ditarik kesimpulan bahwa biaya konsumsi energi terutama energi listrik cukup besar yaitu sebesar 97% dan menempati posisi pertama dalam biaya pemakaian energi yang ada di Gedung D Bank Indonesia dibandingkan biaya konsumsi energi yang lain. Menghitung IKE Dari data konsumsi energi dan data luasan bangunan serta tingkat occupancy rate di gedung, maka dapat dihitung besarnya Intensitas Konsumsi Energi (IKE) Gedung D Bank Indonesia selama satu tahun dengan periode bulan September 2014 s/d. Berdasarkan perhitungan di atas dapat diperoleh besarnya IKE listrik mula-mula per satuan luas adalah 250,03 kWH / m2 year. Sedangkan target IKE per satuan luas untuk perkantoran adalah 240 kWH / m2 tahun (standar IKE ASEAN-USAID tahun 1992). IKE Gedung D Bank Indonesia lebih besar daripada target IKE listrik. Oleh karena itu diperlukan Audit Rinci untuk melihat besar IKE yang lebih nyata atau mendekati sistem
