Energi yang digunakan untuk gedung dalam mendukung segala aktivitas umumnya adalah energi listrik. Audit energi listrik perlu dilakukan pada suatu sarana maupun sistem yang telah ada supaya teridentifikasi potensi penghematan energinya. Langkah audit energi listrik di suatu gedung dimaksudkan untuk dapat diketahui pola konsumsi energi listrik, pemborosan yang terjadi dan kemungkinan penghematan yang dapat dicapai sehingga dapat meningkatkan efisiensi penggunaan energi. Audit energi dilakukan dengan mengukur konsumsi energi listrik pada setiap peralatan selama 24 jam, melakukan pendataan terhadap peralatan pengkonsumsi energi listrik serta pendataan terhadap jumlah dan jenis lampu yang digunakan di bangunan gedung toserba yogya ciamis. Pengolahan data dilakukan untuk mengetahui karakteristik penggunaan energi listrik, Intensitas Konsumsi Energi (IKE), serta tingkat efisiensi penggunaan energi listrik bangunan gedung. Besarnya Intensitas Konsumsi Energi (IKE) listrik dapat digunakan untuk menentukan tingkat efisiensi pemakaian energi listrik bangunan gedung toserba. Apabila didasarkan pada suatu standar menurut Pedoman Konservasi Energi dan Pengawasannya di Lingkungan Pendidikan Nasional, maka IKE Bangunan Gedung Toserba Yogya Ciamis dengan jumlah 392.760 kWh/m2/tahun dikategorikan sangat boros, namun masih memiliki peluang penghematan, dengan cara penggantian Refrigeran Freon R-22 oleh Refrigeran Petrozon Rossy-22 serta penggantian lampu dengan ballast elektronik.

Energy used for a building to support all of the activities generally is electric energy. An audit of electric energy needs to be done in an available medium or system in order to identify the economizing of its electricity. The audit step of electric energy in a building is intended to know the consumption pattern of electric energy, the electric wasting that happens and the possibility of economizing that may be achieved therefore it improves the efficiency of energy use. Energy audit is conducted by measuring the consumption of electric energy of every equipment in 24 hours, taking the data on the equipment consuming electric energy, and taking the data on the number and types of lamps used in the building of Ciamis Yogya department store. Data processing is done to know the characteristics of electric energy use, the Intensity of Energy Consumption (IKE), and the level of efficiency of electric energy use in the building. The magnitude of the Intensity of Energy Consumption (IKE) of electricity can be used to determine the level of efficiency of electric energy use of the building of the department store. Based on the standard according to the Guideline of Energy Conservation and Its Control in the National Educational Environment, the Intensity of Energy Consumption (IKE) of the building of Ciamis Yogya department store is as much as 392,760 kWh/m2/year which is categorized into very consumptive, however, there is an opportunity of economizing, by doing the replacement of Freon R-22 with Refrigeran Petrozon Rossy-22 and the replacement of the lamps with electronic ballast.
