Abstract: The use of Energy that is in accordance with the planned can be said to be effective and efficient, only can be known through the activities of what is called the Energy Audit. The Energy Audit can be passed in two stages, namely the initial energy audit and detailed energy audit. Initial energy audits are usually carried out on existing data without being inputted with system measurement activities. Detailed energy audits are carried out through the stages of measuring inputs and outputs on energy components and utilities such as refrigeration, lighting, transport utilities and energy users' equipment, both electricity and other types of energy. By referring to the Indonesian National Standard, what energy use can be said to be efficient or not. From the activity of this energy audit it is known that the Energy Consumption Index in buildings is = 19 kWh / m / month or = 228 kWh / m2 / year; according to the Standard classified as Quite efficient., it is known that the profile of energy use that gives a description of the percentage of utility in consuming energy, then it can be known that energy-saving opportunities to be considered are then a priority for implementing energy saving projects.
Keywords: Energy efficiency, Index of energy consumption energy saving, Energy, profile.
