The design of an energy audit is the first step in the energy management process to support the 12th SDGs program on responsible consumption and production in achieving energy sustainability. The energy audit plan is applied to the smart classroom equipped with SPEM (Smart Plug Energy Monitoring) by considering thermal comfort based on the results of the CFD simulation using the CLTD calculation approach and finding the proper number and position of the air conditioning location. To maintain the comfortable condition of a smart classroom that has 9.3 m in length, 8.3 m in width, and 3 m in height, and 21-person capacity plus various types of equipment inside with a cooling load of 11364,169 Watt or equivalent to 38776,159 Btu/hour, 2 units of 2 HP air conditioning with a capacity of 19000 Btu/hour per unit are required. EMAS (Energy Audit and Management System) is a program designed by combining the results from CFD calculation concepts with conventional energy audit concepts to calculate Energy Using Intensity (EUI) and find the potential for energy savings while maintaining the thermal comfort of the room continuously in real-time. The ideal position for the smart classroom was determined to be on the south wall, which meets the thermal comfort standards and has 24 out of 27 airflow velocity measurement points that comply with SNI 03-6572-2001.
