World energy consumption was used in several sectors. One of this was building sector that the electricity consumption, higher than other sectors. So as in Indonesia, electrical consumption in the building was higher than other sectors. Electricity consumption also becomes a huge contributor to greenhouse gasses especially carbon. Electricity consumption in Indonesia was getting higher because of human behavior and electrical tools, so it needed a management audit for controlling this problem. This research was studied energy efficiency and carbon reduction from the scenario in educational building which was Universitas Internasional Semen Indonesia building 1 in campus A. This research used energy audit method which decided by 4 main steps plus one, the audit identification process of temperature and lighting in the room, standard of energy used, energy efficiency scenarios and the calculation of carbon emission. The result showed that electricity consumption in UISI is 10.62 kWh/month which quite an energy efficient, while natural lighting (daylighting) and artificial lighting wasn't fulfilling Indonesian standard (SNI). Five energy efficiency recommendations were created to find the most energy-saving : energy efficient behavior, replenishment rubber on the door, the addition of window film, sleep mode on a computer and replace fluorescent lamps with lower wattage were saved 49% from total energy consumption. From the calculation, we get that by implementing five scenarios, it can reduce carbon emission about 11,037 tons CO2 / year.
