State Polytechnic of Malang (POLINEMA) has taken a part of a joint action to energy savings. The load profile of POLINEMA has specificity in the intensity of electricity energy (IKE) consumption due to it charachterictic as a vocational higher education. This specificity has caused POLINEMA to have many laboratories and workshops in each building. Energy savings can be done if it is supported by an energy consumption data audit system. The data will be calculated and compared to IKE standart. For that purpose, this research is aimed to design and implement an Energy consumption monitoring device based on Enegry Database Management System (EDBMS). In this research, the energy audits were carried out on the lighting and cooling systems of seven buildings in POLINEMA, namely AB, AC, AD, AE, AF, AG, and AH buildings. After auditing of each building is as follows, the IKE value in the AB building is 30.5 kWh/m2/Year, the AC building is 7.5 kWh/m2/Year, the AD building is 15.2 kWh/m2/Year, the AE building is 24.3 kWh/m2/Year, AF building at 71 kWh/m2/Year, AG building at 79.5 kWh/m2/Year, and AH building at 22.6 kWh/m2/Year. In conclusion is Energy consumption in POLINEMA is classified as efficient where the standard of a building for Commercial/Education is 240 kWh/m2/Year.
