Under the support from the Islamic Development Bank (IDB), Universitas Negeri Malang (UM) is going to build two-identical nine storey integrated classroom buildings. The buildings were designed to have green building certificate by proposing and fulfilling the requirements from the Green Building Council Indonesia (GBCI) rating system. For design recognition (DR) phase, the system requires efforts and measures in energy efficiency. The paper analyses all design aspects and criteria included in the working drawings, technical specifications, and bill of quantities as provided in the buildings detailed-engineering-design (DED). The analysis covers the calculation of overall thermal transfer value (OTTV), artificial lighting, vertical transportation, and air conditioning system. By using energy modelling software, the OTTV for Building A and Building B, with 19,445.13 m2 of total floor area using VRF-AC system, are 31.78 W/m2 and 33.48 W/m2 respectively. The proposed annual energy use is 3510.90 MWh with the index of energy consumption is 180.55 kWh/m2 per-year. The results showed that by achieving 32.58% of energy efficiency, the DR of UM’s two classroom buildings is affordable to attain 11 points in the rating system.
