Phase 1 of the project concentrated on creating a masterplanning (iCD) model of the EcoCampus, complete with energy signatures for each building on the campus.

The model was accurate to 91% for total energy consumption and 97% for chiller energy consumption. A corresponding online cloud based Community Information Model (iCIM) for communication and engagement with campus staff and students was also created and connected to the masterplanning model for automatic updates.

Using real operational data from utilities and NTU’s Building Management Systems (BMS), IES were able to assess and identify opportunities to achieve optimal performance in existing operational buildings across the campus, using its innovative Ci2 (Collect, Investigate, Compare, Invest) process.

During the ‘Collect’ and ‘Investigate’ stage, building information was gathered and operational data imported into iSCAN to investigate issues/faults across a selection of 21 buildings on the NTU campus. This brought to attention issues including: low and high CO2 levels, unstable off-coil temperatures, lower than expected return air temperatures, faulty energy consumption meters, and staff offices and meeting rooms temperature setting issues.
