Integrating persuasive technology with energy delegates for energy conservation and carbon emission reduction in a university campus

This paper presents the results of energy conservation strategies implemented in the University residential halls to address energy consumption issues, using IPTED (Integration of Persuasive Technology and Energy Delegate) in the student residential halls. The results show that real time energy feedback from a visual interface, when combined with energy delegate can provide significant energy savings. Therefore, applying IPTED reveals a significant conservation and carbon emission reduction as a result from the intervention conducted in student hall of residents comprising of 16 halls with 112 students. Overall, the intervention revealed that, the use of real time feedback system reduced energy consumption significantly when compared to baseline readings. Interestingly, we found that the combination of real time feedback system with a human energy delegate in 8 halls resulted in higher reduction of 37% in energy consumptions when compared to the baseline amounting to savings of 1360.49 kWh, and 713.71 kg of CO2 in the experimental halls. On the contrary, the 8 non-experimental halls, which were exposed to the real time feedback and weekly email alert, resulted in only 3.5% reduction in energy consumption when compared to the baseline, amounting to savings of only 165.00 kWh, and 86.56 kg of CO2.
