In comparison with the fuel usage by airport-owned vehicles for business operation, electricity makes up more than 90% of energy consumption. Therefore, our efforts are directed towards effectively monitoring, analysing and optimising electricity usage. The total electricity consumed by our airports has seen a slight decrease in 2017 despite increased passenger movements. This indicates the success of the initiatives towards efficient energy. In fact, electricity usage per passenger has decreased by 10.4% from 2016 to 2017, which is 2.5 times the reduction from 2015 to 2016. ENERGY SAVING INITIATIVES Managing energy consumption and greenhouse gas (GHG) emissions is critical in the current economic and regulatory environment. Before the implementation of effective solutions to improve energy performance, Malaysia Airports’ energy consumption was systematically labelled and monitored both internally and externally. In compliance with Efficient Management of Electrical Energy Regulation (EMEER) 2008, Malaysia Airports implemented the Energy Management Information System (EMIS) initiated by the Energy Commission (EC). Through EMIS, energy performance data can be efficiently reviewed, verified and managed by the appointed Energy Manager (EM). Data submission to the EC is also accelerated as EMIS uses an online system 6 70 VOL VOL 75 55 JULY-SEPTEMBER JUNE 2013 2018 which allows users to submit energy performance data online. As a result, manual submission by the EM is no longer needed. In managing energy efficiently, internal monitoring is an effective approach. An e-Energy Dashboard was introduced by Malaysia Airports as a tool to monitor abnormalities in energy consumption trends of airport operations and database activities. This system also includes the Operation Information System (OIS) which serves relevant needs such as graft analysis, meter status and tariff detail. Data collected is used for identifying trends in performance analysis, reporting for all airports, and top management reviews. The e-Energy Dashboard also contains details such as electricity bills, maximum demand performance, monthly energy profiles and communication between airport and management. These reports facilitate energy performance or profile analysis. If an abnormality is detected, the technical team at airports can then responded immediately to rectify it. Information for justifications on energy savings projects and proposals can be extracted from this system. The next enhancements to be added are the live interface of performance indicators versus actual data for all airports to monitor their own energy profiles. To ensure efficient implementation of energy management, the Airport Energy Management Committee (AEMC) was established with the objective to introduce the Airpor t Energy Efficiency Programme Initiative (AEEPI) at the airport level. This programme will assist in the reporting and analysis of energy consumption using data ex tracted from the e -Energ y
