Abstract

The purpose of this study is to explain the design of the energy management system of Universitas Darma Persada (Unsada), in order to become a green campus through the energy audit and energy efficiency program. The program utilizes the campus as an energy saving laboratory that is able to identify, recommend, implement and evaluate energy consumption, so that the expected energy efficiency targets are achieved. This program is expected to contribute to scientific publications in an effort to elevate the ranking of Unsada at the university level throughout Indonesia. This program is motivated by several reasons, such as; to support government policies in reducing dependence on fossil energy by implementing energy conservation programs; as a reflection of compliance with the implementation of educational service buildings (including the campus in Jakarta); the vision of the green campus that has been determined by the campus management must be realized immediately by making the energy savings and renewable energy applications. To achieve these goals, there are five stages. First is the preparation stage, consisting of lecturing (audit energy system, certification, saving calculation, etc.), briefing/preparation (instrumentation, campus layout, energy bill, campus tour, area scope, group, role, task, schedule, etc.), auditing (cooling, lighting, behaviour, current classroom management, etc.), final presentation (finding of losses and opportunities, recommendations how to save, base measurement). Second is the conducting audit stage, which consists of a walk-through audit, data collection on monthly energy consumption, monthly energy bills, layout of each building, etc. Third is the audit analysis stage, consisting of analysing all audit findings, analysing consumption data and the layout of each building. Fourth is the recommendation for implementation stage, consisting of getting commitment from campus management, signed commitment from the management, implementation/action (TRNSYS building simulation, cooling load reduction, start-up/shut-down procedure, improved classroom management, energy awareness training and campaign, meter reading), evaluation (data collection, base to actual energy consumption, weekly energy report to management, energy system and behaviour audit). The results of the audit stages provide an overview of the opportunities and preparation that must be done in order to achieve the expected energy savings. As a conclusion, to save energy on campus, it is necessary to have a clear energy vision with strong designs of energy management system by involving all stack-holders on campus, ranging from students, employees, lecturers, to campus management.
