Cenergi Design Challenge

Energy Efficiency

Design Challenge 1: Building Energy Efficiency

In Malaysia, electricity demand is forecasted to reach 18,947 MW in 2020 and 23,092 MW in 2030. This is an increase of 22% in the next 10 years. Buildings are major consumers of electricity, accounting for almost one-third of energy consumption globally. The growth in energy consumption experienced is brought about both by an increase in new building constructions (about 6 % per year), inefficient energy utilization, and continuously increasing stock of electrical appliances in new and existing buildings. Thus, there exists a very large untapped potential for improving the energy performance of buildings in Malaysia.

The Design Challenge is to design an intelligent building energy management system to improve the energy utilization efficiency in buildings, using university buildings as test case. Energy consuming appliances to consider include air conditioners, ventilators, lightings, equipment, etc.

Among the areas to be considered in the design include:

  • Pattern/schedule of energy utilization: with known utilization hours (through historical patterns of behavior or through a time table), air conditioners that may be turned on/off or have its temperature adjusted according to the usage needs.
  • Turn on/sleep/off ventilators, lightings, and other equipment according to the presence of people.
  • Adjustable ventilation, lighting, air-conditioning, etc. according to the weather condition.
  • Tracking of energy consumption and energy savings achieved to measure ROI.

Design Challenge 2: Carbon Footprint Tracker

Cenergi prides itself on investing in projects that promote carbon reduction. At the end of every month, Cenergi circulates a report on how many CO2 equivalent tonnes of methane its four biogas plants prevent from being released into the atmosphere. Cenergi strives for a more precise indication of its total carbon impact to be available. In order to do this, part of the data needed is the carbon footprint of its staffs and business operations.

The Design Challenge involves designing a mobile/web app that can track carbon footprint of all individual staffs and business operations, then to feed the total information into Cenergi's carbon monitoring website. The carbon footprint tracking system would include:

  • The carbon footprint of staffs’ daily commuting back and forth between home and workplace, business travels, etc. Note that different modes of transport (bus, car, train, plane, etc.) will have different carbon footprint indications. The tracking of individual staff members should be made seamless and intuitive. Reporting and provision of information, from the point of view of staffs, should be convenient, practical, and intuitive.
  • Energy consumption of Cenergi’s different sites, including HQ (electricity bill data will be provided).
  • Cenergi’s biogas renewable energy plants’ electricity generation data (plants’ data will be provided) and its carbon reducing impact.
  • Other business operations that have a carbon footprint indication (eg. item shipment).


Impacts & Benefits of Taking Up the Challenge

  • Teams will be assigned mentor from Cenergi to provide expertise and advices needed.
  • Team members will have prioritized access to job opportunities offered by Cenergi.
  • Collaboration opportunity with Cenergi if the solution created is promising for further commercial or industrial development.

Cenergi is a team of diverse personalities with a common passion for promoting sustainable practices and reducing carbon emissions across Southeast Asia. We believe that conscious use of energy is key to a sustainable future. Together, we envision a world where society functions in harmony with the environment.

Our award-winning business is divided into three main areas; ‘Renewable Energy’, ‘Energy Efficiency’ and ‘New Ventures’. Across these areas, we possess the full spectrum of technical, commercial, financing and operational capabilities for clean energy and energy efficiency projects. We started our journey in 2010, and today Cenergi is the largest grid-connected Palm Oil Mill Effluent (POME) biogas players in Malaysia. We own and operate four plants that together generate 5.5 MW of power, with another 1.5 MW biogas plant to be commissioned later in 2018. We have also recently completed the second phase of a RM 40 million energy efficiency project that guarantees electricity savings of up to 33% for a local university.

By 2021, Cenergi aims to have 100 MW of operating clean energy assets and a total investment of RM 300 million in Energy Savings Performance Agreements (ESPA) projects.
