Since February 2016, a pilot project was initiated by the Estate Office UBD in collaboration with the Department of Mechanical and Electrical, Public Work Department to reduce energy consumption from UBD’s 10 academic buildings including Administration building that conserve $170,000.00 per year.
According to World Bank, 2013, Brunei’s energy consumption of 2.5 ton of oil per capita and electricity per capita consumption of 8,5061kwh has one of the highest energy consumption per capita in the world and UBD is one of the highest energy consumer with its building’s auxiliary electricity bills of $300,000.00/month.
Energy savings on chiller plant can be achieved by implementing no and low cost operational adjustment to improve operational efficiency, carried out maintenance practices and changes of occupant’s behavior.
Estate Office under guidance of the Assistant Vice Chancellor (Corporate and Administration) has conducted a pilot project since February 2016. All Air Handling Units (AHU) in selected 10 buildings were switched off every 5pm and resumed operations at 6am the next morning for weekdays and total switch off for Fridays and Sundays. This does not include Library and certain rooms that require constant cool temperature. In addition to the pilot project, AHU’s temperature has been set to 23°C.
As a result, UBD managed to reduce 24% of the energy usage, which $14,000.00 per month with a total of $170,000.00 per year by merely diminishing air-conditioning usage only. Lessening the usage of lights and other electrical appliances and equipment can attain further reduction.
Converting conventional to sustainable building by implementing energy saving fittings and renewable technologies will be one of Estate Office’ subsequent projects.
