UM’s energy conversation measures produce good results

The University of Macau (UM) strives to build a green campus. The UM campus covers approximately one square kilometre with more than 60 buildings that serve teaching, research, and residential purposes. Therefore, energy conservation has been a major goal of the university’s environmental policies. Last year, between August and December, UM held its first Energy Saving Competition, and the outcome was very encouraging. The university’s electricity cost in 2016 was reduced by millions of patacas, down 7.8 per cent from 2015. The reduction of energy consumption mostly came from air-conditioners and lighting systems.

UM’s energy conversation programme is carried out by the Energy Section of the Campus Management and Development Office. The programme aims to optimise the energy performance of electromechanical facilities and enhance energy management. Staff of the Energy Section conduct site inspections and hear users’ feedback on a regular basis, in order to identify energy management opportunities (EMO) and find solutions for the users.

A comparison of UM’s electricity consumption data in 2015 and 2016 shows that air-conditioners are the most energy-consuming devices in most of the buildings on campus. Therefore, in the first stage of implementing the energy conservation programme, UM focused on optimising refrigeration systems and other air-conditioning control devices. UM also implemented conservation measures for lighting systems, including optimising the control of some lighting systems, removing unnecessary lights, and using energy-efficient lights. Additionally, UM held its first Energy Saving Competition from August to December last year, in an effort to raise environmental awareness among its staff and promote a culture of energy conservation on campus. 45 departments from 21 buildings participated in the competition. The departments were required to initiate their own energy conversation measures and encourage faculty and staff members to enforce them.

This year, UM will continue to organise the Energy Saving Competition. A major project in 2017 will be the integration and upgrade of its exiting power monitoring system into a centralised power monitoring and analysis system, which will be able to organise and share real-time data on electricity consumption of each building with all the departments on campus for their reference. The project is part of the university’s effort to build a smart campus, and it aims to realise intelligent data analysis and management for better energy efficiency. The university will also continue to identify energy management opportunities on campus and conduct feasibility studies on the implementation of other energy conservation programmes for sustainable development.
