Chiang Mai University undertakes energy reviews to identify the areas of highest energy waste across its campus, in support of SDG 7 (Affordable and Clean Energy). As energy efficiency and carbon reduction become priorities for large institutions worldwide, knowing which faculties, units and buildings use the most energy is the first step to reducing waste. The University does this through two complementary energy monitoring systems: the CMU Smart City Clean Energy Monitor, a publicly accessible website where anyone can view the data, and the Meter Report of the Sustainable Campus Management Center (SCMC), which reports electricity use of each faculty and unit month by month. The sections below describe how these systems are used to review electricity consumption and identify where energy waste is highest.
Energy Monitoring Dashboard: Reviewing Electricity Use to Identify Areas of Highest Energy Waste
The CMU Smart City Clean Energy dashboard, operated with the Energy Research and Development Institute (ERDI-CMU), gives a campus-wide energy review of electricity consumption and peak power demand. It also reports renewable energy generation, separated into on-peak and off-peak periods. This lets the university see how much electricity is consumed and how much is supplied from clean sources. The dashboard ranks every faculty and unit by its current power demand (kW), showing which units draw the most electricity at any moment and so where energy wastage is most likely to occur. To make comparisons fair across units of different sizes, it also uses energy intensity indicators: kWh per person for faculties and kWh per air-conditioned area for service units and buildings. These are shown as monthly charts, so units with unusually high energy use can be identified and changes over time can be followed. Together, these views form the core of the energy wastage identification process, because they show where attention is needed first.
Meter Report from the Sustainable Campus Management Center (SCMC)
Alongside the energy monitoring dashboard, Chiang Mai University provides a Meter Report system on the website of the Sustainable Campus Management Center (SCMC). The system reports electricity and water consumption of faculties and units, giving them a consistent, unit-level record for monitoring resource use and identifying where energy waste is highest. This section describes what the Meter Report presents and how it supports the review.
Monthly Electricity Consumption Overview of All Units
The Meter Report presents a monthly overview of electricity consumption across all faculties and units. Each month is shown as a stacked bar combining electricity from the Provincial Electricity Authority (PEA) grid and from solar PV, in kilowatt-hours (kWh), so that the share supplied by renewable energy can be seen alongside grid electricity. The chart places two consecutive years side by side (B.E. 2568 and 2569) and shows the date of the latest data. A second chart reports the monthly increase and decrease in electricity use compared with the same month of the previous year. It adds up the units that used more electricity and the units that used less, so that changes over time can be followed at the level of the whole university and the units driving them can be investigated further.
Monthly Electricity Consumption by Faculty and Unit
For each faculty or unit, the Meter Report provides a dedicated monthly report that can be opened from the unit list. The page is organised in tabs for electricity consumption (kWh) and electricity budget (baht), each separated into PEA grid electricity and solar PV. A bar chart compares each month of two consecutive years, and a monthly table below it lists kWh and baht for PEA and PV together with the total cost. A link to historical electricity reports is also provided. This unit-level view allows each faculty or unit to monitor its own electricity use, compare it with the previous year and identify months of unusually high consumption.
In summary, Chiang Mai University undertakes energy reviews to identify the areas of highest energy waste through energy monitoring and energy analytics systems. The CMU Smart City Clean Energy Monitor combines power demand ranking and energy intensity benchmarking across faculties and units, while the Meter Report of the Sustainable Campus Management Center (SCMC) provides monthly electricity records for the whole university and for each unit, with year-on-year comparison. Together they help the University follow changes in electricity use, look further into units with unusually high consumption, and support energy efficiency, energy conservation and Sustainable Development Goal 7 (Affordable and Clean Energy).
