SI 2 Safe Buildings and Safe, Clean, Green Environments

[2.4] Advanced Energy Management Systems

Description:

Energy management at Siam University is guided by the Green and Clean Campus Policy and the “Siam University Carbon Neutrality 2045” policy, approved by the University Council on 31 August 2022 and revised on 30 October 2024. The policy calls for carbon-reduction innovation, a carbon-footprint measurement unit, clean and alternative energy, the 3R campaign, tree planting, public transport and electric vehicles, and awareness among staff and students. The Center for Sustainability, set up in 2018, coordinates these programmes, and building energy managers are assigned to each building. All five energy management strategies listed by HURS are in place (Table SI 2.4.1).

Monitoring and measurable savings. The University publishes an energy management report every calendar year with monthly electricity data. Consumption fell from 4,823,154 kWh to 3,989,158 kWh and 3,381,856 kWh in the years shown in the report (Figure and Table SI 2.4.3), helped by solar power, energy-saving appliances, control of electricity in lecture rooms and lifts, replacement of air conditioners and solar lights along walkways. The solar plant is monitored online; by October 2024 it had produced 773.15 MWh and avoided 463.89 tonnes of CO₂.

Alternative energy. Solar rooftops (526.21 kWp, connected to the grid on 9 March 2023) produced 985,698 kWh and the wind turbines 4,622.4 kWh, a total of 990,320.4 kWh – 30.14% of the electricity purchased (Table SI 2.4.2).

Infrastructure performance. Building energy managers check the buildings routinely, and the Golden Jubilee Building has been an MEA energy-saving building since 2015, with natural ventilation, daylighting and an energy-saving controller. All eight buildings were assessed against smart-building criteria (automation, safety, energy, water, indoor environment and lighting); buildings with at least five criteria cover 67,356.18 m² of 89,373.58 m², or 75.36% of the floor area. The 19-storey building and its equipment are inspected every year by a licensed building inspector.

Greenhouse gas reduction and behaviour change. The greenhouse gas reduction programme covers Scope 1 (free electric vehicles and bicycles on campus), Scope 2 (solar and wind power) and Scope 3 (public transport, carpooling and walking). Campaigns include the Carbon Neutrality 2045 and 3R campaigns, the Ecolife no-single-use-plastic campaign and “Say No to Plastic, Say Yes to Cloth Bag”. At SUN@Siam University (30–31 August 2024), 32 higher education institutions joined an “Energy Talk” on sustainable energy. The University also runs EV design programmes, student EV prototypes and an EV charging station. Its Energy & Climate Change score in the UI GreenMetric rankings rose from 1,300 in 2021 to 1,850 in 2025 and 1,775 in 2026 (Table SI 2.4.4).

Selected level: Comprehensive Implementation (5 items or more) – 10 of 10 points.
