7.2.4 Plan to reduce energy consumption
Energy efficiency plan to reduce overall energy consumption
Srinakharinwirot University (SWU) has an energy efficiency plan in place to reduce overall energy consumption. The Policy on Carbon Neutrality (Carbon Neutral – Scope 1) by 2050 and Achieving Net Zero Greenhouse Gas Emissions by 2065 (SWU Zero Carbon) and Waste Separation within the University (SWU Zero Waste) was announced on 13 December 2024 by the Acting President of Srinakharinwirot University (SWU) and applies across all university areas throughout 2025.
Energy reduction target and measures
The policy sets a measurable target to reduce energy consumption within the University by decreasing electricity (and tap water) use by 5% each year. To achieve this, it requires the replacement of lighting with LED bulbs and of air conditioners with energy-saving (Label No. 5) units in all university areas (item 1), the promotion of alternative energy such as solar cells and floating solar systems together with collaboration with external agencies on energy conservation (item 4), and the renovation and construction of buildings in accordance with energy-saving guidelines (item 5).

SWU also publicly describes its ongoing energy-saving measures across campuses, including automatic lighting control systems that schedule indoor and outdoor lighting, replacement of air-conditioning units with energy-saving models, solar cell systems on selected buildings, conversion of lighting to LED, and campaigns encouraging staff and students to switch off air conditioners and lights when not in use.

Monitoring energy consumption in 2025: Green Library and Green Office
As part of this plan, units monitor their electricity consumption to analyse trends, plan and improve energy conservation measures. The Central Library of SWU records and publishes the monthly electricity consumption of its buildings under its Green Library and Green Office approach, and encourages users and staff to save energy by switching off lights and air conditioners when not in use.
In 2025 (B.E. 2568), the Central Library building on the Prasarnmit Campus used a total of 812,000 kWh of electricity (an average of 67,666.67 kWh per month), and recorded 100,005 users over the year so that consumption per user could be tracked. The Ongkharak Library used a total of 672,511 kWh in 2025. These monthly records provide the baseline for measuring progress towards the University’s target of reducing electricity consumption by 5% each year.

University-wide electricity monitoring in 2025
Beyond individual units, SWU tracks the monthly electricity consumption of both of its campuses through the SWU SDG Sustainability Web App dashboard, which reports consumption in kWh and GJ by campus and by month. In 2025 (B.E. 2568), the University used a total of 55,710,830 kWh (200,559 GJ) of electricity: 27,112,842 kWh (97,606 GJ) at Ongkharak Campus and 28,597,988 kWh (102,953 GJ) at Prasarnmit Campus. At Ongkharak Campus, consumption fell from 29,344,049 kWh in 2024 to 27,112,842 kWh in 2025, a reduction of 7.6%, which exceeds the University’s target of reducing electricity use by 5% each year.

Energy-efficiency project in 2025
In 2025 (B.E. 2568), the Central Library procured construction work to upgrade the lighting control system inside its existing building to a smart lighting control system (e-GP project no. 68039090133). The invitation to bid was announced on 17 March 2025 with a reference price of 24,610,000 THB; two bidders submitted proposals and the contract award was announced on 27 May 2025. Upgrading the lighting control of this heavily used existing building directly supports the reduction of electricity consumption under the plan.

Through its measurable reduction target, monitoring of electricity consumption across both campuses, energy-efficiency measures and projects such as the 2025 smart lighting upgrade, SWU implements a plan to reduce overall energy consumption, and the evidence is publicly available.
