Energy and Climate Change

Implementation of energy efficient policies and energy conservation programs

In 2018, SWU Ongkharak Campus has replaced 30,000 of their 34,000 36-watt halogen lightbulbs with 18-watt LED bulbs. Additionally, there are recently completed campaigns of replacing their aircon units with brand new energy efficient units (some inverters and some VRFs) throughout the campus.

Renewable Energy

There are three renewable energy sources—Solar, Biomass power plant and Bio-methane and Pyrolysis oil—being in used in Ongkharak campus, with solar powered lighting in several carparks and in newly-installed pedestrian walkways. Pyrolysis oil can be used as fuels for gardening equipment and heating.

Pyrolysis process

Pyrolysis is the thermal decomposition of materials at elevated temperatures in an inert atmosphere. It involves a change of chemical composition and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating".

Elements of green building

Natural day-lighting and natural ventilation is commonly implemented in many of SWU Ongkharak’s faculty buildings. Tinted windows are used in all new building construction and in renovated buildings. Facades are installed in the southward and westward sides of the buildings to protect heat from the afternoon sunlight. Additionally, each building has a dedicated Manager to ensure minimum energy usage occurs.
