Energy efficient appliances usage
Proactive policy of approach on Green University
Kasetsart University has a policy on improvement of overall electrical appliances in the university. More than 85 percent of the total electrical equipment in the campus were replaced such as LED light bulbs instead of fluorescent and used energy-saving labels number 5 electrical appliances. (Table 1)
Table 1 Consumption of efficient energy saving equipment.
Remark:
- Energy-saving labels number 5 air conditioner with efficiency rating (EER) of 11.6 or above, according to the Electricity Generating Authority of Thailand (EGAT)
- Refrigerant used in central air conditioners must be environmentally friendly.
- Effective fluorescent lamp are T5/ LED lamp.
- Effective street lights are LED light bulbs

The Faculty of Science has been supported the 3,983 LED Tubes (18 watt/size 120 cm.), from the Department of Alternative Energy Development and Efficiency under the Energy Conservation Project in the government sector, fiscal year 2017, which was distributed throughout the faculty of science, with good efficiency and energy saving.
The new Science Laboratory Building is under construction. There are changes to the LED light bulbs as well to save energy and follow the university policy.
2. Energy-saving labels number 5 air conditioner with Invertor system can save 20-30 % of electrical power.
Energy-saving labels number 5 air conditioner
Temperature, humidity and carbon dioxide measuring system
Air ventilation system to control carbon dioxide and increase Good air circulation / ventilation
3. Changing of LED street lights
Kasetsart University conducted a project on changing of LED street lights. It is brighter and saved 50 – 70 % of electrical consumption.
Renewable energy produce inside campus
There are 5 kinds of renewable energy which Kasetsart University set a policy for consumption namely: bio diesel, clean biomass, solar power, wind power and combination of heat and power (biogas). The usage of renewable energy is 128,503 kilowatt in 2018.0.17
1. Setting of 9 kilowatts solar cell panels for electrical consumption in the university
Solar Cell Panels 9 Kilowatts.
ON GRID system
Kasetsart University provided an electrical production from solar cell set for demonstration.
Solar Cell Panels 30 Kilowatts.
Using of solar power for water pump.
Solar energy recycle training station Solar energy fills oxygen in water
Kasetsart University is keeping update and improves the landscape along the Rapee Sakrik Building. The university choose to provide the pathways light with solar power for energy saving.
Solar cell lamps along the Rapee Sakrik Building.
On 28 March 2018, the 600 upgraded version of ‘Mobike’- smart bicycles were added for service. The bikes were recreated with stronger and wearable structure, adjustable seat, and chargeable solar cell electricity for GPS and unlock system.
2. Biodiesel production station
Sustainable development and sustainable growth
Kasetsart University produced biodiesel by BTC-150 machine. The BTC-150 has a capacity of 150 liters/ time and develops consecutively to KUB-200 which has a capacity of 200 liters / time, with a capacity of 700 liters / day.
BTC-150 KUB-200
A 12 hp. & 5-kw.- farm generator powered by integrated fuels of biogas, synthesized gas and diesel oil
A 100-kw.- farm generator powered by integrated fuels of synthesized gas from a 3-stage and diesel oil gasifier powered by fuel of paddy husk and diesel oil compressed bar charcoal on process of production
3. Biogas production station
Biogas production station of Kasetsart University produced gas from food waste 400 kg. /day and converted into heat energy from a gas tank of 15 cubic meters to use in the canteen.
Poultry manure is put into biogas production dome. The biogas is used for electricity generating system of poultry farm. It is also transformed to fertilizer pellet.
Swine manure is put into digester tunnel to produce biogas for in-farm cooking and herbal sauna.
Dairy cattle manure is put into digester tunnel to produce the biogas for in-farm cooking and pasteurized-milk production.
Cattle manure is put into covered digester pit to produce the biogas for farm electricity. It saves electricity cost of the farm.
4. Producing hot gas with a Gasification Stove
Gasification Stove has a diagram of Figure 1, which is heated to the neck at about 1200 ° C. This hot gas is heated to about 5,000 kilojoules (kJ)., which can be ignited. The composition of the biomass consists of Carbon Monoxide 18-25%, Carbon Dioxide 5-10%, Hydrogen 13-15%, Methane 3-5%, Nitrogen 45-54%, and Steam 10-15%. There is also a hot gas fired furnace with charcoal and biomass as shown in Fig. 1 and Fig 2.
5. Usage of wind power
1. The design of the building for ventilation and natural light.
Architectural Building, the Faculty of Architecture
Lecture Building of the Faculty of Business Administration (Building 4)
Library in the Park
The Office of the University Library created area between buildings as “Library in the Park” so that students can sit and relax in natural site.
To respond to the “Green Campus” policy, the Office of the University Library renovated 475 square metres of space (which was damaged from mega flood incident in 2011) within the office to be “Library in the Park”- reading area in natural atmosphere and saving energy for student and staff. Moreover, the Office separated space within the Library in the Park as a site of special event such as “Music in the Park” among variety of botanical garden which comprised of 2 species of plant: Acanthaceae and Bignoniaceae.
Vajiranusorn Building, Faculty of Agriculture
Agro-industry Research Operation Building: saving energy building ventilates fresh air inside without air-conditioner and uses transparent windows and walls to save electrical energy.
2. The Faculties/Offices of Kasetsart University appointed a sub-committee on energy management to set a policy and plan of energy conservation approach that follow the university’s overall plan and appointed managers of building who can conduct efficiently the plan. (Figure 2.9-2)
Kasetsart University Library/Learning Center (KULC) wins the Thailand Energy Awards 2018
Kasetsart University Library/Learning Center (KULC) wins the Thailand Energy Awards 2018 for concept of energy efficient building. Dr. Anamai Damnet, Vice President for Special Projects and Suphan Buri Establishment Campus Project, received the award plaque from Deputy Prime Minister of Thailand Air Chief Marshal Prajin Juntong, The library representative including Dr. Aree Thunkijjanukij and staff of library participated in the award ceremony.
Kasetsart University Library/Learning Center (KULC) has been promoting the energy conservation in the library building since 2015-2017, such as installation of paper pulp roof insulation, replacing LED lamps, installing pull-chain light fixtures, installing air exchanger & ventilator equipment. Overall it helps saving the energy up to 501,973 kWh.
In addition, the 7S Model for Organization Improvement and the transferring of technology and knowledge among 10 members of the Green Library Network have also been implemented. The Thailand Energy Awards 2018, the Department of Alternative Energy Development and Efficiency organized the contest to honor those who have outstanding performance in energy conservation and alternative energy development. It promotes awareness of energy conservation and promotes the development of alternative energy. It also creates awareness for those who are involved in applying for sustainable development.
