 Kasetsart University renovated buildings into ‘Smart Building’ by using Building Automation System (BAS). The BAS will automatically control air conditioning, lighting, fire control, access control, security and elevator control system. There are currently 31 units of users in the building, totaling 855,640 square meters. (Figure 2.2-1-7)

            There are 5 kinds of renewable energy that Kasetsart University set a policy for consumption namely: bio diesel, clean biomass, solar power, wind power and combination heat and power (biogas). The usage of renewable energy is 118, 103 kilowatt in 2017. 

1. Setting of 9 kilowatts solar cell panels for electrical consumption in the University

Solar Cell Panels 9 Kilowatts.

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 develop consecutively to KUB-200 which has a capacity of 200 liters / time, with a capacity of 700 liters / day.

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.

7 tons of pig excrement are processed into 12,000 liters of liquid fertilizer for cultivation. It is used 1.5 liters per rai /crop for 8,000 rai of paddy field and 3.5 liters per 3,400 rai of cassava.

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. Usage of wind power

Renewable energy is our main policy, namely: solar energy wind turbine and bio-gas pump engine. A good example is that solar energy is the power source for water planting.

 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.

‘KU Big Cleaning & Planting Day’ is an annual event of the University. It has been organized for 22 years since 1995. For this year, administrator, staff and students joined this event on 2 September 2017 to clean up their offices and together planted trees for better environment of four campuses of the University. (Fig. 2.7-2)

3. Maintenance of air conditioner for reduction of greenhouse gas emission and energy saving 

There are steps of air conditioner checking as follows: air conditioner’s refrigerant checking, high and low pressure checking and keeps the pressures in the standard level, and measure for electrical power consumption of air conditioners by checking of electrical current of compressor. (Fig. 2.7-3)

Figure 2.7-3 Cleaning air conditioner to reduce energy consumption.

4. Using of R-123 or HCFC-123 refrigerant

The R-123 or HCFC-123 refrigerant is a kind of Hydrochlorofluorocarbon (HCFC). It is low ozone depletion potential (ODP). R-123 has 0.012 or 1.2% ODP of R-11(CFC-11). It means that R-123 has lowest rate of ODP out of all HCFC. (Fig. 2.7-4 and 2.7-5)
