[2.1] Energy efficient appliances usage 

(Figure 2.1-1)

Figure 2.1-1 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 2.1-1)
Table 2.1-1 Consumption of efficient energy saving equipment.

Remark:

1. 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)
2. Refrigerant used in central air conditioners must be environmentally friendly.
3. Effective fluorescent lamp are T5/ LED lamp.
4. 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.

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. (Figure. 2.1-5)
