Abstract:
This thesis aimed at studying of electrical energy consumption and finding out energy utilization indices at the Sirinthorn Building, Khon Khaen Hospital. The results would
be proposed to be methods for electrical energy saves. Data collecting began by collecting data from documents such as building diagrams, electrical system blueprints,
construction blueprints and electrical energy bills. Some data such as electrical equipment installation were obtained by surveys. Then, data were collected using electrical
measuring instrument to measure the total electrical energy of the building and the electrical energy of air-conditioner system to find out the energy utilization indices of
building and other systems including to evaluate the electrical energy saves.
From the results, it revealed that the Sirinthorn Building at Khon Khaen hospital had general similar appearance that was a squared building made of concrete as its main materials.
In the building, there were lighting and air-conditioned systems. Most of electrical energy loss were resulted from a lack short of maintenance in electrical equipment and too
much electrical lamps installation. Brightness in some areas were too high from a specified standard. Using of electrical equipment was inefficient. In addition, working time
of electrical equipment was too long. Then, this research suggested the following strategies.
Firstly, unnecessary lamps should be removed. This could save the electrical energy about 96,540.8 kWh/year and 178,600.48 baht. Secondly, the electrical energy save should be
done by cleaning and having maintenance on the electrical equipment such as cleaning air conditions. This could save the electrical energy about 38,525.10 kWh/year and 71,271.4
4 baht. Thirdly, the electrical energy save should be done by installing energy save equipment such as electronic ballast. This could save the electrical energy about 88,280.3 k
Wh/year and 163,318.5 baht. Fourthly, a normal thermostat should be replaced by an electronic thermostat. This could save the electrical energy about 35,345 kWh/year and
8,500.45 baht. Finally, the electrical energy save strategy should be used by using time switch to control the air-conditions. This could save the electrical energy about 9,768.35
kWh/year and 18,071.45 baht.
