| Summary: | This research focuses on studying energy auditing potential
in university buildings following the ISO 50001 Energy
Management standard. The sample area is the Faculty of
Animal Science and Technology Building, Maejo University.
The area's scope is a lecture building (building A) and
conference building (building B). For energy indicators
analysis is divided into three levels: organization level,
system level, and equipment level. The results found that the
sample building used 100% electricity or about 166,041.66
kWh/year. The significant energy use (SEU) area was the air
conditioning system that consumed the highest energy use
approximately 38.33%, following by the lighting system,
other systems, lift system, ventilation system and pump
system which their proportion are 30.76%, 28.32%, 1.43%,
0.95%, and 0.21, respectively. The energy utilization index
(EUI) before the study is equal to 5.49 kWh/m2∙year higher
than after the study assessment that is equal to 3.75
kWh/m2∙year from four recommended measures for
example; lighting bulb reducing in the brighter area than
standard, changing the fluorescent bulb to LED bulb,
changing air conditioning to use a high-efficiency air
conditioner, and reducing time ventilation fans in the airconditioned room. If the sample building will improve
following recommended measures, the expected result is a
great saving than the current situation. The energy
performance index (EPI) of will be decreased by about
31.63%. The electricity will be saved of 32,239.38 kWh/year
or equivalent to 125,088.78 Baht/year which the investment
cost is about 682,075.00 Baht and get a payback period of
5.45 years. |
