Energy Saving
of Data Center
SET is keen on optimizing the efficiency of the computer center to support business. Tomeet this goal,
the resource management was put in place to address energy cost efficiency andminimize the impact
to the environment. The aim is to reduce energy usage, non-renewable resource consumption
and greenhouse glass emissions. Implementation included air-conditioning system management,
wind direction management, internal environment management and maintenance.

Air-conditioning system and wind direction management
Internal environment management
Tropical climate in Thailand triggers a large amount
of energy consumption for cooling purpose.
To enhance the operation at the computer center
while having less effect to the environment, SET
installed an air-conditioning system with efficient
humidity and temperature control. The location of
server rack cabinet was appropriately aligned with
the perforated raised floor. Cold aisle containment
system was integrated to maintain proper airflow
for the data center equipment. This method could
help eliminate a chance of sudden crash. As a result,
the air-conditioning system could work efficiently.
In 2014, the Power Usage Effectiveness (PUE)
showed a 15% improvement, compared with the
previous year.
The optimized temperature and humidity control of cooling system installed has enhanced the efficiency
of servers and equipment. It is significant that the environmentally friendly fire extinguishers installed
neither destroy the ozone layer nor cause damage to computer equipment. In addition, the automatic
lighting control was also installed across the areas.

Maintenance
The maintenance of electronic devices has been conducted on quarterly basis, including cleaning
the air-conditioner filter and cooling system, which could consequently help save energy and extend
the useful life. SET has replaced existing monitors and bulbs in the computer center with the LED ones
with relatively less energy consumption.
