[Asia Economy Reporter Lim Hye-seon] LG Uplus announced on the 19th that it saved 5.72 million kilowatt-hours (KWh) of electricity by installing LED lighting and replacing old air conditioners in its offices nationwide to reduce power consumption.

Previously, since 2018, LG Uplus replaced 34,718 lights with high-efficiency LED bulbs in 31 offices across the country, achieving an annual electricity saving effect of 2,585,102 KWh.

In addition, it saved 2,481,053 KWh annually by installing an ‘outdoor air cooling system’ that lowers indoor temperature using cold air outside the building (2,041,200 KWh), replacing old air conditioners with ‘high-efficiency air conditioners’ equipped with EC fans that reduce friction during rotation (178,053 KWh), and replacing pulleys in communication room air conditioners (262,800 KWh).

Furthermore, it saved an additional 656,484 KWh annually through heat pump boilers that absorb heat from outdoor units to raise water temperature, solar power generation facilities introduced at Yongsan and Magok offices, elevator regenerative braking devices, and insulation of communication room walls.

The amount of energy saved at LG Uplus’s offices nationwide translates to a reduction of 2,629.44 tons of greenhouse gas emissions. Considering that a 30-year-old pine tree absorbs 6.6 kg of carbon dioxide annually, this is equivalent to planting approximately 400,000 pine trees, reflecting a similar carbon emission reduction effect.
