LG Twin Tower, located in Yeoido, is the headquarter of LG Group that covers
14,733 m² of land and 157,835 m² of gross floor space. The two buildings have
3 underground levels and 34 ground levels with a seating capacity of over
10,000. Since the consturction in 1987, LG Twin Tower has required no repair
work. However, the equipment installed throughout the buildings had become
obsolete, while the maintenance costs and energy costs continued to grow.
As a landmark of Seoul, LG started to renovate the building in June 2010, in
order to enhance LG brand image and to improve the working conditions.
Three main purposes of this renovation project were to bring about greater eco-
friendliness for greater energy savings, to create a modern working environment
and to provide a comfortable working space with new equipment. To achieve
this, it required a significant improvement of the lighting system which accounts
for 30% of energy consumption in large buildings. To provide an optimal
environment, it must be environmentally friendly and compatible with the existing
facilities allowing integrated control system. These are the reasons behind the
selection of LG LED Lighting.

With fluorescent lights’ high energy consumption, there was always a big burden
on overall energy costs. Moreover, with the rising issue of energy cost regulation
for big buildings, we needed a new solution. Fluorescent lights are short-lived,
while they also require higher maintenance costs, as around 400 fluorescent
lights have to be changed daily. Due to replacement, labor and disposal costs,
the fluorescent light really was wasteful.” (Pan-Sik Choi, senior research engineer
of Serveone) The biggest problem before the renovation was the electricity cost
of conventional lighting and the maintenance costs of deteriorated equipment.
With two buildings each having 34 floors, the total number of fluorescent lights
was over 50,000. Hundreds of fluorescent lights with a maximum life span of
8,000 hours need to be changed every day. As the government’s regulation
is becoming stricter, more effective energy saving solutions were desperately
needed. Lighting with minimum power consumption was needed, as well as
eco-friendliness and integrated control optimized for a high technology working
environment.

The scale of the project was unprecedented, as it installed the country’s largest
working space with LED lighting and control. Therefore, we needed a brand
equipped with better quality and solutions that went beyond simple lighting
service. “Perhaps replacing just lighting is not that difficult. But, the management
system for controlling them was vital.” (Min-Kwang Lee, senior research engineer
of LGE) LG Electronics suggested the following three key factors for Twin Tower’s
renovation process.

EFFICIENCy : Effective energy saving technology
LG LED flat light, which replaced 80W conventional fluorescent lights, has a
power consumption of 53W while bringing 20-30 percent in energy savings.
In addition, with the daylight sensor and the dimming function, up to 80 percent
of energy savings are possible. Illumination reduced by 50 percent can fully light
up the working space, while the daylight sensor installed at each window can
recognize outdoor daylights automatically and transmit a signal to help maintain
optimal indoor illumination. Moreover, a lifespan of 50,000 hours can noticeably
reduce the maintenance costs.

ComForT : optimal light for users
Another benefit of LG LED flat light is low UGR with less than 19. UGR level below
19 is optimal for the working space, providing workers with proper lighting for
writing, reading and computer work. Conventional fluorescent lights have UGR
levels between 22-23, which can cause stress for office workers who spend
extensive time under the lights. Additionally, LG LED is eco-friendly and brings
long-term health benefits, as it does not emit mercury, lead, ultraviolet rays or
infrared rays.

rELIaBILITy : Credibility and high quality
LG Twin Tower project has not only 17,000 LG LED flat lights (53W) replacing
conventional fluorescent lights, but also 3,000 LED downlights (15W) and 2,000
LED PAR30 (12W) replacing conventional halogen lamps. Particularly, LED flat light
is connected together with integrated control systems, making them more credible.
“We tested the products on 7th and 33rd floors of the West Tower for two months.
During the installation, communication, electricity and cabling were few of the
many variables to be managed. So, we plan to have continuous testing and
monitoring after the construction for further improvement.” (Bong-Geun Jung,
senior research engineer of LGE) LG LED Lighting was recognized both internally
and externally. American certification company, underwriters Laboratories(uL),
designated LG Electronics r&D center as a uL-authorized testing lab in the green
energy sector (e.g. solar, LED lighting). This means LG LED lighting can secure
high levels of reliability.

“Having a total solution technology with
the general advantages of LED lighting is
only possible with LG. Long lifespan, energy
efficiency and control solution combine to save
energy costs by up to KrW 10 million.” (Pan-
Su choi, senior research engineer of Serveone)
The most remarkable achievement after the
LG LED lighting installation was energy savings.
Twin Tower’s power consumption in January
greatly declined, recording 1,900,896kWh,
reducing up to 310,000kWh compared
to January 2010, which was before the
renovation. Assuming the average monthly power consumption is 200kWh, Twin
Tower’s energy consumption is equivalent to 1,550 households each month.
Electricity cost was KrW 190 million, enabling savings of KrW 10 million,
compared to 2010.
“The best part of moving into the renovated building was the lighting. compared
to the complicated atmosphere with separated fluorescent lights and luminaires,
I like the refined design that combines the lighting and ceiling in one. It’s also not
that glary as before. Each floor has controllable touch panels, so I can turn them
on, when I’m working overtime. Besides, I feel much relieved that it contains no
pernicious ingredients.” (Sang-Woo Lim, LG International)
This project proved the reliability and high energy efficiency of LG LED lighting
products, as well as its ability to provide an optimal environment for the users.
In short, LG LED lighting is expected to be widely recognized.
