100% LED Replacement (2.2 Million Lamps) for the Public Sector by 2018 - Seoul Metropolitan Government
  • Start year: 2014
  • Type: Technical/Infrastructure investment
  • Status: In operation

SMG plans to replace all the lights (2.2 million) in the city’s public sector
including public buildings, subway stations, and security lamps with LED lamps
by 2018. In 2014, it will complete the replacement in subway stations plus
350,000 lamps in district offices and municipal hospitals, for a total of 1
million lamps. From 2015 to 2016, it will replace 500,000 lamps including
those in the city’s welfare facilities and affiliated offices (100%) and security
lights and street lamps (50%). Between 2017 and 2018, it will replace a total of
700,000 lamps including those in its various corporations and the other 50% of
its security lights and street lamps. Meanwhile, SMG will enhance the "Design
Criteria for Public Facilities" to ensure the installation of LED lights in new
public buildings. For old public buildings, it will set up an exclusive
organization called SPC consisting of representatives of the central government
(Korea Finance Corporation, etc.), SMG (road management departments), and
private R&D institutions in 2015 in an attempt to minimize the financial
burdens associated with LED replacement and promote the faster implementation
of the replacement work.

LED Replacement in the Private Sector: 25% → 65% - Seoul Metropolitan Government
  • Start year: 2014
  • Type: Technical/Infrastructure investment
  • Status: In operation

private sector – with LED lamps by 2018. To this end, it will enhance the
LED design criteria in the "Green Building Design Guidelines” for new
structures measuring more than 500 square meters. By the end of 2014, all the
buildings in the city will have to replace more than 25% of their lights with
LED lamps and 100% of their lights in underground garages with LED lighting
fixtures. By 2020, all the lights in buildings will have to be LED lamps. SMG
will support LED light installation in numerous apartment garages throughout the
city by having the "Ordinance for Multi-unit Dwelling Support” of the city’s 25
self-governing districts revised. Through the modification of the “Seoul Special
City Ordinance on Outdoor Advertisements,” SMG will make it compulsory for
businesses to change signboard lights into energy-efficient LED lamps. Even
before the ordinance is modified, it will have 2,000 signboards changed to
LED-based ones each year through agreement with shopkeepers. In addition,
through the meetings of the Light Pollution Prevention Council, it will
encourage the installation of high-efficiency lighting fixtures while discouraging
the excessive use of lights.
SMG will expand the voluntary LED distribution in the private sector through
collaboration with the private sector and PR campaigns. It plans to launch the
"On-Site LED Direct Marketplace" in apartment complexes 200 times. In
cooperation with the city’s Buddhist leaders, it will distribute 1 million LED
lotus lanterns to 500 Buddhist temples. SMG will also open an online
information plaza to provide citizens with information on LED prices and
technologies. In addition, it will set up 20 PR booths at the Gwanghwamun and
Idae Stations to provide diverse information on LED to citizens. It plans to
establish “LED Hub Centers” as the city’s regional network for LED
distribution.SMG plans to install one or two LED hub centers in each of the city’s six
areas in cooperation with civil society. The centers will provide one-stop service
for counseling, PR, price information, and joint purchase. It will also join forces
with the Korea Franchise Association and large-scale discount stores to distribute
LED lamps. On behalf of its 100 member companies, the association will sign a
contract to install LED lights in their new stores. Discount stores will observe
the "LED Purchase Day" regularly and display LED publicity materials in their
SMG will also join hands with corporations to develop LED technologies and
expand the LED market through marketing support. To this end, it will run an
LED test site in collaboration with the Korea Photonics Technology Institute and
SMEs to promote the quality reliability of SME products. Most notably, SMG
will perform the evaluation of effects of emotional lighting and hospital lighting
with the Korea Institute of Lighting Technology and Korea Photonics
Technology Institute in an effort to help improve the performance of LED smart
To spur the development of LED technologies, SMG will issue the “LED
Distribution Standards for Public Institutions in Seoul," which will allow LED
lights to be evaluated in terms of optical functions and require LED efficiency
to be 10% higher than the national specification. In addition, it will launch the
Seoul LED Lighting Fair every year to expand the LED market and open the
Comprehensive LED Information Center in Konkuk University for the display
and selling of LED lighting fixtures as well as information service and technical

LED Expansion and Development - Seoul Metropolitan Government
  • Start year: 2012
  • Type: Technical/Infrastructure investment
  • Status: In operation

Seoul aims to be a Mecca of LED technology and commercialization.
By the end of the current year, the city plans to
install 64,000 LED lights in public buildings and subway stations,
leading to a 7060 TOE’s worth of electricity by 2014.
The city government is also encouraging multi-use facilities
like supermarkets and department stores to replace their
lighting sources with LED, and simultaneously works to replace
signs and street lamps with LED illumination.

GHG emissions reduce by 0.2t/y Energy consumption per citizen with Seoul Public Transportation - Seoul Metropolitan Government
  • Start year: 2010
  • Type: Technical/Infrastructure investment
  • Status: In operation

The combined effect of GHG reductions and energy conservation is equivalent to planting 86 pine trees in 2020 and 146 pine trees in 2030. (Such positive impact is the result of changes in the transportation mode share, improved fuel-efficiency, and introduction of eco-friendly vehicles.)

Optimized BRP through Precise Diagnosis of Energy Usage - Seoul Metropolitan Government
  • Start year: 2014
  • Type: Technical/Infrastructure investment
  • Status: In operation

SMG will improve regulations so that big buildings consuming more than 2,000
TOE will have to go through rigorous energy diagnosis procedures. Specifically,
it will persuade the central government to delegate the authority of the Minister
of Trade, Industry, and Energy to issue orders for building energy diagnosis to
the heads of local governments including the mayor of Seoul. The amended law
will also allow the heads of local governments to issue improvement orders
when buildings fail to make more than 5% improvement in their energy
efficiency. Meanwhile, SMG will develop and disseminate different energy
conservation models for groups of buildings such as hospitals, schools,
businesses, and hotels by the end of 2014. SMG offers tailored energy diagnosis
for houses and buildings. Current energy usage will be carefully reviewed, and
energy saving measures will be recommended free of charge by different groups
of experts: houses, by energy consultants; shops in small ~ medium-sized
buildings, by energy designers, and; welfare facilities and educational institutions,
by professional energy diagnosis companies. SMG will carry out BRP for the
city’s basic urban infrastructure, too. It will focus on improving the efficiency
of electrical facilities in sewage treatment facilities through the replacement of
old motors with high-efficiency ones and convert into heat source the digestion
gas generated in the sewage treatment process. It will also introduce intelligent
electricity load management systems in water purification centers. In addition,
SMG will begin operating subway cars that enable the recovery of the
electricity generated during brake applications.
