1 To Make Buildings in Seoul Greener Resilient Cities Session A5

2 Urbanization and Economic Growth in Seoul Population Housing Vehicles (Unit : 10K) 1, (Unit : 10K) 360 (Unit : 10K) (1960) (1980) (1990) (2010) (1960) (1980) (2000) (2010) (1960) (1980) (1990) (2010) Area Expansion Rapid urbanization & economic growth Resulted in environmental problems air & water pollution, waste, etc

3 Seoul s Environmental Policy Directions Vision Strategy Public-Private-Industrial Cooperative Governance for Environment and Climate Focus One Less Nuclear Power Plant World No. 1 Recycling City Healthy & Pleasant Neighbor -hood Green Jobs & Green Industry

4 One Less Nuclear Power Plant Vision Groundwork for energy self-sufficiency with an aim to become the world s climate & environment capital % % % - Raising power self-sufficiency to 8% by 2014, 20% by 2020 One less nuclear power plant = saving 2 million TOE by 2014 Goal Power 790,000 TOE (9,142 GWh) Petroleum and city gas 1.21 million TOE

5 Establish and operate an energy foundation Make Seoul a city of sunlight where the entire city is a PV plant (320 MW) Create citizen lifestyle with energy-saving actions Ensure energy selfsufficiency of core facilities by fuel cells (230 MW) Create 40,000 green jobs in energy sector 08 One Less Nuclear Power Plant 10 Key Action Plans 03 Improve energy efficiency of buildings (houses, commercial buildings, schools, etc.) Secure 150,000 memberships for car-sharing scheme Realize a Smart Lighting City by LED (dissemination of 8 million LED units) Reinforce design standards for 06 new buildings by introducing energy cap and other measures 05 Launch 2030 City Master Plan with a view to energy-efficient urban structure

6 There are 650,000 buildings in Seoul. Building Data (2012) Category Total House Apartment Commercial Building Number 656k (100%) 378k (57%) 115k (18%) 163k (25%) Commercial Buildings 163k (25%) Apartments 115k (18%) Houses 378k (57%)

7 Buildings account for 56% of energy consumption in Seoul. Industry 1,197k (7.7%) Transportation 4,631k (29.9%) Public sector 1,004k (6.5%) By economic sector (unit: TOE) Residential & commercial 8,664k (55.9%) Citywide 15,496 thousand TOE 7.5% of nationwide energy consumption Nationwide 205,863 thousand TOE Heat, New & Renewables Coal 716k 118k (4.6%) (0.8%) Electricity 4,034k (26.0%) By sources (unit: TOE) LNG gas 4,602k (29.7%) Petroleum 6,027k (38.9%) Residential and commercial buildings (55.9%) and vehicles (29.9%) account for 85.8% of the entire energy consumption. Seoul relies 95% of its energy on petroleum (39%), LNG gas (30%) and electricity (26%).

8 Making Buildings Greener: Efficiency improvement for both new & existing buildings Urban redesign into a low-energy compact city 2030 City Master Plan In reflection of compact city concept (e.g. intensive land use in subway station sphere) Stricter design standards e.g. energy consumption cap Mandatory requirement of over Good -grade 석유 green certification, 2 nd -grade energy 6,027 efficiency certification (38.9%) Retrofit existing buildings 도시가스 4,602 (29.7%) Building retrofit program for all buildings incl. houses and commercial buildings (Project loan up to 1.9 million USD at 2.0%/yr)

9 Magok Area Development Project: Low-Energy-Consumption Compact City Size: 3,363,591 m2 Main Development Features Over 40% of energy demand from new and renewable sources 1 st grade energy efficiency mandatory for all buildings 100% of lightings with semi-permanent, highly-efficient LEDs Water cycle to reduce heat island effect CPDP (Climate Positive Development Program) Eco-friendly city to minimize GHG emissions Effect: +5%/yr energy conservation; +65%/yr GHG emission cut Magok model to be reproduced everywhere in Seoul Applied to urban development projects to make Seoul a low-energy city

10 Reinforcement of Building Design Standards Reinforced energy consumption cap for large-sized buildings - Target: apartments and office buildings over 10,000 m 2 ; commercial spaces, accommodation sites & medical facilities (Unit : kwh/ m2 yr) Reinforced designing standards on mid-to-small-sized buildings to reduce energy consumption - Target: apartments below 10,000 m 2 ; research centers & commercial spaces over 3,000 m 2 ; hospitals, accommodation facilities over 2,000 m 2 * Good grade in green building certificate & 2nd energy efficiency grade mandatory * Mandatory submission of energy saving plan * Prohibition of glass wall covering over 50% of the building Continued supports for eco-friendly & low- energyconsuming buildings Apartment houses General buildings Public buildings - Reduction of acquisition tax and property tax by over 15% maximum - Exemption of 20~50% of the environmental improvement charges Starting 2013, the attachment of energy assessment documents in real estate contracts becomes mandatory.

11 Exemplary Green Building: New Seoul City Hall 24.5% of energy from renewable sources, top green building grade Use rainwater, heavy water & geothermal heat for heating & cooling (1,160RT) Photovoltaic power generation (BIPV, 200kW), solar thermal facility(131kw) Install eco-friendly green walls and curtain walls Solar energy Use only eco-friendly, high efficient LEDs New Seoul City Hall Natural ventilation Breathing Curtain Wall Open 38% of City Hall for citizens to use as cultural space City Hall to become Civic Center

12 Retrofit Existing Buildings billion KRW invested in BRP for 5 years; Saved 51k TOE/year Retrofit completed for 3,922 buildings (124 public, 770 commercial, 3,028 residential buildings) Central Post Office Samsung Gangnam Campus COEX Kyobo Tower Country s lowest loan for energy efficiency ( Loan adapted to building types (e.g. house, commercial) from 2 million up to 2 billion KRW

13 Size : 3,762 m2 Design: Technology + Landscape Techscape Combined landscape design by Fraunhofer with cutting-edge Korean technologies Rooftop and garden solar panels; Pinwheel-type design; Daylight in the court Feature: +70% energy saved, 30% from new and renewable (solar, geothermal) sources ZERO ENERGY Insulation, sealing and daylight to minimize energy consumption 2,721-KW Solar & 112-KW Geothermal energy for self-supply Concepts to be modeled after by new public buildings; recommended to private buildings

14 LED promotion for a City of Smart Lights City of Smart Lights by combining IT & lighting system Expanded supply of LED lights in the private sector - One-stop outdoor lighting control system (power switching & dimming) - Introduction of outdoor illumination level standards by revision of the Light Pollution Prevention Ordinance Apartments, large offices & underground parking lots 2m units Multi-use buildings e.g. supermarkets & department stores 5m units -LED Invest-firstrecover-later tool - On-line LED markets Expanded supply of LED lights in the public sector Substitution of signs, security lights in residential areas & street lights with highly-efficient lighting sources Public offices & road equipments 310k units Subway stations (100%) 479k units Underground shopping centers (100%) 25k units 7,000 signs using LED & solar cells 14,500 LED security lights in residential areas 17,000 low-capacity street lamps to be upgraded * Reinforced mandatory LED share for new buildings: 30~40% in % by 2014
