2 Cities are the growth engines for their national economies Megatrends imply significant challenges for city decision makers Megatrends Globalization & Urbanization Global players / trade volume increase 2030: 60% of population in cities Energy / buildings / mobility / water infrastructure are key Demographic Change 65+ generation will nearly double by 2030 (from 7% to 12%) Need for adequate infrastructures as well as health- and elder care Climate Change Cities responsible for ~80% GHG Need for resource efficiency and environmental care Sustainable Urban Development Cities are competing globally to make their urban areas attractive to live and to invest in Environment Competitiveness Governance Quality of Life Challenge to balance between competitiveness, environment and quality of life, and to finance infrastructure solutions Page 2 Siemens ltd All rights reserved.

3 Siemens insights into "how to become sustainable", jointly developed with major world cities Perception studies Comparative studies Megacity Challenges Comprehensive analysis based on interviews with over 500 city managers in 25 selected megacities Urban infrastructure trends and challenges as well as global best practices New: The Sustainable Cities Challenge in Canada ICT for City Management Green City Index Index compares cities across 8 dimensions of sustainability: CO 2, Energy, Buildings, Transport, Waste & Land Use, Water, Air, Governance Started in Europe, rollout in Africa, Latin America and Asia Implementation studies Sustainable urban infrastructure series How to become a sustainable city" with focus on measures for resource efficiency and CO 2 abatement Examples: London, Munich, Yekaterinburg, Dublin, Trondheim,...

5 Energy is a key element of sustainability 2008 Fuel use shares in Ireland 2008 Primary Energy Demand 4% in Ireland 5% 9% Coal Oil 27% Gas Peat 55% Renewables 2025 ESRI Baseline of 2025 Baseline projection of fuel use shares in Ireland Primary 1% Energy Demand 6% 8% Coal 26% Oil Gas Peat 59% Renewables 96% of Ireland s primary energy based on fossil fuels >90% imported 70% of world supply from just a few countries End of pipe Growing demand competition from developing countries Oil at $80 during a recession Page 5

6 Potential for sustainable solutions Wind and Marine other sources? Biomass, biofuel Solar thermal Improved Solar PV Challenges Management Export New smart techniques Source:Eirgrid Page 6

7 Paradigm Shift in Power Grids Smart Grid Page 7

8 Smart City : ICT to enable sustainable behaviour As a fifth utility, ICT can enable increased efficiency and flexibility to use new resources. ICT has to come down from the cloud to where resources are used Page 8

9 Smart Grid needs Smart Buildings Page 9

10 Technology for a sustainability culture Green Building Systems informs and sensitises staff to energy saving Regular tips and reminders can achieve a further 10 15% saving information for further optimisation and fault management Interface to Smart City and enabler for new solutions Page 10

11 Sustainability can be self-financing Vienna: 300 municipal buildings have energy management contracts 20% energy reduction, 40,000 T CO 2 7 million savings per year Page 11

12 Buildings Issues Energy consumption / GHG emissions Facts and figures Globally: Buildings consume 41% of all world-wide energy; buildings are responsible for 21% of all CO 2 emissions London: Residential and non-residential buildings account for 67% of city's CO 2 emission (31.5m tons) Dublin: Energy audits find new buildings built with up to 30% savings potential. Life-cycle considerations On average, 20% of total life-cycle costs arise during planning and construction of a building, 80% during its usage (~50 years) During usage, 40% of cost are for energy consumption, 60% for facility management and maintenance Costs for energy efficient or green buildings With additional costs of less than 2%, energy consumption for new buildings can be reduced by 37%. Achieving the green building LEED "certified" standard requires marginal costs of 0-3%. However, average perception is that a 17% cost premium would be necessary to reach such level. Buildings are key to energy efficiency in cities Source: WBCSD EEB; USGBC Page 12

13 Not just for commercial buildings Source: ESB Connected Home as Smart Living interface for individuals Page 13

14 A Connected Home is a Smart Home Automatic responses to network signals for: tariff optimisation inhibiting / starting appliances night storage and EV charging Automatic adaptation to occupation and activity as well as schedules. Challenges and opportunities: Reducing user input and making it more user-friendly Adapting packages for refurbishment and new build Page 14

15 Sustainability and quality of life go together - lighting Issues Phase out of inefficient products Facts and figures EU: Climate protection targets will lead to phase out of inefficient products. (ErP-Directive 2009/125/EC) LED: new products for improved efficiency and adaptability Growing Demand for Safety and Security UK: Increased street lighting levels decreases crime by as much as 30% (UK Home Office Research Study). Adaptive street lighting to react to presence White light for true colour and reduced glare Better lighting improves activity of dementia patients Austria: Study in a Vienna nursing home showed day cycle light control gave a better quality of life for residents and for staff Concepts for intelligent and energy-efficient lighting Page 15

16 Traffic Reduce, Re-use, Re-direct Issues Public Transport reduces emissions and saves road space Internal combustion engines very wasteful in cities Facts and figures Global: Average energy consumption of passenger cars is 0,6 Kwh per passenger and kilometer driven Global: Average energy consumption of buses is 0,2 kwh per passenger and kilometer driven London: Hybrid buses will reduce consumption by up to 40% Germany: 14 bn. litres of fuel per year, or 17% of total vehicle consumption are wasted in jams or slow moving traffic Solutions: EV and plug-in hybrid use no fuel when stopped in traffic and re-use braking energy Solutions : EV can re-charge from renewables at night Information gives commuters better options Germany: A traffic center developed and implemented by Siemens forms the basis for efficient mobility management across Berlin. The intelligent processing and aggregation of data from thousands of sources is a key part of the system. Page 16

17 A Smart City acts smartly We know what we need to do We have the technology to do it Sustainable financing is possible Energy Source Buildings & lighting Transport We need to move now We need to develop new business models - To support the various measures - To encourage private investment The value-add in implementing resource saving measures and developing new solutions can deliver sustainable economic development with export potential.
