Smart City Expo World Congress Barcelona, December 1 st, 2011



Population Growth

In 2007 ~ 50% of the world's population was living in cities, an increase from 3.5 B to 4.7 B until 2030

Cities as Powerhouses

50% of world GDP is produced in cities with a population over 750,000

Major energy and climate factor

75% of energy consumed in cities; 80% of CO2 emissions are produced in cities

We are in the “urban millennium”



Cities are committed to CO2 reduction targets

Carbon-neutral 3

1. Target for Munich per capita against 1990 level 2. Relative target for China per unit of economic output (GDP)Carbon-neutral means that the city can offset its emissions by investing in Kyoto Protocol-style

projects that reduce pollution elsewhere (Source: Desk research; team sustainable cities)

Growing electrification is leading to a power matrix



Electromobility: clean, quite and efficient – mobility of the future!

�Challenges like scarcity of raw materials, global warming, and urbanization cannot be met by fighting the symptoms. They require sustainable, comprehensive solutions that will enable us to achieve our development goals while also preserving our natural resources.

�From a climatic perspective, the quiet and emission-free electric vehicles are ideal for urban environments. Furthermore they are the only means of travel that can provide both clean and highly individualized mobility.

Electromobility technology platform



•The space-saving charging solution, versatile and reliable.Wall boxes

Solutions for moving with Energyinto a mobile future

•Modular Charging Points for customized functionality•For public or private charging locations, across a campus orin retail and industrial areas.

Charging points

•Charging, payment and information functions combined in one stationSatellite systems

•Providing flexible point-of-use service solutions for routing, charging, reservations, and payment. Software suite

Energy savings up to 40% are possible

� Energy consumption (heating, cooling, ventilation, hot water …)

� On-site energy generation(solar, wind, geo-thermal …)

� Efficiency in the building(lighting, air-quality …)

Visit our stand: the Crystal - London

What we know about buildings …Building automation can reduce energy consumption



Example Smart Building: Energy saving is possible i n every type of building and in every business

Note: High energy efficiency (Class A) compared to standard equipment (Reference Class C) EN 15232—Impact of BACS and TBM on energy performance of buildings
