3 Future Energy Challenges Growing demand High share of renewable energy +63% 20,300 TWh 68% 2008 Fossil energy sources 33,000 TWh Renewables Nuclear 54% % 2020 EU-Directive for renewable energy hydro, wind, solar, geothermal, biomass Decentralized energy production Stochastic energy flow Peak demand Shaved peak demand Page 3

4 41% of world energy consumption in buildings 59 % 41 % Buildings 35% Nonresidential Ventilation Air Conditioning 23% 15% Other process heat Others 65% Lighting 6% Hot water 10% 46% Heating Buildings account for 41% of global energy use Around 35% is attributable to non-residential buildings (trade / industry / services) Page 4

5 Grid and building have entered the development phase of becoming "smart" Evolution of grid and building 3 Smart Traditional 1 Central Generation Central generation plants Central T&D concept Building Control HVAC Control Pneumatic technology Prosumer 2 Decentral Generation Political trend towards renewable decentralized generation (e.g. EEG) First pilots for wind and PV generation plants Building Automation Building Management System Integration of other technical subsystems, e.g. PV Smart Grid Pilots Testing of Virtual Power Plant (VPP) concepts in Europe Establishment of Demand Response market in US First Microgrid pilots First smart metering roll-outs Building Performance Energy Efficiency Total Building Solutions Remote building and energy management First demand response applications (Sitecontrols) Smart Grid Efficient integration of renewable & distributed generation by VPPs Trend towards decentralized grid structures Large smart meter installed base Distribution automation; full know-ledge of grid status down to LV-level Smart Building in Smart Grid Intelligent energy consumption Energy supply-side management Local energy generation Energy storage Interface to smart grid Source: IC BT / SG project team EEG = Erneuerbare Energien Gesetz Page 5

6 Smart Buildings manage optimally local consumption, generation and storage, by providing detailed monitoring Smart Buildings components Smart Building Energy Efficiency Reduced energy consumption at highest comfort, improved sustainability Application examples Heat generation with heat pump Air distribution Temperature control with blinds Brightness control with lighting Smart Building Total building solution including local generation, local storage, power management and e-mobility Monitoring, Controlling & Forecast Detailed monitoring and forecast about building s processes Energy generation and storage Optimal management of generation, consumption and storage, incl. e-mobility Communication with smart grid Interpretation of monitored data Forecast for consumption, generation, storage Building transparency Page 6

7 Focus on technical building equipment makes economic sense (Example London) Abatement potential [Mt CO 2 ] Investment [ Milliarden] Abatement/Investment ratio [kg CO 2 / ] Insulation Heating Ventilation Lighting Appliances Other Source: "Sustainable Urban infrastructure, London Edition A view to 2025" Page 7

8 Smarter buildings leverage automation systems Smart Building types Residential <100 kw connected load <30 kw de-central generation peak capacity Single-/two-family homes Large commercial buildings >1,000 kw connected load <1000 kw de-central generation peak capacity Large office buildings, hospitals, universities >10,000 m² <1,000 kw connected load <200 kw de-central generation peak capacity McDonalds, Walgreens, Multi-family homes 1,000-10,000 m² Light commercial buildings >1,000 kw connected load <10 MW de-central generation peak capacity Factories, Industrial Page 8

9 Pilot projects in Europe Malmö Hyllie Virtual Power Plant (VPP) solution Distributed Energy Management System (DEMS) integrating buildings with building automation systems as flexible load (Start 2012) R&D Project EcoGrid Bornholm (DK) Participation of in large-scale smart grid demonstration project ( ) Page 9

10 Pilot projects in Austria Seestadt Aspern Smart buildings in Smart Grids Local and regional optimization at selected construction sites (Start 2013) Smart Grid Smart Grids Model Region Salzburg Smart Buildings are active elements of a Smart Grid Pilot project with 10 Smart Buildings (Salzburg Wohnbau) Smart Building Active participation Power grid Management Power grid Optimization Bidirectional communication Building Management Building Optimization Page 10

11 Flexibility in buildings - Marketing opportunities Peak demand limiting Tertiary control reserve 15 MW Control reserve market Minimal offer 10 MW 5 MW DSM-Aggregator Secondary control reserve Spot market Balance group settlement Minimal offer 10 MW Monthly tendering 5 MW Weekly tendering Page 11

12 Value of a Smart Building in a Smart City Peak load reduction Load shifting Co-generation / storage Cost and CO2 reduction Optimized network planning Energy consumption optimization Integration of renewable energy E-mobility charging Page 12
