Megatrends The world's toughest questions
It’s getting warmerHighest CO2 concentration in the last 350,000 years
We’re living longerAverage life expectancy increased from ~35 years to ~65 years within one century
There are more people in citiesIn 2050, 9 billion people will live on our planet; many in cities
We’re doing business in more places GDP of Least Developed Countries has tripled within the last 20 years

What we know about cities
Megatrends pose urgent challenges to cities
Cities cover less than 1% of the earth's surface but are disproportionately responsible for causing climate change
Currently, around 50% of the world’s population live in cities. Until 2030, 60% of the world's population growth will occur in cities
Cities consume ~ 75% of the world's energy and are responsible for up to 75% of GHG emissions and account for 60% of the world's water use

Zero net energy buildings …Holistic approach can also save significant energy
Energy consumption (heating, cooling, ventilation, hot water …)
On-site energy generation (solar, wind, geo-thermal …)
Storage (building hull, water tanks)
Efficiency in the building(demand control, lighting, air-quality)
Zero net energy buildings are coming: CA 2020-2030 / EU 2018

Energy saving possibilities
1) High energy efficiency (Class A) compared to standard equipment (Reference Class C) EN 15232 – Impact of BACS and TBM on energy performance of buildings
Energy savings are possible, in every building – in every business

Energy Efficiency in buildings is also profitable
Value of efficient buildings
Green Buildings are 0-5% more expensive
• Approx. 500 buildings analyzed in USA with Energy Star or LEED certification
• Compared with 10,000 buildings with similar location and quality standard
Financial benefits
Overall, 6% higher rental rates
16% higher selling price

The solutions is centered around an intelligent building energy management system that controls consumers, storage and on-site
generation. Goal is to shift loads for energy cost reductions

Building operators are incentivized to shed loads
Few occasions p.a., usually on hottest days
Primitive technical solutions with manual interaction and notification
Unreliable user behavior leads to need of high over-subscription
Load shedding usually results in comfort loss
Today 6% of US peak load are under contract

From few events per year to daily interactions
From primitive load shedding to long-term load shifting and co-generation
From incentive based Demand Response Programs to Real-Time Pricing
From manual interaction to fully automated interactions
Financial Benefit for Building Operator will increase dramatically
Changes in Grid InteractionVolatile Renewable Energy
The Next Generation of Demand Response has to deal with volatile renewable energies
Example of Denmark shows that wind-energy already exceeds demand!

>80% of installed base in Germany Energy efficiency is insufficient
History of energy saving policyin Germany
Regulation sets energy efficiency standards
Implementation is even better
But far away from possibilities
• New buildings are energy efficient, but…
• 80% of installed base is far off..
• Survey beyond 400 companies 56% will invest in energy efficiency in the years to come

Conclusions
Smart consumption can reduce emissions by ~75%; save billions in avoided energy costs,
capacity additions
No need to invest in new technologies; all the tools and technologies we need are already
here
Financial tools and regulatory / legislative environment set to help movement succeed
