1 Active House B10 in Stuttgart, Germany Spark for an energy miracle Frankfurter Allgemeine Zeitung (July 18, 2014), paraphrased 1

2 About alphaeos alphaeos is a startup company located in Stuttgart currently comprising 16 employees Our interdisciplinary team develops predictive smart home solutions running advanced machine learning algorithms Customers across Germany, Austria, and Switzerland are now using our retrofitable predictive climate control system to save energy alphaeos AG,

3 Status Quo Carbon dioxide emissions of a 2- person household in Germany Estimated total retrofit costs to increase energy efficiency in Germany ~ 40.4 million housing units Electricit y ~ 35 million need to be renovated Fue l Home Heating Average floor area = 90.2 m 2 Renovation costs: /m 2 Assume average 500 /m 2 = (Quelle: Statistisches Bundesamt, eigene Berechnungen) alphaeos AG,

4 June 6, 2014 at 1:00 pm (Germany) Highest PV-output of 2014 (24.2 GW) Equivalent to about 20 nuclear power plants alphaeos AG,

5 Definition The term Aktivhaus ("Active House") stands for buildings, that can generate, store and consume energy together with other buildings in a selforganized network with the objective of achieving as much energy autarky as possible....that are able to actively react to changes in outdoor areas as well as indoors if these affect the energy performance of the building or the comfort of the user. alphaeos AG,

6 Active House B10 Research Areas 1. Seamless integration of electromobility with our built environment 2. Potential role of residential houses in the energy system of the future 3. Predictive energy management for buildings and electric vehicles Werner Sobek Stuttgart, Photos: Zooey Braun,

7 Active House B10 Project Overview Project Partners Project Sponsors alphaeos AG,

8 Location B10 is an abbreviation of the address: Bruckmannweg 10, Weissenhofsiedlung, Stuttgart alphaeos AG,

9 House by Richard Döcker at Bruckmannweg 10 The original house was destroyed during WWII and could not be rebuilt alphaeos AG,

10 Construction Site Due to regulatory restrictions on the site, a narrow floor plan was necessary alphaeos AG,

11 Construction Process The house was erected and ready for use in a single day Werner Sobek Stuttgart

18 Energy Concept Summary Forecast energy balance: 200% coverage of the house s own energy needs through building-integrated renewable energy generation High-performance building envelope while maintaining open and transparent architectural concept Optimized climate control and maximal use of on-site energy generation through intelligent energy management and building automation Efficient and resource-friendly heating and cooling system Connection to virtual power plant: Grid connection for energy consumption and surplus energy feed-in controlled through incentive-based pricing system alphaeos AG,

19 Energy Concept Efficient and Resource-Friendly Heating and Cooling System Forecast Heat pump uses ice storage tank and PVT-array as heat sources to maximize COP (Coefficient of Performance) Building cooling is provided in summer by using ice storage tank as heat sink Power for circulation pumps is generated on-site by PVT-array Large-area floor and ceiling heating and cooling circuits can be thermally activated with low supply temperatures The goq matrix hydraulic mixing and distribution system allows heat sources and heat sinks to be selected for maximum efficiency under varying conditions alphaeos AG,

20 Virtual Power Plant Integration Power consumption and supply are influenced by the virtual power plant to meet power grid requirements Example of demand-oriented power supply Power supply to grid in KWh Electricity price in /MWh Next Kraftwerke,
