Smart Building Residential Wrapup of Breakout Session Problem

Smart Building (Residential) Wrap-up of Break-out Session

Problem Statement What is the distinction between commercial and residential? How Investment Decisions are made • Rational vs emotional • Business case driven vs convenience • Marketing “green” vs social status User – System Interaction • Trained facility engineer vs technically illiterate • Complex configuration vs out of the box, non-intrusive • Complete control vs optional control on demand Employee (work environment) vs owner/tenant (privat environ. ) Asset protection vs security and privacy Integration aspects: integrated systems vs smart verticals Large components vs. small components Security of supply vs independence of public infrastructure Lifetime 10 -12 years vs 3 -5 years 04. 12. 2020 Break-out group: Building (Residential) 2

What are the objectives of smart residential buildings? Comfort Cost reduction Status Independence of unreliable power system, self-supply (mostly US, to some extent in Europe too) • Capability to receive value added services • Maximize benefits at minimal user interaction • Users provide service themselves – potentially make money with it – just for feeling of doing something good to society • • 04. 12. 2020 Break-out group: Building (Residential) 3

Additional aspects Should sensor data be stored in the cloud? • + Easy investment • + remote access • - observe behavior at home • Private Customers must be in control of their data and the system. At least they must have the option. What makes smart home smart? • Helpful for the person that lives in it (visits it). • Elements can communicate with each other Scenario: You have a guest, all your devices are controlled from your smartphone. Control is automatically installed on guest’s device, and automatic deinstallation? 04. 12. 2020 Break-out group: Building (Residential) 4

State of the Art • On the Market right now technically – Many standards for communications barrier to invest • On the Market right now what is sold – Single verticals (services) are sold right now, integrated systems are not (Homatic, Qivicon, RWE, Plugwise, Q-loud, TADO, NEST, …) – Security and home automation systems – Metering feedback: En. BW cockpit, power radar, Vattenfall feedback … • Not on the market right now – No real plug and play of energy devices (as known for computers) – No optimization of schedules • At research prototype level – OSH, OGEMA, FPAI, IDE-Eclipse, Open. Energy Monitor • Users don’t see the advantage of integrated systems yet • Users only buy A++++ but not B (introduce green label? ) 04. 12. 2020 Break-out group: Building (Residential) 5

State of the Scenario • Percentage of buildings actually having these services is very low • DSL router is used for a variety of services. Internet, Media, TV. – Could smart home, energy be integrated? • Business model for solar panels has developed due to subsidies, now valid without subsidies. Incentive to self-supply, get independence 04. 12. 2020 Break-out group: Building (Residential) 6

Research Challenges • Human Computer Interaction – Adequate interfaces (user friendly), Psychologists collaboration needed • How to learn needs and requirements of the room / the user – Non-intrusive, lean, lightweight – E. g. , Smart Watch or what it will develop into as sensor on human – Humidity Sensors, CO 2 Sensors, Temp Sensor, – Sensors should be energy autarkic • Building Operating System - What do we actually need there? – Resource allocation necessary? – Serving as a platform for all the verticals vs. verticals cooperating without explicit platform service – Automatically created system ontologies? – central vs. decentral. One big centrally, or decentralized directly in the households? – Provided as a cloud service? 04. 12. 2020 Break-out group: Building (Residential) 7

Research Challenges • Develop business cases forecasting, recommendations • Interoperability – Standardization, Flexibility – Plug-n-play devices (automatic discovery), Device driver, Configuration • Legal Regulations. Who is reliable if there is a system failure? – The platform provider or the application provider or even the user? – Need agreement of users. Maybe non-intrusive is not possible 100% • Resource Management: which resources needed to realize Smart Home system? (LCA, lean or green technology) • Data management and Privacy. Where to put and process data? • Infrastructure vulnerability / safety – Authentication, who has the rights – Who is providing new software packages, updates etc? 04. 12. 2020 Break-out group: Building (Residential) 8

Short/Mid/Long Term Outlook Short 2018 • smart meters available for all early adopters • common infrastructure standardized/available for early adopters able to e. g. – host various analytics – remote control – grid integration (demand response involvement) • improved protocols issues Mid 2022 • Standardization achieved (grid integration, market integration) • Who could be home automation provider? – Telecom providers with their DSL routers – Entertainment companies with their Xboxes etc. – Probably not classical energy providers 04. 12. 2020 Break-out group: Building (Residential) 9

Long term outlook 2030 For users • Disappearing of technology (invisible) • Easy to use • Plug and play: Bring new device into the house and automatically integrated and system knows best usage of it. • No need to control temperature because system knows user’s needs. Some sensors need to know how you feel (smart watch) • Not single users only but also groups of people in the room. Negotiation of their preferences. 04. 12. 2020 Break-out group: Building (Residential) 10

Long term outlook 2030 General aspects • Energy aspect will not be as important anymore. Much more efficient and more generation. • Invisible intelligence, adapting services to user’s needs • Lot of generation and independence in smart residential areas. • Not much need for heating, because we know how to insulate buildings. Distance heat from power plants, compute centers. • Will energy consumption increase / decrease? – Germany: decrease – Indonesia 2015 160 TWh – 2030 300 TWh renew + 600 coal • No need for power transmission ? (decentralized systems only? ) 04. 12. 2020 Break-out group: Building (Residential) 11
