6 Digital Home and Human Factors 10/22/04 Overall context n Sustainability awareness: n Reduction of Energy consumption ( Positive Energy Buildings) n Environmental issues n Societal issues e.g. quality of life, elderly and disabled people n Application to our living environment, including home buildings: n Low energy consuming n Comfortable n Safe n Secure n Nice-to-live (entertainment home) n Connected to the outside n Easy-to-exploit and (even) reconfigure/readapt

7 Digital Home and Human Factors 10/22/04 Past experience Home Automation (1990s) turned out to fail for several reasons: n High installation costs n Limited approach (mainly energy management) n Proprietary solutions n Not open and not reconfigurable solutions n No evolutivity and no adaptation to change in building usage or user profile n No real guarantee on durability

8 Digital Home and Human Factors 10/22/04 New context for Digital Home n Communication networks (wireless, RF, PLC…) easier installation, inter-connection of home networks with outside (incl. cars) n Protocols (IPv6, UPnP…) multi-addressing, auto-configuration, interoperability, flexibility n Electronics miniaturisation & integration n Power systems low consuming batteries… n Software architectures openness, flexibility, re-configurability…

9 Digital Home and Human Factors 10/22/04 Our vision for Digital Home n Information & electronics embedded in building components & equipments (together with sensors and actuators) n Building components become active, communicating and interoperable within a global system that provides advanced services related to: n Energy savings n Comfort n Health & Safety n Security n Elderly & Disabled people n Multimedia & Entertainment n Tele-Work n Exploitation & Facilities Management Economic, environmental & societal benefits

10 Digital Home and Human Factors 10/22/04 Our vision for Digital Homes (contd) n Open, distributed, flexible & (self)-reconfigurable systems that implement global and dynamic management strategies adaptable to user profiles & behaviour n New components can be easily plugged into an existing system automatic identification, self-configuration, behaviour automatically defined by local embedded strategy and/or global strategy n Existing components can be replaced by equivalent ones n Dynamic reconfiguration in case of component failure, temporary or definitive change of use strategy, etc. n Transparency and no/little parameterisation needed from the end-user n Low-cost solutions

11 Digital Home and Human Factors 10/22/04 Potential role for CSTB n Multi-disciplinary & global approach: Building Technologies, IC Technologies, Human Science n Independence from domain-specific industry interests n Industrial Facilitator in order to: n Develop & promote open standards and communication protocols, leading to potential for assessment and certification of home equipments n Develop communicating building components n Develop relevant management/control strategies

12 Digital Home and Human Factors 10/22/04 Some current R&D work n Partnership with W3Home (MBDS-UNSA) Mock-up of an integrated home gateway to assist elderly people in case of high temperature (2004) n Call Ademe/PUCA 2003 Exploratory study on active building envelopes n Call Ademe/PUCA 2004 Communicating objects for energy management (COMETE project, with INNO, MBDS,…) n Call PACA Laboratory for testing solutions supporting elderly people at home

13 Digital Home and Human Factors 10/22/04 Active Multi-function Envelope n Project funded by Ademe/PUCA (Call 2003 « Prepare Buildings for 2010 ») n Identify (and model) the various types of active building envelope components, together with sensors, that can be home networked to provide services to: n Reduce energy consumption n Optimise comfort (thermal, visual, acoustic, air quality) n Explore the software architecture that can support communication between those components n Define integrated management strategies n Several components used for a given service n A given component used for several services (e.g. presence sensor)
