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

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

New context for Digital Home n n n Communication networks (wireless, RF, PLC…) easier installation, inter-connection of home networks with outside (incl. cars) Protocols (IPv 6, UPn. P…) multi-addressing, auto-configuration, interoperability, flexibility Electronics miniaturisation & integration Power systems low consuming batteries… Software architectures openness, flexibility, re-configurability… Digital Home and Human Factors 10/22/04 8

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

Our vision for Digital Homes (cont’d) n Open, distributed, flexible & (self)-reconfigurable systems that implement global and dynamic management strategies adaptable to user profiles & behaviour n n 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 Existing components can be replaced by equivalent ones Dynamic reconfiguration in case of component failure, temporary or definitive change of use strategy, etc. Transparency and no/little parameterisation needed from the end-user Low-cost solutions Digital Home and Human Factors 10/22/04 10

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

Some current R&D work n Partnership with W 3 Home (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 Digital Home and Human Factors 10/22/04 12

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