overall context
Overall context
  • Sustainability awareness:
    • 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:
    • Low energy consuming
    • Comfortable
    • Safe
    • Secure
    • Nice-to-live (“entertainment home”)
    • Connected to the outside
    • Easy-to-exploit and (even) reconfigure/readapt
past experience
Past experience

Home Automation (1990s) 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
new context for digital home
New context for Digital Home
  • Communication networks (wireless, RF, PLC…) easier installation, inter-connection of home networks with outside (incl. cars)
  • Protocols (IPv6, UPnP…)  multi-addressing, auto-configuration, interoperability, flexibility
  • Electronics  miniaturisation & integration
  • Power systems  low consuming batteries…
  • Software architectures  openness, flexibility,re-configurability…
our vision for digital home
Our vision for Digital Home
  • 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:
    • Energy savings
    • Comfort
    • Health & Safety
    • Security
    • Elderly & Disabled people
    • Multimedia & Entertainment
    • Tele-Work
    • Exploitation & Facilities Management

Economic, environmental & societal benefits

our vision for digital homes cont d
Our vision for Digital Homes (cont’d)
  • Open, distributed, flexible & (self)-reconfigurable systems that implement global and dynamic management strategies adaptable to user profiles & behaviour
    • 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
potential role for cstb
Potential role for CSTB
  • Multi-disciplinary & global approach: Building Technologies, IC Technologies, Human Science
  • Independence from domain-specific industry interests
  • “Industrial Facilitator” in order to:
    • 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
some current r d work
Some current R&D work
  • Partnership with W3Home (MBDS-UNSA) Mock-up of an integrated home gateway to assist elderly people in case of high temperature (2004)
  • Call Ademe/PUCA 2003 Exploratory study on active building envelopes
  • Call Ademe/PUCA 2004 Communicating objects for energy management (COMETE project, with INNO, MBDS,…)
  • Call PACA Laboratory for testing solutions supporting elderly people at home
active multi function envelope
Active Multi-function Envelope
  • 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:
    • 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
    • Several components used for a given service
    • A given component used for several services (e.g. presence sensor)

component implementation through intelligent agents
Component implementationthrough intelligent agents
  • Agents have autonomous capacity to:
  • Adapt
  • Make decision
  • Auto-assemble
  • Co-ordinate
digital home for elderly people
Digital home for elderly people
  • Elderly and disabled people need to stay longer at home for social and economical reasons
  • Digital home can offer to them safer and easier-to-use environment
  • Proof-of-concept developed in W3Home according to a specific scenario
  • CSTB project for a laboratory to develop and test new solutions for elderly people:
    • Openness & interoperability
    • Reliability (through event correlation)
    • Collaboration with INRIA (Orion Team) for video analysis

  • Deployment of Digital Home needs a large acceptance & trust by users based on:
    • Pluggable & interoperable components & equipments
    • Extensible & reconfigurable solutions
    • Dynamically adaptable management/control strategies
    • Low cost systems
  • Market addresses not only new buildings but also existing ones
  • CSTB, thanks to its multi-disciplinary skills, has a role to play, together with industrials, to define & promote a reference technical framework that will allow the development of certified components, equipments and systems
