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

7 Digital Home and Human Factors

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

8 Digital Home and Human Factors

10/22/04

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

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

10 Digital Home and Human Factors

10/22/04

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

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

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

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)

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

Conclusion

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
