Title: Energy Efficiency


1
Energy Efficiency Smart Buildings-The
European REEB project
  • IMS Workshop, Bern, 24 April 2008
  • Alain ZARLI Marc BOURDEAU - CSTB
  • Matti Hannus - VTT

2
Energy main concerns
  • Known reserves (at 2008 rate of consumption)
  • Oil/Petrol 40 years
  • Natural gas 70 years
  • Uranium 80 years
  • Coal 230 years
  • Sun Wind forever
  • EU imports 50 of its energy from unstable
    countries
  • 50 of savings to meet Kyoto objectives can be
    obtained by EE in Buildings Construction

3
Basic characteristics of the construction sector
  • Total annual turnover 910 billion (EU-15).
  • 12 million workers 7 of total employment 28
    of industrial employment.
  • 26 million workers depend in some way on
    construction.
  • Construction, operation and maintenance of
    facilities is 20 of GNP in idustrialised
    countries.
  • 40 of all material resource consumption.
  • Large amount of waste, one tonne per capita
    annually.
  • One million site accidents occurred in 2003
    (EU-15) causing one thousand casualties.
  • Life cycle costs are dominated by operation and
    maintenance while design construction are less
    than 25.
  • Indoor conditions impact on productivity, comfort
    and health.
  • Fragmented sector No dominant players
    Non-professional customers Local regulations
    Focus on lowest investment cost Performance of
    buildings is mostly driven by regulations instead
    of market demand.

4
Energy consumption of buildings
  • Heating and lighting of buildings account for
    40 of all energy consumed in Europe.
  • Construction activities account for 5 of energy
    used, including construction related transport.
  • Buildings the largest source of CO2 emissions
    (1/3) in the EU-15 (if their electric power
    consumption is included).
  • Trends towards increased use
  • Air-conditioning due to climate change.
  • Raising standard of living.
  • Increasing building stock.
  • Annual energy consumption in residential
    buildings
  • 100-250 kWh/m² - Western Europe.
  • 250-400 kWh/m² - Eastern and Central Europe.
  • 50-100 kWh/m² - Northern Europe, well insulated
    buildings.
  • lt 20 kWh/m² - Passive houses.
  • Only 1-2 of building stock is renewed annually.
  • ?Energy consumption of buildings in the next 50
    years can be reduced mainly by renovating the
    existing stock.

Buildings Energy saving with...
  • (structure) More efficient envelopes
  • Use of improved materials
  • Integration of renewable energies (natural
    ventilation, solar thermal collectors, solar
    photovoltaic panels, wind turbines, )
  • Improved (ICT-based) design with advanced
    software simulation
  • (equipment) Better equipments systems
  • lighting, electric devices, HVAC, improved
    monitoring control (with systemic approach),
    adaptive Energy Management systems / services
  • Intelligent energy building / district / urban
    networks
  • and improved / changed individual collective
    behaviors!

10
Energy buildings / ICT support An example
Common data model
  • Dynamic building simulation provides information
    to select the best technical solutions (in terms
    of optimal energetic behaviour of the building)
  • ? A common data model is necessary
  • To avoid the huge amount of work required to
    input simulation data
  • To foster interoperability between simulation
    tools, building code related tools and
    dimensioning tools and to lead to optimisation.
  • The next generation tools will consist in the
    development of a global solution for evaluation
    and design, which integrates various aspects of
    energy, air quality and comfort, environmental,
    socio-economic, etc...
  • ? Need for an integrated multi-disciplinary
    approach

11
Energy efficiency building Issues, barriers,
challenges
  • Harmonized, scientifically valid eco-label for
    energy use
  • Continuous improvements in standards
    regulations
  • Empowering consumers to control manage their
    energy consumption/demand
  • Intelligence in energy management systems for
    controlling / optimising energy interacting
    with users
  • Smart building technology showcases /
    demonstrators
  • Citizen awareness of environmental sustainability
    issues
  • Increased dissemination of the know-how
    technologies towards contractors, enterprises,
    and even crafstmen
  • User-friendly interfaces with energy saving
    applications
  • Interoperability semantics
  • Business incentives (and proved energy-saving
    business cases?)
  • Methodology for impact assessment defining the
    indicators, getting the information, etc.
  • Getting together with the whole value chain

12
SOTA, technical non-technical barriers towards
operational RD results
  • Already quite a set of initiatives RD works
    targeting aspects of home and building automation
    / electronic systems and in relation to the
    Information Society
  • E.g. CENELEC TC 205 (Home and Building Electronic
    Systems), KONNEX (KNX technology standard),
    ECHELON
  • But
  • Still a lack of widely adopted technologies
    standards to ensure integration of a wide
    spectrum of control applications and the control
    and management aspects of other applications in
    and around homes buildings
  • Still a need for identification development of
    new devices, and necessary hardware and software
    interfaces
  • Still a need for harmonized performance
    requirements
  • Lack of digital home / smart building technology
    showcases, demonstrators (living) laboratories,
    in-situ experimental houses buildings

    water,) and to optimise the indoor climate
    conditions.
  • ICT support to global/local strategies in
    distributed systems
  • Energy efficient systems will be defined as
    decentralized systems in which the energy is
    considered at building and district scale,
    establishing new energy management relations
    about the energy grid, the building, the district
    the city.
