To maintain and develop high living standards for our citizens :
We have to :
- Reduce dependence on energy imports- Reduce contribution to climate change- Increase construction productivity- Add new properties to our existing materials / products / equipment (MPE)- Develop new MPE to ensure we meet European challenges : durability, lower energy use, sustainability, multifunctionality…

On Materials :
Understanding Chemistry and Physicsshould expand the limits of advanced materials and improve existing materialsNanotechnologieswill change materials sciences drasticallyBiotechnologyshould lead to the design of original materials with fascinating possibilities.Modeling and Simulationwill help design-to-purpose materials creation and virtual testing
Building products and systems combine and exploit the intrinsic characteristics of different materials.
In order to meet the various needs of the users, Equipment should be adapted to take into account the main European objectives and goals.

⇒ Lighting to suit one's needs : personalised based on the occupiers, the time of day and night
⇒ Heating and domestic hot water production
⇒ High-performance, low GHG emitting cooling equipment
⇒ New ways to store energy or heat are needed should lead to high performance skins
⇒ “On board intelligence“: The house should become sensitive with usefulintegrated sensors, ambient connection and prevention systems .
⇒ Water supply improvement : Water savings (rainwater,recycling…), modulablelayouts

50% building stock (existing buildings) are retrofitted with high standards of energy efficiency
New buildings are low energy consumption buildings from self sufficient buildings to net energy producers (Positive Buildings)
Technical and organisation innovations are needed
Technical solutions are not the same for the two markets
Energy Efficiency is a common necessity for these two markets

Retrofitting of existing buildings
• 2030 : Existing building upgrade reduces the supplied energy needs by a factor of 2 to 3
• technical innovations are needed :• advanced insulation products adapted to retrofitting specifications• efficient system dedicated to existing buildings (active windows, compact/integrated HVAC [ventilation, specific heat pumps], heat and/or electricity storage units, combined photovoltaic/heat solar collectors)• energy management at building scale (ICT) using general public communication infrastructure (mass audiovisual and computer equipments)• energy production (especially renewable ones) and energy storage included in existing buildings and adapted to retrofitting actions
• organisation innovations are needed :• new business models for retrofitting markets

New energy net producer buildings
• imagine, design, build and evaluate super energy efficient “concept buildings” : * bio-climatic design and summer comfort
* advanced thermal insulation techniques* air space heating
• affordability of solutions in order to reduce by 3 or 4 energy needs of new buildings : * 2010 : over cost less than 15%
* 2020 : less than 5% over-costs* 2030 : no over cost compared to today
• construction panels including energy production (especially renewable ones) and storage
• industrialisation of construction(manufactured envelope components)
• new buildings are a part energy network(consumption, production, storage, management)

Common needs for success
• to develop synergy between national plans, code and regulations and ensure convergence for all EU member states to high standards• to promote Energy Efficiency and Exergy optimisations (local taxes and legislations) and EU common performance criteria ( model code)• to accelerate technologies, best practices dissemination, and changes in building industry in a large variety of cultures and situations
• video-games-like soft-wares and low cost internet services• to build on IST for performance virtual evaluation of projects and new materials• to develop integrated, compatible, plug and play soft-wares• to develop data bases proposing typical solutions
• to organize a continuous sociology survey and adequate communication help managing acceptance of energy efficient solutions and adverse rebound effects (relaxed attention of users)• to promote PPP and cooperative schemes in a local context
