  1. Research and Innovation for Energy Efficient Buildings and Neighbourghoodsfrom a Lighting Perspective Bruno Smets S&I June 14, 2012

  2. Lighting position in the Building Value Chain Systemic approach

  3. Energy impact of Lighting Lighting accounts for 2.5% of the global energy use, but for 19% of all electrical energy amounting to 2600 TWh per annum Commercial buildings by far are the most important segment in terms of energy use and show the largest saving potential

  4. Digital Lighting – the Way Ahead • The demand for lighting will triple by 2050 due to the advent of the 24/7 economy • Even when all lighting is replaced by the most efficient technology available (i,e.: LEDs), the energy demand will nearly double from today. • Only by adding intelligence to this digital lighting technology, delivering the right light when and where needed, the energy demand for lighting can be stabilized at the present level

  5. Lighting Design + well developed skill vastly used for branding purposes - not integrated in the overall design process of most buildings

  6. Supplementing Day Light with Electrical Light Tour Sequana, Paris Bouygues Telecom 2,400 employees 45,400 m2 over 23 floors By balancing natural and artificial light the energy consumption is reduced by a factor of 3 to 4 with respect to the previous HQ building and this at a superior level of visual comfort

  7. Supplementing Day Light with Electrical Light

  8. Work Place Innovation Soundlight comfort, an acoustic ceiling integrated with LEDs - Concrete Core Activated buildings - Open plan offices

  9. Work Place Innovation The user at the centre of the solution living labs lack of comfort metrics + visual comfort - acoustics, air quality, thermal comfort

  10. City Touch

  11. Business and Organizational Innovation

  12. Digital Lighting enablingSmart Buildings & Cities Indoor as well as outdoor digital lighting systems form finely meshed networks, able - to adapt: guiding traffic & people, ambiance creation - to respond: emergency situations - to monitor: people presence and flow, traffic density By sharing information with other systems lighting can largely contribute to the realization of Smart Buildings & Cities

  13. Systemic Approach along the Building Value Chain • Requires standardization of components and tools • Facilitates the trade off between cost, speed and quality • Saves energy at higher added value (comfort, safety, …)
