Future European activities in Energy Efficient
Lighting of Buildings Proposals for efficient
programmes and coordination.

Preliminary observations 

• In artificial lighting, European industry leads
  the world regarding the performance of the
  luminaire industry and the control technology. In
  countries such as Germany, Netherland, or
  Swizzerland the standards for efficiency are
  quite high, but they are progressing all around
  Europe.
• For indoor lighting, T5 fluorescent with
  electronic ballasts represent the best light
  source in terms of efficiency, with no real
  potential of improvement for the next 20 years.

Preliminary observations  (continued)

• Good news for energy conservation Halogen
  spotlights will me replaced in the next 5 years
  by LED sources, coming from the electronic and
  computer industry. Danger Europe will probably
  loose its leadership to Asian companies but
  Philips, Siemens invest strongly on these
  technologies.Major potential for energy savings
  will come from1) generalization of best
  practice high quality, low power densities2)
  turning lights off whenever it possible (in
  relation to occupant needs, presence, and, above
  all, daylighting)

Type of activity needed 1) RD

• Efficient and powerful task lighting using T5
  technology this should increase lighting
  quality, offer more flexibility, and reduce
  power densities in offices from 15W/m2 to below
  10W/m2 or even below 8W/m2.Highly insulative
  glass, to allow use of larger glazed areas and
  more daylighting.
• Optimized solar shading techniques and their
  controls
• (between glass panes?)
• Deep daylighting techniques (Passive light
  guides, façade components)

Type of activity needed 2) Dissemination

• Examples of very efficient and very sustainable
  work place in offices. Below 70 W / person for
  electrical lighting power incomparison with
  200W/m2 current. Highly controllable, default
  controls for energy savings. Industrialize the
  solution with office furniture manufacturer.
• Propose demonstration buildings
• Document the results
• Involve major clients (banks, public
  organization,etc.)

Brussels, February 8th
6
Type of partnership needed

• Academic performance targets, monitoring
  procedures, laboratory tests, occupant
  satisfaction, sustainability assessment
• Industrial supply of products, increase
  performance, integration reduction of costs
• Governmental health organizations, work
  legislation
• Clients investors in the field of buildings
  (office / industrial, banks, governmental
  organizations)

Brussels, February 8th
7
Type of project

• The efficient office space of the XXIth century
  sustainability (energy material), pleasantness
  (occupants), low cost (market integration).
• Facade systems using as much natural radiation,
  light and air and leading to less discomfort for
  occupants.
• Roof systems using as much natural radiation,
  light and air
• Building management systems using internet, and
  climatic ressources (satellites and ground
  stations) ,to optimize energy efficiency of
  systems.
• Coupling of LED and PV

Brussels, February 8th

Targets in Lighting

• 6W/m2 office lighting, less than 6KWh/m2.year
  average
• Workspace below 50 W
• New LEDs with efficacy higher than 50 lm/W
• Replacement of all compact fluorescent and
  halogen by LED (no moremercury)
• Use of daylight for ambient lighting up to 70
  of needs
• (map of Europe)
