Apr 2006COST529_0406.ppt1 Collaboration in the science & technology of lighting post-COST529 Stuart Mucklejohn COST529 UK National Representative British Titanium plc, 24 Old Queen Street, London SW1H 9HP, UK COST 529 Management Committee meeting 02 April 2006, Mierlo, NL

Apr 2006COST529_0406.ppt2 Why was COST 529 successful ?  Leadership  Funding  The people involved  Wide range of scientific & technical interests  Many nations  Mix of academia/industry/government laboratories  Willingness to exchange information  Willingness to host meetings  STSM

Apr 2006COST529_0406.ppt3 How to continue to be successful ?  Retain attractiveness to industrial partners  Stay relevant and topical energy consumption environmental aspects (disposal, re-cycling) quality of light  Ensure there are some tangible outputs  Avoid the perception of being academic only  Do not divorce light sources from lighting  Update-to-date web site  Be known as a valuable source of information  STSM

Apr 2006COST529_0406.ppt4 ‘Never going to go away’ topics  Fundamental data  Diagnostic measurements  Solving materials problems  Evaluating new materials  Models  Education  Learning  Training  Conferences

Apr 2006COST529_0406.ppt5 New opportunities ?  Metal halide lamps with ceramic arctubes  Corrosion and other aspects of material transport  Chemical kinetics  Vision in the mesopic region  Life cycle assessment (LCA)  Other European lighting organisations

Apr 2006COST529_0406.ppt6 The COST standard lamp  Diagnostics  Model validation  Electrode design  Lamp – ballast interaction  Lamp chemistry ? What about material transport & corrosion ?  Ceramic standard lamp Design & build or Commercially available product – selected randomly

Apr 2006COST529_0406.ppt7 The mesopic range  Photopic: Luminance >10 cd.m -2  Scotopic: Luminance <0.01 cd.m -2  Mesopic: Luminance 10 cd.m -2 to 0.01 cd.m -2  Why is the mesopic range important ? Road lighting Emergency exit route lighting  No system recommended by CIE for mesopic photometry  Why not ? No internationally accepted eye sensitivity for mesopic range  Why not ? ? but the response of the eye does change in this range  Can we do anything ? Yes !!!!

Apr 2006COST529_0406.ppt8 Life Cycle Assessment System componentsTopics  Lamps  Energy consumption  Ballasts  Production  Control gear  Disposal  Fixtures  Recycling  Replacement strategy LCA for CFL compared to Incandescent for domestic use

Apr 2006COST529_0406.ppt9 Embodied energy From the 2004 CIBSE National Conference Delivering Sustainable Construction David Arnold (Troup Bywaters & Anders): ‘Embodied energy of a building is the energy used to acquire raw materials, manufacture, transport and install building products in the initial construction of a building’ ‘Recurring embodied energy of a building is the energy required for maintenance, repair and change of use’ ‘Operating energy of a building is the energy required to operate the building’ (heating, cooling, ventilation, lighting, powering equipment)

Apr 2006COST529_0406.ppt10 Embodied energy - Lighting Suggested definitions ‘Embodied energy of a lighting system is the energy used to acquire raw materials, manufacture, transport and initially install all components of a lighting system’ ‘Operating energy of a lighting system is the energy required to operate the system including the replacement, removal, transport and disposal of components’ Broad themes of sustainability: Environment; Economic; Social
