33 Validation User Comfort and Acceptance excellent good Support of Visual Tasks Light quality for visual tasks Differentiation of objects Colour rendering of objects and skin tones average Room Appearance Visual impression Lighting design / luminaire arrangement poor very bad overall impression support of visual tasks room appearance visual comfort well-being user friendliness Visual Comfort Light level Glare Colour temperature Light distribution Well Being Mood Vitality Motivation User Friendliness Number & quality of light scenes Personal and autonomous control 33

34 Validation User Comfort and Acceptance Average Rating per Room Rating per Luminaire excellent excellent good very good average average poor poor very bad guest room corridor bath room very bad wedges luminous door spots 34

35 Validation User Comfort and Acceptance Customer Behaviour yes, definitely 4 mostly yes 3 it depends... 2 mostly not 1 no, definitely not Would you prefer a hotel with this kind of lighting? 0 How much would you additionally pay for it? 35

36 Conclusions Lighting Quality and Comfort 20% * Luminaire Efficacy 42% Intelligent Control > 80% Energy Savings 36

37 Conclusions Next generation lighting network Distributed intelligence Smooth configuration and scaling of network nodes Cooperation of intelligent luminaires adapting to changes in the environment Intra-luminaire bus architecture Plug-and-play configuration Product diversity handling Leverage design freedom enabled by LED technology Hospitality system demonstration 81% energy savings exceed best in class benchmarks User ratings in favour of EnLight system 37
