6 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting Advantages of HLG Lamp and Luminaire are separated Light Sources with high luminous flux can be used Maintenance is simplified, thus reducing costs Light (artificial and daylight) can be transported over a long distance Light can be coupled out uniformly

7 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting System scheme I Headmodule- Heliostat with EIB/LON-interface II Mixmodule- Addition of Sulphur Lamp Light Depending on the Available Amount of Daylight, EIB/LON-interface III Transportmodule- Efficient Light Transport With Hollow Light Guides with High-reflective Materials (OLF, Miro) IV Luminairemodule- Light Output without Glare sunlight modular construction and flexible dimensioning facilitate the integration in different buiding architectures

8 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting Sulphur Lamp  nonpolluting (no mercury)  continuous spectrum, close to sunlight Spektrale Verteilung der Strahlungsemission der Schwefellampe  low IR- and UV-Radiation  dimmable (20- 100%)  long lifetime  nearly flicker-free  high system luminous efficiency (90 lm/W)

9 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting Goniophotometer First Goniophotometer that can do photo- metric measurements on hollow light guides  Near Field Photometry (CCD-camera)  Automated Data Aquisition  Any shape of Cross Sectional Area  Maximum Length: 30 m  Maximum diameter: 0.5 m  Eulumdat-data Output

17 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting Prototype 2: Berlin Heliostat Sulphur Lamp Mixing Unit Lightpipes

18 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting The lighting should supply the staircase with a sufficient amount of light to use the staircase in a quick and safe way give good modelling to the people, meeting in the staircase provide good adaptation to the light quality in the connected rooms, which are illuminated by daylight (at daytime) Prototype 2: Berlin

19 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting Validation of Measurement Data Installation of a Lightpipe-system Measuring the Illuminance Distr. Photometry at the Lightpipe Simulation of the Illuminated Scene C:\ Comparison of the Results

20 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting Comparison with Light Plannning Software Tools Results of Comparison:

21 ARTHELIO - Project OverviewEnerBuild Thematic Group Meeting Enhancement of Visual Comfort in Deeper Building Interiors Reduction of Costs for Electric Energy, Heating/Cooling and Maintenance Development of a Heliostat For the Combined Utilisation of Both, Daylight and Artificial Light in Hollow Light Guides Optimisation of Hollow Light Guides by Analysing the Luminous Intensity Distribution Data Gained with the Goniophotometer Completion of a Design Guide as a Helping Tool for Lighting Planners, Architects and Engineers Expected Results
