  43. 43. Danke Schön 43 I am extremely grateful for this opportunity to learn and hopefully make an impact on both the Facility Management Unit and ALL of campus Westend. I’ve met several students from this campus and even people wanting to study here and everyone shows interest and support for my project. Wednesday, May 28, 14
  44. 44. SPECIAL THANKS 44 Dirk Seitz for getting the project going Milan Bosnjak for SAUTER & KNX Dieter Dreher for technical drawings and bulb information Rainer Born for LED lamps and tools Uli Ackerman guidance and support for installation of 14 LED lamps Steffi Lebedew for the Dienstfahrad Nadja Fabel for making me speak a little German Uwe Brede for interesting conversations and tours of the campus. Christoph Denecke & Detlef Wittwer for the initial/outline of the project at Campus Westend + Everyone Else Saaba for keeping my office neat :) ...also Super Bonus Double Thanks to Christoph Denecke for all his help and advice throughout the project (making introductions, translating everything, guiding & clarifying my questions and showing me around the campus and Frankfurt.- if this project is a success it is because of your kindness!
