Ecological Footprint
Technical Financial
Calculating the ecological
footprint should be the next
step in the modernization
process along with testing the
replacement of existing bulbs to
LEDs
The eco footprint is
important because the
embedded energy of LEDs is
very high so the REAL (non-
monetary) savings are less
than we think they are.

Two leds were chosen.The
Philips CDMT to replace lamp
type A and G12 -10 to replace
lamp type B

The Plan
41
Modernizing is really inexpensive and
relatively fast to perform
The ROI is within the bulb warranty
Risk is low, gain is high
Purchase sample bulbs from
Chinese Suppliers (3-4) and redo
what I did with Uli with different
light ﬁxtures
Test for
quality and
performance
Order and replace old bulbs
with new LEDs
Win

Thoughts...
42
•
Point lights towards the foot path, not the grass
•
Optimize system for locating and changing
broken lamps
•
Use Mapbox to track bulb lifetime
•
Use Mapbox to track changes (if no other
system is in use)

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.

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
