Why Energy Efficiency?

• Slow down climate change

• Reduce impact on the environment

• Save resources

• Save money

• Be more practical

This is my STARTUP


6

ShowerMagic is a ShowerWater filter that cleans and reuses water

To save water, energy and the environment

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.

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

Dirk Seitz for getting the project goingMilan Bosnjak for SAUTER & KNX Dieter Dreher for technical drawings and bulb informationRainer Born for LED lamps and toolsUli Ackerman guidance and support for installation of 14 LED lampsSteffi Lebedew for the DienstfahradNadja Fabel for making me speak a little GermanUwe Brede for interesting conversations and tours of the campus.Christoph Denecke & Detlef Wittwer for the initial/outline of the project at Campus Westend

+ Everyone ElseSaaba 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!
