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

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)

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.
