Did you know?
About 86% of Penn’s carbon production comes
from building energy usage
If immediate action is not taken to reduce energy, Penn
will nearly double its total carbon emissions by 2050
Goal: Cut campus energy use by 17% by 2014

Project Description
The final product will be a quantitative model (e.g.
Matlab, Excel) and a simulation of Penn’s Heating
system where users can alter inputs of the existing
system to determine resource and cost savings.

Stakeholders
Considerations
University of Pennsylvania
Decrease the amount that Penn
spends on steam, while not changing
comfort level in buildings
Veolia Energy Corporation
Penn consumes approximately 40% of
its output
Philadelphia Community
City water is wasted to quench the
condensate to 140oF
