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

Stakeholders


Stakeholders Considerations

University of PennsylvaniaDecrease the amount that Penn spends on steam, while not changing comfort level in buildings

Veolia Energy CorporationPenn consumes approximately 40% of its output

Philadelphia CommunityCity water is wasted to quench the condensate to 140oF
