One possible project that we could take on would be to replace all the paper towels in the bathrooms with hand driers such as the Dyson airblade (really fancy and cool hand drier).
Here are some possible questions we might want to answer about the project.
How much do we spend on paper towels per week?
How many bathrooms are there on campus?
How much time does our sanitation staff devote to removing used paper towels from the bathrooms and installing new ones each week?
How much energy would a dyson hand drier use per week?
How much would that cost?
How much would installation cost?
How long do they typically last?
Repair costs?
So I found an ROI (Return On Investment) calculator.
