Wanted: Potential Savings
Large Retrofit Projects:Not scary!
Myth-busting:
• You don’t need previous experience to do this
• You won’t be coordinating the actual retrofits
• You won’t have to do all the calculations by yourself
So relax already…
What Am I Doing, Exactly?
You are helping your university identifygood places on campus for a retrofit. Facilities departments are often understaffed, and your research may help “spark” retrofit projects that were on hold/never would have happened.
Potential savings are valuable!
What You’ll Need
• Stakeholder support
• Strong math skills
• Willingness to ask questions and take feedback
• A good, feasible project
Find a Good ProjectMust be:
– Simple
– Worthwhile
– Measurable
– Of interest to stakeholders
• Ask around– Facilities stakeholders
• Look around– Be on the hunt for energy hogs on campus
Find a Good Project
Water ideas

Financial Analysis Metrics• Annual Savings
How many kWh/$/CO2 emissions saved per year as a result of
retrofit?
Calculate kWh savings Convert to $ and CO2
• Simple Payback PeriodHow many years would it take before the university makes its
money back?
Upfront costs ÷ Annual $ savings
Financial Analysis Metrics• Net Present Value
What is the university’s total profit from this retrofit, taking
into consideration project life and time value of money?
Discount RateUC 6.6%CSU 6.0%
Look for Rebates!
There are lots of rebates out there for energy efficiency retrofits
– Up to thousands of $$$– Rebates for universities– Check utilities website– Call and ask!
Run your calculations by someone!
(Someone knowledgeable)
– Stakeholders
– Alliance Staff
Calculations done! Now what?
Present your findings to stakeholders
• Report
• Presentation
Tips
• Come up with multiple strategies (2 or 3)
– Let them choose one!
• Show the pretty stuff (a.k.a. money)
– Only explain data and calculations if someone asks
• Cut to the chase
– Stakeholders have a million other things to do
• Be professional
– You are setting a precedent for Green Campus
Example

Giving a Presentation
• Accompanies the report
• May be more convincing
– (Not everyone may read the report )
• Number of audience members may vary
• Formal public speaking experience, yay!
