AgendaEnergy Audit (Randy & Student Way)Savings StrategiesChecklist & Presentation Copy

The Basics: Energy AuditQ: What is an Energy Audit?Ans: Simply, an Accounting of energy use

Q: Audit Necessary to Obtain Energy Savings?Ans: No, but...

Q: Then why do it?Ans: Help identify best opportunities

More Basics: What Uses Energy?- Building- People- Building Guts

Before a (Physical) AuditDont guess about opportunities & actDo this instead:Get a (better) sense for whats importantSense what you can controlFocus approach/efforts accordingly

How?

Randy & Student Way

Energy Audit ApproachStep 1: Obtain Historical Energy Consumption

Step 2: Get Idea of how Total Energy breaks into Use Categories

Step 3: Verify (Assumptions) in Step 2 with (More) Research

Step 4: Visit Site: Verify Research & Look for Opportunities
