An energy auditor walks through a building, finds where energy is wasted, and tells the owner which fixes pay off. You do not need a degree to start. Most auditors enter with a high school diploma plus a short certificate and some field training. The path has three steps. First, learn how buildings use energy (envelope, heating and cooling, lighting). Second, learn to measure, calculate savings and write a clear report, and earn the credentials employers ask for, such as BPI Building Analyst. Third, move into commercial and industrial audits (ASHRAE Level 2 and 3), where you model energy use a

Stage 1 of 3 · about 10 weeks
Understand how a building gains and loses energy, and do a simple walk-through audit of a home.
Building science basics
Every recommendation rests on how heat, air and moisture move. If you know that heat flows from warm to cold, that air carries heat and moisture, and that insulation slows heat flow, you can explain why a leaky attic costs money.
Reading utility bills and energy units
Bills are your first data. You must convert between kWh, therms, MMBtu and dollars to compare fuels and see what a building really uses.
Heating, cooling and water heating systems
Mechanical systems are often the largest energy users. You need to read efficiency ratings (AFUE, SEER2, HSPF2, EF/UEF) and spot signs of poor operation.
Spreadsheet skills in Excel
Auditors spend much time calculating savings, payback and charts. Excel (or free Google Sheets) is the daily tool.
