Home Energy Audit Cost Guide

Inside the actual 64-page edition

This original handbook follows a complete planning sequence: preface, assessment scope, actual bills, tariff and context records, recommendations, coordinated packages, verified funding assumptions and outcome review. Chapters 2–20 each contain an explanation, an accurately worked hypothetical example and a dedicated planning sheet. The PDF has 95 fillable text fields across 19 worksheets, plus printable space for handwritten notes. Fields do not calculate automatically.

Try the method before buying

A fictional $8,000 complete project cost divided by an assumed $500 net annual saving gives 16 years simple payback. At an assumed $800 annual saving, it gives 10 years. The six-year difference comes only from the saving input; neither result predicts actual performance or equipment life.

Use the free HomeCostEngine calculators for individual quantities and the quote comparison calculator with complete matched scope. Retain the actual assessment and model assumptions.
