If you're a professional in today's fast-evolving industry of high performance construction and retrofits, then you've probably found yourself wondering a few things:

  • Who can show me how to run that test?

  • How do I get the most out of the equipment I own?

  • Why do the tests work, and how do I explain them?

  • What quality control methods should I use?

  • Which tools will make my job faster and easier?

With this guide, experienced and new pros alike will get step-by-step details on advanced testing, complete with:

  • Best practices, important concepts and pitfalls

  • How to present data to the client

  • Step-by-step photographs

  • Time-saving tips


Home Performance Diagnostics is a step-by-step, beautifully photographed technical manual for performing home performance testing. Author Corbett Lunsford has experience in hundreds of homes in different climate zones, and clearly recalls all the embarrassing mistakes he made in many of them, and so he's worked hard to make these complex diagnostics easy to master. More than 40 different test methods are demonstrated in clear detail, and with corresponding formulas and interpretations, in 3 mainsections: Envelope, HVAC, and Electrical, PLUS: an Introduction to systems thinking and the most efficient breakdown yet of building science fundamentals, and an Appendix demonstrating critical prerequisites to testing.

"Destined to be one of those 'foundational' works for our profession, like the Builder’s Guides from EEBA. You ought to own this book." ~Don Hynek, Home Energy Magazine

"So clear and direct. My own attempts to focus on testing have been cluttered by comparison." ~Jim Fitzgerald, Center for Energy and Environment

"...a clear and concise process for performing virtually every diagnostic test... I highly recommend that everyone in the building performance industry buy a copy and use it!" ~Brett Dillon, IBS Advisors, Chair of RESNET Technical Committee

"...provides the latest accredited diagnostic & testing procedures, while explaining and demonstrating with clear crisp photos and well written user friendly instructions." ~Joe Nagan, Home Building Technology Services

"With this colorful publication, Corbett explains both verbally and in color photos what it takes to solve the riddles of how the home functions as a system. This is set to become coveted both as a field manual for its content and a 'coffee table book' for the photo depictions." ~Mike Gorman, TechKnowledge

"Well written book. The testing procedures are explained and sequenced out with high quality photographs. The author is a tremendous teacher. You will not be disappointed at all. To put it another way- I have been researching many of the tests performed in the book on YouTube for some time. I have found many professionals have posted videos of their work on YouTube. They include great testing techniques but only film on jobs and therefore do not generally have much time. Explanation about what or why they filmed what they did are seldom. This author has videos of countless tests/discussions/Webinars posted on YouTube that put the topic into your thoughts as well as reality. Nothing but encouragement from the start. How many experts around are 1) qualified to write a book 2) willing to take time to teach and wants to see the reader reach the full height of their potential. Terrific use of your time.
