"The RESNET BPI group on LinkedIn is one of the best learning tools available to people in our industry,
largely because of David Butler. He's an HVAC genius and does a fantastic job moderating and contributing to that group. He has an amazing
source of knowledge in the field of building science, especially concerning mechanical systems"

"That Mr. Butler fellow knows what he is talking about. Not sure about that turpentine stuff he puts
on his pork though..."
Joe Lstiburek, Building Science Corporation
"David's knowledge and skills are the equivalent of a marriage between the ASHRAE Handbooks of
Fundamentals and Applications, held together with the logic of a seasoned economics professor from Wharton. Toss in Henry Kissinger's
touch on ambassadorship and you'll have a good picture of one of our industry's most respected individuals."

for some time. I'm continually amazed at his depth of knowledge in building science, especially HVAC. For those of you who think you
understand all the intricacies of the building environment, tune in to David's insightful, thought provoking and always articulate commentary
on a variety of technical topics you thought you already understood."

practical situations. This is what separates David from the rest. His unique gift for simplifying the complicated has helped me
understand a variety of complex building science principles."
