I couldn’t put the book down that night. It kept referencing the Canadian Building Digests. I read them too. The one guy, N. B. Hutcheon was some real smart guy. He headed the Division of Building Research of the National Research Council of Canada. The guy I wanted to punch out, G. O. Handegord was also real smart and from the same place. What was a guy like Handegord doing at a Home Builders Association meeting? I couldn’t believe I almost punched him out. They sure knew walls. Roofs, too. Windows. Airtightness. Energy. Everything. I had a mechanical engineering degree and I thought I knew stuff but I knew none of this. But I could understand the language. I read and learned. The buildings I was going to build and design forever changed that night. It pays to go to Home Builders Association meetings. Really.
