Donald Wulfinghoff is an energy consultant who works in Maryland. In 2015, he published Super House, a 700-page book that explains how an ordinary person without architectural training can design a superinsulated home that (he claims) will use only 10% to 20% as much energy for heating and cooling as a conventional home.
The book is lavishly illustrated and comprehensive.

It certainly is.”
Even for readers who are put off by Wulfinghoff’s exaggerated energy savings predication or his architect-bashing, the book (at first glance) shows a lot of promise. Wulfinghoff is a big believer in superinsulation. Much of his advice aligns with recommendations from energy-efficiency researchers and experienced builders. For example:

Advice that’s just plain bad
So far, we’ve discussed Wulfinghoff’s good advice and his cranky opinions. There’s a third category of advice in the book, however: bad advice. Wulfinghoff’s advice is so often bad that his credibility evaporates as quickly as dew in Las Vegas:
