As of this writing, this new book about ultra-green prefab homes is #1 on Amazon in the Sustainable & Green Design and Energy Efficient Design categories of books. With Prefabulous + Almost Off the Grid, author Sheri Koones advances the green prefab movement with a discussion of 32 energy-efficient prefabricated homes using more than 200 photographs and sidebar detail of various construction elements.

This is Koones’ third book in the Prefabulous series. Publisher Abrams Books explains the concept of an “almost” off-the-grid home, as follows:

Taking energy from the grid when necessary and returning any excess energy produced, almost-off-the-grid homes function on a fraction of the energy required by most houses, and additionally are more comfortable, healthier, quieter inside, and far cheaper to operate. As energy costs continue to rise, the almost-off-the-grid house proves its worth.

You’re seen some of these homes, if you’re a reader of this site, or if you’ve browsed the prefab archives — for example, the red prefab on the cover is an ultra-efficient home in Belfast, Maine — but there’s some new material in the book, too. Buy all three on Amazon if you wish:
