Everybody asks the same question: how much extra does it cost to build a super energy-efficient and healthy home? It took a long time to get this figured out. Every house is different, but you have to start somewhere. Start here. It is free.
The first page is one page. Nine yellow boxes for your numbers. The green boxes give you the answers: the extra cost of materials for a better wall, what that adds to your mortgage each month, and what could be left over each month if your utility bill goes down.
Behind that first page, for builders and anyone who wants the details:
• A worked 40′ × 60′ barndominium example
• Every price in a yellow box, so you can use your local prices
• A wall built to code next to a Carbonless wall, line by line
• A shopping list you can print and take to the store
• Insulation choices and a spray foam calculator
• A Manual J list: what to gather so your heating and cooling can be sized right
Materials only. No labor. This is a learning tool, not a bid, an engineering report, an energy model, a code approval or a promise of savings.
Download your files within 24 hours of opening the link. Once downloaded, they’re yours to keep.
When you want to know why the numbers come out the way they do, here is where to go next:
• THE BOX — Complete Edition, $49. Three books in one. The first book to buy before you build, remodel or fix.
• Wall and Roof Assembly Library, $299. 867 verified whole-wall R-values, so you can compare walls before you pick one.
• The Super Energy-Efficient & Healthy Home Field Guide, $299 hardcover or $249 digital. Real walls being built, with photos.
• The NightMare, the Retrofit & Remodel Field Guide, $249 hardcover or $199 digital. For the house you already own.
• Super Energy-Efficient Building Audio Course, $99. Listen while you drive.
• Carbonless 2126, 78+ hours of continuing education. The first course is free.
• Carbonless Membership. The complete education, the Carbonless Roundtable and the Directory.
• Consulting with Brian, when you have a question about your own building.
