Readers are already cutting their bills.
The biggest surprise was how much we could do before buying any expensive equipment. We started with air sealing, attic work and a few heating improvements from Volume I. The house is noticeably more comfortable and our winter bills dropped without a major renovation.
I don't agree with every recommendation in the Future-Proof File, but the planning framework alone was worth it. We avoided a few renovation mistakes that would've been expensive to undo later.
The Cooling Code completely changed how we approached summer comfort. Adding exterior shading and improving airflow reduced how often the AC runs without making the house feel dark.
Most books tell you what to buy. These files spend more time explaining what not to buy and why. The decision sheets alone saved me from making a couple very expensive mistakes.
Some of the future technologies are probably still years away, but I appreciated that the book was honest about that. It helped me focus on upgrades I can actually use today.
What I liked most was how the six volumes fit together. We used the passive strategies first, then the renovation planning chapters, and finally built our long-term energy roadmap.

Everything you need to know before you order
Does the Complete Vault ($97) really include Volume I and Volume II?
Yes. The Complete Vault includes every page of The Heat Files and The Cooling Code, plus the bundle-exclusive Volume III — The Free Power Files. You never need to buy the volumes separately; everything is delivered together the moment you check out.
Do I get the newest version, including the latest chapters?
Yes. Every order includes the current edition automatically, and any future updates are sent to the same email address at no extra charge — you never pay twice for the same volume.
Do these methods actually work in my climate?
The books walk through results by climate zone rather than assuming one "typical" house. Each method notes where it performs best and where it needs adjustment, so you can judge fit for your specific region before you build anything.
How long until I see any difference in my bills?
It depends on which projects you start with and how much of your home relies on grid heating, cooling, or power today. The books are written so you can start with the smallest, fastest project first and judge results before committing to anything larger.
What if I'm a renter or live in an apartment?
Several methods — passive cooling with shade and airflow, small-scale solar setups, and insulation improvements — don't require permanent structural changes and are noted as such in the text. Larger projects like earth tunnels do require owning the land.
I'm in my 60s or 70s. Can I still do this?
Yes — the books are written step by step with no assumed background, and many projects can be done at a comfortable pace or with a hired contractor following the same instructions. Nothing requires heavy physical labor to plan or oversee.
What format are the books in, and how do I access them?
Every volume is a digital PDF you can read on a computer, tablet, or phone, or print at home. After checkout you'll get an email with your download link — no app or account required.
What's your refund policy?
Every purchase includes a 7-day money-back guarantee. If the material isn't a fit for your home, contact us within 7 days of purchase for a full refund, no questions asked.
