WHAT IS CARBONLESS BUILDER®
CarbonlessBuilder® is a private membership community for anyone who touches buildings.
Builders, Contractors, Designers, Homeowners, Anyone who has ever stood inside a wall and wondered why it failed.
It is not a software platform. It is not a franchise. It is not a certification mill.
It is a community built around one standard: A building that costs its occupants as little as possible to live in For as long as it stands. For every family that ever lives there.
That standard has a name: The CarbonlessBuilder® Standard. A minimum 50% reduction in utility payments compared to the average energy code in the USA and Canada. 450 metric tons of CO2 saved over 100 years per building. Operational and embodied carbon combined. Calculated before the first nail goes in.
We’ve made some changes to the Carbonless Builder® Membership to bring more value to our members:
We’ve reduced the cost from $995 to $495 - existing members will still get their promised 1 hour consulting session with Brian Iverson.
All members will now get access to a monthly 2-hour live Masterclass by Brian Iverson, built on the suggestions and needs of our community, followed by a 1-hour Q&A session, where all participants can benefit from the conversation and questions others in the community may have;
Members get the opportunity to learn and apply the Carbonless Builder® Standard through an extensive video library, the presentations, the questions and experiences of other members in the community, all with the benefit of Brian Iverson’s experience in creating the most cutting-edge solutions based on the unique challenges and obstacles seen by homebuilders today;
Access to additional pay-per-session private consulting with Brian Iverson (we do it this way because most initial questions can be answered by learning the Carbonless Builder® standard first, before requiring private consulting).

WHAT CARBONLESS BUILDER® BELIEVES
I believe a building does not have to fall down to fail.
I believe the envelope comes first. All six sides 100% thermally broken. Before anything else gets designed.
I believe most builders were never taught this. And that is not on them… That is on an industry that trained people to build fast and move on.
I believe physics does not care what country you live in What climate zone you are in, or what the code says the minimum is. Physics is the standard, not the codebook.
I believe affordable housing matters, but affordable living matters just as much. A home that costs $250 less per month to operate than the house next door is a raise for every family that ever lives in it.
I believe knowledge that came from failure is worth more than knowledge that came from a prompt. I have been inside the walls for 51 years. The failures in this library are real. The fixes work. I staked my reputation on every one of them.
I believe this work is generational, not just for the first owner… For every occupant. Every tenant. Every family. From now into eternity.
That is what CarbonlessBuilder® is. That is what we are building here.
CARBONLESS BUILDER® Private Membership — Members Only
This is not a course This is not a podcast This is not a YouTube channel.
This is the room where the real work happens.
-
If you build homes, you need this. If you renovate homes, you need this. If you design homes, you need this. If you buy homes, you need this. If you own a home right now and wonder why your utility bills never go down, you need this
Every decision made before the first stud goes up determines what a family pays for the next 100 years. Most people in the industry were never taught that. This is where that changes.
-
One 2-hour Masterclass monthly, with a 1-hour Q&A session where you can directly ask your questions to Brian Iverson and learn with other members of the Carbonless Builder® community: an unprecedented opportunity to join other homebuilders and contractors like you, solving many of the same problems alongside Brian in his live sessions.
Access to a private video library built from 51 years inside the walls.
Not theory. Not manufacturer talking points. Not AI-generated content.
Real jobsite failures. Real consequences. Real fixes.
Mold autopsies. Vapor assembly failures. Duct disasters. Slab failures. Roof assemblies that rotted from the inside out.
And the exact field-verified solutions that fix every one of them.
The library now features over 60 videos and counting. We’re adding more very single every single week. The goal is 1,000+ videos. One failure at a time. One fix at a time. Until every builder and homeowner in North America has the answer they need.
-
Real knowledge only surfaces when people feel safe.
A homeowner with mold does not want the world to know. A contractor with a failed assembly does not want liability created. A designer with a bad detail does not want their name on it publicly.
That is why this library is never indexed by search engines. Never available to AI systems. Never shared outside the membership.
No addresses. No identifiable photos. No content that could ever hurt the people who trusted us with it.
That protection is what makes it worth having. Without it the best knowledge never leaves the jobsite.
-
$495 one-time entry fee: Required initiation access fee to the full private library from day one.
$35 per month after that: Ongoing access as the library grows. Cancel anytime.
Both together is the full membership.
-
To get the most out of this membership you should have The Building Envelope Course ($199 at carbonless.org), or earn continuing education credits through EEBA Academy at eeba.org
The Wall Assembly Library is $299, including 700 verified assemblies from 60 manufacturers. Everything you need to run a proper Manual J before the hole is dug. You cannot size an HVAC system correctly without knowing your whole wall U-value first.
These are not upsells. They are prerequisites for doing the work right.
-
Submit it. I will build the video within reason and post it to the library. Every member is also a contributor. You bring your failures, your fixes and your open problems. We do not tear people down here. We fix buildings
