What does “high performance” actually mean when you stop talking about products and start measuring the completed building?
The Carbonless Builder® High-Performance Standard & Field Guide takes the Carbonless methodology to its practical limit: reduce the building’s energy demand first, then make the remaining load small enough for efficient mechanical systems, renewable generation and storage to handle realistically.
The governing rule is simple:
Waste less first. Make the power second.
This working draft translates that philosophy into measurable criteria for the entire six-sided building enclosure—from the earth beneath the slab to the roof above it—including thermal continuity, airtightness, water management, vapor and drying strategy, thermal bridging, windows and doors, ventilation, humidity control, mechanical integration, testing, commissioning and long-term documentation.
Inside, you’ll explore:
Whole-assembly performance rather than nominal insulation values
Continuous thermal, air, water, vapor and drainage control layers
High-performance slab, foundation, wall and roof assemblies
Thermal-bridge identification and reduction
A current working airtightness target of ≤ 0.50 ACH50
Climate-specific moisture and drying strategies
The Carbonless Lung drained and ventilated exterior cavity
Integrated ventilation, filtration and humidity management
Off-grid-capable energy and storage planning
Verification, commissioning and detailed field checklists
The Carbonless Building Passport
Return on Efficiency™ and lifecycle-cost analysis
Brian Iverson’s field tests, observations and lessons developed through decades of real-world building experience
This is not a product catalog. Manufacturers and materials will change. The Standard defines the job the building must perform.
You are purchasing the current August 2026 Working Draft at a reduced early-access price.
You’ll receive the draft immediately so you can begin studying and applying the methodology now. When the completed Carbonless Builder® High-Performance Standard & Field Guide is published, early-access purchasers will receive the completed edition at no additional charge.
The current performance criteria remain a working standard and are subject to continuing testing, engineering, whole-assembly calculations, hygrothermal analysis, research verification and final Carbonless approval.
The envelope is permanent. Equipment is temporary. Build the part that lasts accordingly.
Affordable Housing matters. Affordable Living matters more.
