EcoSmart Stud 
Big Builders Say Buyers Don’t Care About Efficiency. The Data Says Otherwise.
Every year, the RESNET Building Performance Conference brings together the people who actually measure, model, and verify how homes perform — HERS raters, energy consultants, building scientists, and code officials. This year in San Antonio, I had the privilege of attending as part of the Advanced Bio-Based Home Building training session. What I saw confirmed everything we’ve been building toward at EcoSmart® Studs — and exposed a fault line running straight through the heart of the home building industry.
One Stud Manufacturer. Eighteen Bio-Based Innovators. One Obvious Gap.
The Advanced Bio-Based Home Building training showcased 18 manufacturers bringing renewable, low-carbon materials to residential construction — from insulation and panels to structural components. EcoSmart® Studs was the only wall stud manufacturer in the group.
That distinction matters. Most bio-based products in the market occupy specialty niches — add-on layers, alternative assemblies, or system-level solutions that require a builder to change how they build. EcoSmart® Studs is different: it’s a direct, one-for-one replacement for the standard exterior wall stud. Same installation. Same framing crews. Same tools. No retraining, no process overhaul.
Why a Stud Belongs in a Bio-Based Home Conversation
Here’s the building science principle that put us in the room: what fills the stud cavity determines the embodied carbon profile of the entire wall assembly.
The EcoSmart® Stud’s patented hollow-core, double-stud geometry creates a designed cavity — an intentional insulation chamber engineered into the stud itself. When that chamber is filled with bio-based insulation (dense-pack cellulose, hemp, or similar materials), you’ve dramatically reduced the embodied carbon of the most carbon-intensive part of a wood-framed wall: the stud bays.
This means EcoSmart® Studs doesn’t just reduce operational energy use through thermal break performance. It serves as the platform for a fully bio-based wall assembly, one where the structural framing, insulation, and carbon accounting all work together.
The Fault Line: What Large Builders Said vs. What the Data Shows
The most striking moment of the 2026 RESNET Conference wasn’t in a training session. It was in the gap between two very different narratives playing out in the same building.
Representatives from several large national home builders made a clear statement: buyers don’t care about high-performance homes. Energy efficiency doesn’t move the needle at the point of sale. The market isn’t asking for it.
Meanwhile, in session after session, RESNET instructors and building science professionals were presenting research, data, and real-world case studies that told the exact opposite story.
The data — from HERS ratings, utility comparisons, appraisal studies, and buyer surveys — consistently shows that homeowners who live in high-performance homes report higher satisfaction, lower total cost of ownership, and greater comfort. The resale premium for HERS-rated homes is documented. The mortgage qualification advantage under energy-efficient lending programs is real.
So, Which Is It?
The answer may be simpler than it seems: it depends on when you ask the questions. Buyers don’t ask for “high-performance homes” because, when they are looking to buy a new home, most have never lived in one. They don’t know what they’re missing. They can’t articulate a demand for something they’ve never experienced. But when researchers ask the right questions after they have lived in that new home for a while about utility bills, comfort, resale value, and air quality, the preference for high-performance features is unmistakable.
What This Means for the Industry — and for Builders Who Choose Differently
The RESNET community exists precisely because someone has to verify the gap between claims and reality. HERS raters don’t take a builder’s word for it — they measure. And what those measurements consistently show is that performance-built homes deliver what conventional homes promise.
For builders in Minnesota and across Climate Zones 6 and 7, the stakes are even higher. Thermal bridging through conventional framing accounts for a significant fraction of whole-wall heat loss. EcoSmart® Studs reduces that bridging at the framing level – without adding a continuous insulation layer, without changing the wall thickness, and without retraining your crew.
The builders who are paying attention — the ones in the RESNET sessions, not just the trade floor — understand that the market is shifting. Energy codes are tightening. Utility incentives are expanding. Buyers are becoming more literate about monthly operating costs. The window to build with high-performance framing before it’s code-required is narrowing.
The Bottom Line from San Antonio
Walking away from the 2026 RESNET Conference, I’m more convinced than ever that the building performance industry has the data, the tools, and the products to transform residential construction. EcoSmart® Studs, the only wall stud manufacturer in the Advanced Bio-Based Home training, isn’t a coincidence — it’s a reflection of where the market is headed and where conventional framing falls short.
The national builders who say buyers don’t care? They’re building to yesterday’s standard.
The builders who showed up in San Antonio to learn? They’re building for tomorrow’s buyer.
