“RESNET members are now touching about a third of all new single-family homes. That’s a big number — and it’s only growing.”

-Ryan Meres

In this episode of RESTalk, host Bill Spohn welcomes back Ryan Meres, Programs Director at RESNET®, to explore the key insights from the 2025 HERS® Rated Homes Data Trends Report. This sixth annual edition reveals both expected and surprising patterns in how homebuilders, energy raters, and policymakers are driving efficiency across the U.S. housing market. With over 436,000 homes HERS rated in the past year, the report reflects RESNET®’s growing impact — now touching a third of all new single-family homes and a rising share of multifamily projects.

Ryan breaks down regional standouts: Massachusetts leads with 88% of new homes HERS rated due to its Green Communities program, while Texas tops the volume charts with 113,000 ratings. Notably, California showed the most improvement in HERS scores since 2013, driven in part by its solar mandate. Meanwhile, the report tracks construction practices, including the dominance of slab-on-grade foundations and the increasing prevalence of ductwork in conditioned spaces.

Other notable topics include the growing adoption of heat pumps (especially in the Southeast), a dramatic increase in homes achieving

"As homes get tighter, ventilation isn't optional—it's essential."

— Patrick Nielsen  

In this episode of RESTalk, host Bill Spohn sits down with Patrick Nielsen, Global Technical Products Manager at Broan-NuTone, to discuss the evolving world of home ventilation. With over two decades of experience, Patrick walks us through the major drivers shaping residential ventilation practices today—from tighter building envelopes to the growing emphasis on indoor air quality and energy efficiency.

Patrick explains the importance of dwelling unit ventilation (DUV), spot vs. whole-house strategies, and the increasing role of energy recovery ventilators (ERVs) as builders and raters seek practical ways to meet stringent codes and achieve better HERS scores. He also touches on upcoming developments like capture efficiency standards for range hoods, automated balancing features in modern ERVs, and the implications of makeup air requirements. Whether you’re a builder, rater, or HVAC pro, this episode is packed with actionable insights for navigating the ventilation challenges in today’s high-performance homes.

Without continual growth and progress, such words as improvement, achievement, and success have no meaning.

– Benjamin Franklin

In this episode of RESTalk, Bill Spohn speaks with three guests to discuss the RESNET® QA app, an innovative tool designed to streamline the quality assurance process for home energy ratings. Bill is joined by Billy Giblin, RESNET®’s quality assurance field specialist, Kelvin Abong and Kiro Bondarev from The Fourth Dimension (4D), RESNET®'s technology partner. Together, they explore the app’s journey from ideation to execution, its role in harmonizing quality assurance efforts, and the benefits it brings to users.

 

Billy provides insight into the app's development, explaining how it shifts the industry from inconsistent spreadsheet-based reviews to a more transparent, data-driven approach. Kelvin discusses 4D's collaborative efforts to design a user-friendly app and highlights future improvements based on user feedback. Kiro offers technical details describing the app's ability to integrate with external QA tools via an API, ensuring flexibility for providers.

 

The conversation touches on the importance of industry adoption, the app’s intuitive design, and its positive impact. The episode includes exciting news about upcoming features, including cloud syncing and expanded integration with Energy Star.

Knowledge is of no value unless you put it into practice.

Anton Chekhov

 

In this episode of the RESTalk podcast, host Bill Spohn talks with Mark Johnson from the International Code Council (ICC) and Steve Baden from RESNET® about a new collaboration to enhance energy code compliance. They discuss the growing complexities of energy codes, particularly the challenge of ensuring compliance amid increasing technical and regulatory demands. To address this, ICC and RESNET® are introducing a program to involve HERS raters as third-party verifiers, providing quality assurance and supporting local code officials, especially where resources are limited.

 

The conversation delves into the origins and development of this program, which has been over a decade in the making. Steve and Mark describe their journey, starting with joint training initiatives and establishing standards such as the Energy Rating Index (ERI). The latest effort includes certification of RESNET® HERS® raters to act as recognized compliance specialists under the International Energy Conservation Code (IECC). This certification ensures that raters understand building science and are well-versed in energy code requirements, enhancing credibility with code officials.

 

Mark and Steve emphasize the need for collaboration and transparency in implementing these new compliance measures. They highlight that this partnership helps jurisdictions struggling with limited code enforcement capacity and provides career growth opportunities for HERS raters. The program aims to be fully launched by the end of 2025, with both guests encouraging raters to obtain their certifications soon to position themselves at the forefront of this compliance evolution.
