Affordable Zero Net Energy Webinars
These informational webinars were part of a California Energy Commission and SoCal Gas RD&D and Energy Efficiency Programs-funded project “Affordable Zero Net Energy (ZNE) Homes.” The two-part webinar series provided brief introductions to the fundamentals of and approaches to ZNE Homes. Further, the webinars described the development and monitored performance of two affordable ZNE homes in Stockton, CA using integrated energy efficiency measures, such as advanced framing methods, right-sized HVAC systems and on-site renewable energy. The two ZNE homes were a compare-and-contrast exercise looking at all-electric vs. mixed-fuel systems.
A ZNE best-practices book was written as part of this project. The book is intended for builder-developers, their purchasing agents, project managers and their major subcontractors. It is also written to assist and inform the support team: architects, engineers, HVAC designer-installers and energy raters. The text assumes the reader is an experienced professional in a position of authority who intends to design, build and market successful zero net energy houses at a sustainable profit.
The houses at Dream Creek were built at very modest cost, and mostly with unskilled volunteer labor. As a result, the designs have been simplified and cost-optimized to the last possible penny, so that ZNE could be reliably achieved at equal or lower costs than past practices. The authors believe that by applying the approaches outlined in this book, profitable market-rate ZNE can be a reality without the often-assumed complexity, waste and cost.
The print version of Real-World ZNE Homes for California - January 2021 can be purchased on Amazon. A free PDF version of the eBook can be downloaded above.

PAST WEBINARS — November 2020
Affordable Zero Net Energy Design and Construction Training Webinars
Our team presented best practices for designing and building highly efficient and economical zero net energy homes. The classes were developed as part of GTI Energy’s Affordable Zero Net Energy (ZNE) home project, a collaboration with Habitat for Humanity of San Joaquin County. The project is sponsored by the California Energy Commission (CEC) and the Southern California Gas Company.
- Designing to Get to ZNE Within Your Budget
- High Performance Building Enclosures
- High Performance HVAC for Affordable Zero-Net-Energy Homes
Webinar goals were to:
- Become knowledgeable about the means of achieving ZNE affordably
- Acquire methods and tools to develop high performance projects rather than business-as-usual
- Learn specific innovations one central-California builder has used to achieve ZNE at costs less than business-as-usual
- Be able to compare a mixed-fuel approach to ZNE with an all-electric approach, objectively assessing the pros and cons of each
