    e-News #97: ZNE Case Studies Buildings

    Pacific Gas and Electric established a Zero Net Energy Pilot Program as a particular way to meet the goals of the 2008 California Energy Efficiency Strategic Plan. This EDR eNews features highlights from six early ZNE nonresidential projects that are described in greater detail in a full length monograph written by Edward Dean ...


  • Prop 39 ZNE School Retrofit Workshops
    October 9, 2015
    ZNE School Retrofit Workshops

    A zero net energy (ZNE) building generates as much energy as it consumes annually. With energy bills at California’s schools totaling more than $700 million a year, innovative energy solutions for schools like ZNE buildings are being proposed as a way to save energy and put money back into classrooms.

    To help schools achieve successful ZNE retrofits, we’re offering the following upcoming no-cost ZNE workshops...


  • Architecture At Zero 2015
    June 1, 2015
    Architecture At Zero

    The Architecture at Zero competition, now in its fifth year, is dedicated to furthering the knowledge-building and practice of Zero Net Energy building in California. By encouraging innovative design solutions to site-specific design challenges, the competition aims to broaden thinking about the technical and aesthetic possibilities of zero net energy projects. Further, it seeks to raise the profile of ZNE among built-environment professionals, students, and the general public in California and beyond.

    May 4 Webinar Prop 39 ZNE Schools Pilot

    May 4th Webinar Slide Deck for Interested Applicants. On May 4, 2015, the California Investor-Owned Utilities (IOUs) hosted a webinar for prospective participants in the Prop 39 Zero Net Energy (ZNE) pilot program.


  • Case Studies: Zero Net Energy Non-Residential Buildings
    April 16, 2015
    Case Studies: ZNE Non-Residential Buildings

    Six non-residential buildings were designed and built to perform at zero net energy (ZNE) consumption over the course of a year. Extensively monitored under the Pacific Gas & Electric Company's ZNE Pilot Program, each has proven to meet or exceed that level of performance for at least one year of post-construction occupancy.

    These case studies show that building industry leaders who target this new level of building performance can meet this challenge, reinforcing California's reputation for being the incubator and early adopter of transformative ideas with practical feasibility.


  • Phase I Screening Questionnaire: Prop 39 ZNE Schools Pilot

    Phase I Screening Questionnaire: Proposition 39 Zero Net Energy (ZNE) Pilot. This questionnaire must be completed by pilot program applicants.


  • CAHP Lighting Credit Fact Sheet
    March 10, 2015
    CAHP Lighting Credit Factsheet

    The California Advanced Homes Program (CAHP) scoring metric now allows participants to demonstrate improvement over the prescriptive lighting standards. The new high-efficacy lighting credit requires that all permanently installed lighting use high efficacy sources, such as LED or fluorescents, and no low efficacy sources such as incandescent or halogen.


  • e-News #96: Commissioning for Code Compliance
    January 13, 2015
    e-News #96: Commissioning

    Commissioning is an integral component of energy efficient building design, construction, and operation. The goal of commissioning is to ensure that the design and construction of building systems meets the owner’s needs, and that building equipment is functioning optimally during occupancy. The California Commissioning Collaborative defines commissioning as ...


  • Beyond Title 24 2013 Energy Standards - Residential
    December 12, 2014
    Beyond Title 24 2013 - Residential

    The statewide California Advanced Homes Program (CAHP) provides design assistance, quality control, and substantial financial incentives to builders that are ready to learn and demonstrate best practices in energy efficiency, green building and sustainability. 

    Single family and mulitfamily developers qualify for CAHP by demonstrating...


  • Beyond Title 24 2013 Energy Standards - NonResidential
    December 12, 2014
    Beyond Title 24 2013 - NonResidential

    The Savings By Design Program (SBD) provides design assistance and substantial financial incentives to owners and design teams that apply energy efficiency, green building and sustainability best practices to realize high performance nonresidential projects.

    Incentives of up to $150,000 are available to owners, plus up to $50,000 more for design teams that engage SBD assistance at the earliest stages of the design process.

    New construction, additions, and major rennovation projects all qualify...


  • e-News #95: Building Dashboards – Monitor, Measure, Manage
    November 25, 2014
    e-News #95: Building Dashboards

    Energy information systems (EIS) in buildings... have been around for years, starting as humble building automation systems and developing through the years into more robust energy management control systems providing whole-building energy use information.  The addition of visualization features – more commonly called dashboards – to EIS is growing in popularity because, much like an automobile’s dashboard, a great deal of information is conveyed quickly and easily.  Just as drivers can see how fast a car is traveling, check how much gas remains in the tank, or see an engine light when driving, building staff have the ability to review and evaluate building operations in real time.


  • Case Studies: Zero-Net Energy New Home - Ontairo
    October 6, 2014
    Case Studies: ZNE New Home - Ontario

    This Zero-Net Energy (ZNE) home – now built and occupied in Ontario, California – demonstrates to the Southern California homebuilder community that ZNE homes can be constructed using prevalent building practices and sold for a reasonable incremental cost.

    The main tasks of this project were to collaborate with a progressive expert homebuilder to design and construct a ZNE home based on mutually agreed upon technologies and practices, learning together to help overcome existing market barriers to ZNE homes.

    Some of the key findings of this project include ...

    e-News #94: Lighting Performance Advances

    New Sources & Controls... Through the past 20 years, new lighting technologies have been a major driver of increasing energy efficiency in buildings. Lighting specifiers and consumers have embraced CFLs, LEDs, and other highly efficient lighting options. How can even more efficiency savings be mined from the lighting end use?
