Three new Zero Net Energy Technology Application Guides, developed for California but widely transferable, provide information on readily available leading-edge technologies found in today’s ZNE buildings. They describe the technology, its features and benefits, and illustrate energy performance from both modeled and measured results. There are project application examples, overviews on costs and trends and a list of related resources. These featured technologies were selected through a group of architect and engineering advisors experienced in ultra-low and zero energy design. The three guides are:

The California Public Utility Commission (CPUC) is working with NBI to offer workshops about zero net energy (ZNE). On November 3, a workshop was held for local government representatives then on November 4 for schools. Participants learned about ZNE leadership and market trends in California. They also received customized tools and knowledge necessary to implement policies, programs or projects with ZNE performance goals. Materials and presentations are now available. Read materials for Local Governments and Schools.

2015 IgCC gives cities and states something to be thankful for

Jim Edelson's picture

As we move toward Thanksgiving this Thursday, the recent adoption of the 2015 International Green Construction Code (IgCC) gives cities and states a lot to be thankful for. Four critical proposals that will drive significant improvements in building energy performance were approved when final voting on the model energy code closed earlier this month. These proposals provide critical tools for jurisdictions looking at improved building efficiency as one of the opportunities to meet energy goals. Read more »
