changed my approach from being
“widget” based approach to one
that’s more comprehensive

What Happens to Programs When State and Local Energy Code Increases?
• IOU Program administrators could receive credit for some energy savings from code
• Program administrator in an excellent position to support with training
• NBI committed to developing the next generation approach – IgCC, 2015 IECC, 2013 Mass. Stretch – so program continues with advancement in codes
![Page 30: Next Practice in New Construction Efficiencynewbuildings.org/sites/default/files/New_Construction_Initiative.pdf · –DOE RTU Challenge •Task/Ambient Lighting –Design for Off,](https://reader034.vdocuments.mx/reader034/viewer/2022050206/5f5988b0a651f00ad74acd5f/html5/thumbnails/30.jpg)
Utility Support to Implement Reach Codes and Programs
• Technical assistance, participate in energy committees • Trainings, education (sharing resources with state, including
Estar) • 3rd party inspections support for compliance (HERS for
residential and develop new ‘reach code inspectors’ for commercial)
• Involvement in development of next round of reach codes • Incentives to projects for meeting reach codes till they become the
baseline code (program design parameters) • Issues with attribution – determined locally with national guidance
and support – NBI papers and EM&V Forum
