Advanced Energy Codes and Policy

Codes & Policy

Code and policies favoring high performance buildings are a critical tool in raising the bar for energy efficiency in new construction and deep energy retrofit projects.

Summary

Energy codes and policies continue to be a crucial lever in transforming markets for high performance buildings. New Buildings Institute (NBI) has been a national leader in commercial energy codes since it was founded in 1997–its original name was the New Codes Institute. A history of two decades of national and local leadership in advanced code and policy development now positions NBI as a blue ribbon resource.

NBI’s work in this program area includes strengthening model building energy codes and increasing use and usefulness. Most notably, NBI, along with partners, drove the significant stringency update in the 2012 edition of the International Energy Conservation Code (IECC)—the largest in IECC history—with a complete revision of Chapter 7. The new language is based on a codified version of NBI’s Core Performance Guide (now the New Construction Guide).  NBI has also worked to reconfigure codes for multifamily buildings, where regulation is currently divided between the residential and commercial energy codes. We have developed model code language that unifies requirements for all multifamily buildings to a single section of the code and is available for state and city adoption.

NBI works to develop the necessary thought leadership to overcome critical issues that are hindering code advancement and create the technical basis for progressive code and policy approaches on the path to zero energy codes.  We now support development of stretch codes for cities and states that are serious about reducing the energy use and carbon emissions from the built environment. Stretch codes are effective mechanisms for advancing building energy codes more quickly. These voluntary or required codes are a level of stringency above the base code and better reflect new advances in technology and design practices. They provide an opportunity to train the building and development communities in advanced practices before the underlying energy code is improved and help accelerate market acceptance and adoption. NBI also pursues the development of outcome-based codes and policies that measure actual energy performance of buildings.
