|Outcome-Based Pathways for Achieving Energy Performance Goals|
Between their design and operation, buildings are responsible for 40 percent of the nation's total primary energy use. Policymakers recognize that addressing building sector energy use is essential to achieving overall energy-use reductions. However, current energy codes and standards focus on building design while largely ignoring building operations' where most of the energy is being used. These current, purely design-focused strategies do not provide the measurable and verifiable results policymakers are looking for. Further, members of the building industry, from designers to product manufacturers to building owners, are looking for flexibility in methods for achieving energy efficiency goals.
The National Institute of Building Sciences has sponsored this project on outcome-based pathways and produced a resource page on the WBDG-Whole Building Design Guide® "Outcome-Based Pathways for Achieving Energy Performance Goals" and two webinars below:
Introduction to Outcome-Based Pathways for Achieving Energy Performance Goals
This webinar will introduce an emerging concept—outcome-based pathways—to achieve efficient energy use, while addressing the needs and challenges of numerous stakeholders in the building industry.

IECC Proposed Outcome-Based
Across the United States and internationally, communities are increasingly interested in achieving energy use reduction targets. The challenge is that, as currently written, energy codes do not provide an effective means of assuring achievement of such goals. Current building energy codes do not consider how buildings actually perform—they only prescribe criteria on how buildings are to be designed and constructed. These purely design-focused strategies do not provide the measurable and verifiable results policymakers are looking for. Further, members of the building industry, from designers to product manufacturers to building owners, are looking for flexibility in methods for achieving energy-efficiency goals.
The Institute has led an effort to incorporate an "Outcome-Based Compliance Pathway" in the 2018 International Energy Conservation Code. The proposal (CE-37) was heard by the IECC Committee earlier this in 2016. Based on feedback from the Committee, the Institute submitted a public comment to provide the Pathway as an Appendix in the IECC to give communities interested in such an approach a methodology to follow. The public comment will be heard at the Public Comment Hearings October 19-25 in Kansas City, Missouri, and then voted on through ICC’s cdpAccess. The proposal builds on an approach incorporated into the 2015 International Green Construction Code (IgCC).
The webinar provided an overview of this new energy performance approach.
