The 20% Stretch Code: A New Energy Standard for Cities and States

Presentation Watch Now

To help local jurisdictions advance on energy and climate action goals, New Buildings Institute (NBI) has developed a new model stretch code that targets 20% better efficiency than the ASHRAE 90.1-2013 national model energy code. The new 20% Stretch Code offers jurisdictions a set of energy-saving building strategies that cover design aspects such as envelope, mechanical, water heating, lighting and plug loads.

Stretch codes are emerging as a critical lever for cities and states to maximize energy savings in both commercial and residential projects over the course of several code development cycles allowing the market to prepare and gain experience with new efficiency practices and technologies.
