- Stretch Codes: Some municipalities may choose to adopt a more stringent energy code, or stretch code; in many cases the stretch code is the next iteration of the energy code (currently IECC 2021). The Northeast Energy Efficiency Partnerships (NEEP) has a number of resources for municipalities considering adopting a stretch code. For more information, visit NEEP and IECC 2021.
