New for 2022, East Hampton and Southampton towns have adopted a version of NYSERDA’s NYStretch code. This new code has significant changes to building size thresholds and shell UA requirements along with changes in how the energy index is calculated.  This program will discuss specific requirements of the 2020 NYStretch along with the specific requirements for each of the towns that have adopted it. It will provide an in-depth evaluation of methods, materials, and best practices for meeting the ERI index requirements of the various municipalities. An emphasis will be placed on finding cost effective solutions and minimizing the effect of these upgrades on building function and aesthetics.
