zEPI Jurisdictional Score

Low- and Zero-Energy, Standards

Cities and states adopt energy codes in a variety of ways and from a variety of sources, and according to a wide range of statutory requirements. However, a few general sources known as model codes serve as the foundation for most of the codes, with variations of the model codes frequently applied in individual jurisdictions. The purpose of calculating “zEPI Jurisdictional Scores” is to provide a stable scalar on which city and state energy code policies can be compared in their relation to Zero Net Energy. This document describes the methodology by which that zEPI scalar is applied for this purpose.
