DC BEPS Explainer: What Is Site EUI Adjusted To Current Year?

Introduction

With the evaluation year of the DC Building Energy Performance Standards (BEPS) cycle starting January 1, 2026, properties that are taking action to meet the BEPS need to understand the pathway metrics that DC’s Department of Energy and Environment (DOEE) will use in their evaluation.

We covered ENERGY STAR ratings, which are used for the Standard Target Pathway, in two pieces focused on 2023 benchmarking results and the BEPS year-over-year thresholds. In this piece, we’ll be discussing Site Energy Use Intensity (EUI) and related metrics, including Weather-Normalized Site EUI and Site EUI–Adjusted to Current Year, also known as Adjusted Site EUI in DOEE’s BEPS Compliance and Enforcement Guidebook. This piece will use Adjusted Site EUI to align with DOEE terminology.

Site EUI-related metrics are used by DOEE on the Performance Pathway and most Alternative Compliance Pathways. Buildings on the Performance Pathway are required to demonstrate 20% energy use reduction during the evaluation year at the end of the Compliance Cycle compared to the baseline years at the start of the Compliance Cycle, based on the appropriate metric for your building type as described below. Alternative Compliance Pathways requirements are determined by DOEE in conversation with building owners and representatives.
