End-Use Load Research Commercial Energy Metering Study – Final Report

NEEA and its partners launched the End‑Use Load Research (EULR) project, which collected high‑frequency energy use data from residential and commercial buildings, including the Commercial Energy Metering Study (CEMS) focused on key HVAC end uses in office and retail buildings. This report summarizes the breadth of data collected through the CEMS and was prepared by DNV. From the first meter installations in November 2019 through the end of data collection in June 2025, CEMS captured more than 3.1 billion data points. These measurements include readings of electrical circuit power, as well as space and supply temperature data, collected from 70 commercial office and retail buildings.

The study provides detailed, weather normalized load profiles for efficient rooftop units, heat pumps, and electric resistance heat, offering essential insights for a range of energy efficiency programs and utility planning needs including forecasting, energy efficiency planning, load management, cost-effectiveness testing, and integrated resource planning.
