From Model to Meter: What Can We Learn from the Massachusetts LBER Data?
Starting in 2025, Massachusetts buildings over 20,000sf were required to report their annual energy consumption. Now, those data have been released to the public. We will provide an overview of the Large Building Energy Reporting (LBER) program and dive into what the data tell us. Building on prior studies presented at NESEA that highlighted the performance gap between modeled and actual energy use, we'll present a first-look analysis comparing high-performance models to LBER data and statistically identify key drivers (location, size, type) that influence real-world performance. We’ll also discuss the program's future and suggest areas for follow-up.
Session Chairs
Session Speakers
Summarize the goals and mechanisms of the LBER program.
Describe the typical range of the gap observed between modeled and actual energy consumption.
Describe key statistical trends indicated by the initial analysis of the Massachusetts LBER database.
Explain how the findings from this statistical analysis could inform and refine future energy modeling practices and building design goals in the Northeast.
