CalBEM Prototype EUI Viewer | Free Title 24 Tools

EnergyPlus batch results — end-use energy intensity by building prototype across California's 16 CEC climate zones (each shown with its representative weather-station city). Data generated 2026-05-16 (EnergyPlus 23.1). Models simulated by A2 Efficiency using the CalBEM new-construction prototypes with climate-zone-specific TMYx weather files.

A note on vintage: these are estimates of energy use for a standard prototype building built to the 2025 Title 24 code cycle — the vintage tag T24-2025-NC means new construction under the standards effective for the 2025 cycle. The original datasets in the CalBEM-Prototypes GitHub repo also include older vintage bins not shown in this viewer: Pre-1978 (V1), 1978–1997 (V2), 1998–2007 (V3), and 2008–2018 (V4).

Weather files used (Nonresidential prototypes — TMYx.2011-2025)

Each California climate zone was simulated with the TMYx.2011-2025 EPW file for its representative airport weather station, sourced from climate.onebuilding.org.
