Option 2. Energy Use Intensity Targets

For the 12-month reporting period, meet the site energy use intensity (EUI) or source EUI targets established for the project’s building type(s) and climate zone in Appendix II based on ASHRAE 100-2024 .

OR

Option 3. Performance Relative to Historical Baseline

For property types not eligible to receive an ENERGY STAR® score, compare the building’s total annual site and source energy consumption for the 12-month reporting period with historical baseline site and source energy consumption data from a 12-month reporting period with similar occupancy occurring within eight years before the end of the 12-month reporting period. Demonstrate at least an 8% reduction in either site energy use or source energy use beyond the historical baseline. Historical data may be normalized against the reporting period for weather or operational variables such as occupancy or production throughput.

High-process-load buildings that meet the following criteria demonstrate a 4% reduction in energy use for performance relative to the historical baseline.

• Building activity classification not referenced in Appendix II, Table 1, “Building Category Classifications,” or a project narrative demonstrates that the building function is directly linked to heightened energy usage compared to other buildings with the same building activity classification

• Energy use associated with manufacturing or industrial equipment, including equipment used for conveyance of people or objects, uncontrollable loads, life safety requirements, and/or security requirements, contributes at least 50% of the total energy consumption, meaning that at least 50% of the total building energy consumption cannot be modified using standard efficiency/retrofit measures, including:

o Envelope improvements

o Internal load reductions to lighting, ENERGY STAR®-eligible equipment, etc.

o HVAC or domestic hot water (DHW) efficiency upgrades

o Controls upgrades to HVAC, DHW, or lighting systems

REQUIREMENTS EXPLAINED

This prerequisite requires improved energy performance beyond benchmarks for comparable buildings or beyond past performance for project types with limited benchmarked data available. Projects must select an option that applies to their property type and project location per Table 1.
