• ENERGY STAR® Portfolio Manager (ESPM) Technical Reference on Climate and Weather provides guidance on weather normalization that can be applied to some building types that are ineligible for an ENERGY STAR® score. [66]

SOURCE ENERGY

Based on the annual site energy use reported for each energy source, the same source energy conversion factors (SEF) are used to determine source energy use for the current reporting period and for the historical baseline. Refer to additional guidance below on Source Energy Conversion Factors for Options 2 and 3.

HIGH PROCESS LOAD BUILDINGS

Projects with high process loads often have further difficulty improving energy consumption beyond a historical baseline, since these loads cannot be modified using standard efficiency measures. To make prerequisite achievement feasible for property types that do not have benchmark comparisons available through ESPM or ASHRAE 100, demonstrate at least a 4% reduction in site energy use or source energy use.

Eligibility to apply this lower 4% threshold requires both of the following:

• Property type not benchmarked . The project’s building type must be different than the ASRHAE 100-2024 building activities, listed in Appendix II. Alternatively, the project team may provide a narrative demonstrating that the building function is directly linked to heightened energy usage compared to other buildings with the same ASHRAE 100 building activity classification.

• Process energy 50% or above . At least 50% of the project’s annual energy use must be from plug and process energy. Include the following in the determination of this total:

o Receptacle equipment

o Cooking equipment

o Refrigeration equipment

o People conveyance equipment, including elevators, escalators, or moving walkways

o Object conveyance equipment, including conveyor belts or baggage handling

equipment

o Process heating or process cooling (e.g., for manufacturing processes)
