and/or electricity use associated with the district heating system, whereas only renewable fuel may be applied to fuel used on the project site.

DES Site energy adjustments are not applicable to projects modeled using ASHRAE Standard 90.1-2022, Addendum a . Projects applying Addendum a should use submetering to distinguish fuel used onsite from the modeled fuel used for the district hot water plant.

REQUIREMENTS EXPLAINED: CORE AND SHELL

Core and Shell options afford enhanced flexibility for developers to implement renewable energy supply, procurement, and/or readiness strategies. Projects may achieve all four available points through Option 1. Renewable Energy Supply or Procurement or one point for Option 2. Renewable Energy Readiness and up to three points under Option 1.

Option 1. Renewable Energy Supply or Procurement (Core and Shell)

Core and Shell projects may choose to supply or procure renewable energy from Tier 1 or Tier 2 for a maximum of four points, from Tier 3 for a maximum of two points, or from any combination of Tier 1, Tier 2, and Tier 3 renewable energy for a maximum of two points.

The Tier 1 Minimum Rated Capacity Method for Demonstrating Compliance is identical for New Construction and Core and Shell, with no differences in the required thresholds.

By contrast, for Core and Shell , the percentage of annual site energy is calculated using the base building site energy rather than the total building site energy referenced in New Construction, more closely aligning the required percent procurement with the core and shell scope of work.

Annual base building site energy determination (for Tier 1, Tier 2, and Tier 3) To calculate the annual base building site energy use:

• Perform the total annual site energy determination described above. Include all building energy consumption inclusive of base building energy use tenant use.

• Estimate the total annual site energy consumption from base building energy meters, including:

o Meters for equipment fully contained within the project scope of work, such as

elevators, parking garage lighting and ventilation, site lighting, common area lighting, common area HVAC, and common area receptacles and process equipment.
