o Meters for shared building systems serving tenants (i.e., chiller plant, boiler plant,

central water heating, shared VAV air handling units, and dedicated outside air handling units).

Annual base building site energy use is equal to the total annual site energy consumption from base building energy meters when this comprises more than 25% of estimated total annual site energy use.

Otherwise, the base building site energy use is 25% of total annual site energy use.

Option 2. Renewable Energy Readiness

For projects where financial and leasing considerations preclude large on-site renewable energy installations within the Core and Shell scope of work, Option 2 incentivizes developers to incorporate renewable energy readiness features into the project design to enable future on-site renewable energy installation by tenants.

Projects must design for solar readiness in accordance with the Solar readiness credit criteria or a similar standard, or document equivalent on-site renewable readiness for another qualifying renewable energy source such as wind energy or solar thermal energy.

Tenant guidelines must integrate guidance on how tenants can use this available infrastructure to apply on-site renewables to their project.

SOLAR READINESS

A design for solar readiness must include one or more solar zones, and address mounting considerations, interconnection pathways, and electrical capacity per the detailed criteria in the credit requirements.

Solar zones Solar zones set aside designated spaces to house future solar energy generation equipment and provide the necessary structural support to accommodate the equipment. The design team must perform a wind and load analysis to inform the solar zone design and design the roof or other supporting structure with the structural integrity to accommodate the solar installation. The solar zone should avoid shaded areas or obstructions from other equipment, maximizing the potential for solar collection.

Mounting considerations The solar zone must be designed to accommodate all panel-mounting options identified in the tenant guidelines. For roof-penetrating mounts, it may be necessary to install these mounts within the Core and Shell scope of work to ensure the future integrity of the roofing system.
