The CxP for an equity, base building, or campus renewable project may be different than the project’s CxP. Documentation of previous commissioning of equity, base building, or campus renewable projects is acceptable, provided it complies with the requirements for EAp3: Fundamental Commissioning and EAc4: Enhanced Commissioning . For existing campus or equity systems that were not commissioned during the original system design and construction, re-commissioning of the system is required.

Tier 1 methods for demonstrating compliance To achieve points in Tier 1 on-site renewable energy systems, a project must either install the minimum rated capacity of on-site renewable energy as a function of project area or install qualifying renewable energy that will generate the specified percent of the tenant annual site energy. Projects may quickly calculate compliance using either method and apply the method that leads to greatest achievement of points.

Tier 1 minimum rated capacity method for demonstrating compliance The minimum rated capacity method is most appropriate for projects in multi-story buildings or projects with high process loads that are not capable of supplying a significant proportion of building site energy use through on-site renewable energy.

The area (A) used to calculate the minimum rated capacity is “the sum of the gross floor area of all the floors in the base building up to the three largest floors” proportionally allocated to the project.

This value refers to the base building and project dimensions, regardless of whether the renewable system is installed on the project site, on the campus, or on the site of a social impact project.

• For projects in buildings with 3 or fewer floors, A is equal to the total gross floor area of the project.

• For projects in multi-story buildings with equal floor plates across all floors, A is determined by Equation 1.

Equation 1.

[𝑓] [𝑓][ 𝑝] [𝑝] [𝑝][ 𝑎] [𝑎] [ × 𝑝] [𝑝] [𝑝] [𝑝][ 𝑎] [𝑎] 𝐴𝐴 = [3 × 𝑓]

𝑡 𝑡 𝑡 𝑔 𝑔 𝑔 𝑎 𝑎 𝑜 𝑏 𝑏 𝑏 𝑏 𝑏 𝑏

𝑡 𝑡 𝑡 𝑔 𝑔 𝑔 𝑎 𝑎 𝑜 𝑏 𝑏 𝑏 𝑏 𝑏 𝑏

For all other projects, A is determined by identifying the three largest floors in the building and summing the area for these three floors, then multiplying by the ratio of project area and total gross area of the building.
