A formula will generate the project's calculated Net pEUI. Click here for the formulas the DDx uses to calculate this.
Within the options of fuel source reporting there are two options for offsite renewables. Please be sure to allocate the types of renewables appropriately.
Dedicated off-site renewables count equally to on-site renewables and are included in your net pEUI calculation. Dedicated off-site renewables include:
- Direct Ownership
- Green Retail Tariffs
- Power Purchase Agreements (PPAs)
- Community Renewables
- Utility Renewable Contracts
Purchased off-site renewables:
Unbundled RECs do not count towards offsite renewable contributions and are not included in your net pEUI calculation.
For expanded definitions please reference IECC 2021 Appendix CC Zero Energy Commercial Building Provisions CC103.3 Off-site renewable energy.
