Regarding LEED BD&C EAc6: As the cost of renewable energy sources (PV, in particular) continues to drop, the number of projects able to pursue a site net zero energy goal will continue to increase. The final estimation of electricity consumption for EAc1, Optimize Energy Performance, includes the impact of renewable energy determined through EAc2, On-Site Renewable Energy. The credit language for EAc6 indicates that the annual electricity consumption is to be determined from the results of EAc1 or CBECS. Based on this language, it would appear that a net zero energy project would not need to purchase any renewable energy credits (i.e. green power) to achieve EAc6. If a project was 99% better than ASHRAE 90.1-2007 as determined for EAc1, the green power purchase required would be clear, albeit very small. EAc6 seems to conflict with facilities wanting to increase their energy performance to net zero. Please clarify this credit to support projects seeking net zero.
The applicant is asking whether EA Credit 6 - Green Power, and by extension, EAc6 exemplary performance, may be automatically awarded for projects that are designed to be net-zero in terms of average annual energy use without the purchase of green power or renewable energy credits.
Yes. If the project produces 100% or more of its electricity as on-site generated renewable electricity, as documented in EAc2 - On-site Renewable Energy, the project is eligible to earn EAc6 and one Innovation in Design point for Exemplary Performance in Green Power. However, for any project that is connected to the electric utility grid, the following requirements apply to ensure that the project meets the credit intent if the project does not achieve net-zero performance once built:
1. If a Green-e certified or equivalent utility program is available to the project in the project location, then the project team must provide a 2-year contract or Owner's letter of Commitment indicating that the project will commit to a 2-year enrollment period in the program for at least 35% of the provided electrical energy for EA Credit 6, or 70% of the provided electrical energy for Exemplary Performance in Green Power.
2. If a Green-e certified or equivalent utility program is not available to the project in the project location, then the project team must provide a letter of commitment signed by the Owner or Owner's representative confirming:
a. That a Green-e certified or equivalent utility program is not available to the project.
b. That the project will review the purchased annual energy consumption for the first two years of occupancy, and will commit to purchase RECs to offset 35% of the purchased electrical consumption for EA Credit 6, or 70% of the provided electrical consumption for Exemplary Performance in Green Power.
