Q: Do commercial kitchen hoods require HERS testing?
Kitchen exhaust testing is typically performed by an air balancing technician. It is not recommended to attempt this unless you have knowledge or direct assistance from a trained technician. National Comfort Institute (NCI) provides training for this type of work: https://www.nationalcomfortinstitute.com.
A HERS rater can perform this task, but it is not a HERS verification and there are no HERS documents for this type of work. However, there are Title 24, Part 6, nonresidential compliance documents required for compliance:
- NRCC-PRC-03-E Certificate of Compliance - Process Systems - Commercial Kitchen Requirements -or- NRCC-PRC-E - Certificate of Compliance - Process Systems (Dynamic Form)
- NRCI-PRC-01-E Certificate of Installation - Covered Processes
- NRCA-PRC-02 Certificate of Acceptance - Commercial Kitchen Exhaust System Acceptance
These forms are available through EnergyCode Ace: https://energycodeace.com/nonresidentialforms
A list of the requirements for acceptance testing is found on the NRCA form. Additional information is found in the Nonresidential Compliance Manual, Section 10.3, Energy Efficiency Standards, Section 140.9, and the Nonresidential Appendix NA7.11.
Type I exhaust hoods in commercial kitchens are typically smoke tested to verify smoke capture. The ducting is typically welded steel due to the high heat and fire risk associated with these systems. Certified Air Balance technicians have their own unique documentation process, in addition to Title 24, Part 6, and the Commercial Kitchen Hoods are often regulated by the County offices, but please verify with your local building department as to which authority has jurisdiction.
Attached are NR forms for your review and additional reference materials.
