Title 24 / HERS / ECC Service

Airflow & Fan Watt Draw

Airflow and fan performance measurements for projects where these verification measures are shown in the compliance documents.

What this verification covers

When is it required?

The answer comes from the project’s energy compliance documents and permit/code cycle. Not every project requires every HERS/ECC measure. Send the CF1R or available permit documents and we can identify the field verification scope before scheduling.

What to send us

  • Project address
  • CF1R / energy compliance documents
  • Permit year or code cycle, if known
  • HVAC equipment information and project status

What happens on site

  1. We review the available compliance documents and equipment information.
  2. The HVAC system is operated in the appropriate test mode and field measurements are taken.
  3. Project-specific requirements determine which measurements and documentation are needed.
