Title 24 / HERS / ECC Service

Blower Door & Ventilation

Envelope leakage and residential ventilation verification when these measures are required by the project 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. Send the project address, CF1R and permit/code-cycle information.
  2. The building and ventilation equipment must be at the appropriate stage for the required test.
  3. We perform the applicable field measurements and document the verification results.
