ASHRAE guidance
ASHRAE publishes the performance references HVAC work is judged against once it is running — ventilation rates, comfort conditions and the maintenance practices that hold a system near design over its life.
Adoption varies by jurisdiction — confirm the edition your authority having jurisdiction enforces before you run a walk against it.
What it covers
- Outdoor air and ventilation rates
- Thermal comfort criteria
- System performance verification
- Maintenance practice for HVAC equipment
What the evidence looks like
- Measured airflow and temperature split photographed at the instrument.
- Filter condition captured as found and as replaced.
- Economizer and damper position shown, with the controller reading in frame.

- What does ASHRAE guidance cover?
- Outdoor air and ventilation rates; Thermal comfort criteria; System performance verification; Maintenance practice for HVAC equipment.
- What does a field inspection against ASHRAE guidance look at?
- Measured airflow and temperature split photographed at the instrument. Filter condition captured as found and as replaced. Economizer and damper position shown, with the controller reading in frame.
- Which edition of ASHRAE guidance applies to my project?
- Adoption varies by jurisdiction — confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Which checklists verify work against ASHRAE guidance?
- 6 free checklists in the RTI library reference this family — each listed on this page with the photo evidence every item needs before it can be submitted.
A standard is only met if the evidence exists
RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
