Report

Purpose and Procedure for Drafting the Document

What Is an Air Exchange Verification Report?

An air exchange verification report documents measurements of CO2 concentration, airflow rate, and calculated air changes per hour to confirm that a ventilation system meets design or regulatory requirements.

Why Use This Template?

This online template provides a structured format for recording measurement data and determining compliance. It includes fields for multiple measurement points and digital signatures.

Who Uses It?

HVAC technicians, indoor air quality specialists, facility managers, and compliance officers use this report for verification testing and documentation.

Compliance with Ventilation Standards

Building codes and standards often require minimum air exchange rates. This report documents compliance.

Indoor Air Quality Investigations

When occupants report stuffiness or health symptoms, this report measures ventilation effectiveness.

Post-Renovation Verification

After building renovations, this report confirms that ventilation systems still provide adequate air exchange.

Energy Efficiency Audits

Over-ventilation wastes energy. This report helps identify areas where airflow can be reduced without compromising air quality.

Commissioning New Systems

New ventilation systems are tested to verify they meet design air exchange rates before acceptance.

Periodic System Performance Checks

Regular verification ensures that ventilation systems continue to perform as designed over time.

  1. 1

    Open the Template

    Open the air exchange verification template in the online editor and enter report metadata such as test date, report number, technician, and location.

  2. 2

    Record Measurements

    For each measurement point, enter the point name, CO2 level, airflow rate, and calculated air changes per hour.

  3. 3

    Determine Compliance

    Based on the measurements, select whether the system is compliant or non-compliant and add remarks.

  4. 4

    Sign and Export

    The technician and facility manager sign digitally. Export the report as a PDF.

Frequently Asked Questions about Photo Reports and Photo Tables

What measurements are required?

The template requires CO2 level (ppm), airflow rate (m³/h), and calculated air changes per hour (ACH) for each measurement point.

How is air changes per hour calculated?

ACH is typically calculated from airflow rate and room volume. The template does not perform the calculation automatically; you enter the value.

Can I add multiple measurement points?

Yes, the measurements section is repeatable, allowing you to record data for multiple points in a single report.

What does 'compliant' mean?

Compliance is based on whether the measured air exchange meets the design specification or applicable standard. The inspector determines this.

Who signs the report?

The HVAC technician and the facility manager sign the report to confirm the results.
