Air Quality Data Reporting & Maintenance for LEED v5 Compliance

Written by Sam Allsbrook | Jan 28, 2026 9:10:20 PM

To maximize points for indoor air quality (IAQ) monitoring in LEED v5, projects must maintain compliance with the required data submission and sensor maintenance protocols. This ensures air quality data remains credible year after year.

What Is the IAQ Data Reporting Frequency for LEED v5?

Collecting data is only the first step; reporting it correctly is what ensures projects earn maximum points. LEED v5 establishes minimum data collection frequencies to prevent selective or incomplete reporting.

  • Carbon Dioxide (CO2): Data points must be logged at least every 15 minutes. CO2 levels change rapidly with occupancy, making higher-frequency data essential.
  • PM2.5 & TVOC: Data points must be logged at least every hour.

This high frequency ensures that projects capture a 360º picture of their air quality performance, rather than just a daily average that can “hide” pollutant spikes.

What Are the Maintenance and Calibration Requirements for IAQ Monitors in LEED v5?

Hardware maintenance is often the most overlooked part of IAQ monitoring. Sensors naturally drift over time and can lose sensitivity and accuracy as a result. 

Regular Calibrations

Sensor calibrations are critical to minimizing drift and maintaining data accuracy. LEED v5 requires that projects follow the manufacturer's schedule for sensor recalibration. If a sensor is out of date, the data it collects may be deemed invalid for certification.

The Modular Advantage

Traditional recalibration often requires removing devices from the wall and shipping them back to the manufacturer, creating data gaps and increasing operational costs.

By selecting monitors with modular sensor designs, like Kaiterra’s, projects can hot-swap old sensors with new, pre-calibrated modules. This approach minimizes downtime, maintains continuous data collection, and supports uninterrupted compliance with LEED v5 monitoring requirements.
