Energy and Indoor Air Quality (IAQ) Standards and Codes require air balance and control in buildings. EBTRON airflow measurement stations (AFMS) are designed to provide traverse and total measurements in locations that are hard to access or limited in straight ducts. When networked, the transmitter will provide airflow and temperature traverse. The Gold series enables connection through Bluetooth. By using the free EB-Link app, you can instantly access total flow, traverse data, velocity-weighted temperature, and when equipped with an optional humidity sensor, velocity-weighted enthalpy, relative humidity, and dewpoint.

Air balance requirements and validation:

• VAV and multispeed constant volume systems (supply fan airflow control) require dynamic outdoor air strategies to maintain and validate minimum ventilation requirements.
• Demand Control Ventilation (DCV) must provide ventilation for the actual population and building area.
• Occupied Standby Control shuts off ventilation to spaces and impacts supply fan airflow and outdoor air ventilation requirements.
• Exhaust pressurization requires exhaust rates to be maintained higher than supply rates, obligating tracking of systems.
• Building exfiltration requirements necessitate total outdoor intake to exceed the total exhaust under all dynamic load and reset conditions.
• Return and relief fan control shall maintain building pressurization by working cooperatively with ventilation.
• Economizers require fault detection and diagnostics (FDD), with limits on pressurization and the relief of excess air.
• Tighter envelope requirements limit air leakage and emphasize mechanical system airflow control.
• Natural ventilation is required to integrate with mechanical ventilation to ensure indoor IAQ under all dynamic conditions.
• A CO2 sensor can only detect a specific level of dilution in the air and is unable to determine the source of the air or maintain optimal building and space pressurization. Moreover, it is a delayed indicator of occupancy and ventilation and cannot directly identify whether there is under-ventilation or over-ventilation.
