What is the primary function of an anemometer?

• A. To measure building temperature
• B. To measure humidity levels
• C. To measure velocity airflow
• D. To measure pressure differences

Answer: (C)

The primary function of an anemometer is to measure velocity airflow. An anemometer is a crucial instrument used in various fields, particularly in HVAC and building performance testing, to determine the speed of air movement. Understanding airflow velocity is vital for ensuring adequate ventilation, identifying potential air leaks, and assessing the overall efficiency of an HVAC system. This measurement is particularly important in building airtightness testing because it helps quantify how air moves through a building's envelope. By knowing the airflow velocity, testers can calculate the volume of air exchanged and assess how this impacts the energy efficiency and comfort levels within the building. This kind of information is essential for creating a well-functioning building that minimizes energy loss and maximizes comfort.
