Fire Life Safety

Fan tracking measures supply and return airflows. The return-fan capacity is controlled to maintain a constant difference between supply and return airflow. The method is appealing because it measures the quantities of interest more or less directly. As previously mentioned, the direct-measurement method does not always measure low air velocities accurately; however, fan tracking reduces this risk by measuring airflow at duct velocity. Nevertheless, the method has been criticized because inaccurate outside-air-quantity measurements are the result of the cumulative inaccuracy of two independent measurements (supply and return airflow). Additionally, the method applies only to systems that have return fans. Heating, ventilating, and air-conditioning (HVAC systems) account for 39% of the energy used in commercial buildings in the United States. Consequently, almost any business or government agency has the potential to realize significant savings by improving its control of HVAC operations and improving the efficiency of the system it uses.

Proper performance and energy-efficient operation of HVAC systems can only be ensured through a successful O&M program. The building design team should provide systems that will perform effectively at the level of maintenance that the owner can provide. In turn, the owner must understand that different components of the HVAC system will require different degrees of maintenance to perform properly.
