Running HVLS fans in the forward direction creates optimal air movement that reduces the effective temperature (how hot you feel) by 8ºF. This allows you to increase your thermostat setting without compromising comfort. It also makes non-conditioned spaces bearable.
Worker productivity drops when people become uncomfortably hot. Airflow maximizes the body’s natural means of cooling—evaporative cooling—making people far more comfortable.
Running large commercial ceiling fans in reverse generates a gentle updraft which forces the warm air off the ceiling and down into the occupied space.
