# Add Ceiling Fan

## Description
Install ceiling fans in buildings to increase air circulation. Ceiling fans effectively cool by introducing slow movement to induce evaporative cooling, rather than directly conditioning the air. A diversity factor is added to consider the simultaneous usage among the household.

## Modeler Description
Ceiling fan is modeled by increasing air velocity in the People objects and adding electric equipment to consider extra fan energy use. Cooling setpoint is increased by certain degrees in the presence of ceiling fans. A schedule is also introduced to simulate ceiling fan operation. A diversity factor (different in commercial and residential buildings) is added to consider the simultaneous usage among the building/household.
