This technical guide does not cover all codes and standards related to fans and air movement published worldwide, and it highlights only several commonly used materials for references and examples. It is also noted that the usage of these materials could be subjected to variations by countries. Users are advised to implement these materials with caution.
Environmental conditions
ASHRAE Standard 55 – Thermal Environmental Conditions for Human Occupancy (2020) identifies factors that may affect thermal comfort in an indoor environment. Proposed in ASHRAE 55, the standard effective temperature (SET) is a reliable index in estimating the heat loss effect for increased air speed conditions.
Green Mark is a green building certification scheme established in Singapore to raise energy performance standards and emphasize other sustainability outcomes. suggests the indoor temperature setpoint could maintain at 26 °C [79 °F] or above if the space is designed with elevated air speed.
Ceiling fans testing regulations
specifies the instrumentation, facilities, test installation methods, and procedures to determine ceiling fan application data for occupant thermal comfort in a space.
Performance testing on small-diameter ceiling fans (≤ 2.1 m [7 ft]) is recommended by the .
Performance testing on large-diameter ceiling fans (> 2.1 m [7 ft]) is standardized by the .
A modified testing method for large-diameter fans, the , is developed to enhance ceiling fan testing effectiveness. CFEI is derived from the fan energy index equation in with substitute coefficient for large-diameter ceiling fans.
Fire safety
The primary concern with ceiling fans about the fire code is the interaction with fire sprinklers. The National Fire Protection Association (NFPA) Standards, , summarizes the requirements of ceiling fan installation concerning fire sprinklers in buildings. It is noted that specific fire safety requirements may vary by country. Users should always consult local codes and requirements for a specific project.
Seismic requirements
Seismic considerations and requirements are especially relevant for installations of ceiling fans, especially for large-diameter fans, long suspension rods, or other requirements for seismic support. An example can be found in the . Users should always consult local codes and requirements for a specific project.
