Comfort

Big Ass Fans provide a cooling effect of up to 6°C, reducing the risk of heat stress. It also helps to destratify air in the winter. It can be used with or without HVAC systems.

SUSTAINABILITY

Big Ass Fans are fail-safe for HVAC systems, restoring optimal comfort levels quickly using high-volume, low-speed (HVLS) technology. As a result, it can increase efficiency for both employees and facilities.

RESILIENCY

Using Big Ass Fans leads to energy savings in HVAC systems or allows for no HVAC use. The use of fans for cooling results in 70% less energy consumption compared to HVAC. Additionally, using high-volume low-speed (HVLS) technology can save up to 30% on energy bills, even in the winter, through destratification.

“The volume of space requiring conditioning posed concerns about temperature stratification, cold downdrafts in the winter, and sprinkler pipe freezing. Big Ass Fans provided us with a model of our space to demonstrate how a few fans underneath the skylights would circulate the air to address these challenges and eliminate the need to install expensive heating elements along the skylight edges.”
