āThe 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.ā
