Comparison between ceiling fans and air conditioning or floor-standing fans (Extracts from the BRISE report)
In mainland France, particularly but not exclusively in the Mediterranean area, the penetration rate of ceiling fans is low, while air conditioning is developing very rapidly in the residential sector, following strong penetration in the tertiary sector.
Ceiling fans are still a very underdeveloped technology in these areas, even though they are even more relevant than in the French overseas departments, since they can replace air conditioning altogether, always in conjunction with a bioclimatic approach.
