There are two things that people want to resolve today: get proper ventilation against crazy climate changes and reduce energy consumption. Air conditioning is at its peak during hot days and apparently thanks to climate change, we no longer know when that is. In fact, if before you knew which months that your air conditioner would be less utilized, now you have to consider using it extensively.

So how do people address this? Well there is the usual ceiling fans which may solve this problem. Known to be lesser in energy consumption, they have their ways of providing the proper room temperature in your home. Some homes have them while others are contemplating on it. After reading this, do not be surprised if you find yourself rushing to the nearest store to get one and install it immediately.

Ceiling fans reduce energy consumption by decreasing the use of air conditioning. In summer, they create a downdraft which increases the rate of evaporation of moisture on the skin. In the winter, they de-stratify the air, displacing the heated layer that rises to the ceiling with cooler air from the lower levels of the room.

Fans are operated with a clockwise rotation in the winter to create an updraft and counter clockwise direction in the summer to create downdraft. This direction is determined as you look up at the fan.

The amount of air movement is a function of the size of the blades and their pitch, which varies from about

12 to 20 degrees, says Goemans. Other factors include the distance from the ceiling and between the blades, as well as the length of the blades to the size of the room.
