Tip: Enjoy the cool breeze and save energy with a fan

22 August 2023

Did you know that an electric fan uses less electricity than air conditioning? Twenty times less! And the climate impact of a fan is much lower because it doesn’t contain any coolant. Aircon cools inside but moves heat outside whereas the airflow from a fan makes you feel cooler without cooling the air. 

Reason therefore to choose a fan rather than a portable air conditioner if you are in a building that doesn’t have a central air conditioning system.

Anneke Vermeulen who works at the Oude UB building is pleased to know that fans have such a low environmental impact. ‘In the past I was irritated that we didn’t have aircon but now I know that they guzzle energy I’m all too pleased to use the fan.’
