Okay kiddo, have you ever been in a room that felt too hot or too cold? Well, Ashrae 55 is like a set of rules that tells people who design buildings how to make sure rooms always feel just right, not too hot or too cold.
It's like the story of Goldilocks and the Three Bears. Remember how Goldilocks tried the porridge and one was too hot, another too cold, and the third was just right? Ashrae 55 helps builders and designers make sure the temperature in a room is just right for the people who will use it.
But it's not just about temperature. Ashrae 55 also has rules for things like humidity, which is the amount of water in the air. Just like Goldilocks didn't want her porridge too watery or too dry, people don't want the air in a building to be too humid or too dry.
So Ashrae 55 helps builders and designers make sure everything is just right for the people who will be using a building. It's like a set of rules to make sure everyone is comfortable and happy, just like Goldilocks!
