What Is a Smart Building? (Super Simple Explanation)
A smart building is a building that can think a little bit.
It has small eyes (sensors) that watch temperature, lights, air, and people.
When the room is empty the lights turn off by themselves.
When it gets too hot the air conditioning turns on just enough.
When someone walks in the door the lights say “Hello, welcome!”
That is all a smart building does. It is kind to the planet and kind to your wallet.
Here are five easy things a smart building does every day:
1 Turns lights off when nobody is there
2 Keeps the air fresh so you don’t feel sleepy
3 Locks doors only for the right people
4 Tells the boss if there is a water leak
5 Uses less electricity so the bill is smaller
People also ask what is a smart building? Now you know – it is a friendly building that helps you without you asking.
