Autonomous building is a type of building that can take care of itself without a lot of help from people. It uses special machines and technologies to run things such as the lighting, temperature, security, and energy use. It can also be set up to recognize when something isn't working correctly and fix it on its own. Autonomous building is a way to make buildings smarter and more efficient, so that people can save money on energy costs and still have a comfortable and secure place to live or work.
