A building is ‘sustainable’ if it uses less energy and hurts the planet less. It's like a house that drinks water from a well instead of using a big, dirty river. Sustainable buildings use materials we can reuse or recycle, and they let in light from the sun to save on lights at night.
Examples
- A building made mostly from bricks that are made out of recycled plastic bottles
