Healthy building

A healthy building is a structure designed to help people who use it stay safe and healthy. This means that a building should have good air quality, plenty of natural light and fresh air coming in, and a design that encourages people to use stairs instead of elevators. It should also have space for good physical activity and enough space for people to move around without tripping over each other. In addition, the building should use materials that won't make people sick or cause allergies. Lastly, the building should make sure to use energy efficiently so that it doesn't waste electricity or heat or cool the building too much.
