1. Indoor environments affect outdoor environments, and vice versa. Research one aspect of building construction or interior design that affects the outside environment.
2. It is important for buildings to be designed to bring in fresh air. When carbon dioxide levels are too high, buildings get stuffy and people get headaches and feel sleepy. How do outdoor carbon dioxide levels affect the amount of fresh air that people need to bring into buildings?
3. In what ways are food quality and food safety global issues?
