Answer:
Ventilation refers to the exchange of indoor and outdoor air. Without proper ventilation, an otherwise insulated and airtight house will seal in harmful pollutants, such as carbon monoxide, and moisture that can damage a house. Proper ventilation helps keep a home energy-efficient, safe, and healthy.
Explanation:
Buildings need ventilation so harmful chemicals don't stay trapped in there. Poor ventilation will result in an eventual build up of carbon dioxide and little oxygen, which means you could suffer from shortness of breath, headaches and fatigue.
