Natural Ventilation

Definition

Natural ventilation refers to the process of supplying and removing air through passive means, relying on natural forces such as wind and temperature differences. This approach reduces the need for mechanical heating and cooling systems, promoting energy efficiency and improving indoor air quality in buildings. By harnessing outdoor airflow, natural ventilation contributes significantly to the design and sustainability of green warehouses.
