Transitional public spaces, such as airport terminals, consume considerable energy resources and induce a large carbon footprint. The application of passive strategies, particularly the use of natural ventilation, to reduce operational energy use can be an effective strategy to reduce the environmental impacts of these spaces and reduce the capital, maintenance and replacement costs associated with these large spaces. This work investigates the feasibility of natural ventilation as a passive cooling strategy in an airport terminal. This preliminary study identifies opening sizes for a hypothetical airport terminal in Kinmen County, China. It is observed that large openings are required in June compared to July and August. Detailed computational simulations and field measurement studies can help provide more tailored natural ventilation solutions for airport terminal buildings.
