Effect of obstacles on the crawl space airflow

One type of building foundation is a crawl space. This system is widespread in Scandinavia, but in recent years it has been used in the Czech Republic. A crawl space is a building foundation system where there is an air gap between the building and the ground. Both the design of the structure and the proper use is important for the proper functioning of the crawl space. Any obstacle can affect the airflow in the crawl space. This paper deals with simulations of airflow and age of air with the placement of obstacles in the crawl space.
