Economic and thermal technical comparison of classical foundation and foundation on air gap-crawl space

摘要

Foundation of the house is one of the most important things. There are two significant aspects. First is static one and the second is our aim, that is, thermal technical aspect. The main topic of the article is setting up wooden buildings over an air gap-crawl space. This type of foundation is commonly used in United States, and we would like to verify it in climatic condition of the Czech Republic. Crawl space has advantages such as ventilation of water vapor or readily available technical networks. Furthermore, this type of foundation is compared with usual method foundation on footings (strips). There are two modeled details of foundation that differ in the way of the foundation and composition of the floor. Construction details are analyzed in the software and then evaluated in terms of thermal technical and economic point of view.
