Summary Energy crisis is one of the major obstacles for human development. There are on-going researches to overcome this for a sustainable environment and economy. Passive air cooling system of earth pipe cooling is seen as a viable energy efficient technology for hot and humid subtropical climates. It can be an attractive economical alternative to conventional cooling since there are no compressors or any habitual mechanical unit. It utilizes earth’s near constant underground temperature to cool air for residential, agricultural or industrial uses. This paper reports the thermal performance of earth pipe cooling technology for a hot and humid subtropical climatic zone in Queensland, Australia. A series of pipes buried underground were used in order to increase the cooling performance of the system. To measure the thermal performance, a thermal model was developed for the earth pipe cooling system and simulated using ANSYS Fluent. Data were collected from two modelled rooms built from shipping containers and installed at Central Queensland University, Rockhampton, Australia. The impact of air temperature and velocity on room cooling performance has also been assessed. A significant temperature reduction is seen in this study, which will save energy cost for thermal cooling in buildings.
