This paper reports on an investigation of the use of an innovative earth tube ventilation system designed to improve the internal comfort conditions without the need for mechanical cooling. The numerical model and computer simulation developed for the prediction of air and soil temperatures has been made. The paper demonstrates the accuracy of this model and describes the results of analysis.
