A complete numerical model for the prediction of air and soil temperature fields under a building is developed. The model describes the simultaneous heat and mass transfer inside an earth-tube system and into the soil, taking into account the soil's natural thermal stratification. The proposed model is validated against two experimental data sets and is found accurate. The proposed algorithms were developed within the TRNSYS environment and can be easily coupled with building or greenhouse simulation codes for the description of earth-tube heat exchangers' determinant parameters.
