Validation of a coupled two-model system for a prediction of indoor air temperature variation.

In this paper, a calibration and validation of the newly formulated model for prediction of indoor air temperature is presented. The construction of the model is based on the interconnection between two independent models – first for calculation of heat transfer rate through opaque building envelope, the second for calculation of indoor temperature from user-defined building envelope parameters. The model introduces several simplifications and therefore the validation is essential to prove its capability of solving indoor air related problems. The calibration, which was done on series of data taken form in-situ measurement, allowed for model adjustment and subsequent validation. As the agreement between predicted and experimentally determined room temperature was less than 1 °C the model can be considered as being capable of solving tasks and problems in the field of building engineering.
