Thermal Dynamic Insulation: Numerical Modeling in a Transient Regime and Application to Alternative Aviary Houses

The paper proposes a numerical model for investigating the energy performance of thermal dynamic insulation in transient conditions. This technology consists of porous building components that are permeable to airflow, ensuring high levels of energy performance and IAQ. The model is implemented in MATLAB environment and allows an accurate evaluation of heat transfer through porous media, with the final purpose of quantifying the energy benefits deriving from dynamic insulation. Beyond its presentation, the model is used to investigate the implementation of a dynamically-insulated ceiling to an alternative aviary house for laying-hens, located in Des Moines, Iowa (U.S.). The proposed system produces thermal, energy and economical savings in both cold and warm seasons.
