Parametric Study of the Thermal Performance of a Single-family House Equipped with an Airflow Window integrating a Heated Glazing

Airflow windows equipped with heated glazing offer the possibility to partly recover at the same time thermal losses through the window as well as the heated glass ones. Indeed, heat is recovered by the fresh air coming from the outside and flowing between the window panes before its introduction into the building. Using a two-dimensional nodal model of the airflow window coupled to a single-family house thermal one, parametric studies have been carried out in order to evaluate the performance of the heated airflow window in terms of heating energy consumption. A slight increase of heating energy is observed depending on the windows exposure and the climate compare to non-heated airflow windows cases with electric convectors as a heating system. Comparisons to conventional double-glazed windows were also performed. Results show that it is more efficient in comparison to a double-glazed window case. It can be an alternative to conventional electric heating solutions and is suitable for buildings with a high air tightness.
