Abstract (EN): This paper presents some of the findings of a wider study on a ventilated double window as a system to pre-heat the ventilation air. The study focused on the design aspects of this system as a function of airflow pattern generated by stack and wind effect. Experimental measurements of the thermal performance of the ventilated double window were carried out in an outdoor environment in the winter season. In the experiments, the outside and inside temperatures, the airflow rate and also the temperatures distribution along the window ventilated cavity were measured every minute. In this paper, some of the experimental results are presented. Field results from this study are expected to help designers to conceive ventilated double windows duly adapted to local climate where ventilation is an important design consideration and heat loss must be reduced. The tested system proved to be able to contribute significantly for this reduction.
